What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D. The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review? A literature could be written to accomplish different aims:

To develop a theory or evaluate an existing theory
To summarize the historical or existing state of a research topic
Identify a problem in a field of research

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews . Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

A research paper assigned in a course
A thesis or dissertation
A grant proposal
An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework: 10.1177/08948453211037398

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

Example : The effect of leave policies on increasing fertility: a systematic review: 10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

Example : Employment Instability and Fertility in Europe: A Meta-Analysis: 10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts . Journal of Advanced Nursing , 53 (3), 311-318.

Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis: 10.1177/05390184221113735

A literature review surveys prior research published in books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated. Literature reviews are designed to provide an overview of sources you have used in researching a particular topic and to demonstrate to your readers how your research fits within existing scholarship about the topic.

Importance of a Good Literature Review

A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:

Give a new interpretation of old material or combine new with old interpretations,
Trace the intellectual progression of the field, including major debates,
Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.

Given this, the purpose of a literature review is to:

Place each work in the context of its contribution to understanding the research problem being studied.
Describe the relationship of each work to the others under consideration.
Identify new ways to interpret prior research.
Reveal any gaps that exist in the literature.
Resolve conflicts amongst seemingly contradictory previous studies.
Identify areas of prior scholarship to prevent duplication of effort.
Point the way in fulfilling a need for additional research.
Locate your own research within the context of existing literature [very important].

Types of Literature Reviews

It is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally among scholars that become part of the body of epistemological traditions within the field.

In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews. Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.

Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply embedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].

Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses or research problems. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication. This is the most common form of review in the social sciences.

Historical Review Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.

Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis]. Reviewing methods of analysis provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.

Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyze data from the studies that are included in the review. The goal is to deliberately document, critically evaluate, and summarize scientifically all of the research about a clearly defined research problem . Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?" This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.

Theoretical Review The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

NOTE : Most often the literature review will incorporate some combination of types. For example, a review that examines literature supporting or refuting an argument, assumption, or philosophical problem related to the research problem will also need to include writing supported by sources that establish the history of these arguments in the literature.

Structure and Writing Style

I. Thinking About Your Literature Review

The structure of a literature review should include the following in support of understanding the research problem :

An overview of the subject, issue, or theory under consideration, along with the objectives of the literature review,
Division of works under review into themes or categories [e.g. works that support a particular position, those against, and those offering alternative approaches entirely],
An explanation of how each work is similar to and how it varies from the others,
Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research.

The critical evaluation of each work should consider :

Provenance -- what are the author's credentials? Are the author's arguments supported by evidence [e.g. primary historical material, case studies, narratives, statistics, recent scientific findings]?
Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem? Was the sample size appropriate? Were the results effectively interpreted and reported?
Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?
Persuasiveness -- which of the author's theses are most convincing or least convincing?
Validity -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?

II. Development of the Literature Review

Four Basic Stages of Writing 1. Problem formulation -- which topic or field is being examined and what are its component issues? 2. Literature search -- finding materials relevant to the subject being explored. 3. Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. 4. Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.

Consider the following issues before writing the literature review: Clarify If your assignment is not specific about what form your literature review should take, seek clarification from your professor by asking these questions: 1. Roughly how many sources would be appropriate to include? 2. What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? 3. Should I summarize, synthesize, or critique sources by discussing a common theme or issue? 4. Should I evaluate the sources in any way beyond evaluating how they relate to understanding the research problem? 5. Should I provide subheadings and other background information, such as definitions and/or a history? Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you've already read, such as required readings in the course syllabus, are also excellent entry points into your own research. Narrow the Topic The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make the act of reviewing easier if you first limit scope of the research problem. A good strategy is to begin by searching the USC Libraries Catalog for recent books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.

III. Ways to Organize Your Literature Review

Chronology of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic [“conceptual categories”] A thematic literature review is the most common approach to summarizing prior research in the social and behavioral sciences. Thematic reviews are organized around a topic or issue, rather than the progression of time, although the progression of time may still be incorporated into a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it would still be organized chronologically reflecting technological developments in media. The difference in this example between a "chronological" and a "thematic" approach is what is emphasized the most: themes related to the role of the Internet in presidential politics. Note that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point being made. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.

Other Sections of Your Literature Review Once you've decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. However, only include what is necessary for the reader to locate your study within the larger scholarship about the research problem.

Here are examples of other sections, usually in the form of a single paragraph, you may need to include depending on the type of review you write:

Current Situation : Information necessary to understand the current topic or focus of the literature review.
Sources Used : Describes the methods and resources [e.g., databases] you used to identify the literature you reviewed.
History : The chronological progression of the field, the research literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
Selection Methods : Criteria you used to select (and perhaps exclude) sources in your literature review. For instance, you might explain that your review includes only peer-reviewed [i.e., scholarly] sources.
Standards : Description of the way in which you present your information.
Questions for Further Research : What questions about the field has the review sparked? How will you further your research as a result of the review?

IV. Writing Your Literature Review

Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.

Use Evidence A literature review section is, in this sense, just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence [citations] that demonstrates that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Related items that provide additional information, but that are not key to understanding the research problem, can be included in a list of further readings . Use Quotes Sparingly Some short quotes are appropriate if you want to emphasize a point, or if what an author stated cannot be easily paraphrased. Sometimes you may need to quote certain terminology that was coined by the author, is not common knowledge, or taken directly from the study. Do not use extensive quotes as a substitute for using your own words in reviewing the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each thematic paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to your own work and the work of others. Keep Your Own Voice While the literature review presents others' ideas, your voice [the writer's] should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work.

V. Common Mistakes to Avoid

These are the most common mistakes made in reviewing social science research literature.

Sources in your literature review do not clearly relate to the research problem;
You do not take sufficient time to define and identify the most relevant sources to use in the literature review related to the research problem;
Relies exclusively on secondary analytical sources rather than including relevant primary research studies or data;
Uncritically accepts another researcher's findings and interpretations as valid, rather than examining critically all aspects of the research design and analysis;
Does not describe the search procedures that were used in identifying the literature to review;
Reports isolated statistical results rather than synthesizing them in chi-squared or meta-analytic methods; and,
Only includes research that validates assumptions and does not consider contrary findings and alternative interpretations found in the literature.

Writing Tip

Break Out of Your Disciplinary Box!

Thinking interdisciplinarily about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, particularly in the social sciences, thinking about research problems from multiple vectors is a key strategy for finding new solutions to a problem or gaining a new perspective. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.

Frodeman, Robert. The Oxford Handbook of Interdisciplinarity . New York: Oxford University Press, 2010.

Another Writing Tip

Don't Just Review for Content!

While conducting a review of the literature, maximize the time you devote to writing this part of your paper by thinking broadly about what you should be looking for and evaluating. Review not just what scholars are saying, but how are they saying it. Some questions to ask:

How are they organizing their ideas?
What methods have they used to study the problem?
What theories have been used to explain, predict, or understand their research problem?
What sources have they cited to support their conclusions?
How have they used non-textual elements [e.g., charts, graphs, figures, etc.] to illustrate key points?

When you begin to write your literature review section, you'll be glad you dug deeper into how the research was designed and constructed because it establishes a means for developing more substantial analysis and interpretation of the research problem.

Hart, Chris. Doing a Literature Review: Releasing the Social Science Research Imagination . Thousand Oaks, CA: Sage Publications, 1 998.

Yet Another Writing Tip

When Do I Know I Can Stop Looking and Move On?

Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature:

Look for repeating patterns in the research findings . If the same thing is being said, just by different people, then this likely demonstrates that the research problem has hit a conceptual dead end. At this point consider: Does your study extend current research? Does it forge a new path? Or, does is merely add more of the same thing being said?
Look at sources the authors cite to in their work . If you begin to see the same researchers cited again and again, then this is often an indication that no new ideas have been generated to address the research problem.
Search Google Scholar to identify who has subsequently cited leading scholars already identified in your literature review [see next sub-tab]. This is called citation tracking and there are a number of sources that can help you identify who has cited whom, particularly scholars from outside of your discipline. Here again, if the same authors are being cited again and again, this may indicate no new literature has been written on the topic.

What is a Literature Review?

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field.

A literature review should:

Provide a comprehensive and updated review of the literature;
Explain why this review has taken place;
Articulate a position or hypothesis;
Acknowledge and account for conflicting and corroborating points of view

From S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

Demonstrate how a study fills a gap in research
Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

Organizes or describes a topic
Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
It may be too focused. Some niche studies may miss the bigger picture.
It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

Writing a Literature Review

Welcome to the Purdue OWL

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

An introductory paragraph that explains what your working topic and thesis is
A forecast of key topics or texts that will appear in the review
Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
Critically Evaluate: Mention the strengths and weaknesses of your sources
Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

Summarize the key findings you have taken from the literature and emphasize their significance
Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
Qualitative versus quantitative research
Empirical versus theoretical scholarship
Divide the research by sociological, historical, or cultural sources
Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

Search for relevant literature
Evaluate sources
Identify themes, debates and gaps
Outline the structure
Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

Why write a literature review, examples of literature reviews, step 1: search for relevant literature, step 2: evaluate and select sources, step 3: identify themes, debates and gaps, step 4: outline your literature review’s structure, step 5: write your literature review, frequently asked questions about literature reviews, introduction.

Quick Run-through
Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

Demonstrate your familiarity with the topic and scholarly context
Develop a theoretical framework and methodology for your research
Position yourself in relation to other researchers and theorists
Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
Body image, self-perception, self-esteem, mental health
Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

Your university’s library catalogue
Google Scholar
Project Muse (humanities and social sciences)
Medline (life sciences and biomedicine)
EconLit (economics)
Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

What question or problem is the author addressing?
What are the key concepts and how are they defined?
What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
What are the results and conclusions of the study?
How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

Prevent plagiarism, run a free check.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
Themes: what questions or concepts recur across the literature?
Debates, conflicts and contradictions: where do sources disagree?
Pivotal publications: are there any influential theories or studies that changed the direction of the field?
Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

Most research has focused on young women.
There is an increasing interest in the visual aspects of social media.
But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

Look at what results have emerged in qualitative versus quantitative research
Discuss how the topic has been approached by empirical versus theoretical scholarship
Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
Critically evaluate: mention the strengths and weaknesses of your sources.
Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

To familiarise yourself with the current state of knowledge on your topic
To ensure that you’re not just repeating what others have already done
To identify gaps in knowledge and unresolved problems that your research can address
To develop your theoretical framework and methodology
To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a review and synthesis of existing research on a topic or research question. A literature review is meant to analyze the scholarly literature, make connections across writings and identify strengths, weaknesses, trends, and missing conversations. A literature review should address different aspects of a topic as it relates to your research question. A literature review goes beyond a description or summary of the literature you have read.

Literature Review in Research Writing

Table of Contents

Research on research? If you find this idea rather peculiar, know that nowadays, with the huge amount of information produced daily all around the world, it is becoming more and more difficult to keep up to date with all of it. In addition to the sheer amount of research, there is also its origin. We are witnessing the economic and intellectual emergence of countries like China, Brazil, Turkey, and United Arab Emirates, for example, that are producing scholarly literature in their own languages. So, apart from the effort of gathering information, there must also be translators prepared to unify all of it in a single language to be the object of the literature survey. At Elsevier, our team of translators is ready to support researchers by delivering high-quality scientific translations , in several languages, to serve their research – no matter the topic.

What is a literature review?

A literature review is a study – or, more accurately, a survey – involving scholarly material, with the aim to discuss published information about a specific topic or research question. Therefore, to write a literature review, it is compulsory that you are a real expert in the object of study. The results and findings will be published and made available to the public, namely scientists working in the same area of research.

How to Write a Literature Review

First of all, don’t forget that writing a literature review is a great responsibility. It’s a document that is expected to be highly reliable, especially concerning its sources and findings. You have to feel intellectually comfortable in the area of study and highly proficient in the target language; misconceptions and errors do not have a place in a document as important as a literature review. In fact, you might want to consider text editing services, like those offered at Elsevier, to make sure your literature is following the highest standards of text quality. You want to make sure your literature review is memorable by its novelty and quality rather than language errors.

Writing a literature review requires expertise but also organization. We cannot teach you about your topic of research, but we can provide a few steps to guide you through conducting a literature review:

Choose your topic or research question: It should not be too comprehensive or too limited. You have to complete your task within a feasible time frame.
Set the scope: Define boundaries concerning the number of sources, time frame to be covered, geographical area, etc.
Decide which databases you will use for your searches: In order to search the best viable sources for your literature review, use highly regarded, comprehensive databases to get a big picture of the literature related to your topic.
Search, search, and search: Now you’ll start to investigate the research on your topic. It’s critical that you keep track of all the sources. Start by looking at research abstracts in detail to see if their respective studies relate to or are useful for your own work. Next, search for bibliographies and references that can help you broaden your list of resources. Choose the most relevant literature and remember to keep notes of their bibliographic references to be used later on.
Review all the literature, appraising carefully it’s content: After reading the study’s abstract, pay attention to the rest of the content of the articles you deem the “most relevant.” Identify methodologies, the most important questions they address, if they are well-designed and executed, and if they are cited enough, etc.

If it’s the first time you’ve published a literature review, note that it is important to follow a special structure. Just like in a thesis, for example, it is expected that you have an introduction – giving the general idea of the central topic and organizational pattern – a body – which contains the actual discussion of the sources – and finally the conclusion or recommendations – where you bring forward whatever you have drawn from the reviewed literature. The conclusion may even suggest there are no agreeable findings and that the discussion should be continued.

Why are literature reviews important?

Literature reviews constantly feed new research, that constantly feeds literature reviews…and we could go on and on. The fact is, one acts like a force over the other and this is what makes science, as a global discipline, constantly develop and evolve. As a scientist, writing a literature review can be very beneficial to your career, and set you apart from the expert elite in your field of interest. But it also can be an overwhelming task, so don’t hesitate in contacting Elsevier for text editing services, either for profound edition or just a last revision. We guarantee the very highest standards. You can also save time by letting us suggest and make the necessary amendments to your manuscript, so that it fits the structural pattern of a literature review. Who knows how many worldwide researchers you will impact with your next perfectly written literature review.

A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory; thereby, provides a description, summary, and critical evaluation of the works in relation to the research problem being investigated. Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic and to demonstrate to your readers how your research fits within a larger field of study.

Some more thoroughly detailed sources to follow for developing a literature review would be Conducting Research Literature Reviews and/or Doing a Literature Review by Chris Hart — both of which are located in our Squires Library collection.

Fink, Arlene. Conducting Research Literature Reviews : From the Internet to Paper . Thousand Oaks, CA: SAGE, 1998.

Hart, Chris. Doing a literature review : releasing the social science research imagination London: SAGE, 2005

A literature review may consist of simply a summary of key sources, but in many disciplines, a literature review has an organizational pattern and combines both a summary and a synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, whereas a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:

Give a new interpretation of old material or combine new with old interpretations,
Trace the intellectual progression of the field, including major debates,
Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.

The purpose of a literature review is to:

Place each work in the context of its contribution to understanding the research problem being studied.
Describe the relationship of each work to the others under consideration.
Identify new ways to interpret prior research.
Reveal any gaps that exist in the literature.
Reveal conflicts amongst seemingly contradictory previous studies.
Identify areas of prior scholarship to prevent duplication of effort.
Point the way in fulfilling a need for additional research. This is often directly related to the gap(s) revealed .
Locate your own research idea(s) / intent within the context of existing literature [very important].

Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply imbedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].

I. Thinking About Your Literature Revie w

The structure of a literature review should include the following :

An overview of the subject, issue, or theory under consideration, along with the objectives of the literature review,
Division of works under review into themes or categories [e.g. works that support a particular position, those against, and those offering alternative approaches entirely],
An explanation of how each work is similar to and how it varies from the others,
Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research.

The critical evaluation of each work should consider :

Provenance -- what are the author's credentials? Are the author's arguments supported by evidence [e.g. primary historical material, case studies, narratives, statistics, recent scientific findings]?
Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem? Was the sample size appropriate? Were the results effectively interpreted and reported?
Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?
Persuasiveness -- which of the author's theses are most convincing or least convincing?
Value -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?

II. Development of the Literature Review

Four Stages 1. Problem formulation -- which topic or field is being examined and what are its component issues? 2. Literature search -- finding materials relevant to the subject being explored. 3. Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. 4. Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.

This video can be of assistance as it provides direction for literature review planning, processing, and writing - Video Additionally, the speaker on the previous video, did one on Literature Review Basics: 7 Major Mistakes To Avoid — however, beware, this video is so thorough, that it is 1 hr in length. Either plan an hour or split the time up to view the content in portions.

Address the following matters prior to writing the literature review: Clarify If your assignment is not very specific about what form your literature review should take, seek clarification from your professor by asking these questions:

1. Roughly how many sources should I include?

2. What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)?

3. Should I summarize, synthesize, or critique sources by discussing a common theme or issue?

5. Should I provide subheadings and other background information, such as definitions and/or a history

6. Should the literature review address the theoretical framework (theory applied to the intended study)?

Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to attain a sense of the various themes you might want to look for in your own research or to identify ways to organize your final review. The reference section of sources you have already read are also excellent entry points into your own research. Narrow the Topic The narrower the topic of your study, the easier it will be to limit the source content types you need to read in order to develop a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, This is often because a limitation placed on the years of publications referenced. You will make your job easier if you first limit the scope of the research problem. A good strategy is to begin by searching the general area pertaining to the topic and review the abstracts, which can provide direction. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.

III. Ways to Organize Your Literature Review

Chronology of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic [“conceptual categories”] Thematic reviews of literature are organized around a topic or issue, rather than the progression of time. However, progression of time may still be an important factor in a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it will still be organized chronologically reflecting technological developments in media. The only difference here between a "chronological" and a "thematic" approach is what is emphasized the most: the role of the Internet in presidential politics. Note however that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point made. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.

Other Sections of Your Literature Review Once you have decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you but include only what is necessary for the reader to locate your study within the larger scholarship framework.

Here are examples of other sections you may need to include depending on the type of review you write:

Current Situation : information necessary to understand the topic or focus of the literature review.
History : the chronological progression of the field, the literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
Selection Methods : the criteria you used to select (and perhaps exclude) sources in your literature review. For instance, you might explain that your review includes only peer-reviewed articles and journals.
Standards : the way in which you present your information.
Questions for Further Research : What questions about the field has the review sparked? How will you further your research as a result of the review?

IV. Writing Your Literature Review

Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.

Use Evidence A literature review section is, in this sense, similar to other academic research papers. Your interpretation of the available sources must be backed up with evidence [citations] that demonstrates that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Related items that provide additional information but that are not key to understanding the research problem can often be included in a "further readings" section of the literature review. This should be within your instructor's guidelines, as not all want you to provide such as list. Use Quotes Sparingly Some short quotes are okay if you want to emphasize a point, or if what an author stated cannot be easily paraphrased. Sometimes you may need to quote certain terminology that was coined by the author, not common knowledge, or taken directly from the study. Lastly, it isn't out of the ordinary to find that an author has stated something that you want to reiterate but in the perfect phasing and you can find that a paraphrase will simply not do it as well. When you do quote, always assure that you provide the complete citation [name(s), year, page# / para#] ( if you are not yet familiar, the "para#) is when you are using an online source that is without page numbers - you then list the paragraph the quote came from. ) Lastly, do not use extensive quotes as a substitute for your own summary and interpretation of the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each thematic paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to your own work. Keep Your Own Voice While the literature review presents others' ideas, your voice [the writer's] should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work. [name, year]

V. Common Mistakes to Avoid

These are the most common mistakes made in reviewing social science research literature.

Sources in your literature review do not clearly relate to the research problem;
Not a sufficient amount of time was taken to define and identify the most relevant sources to use in the literature review related to the research problem;
The literature review relies exclusively on secondary analytical sources rather than including relevant primary research studies and/or data;
Uncritically accepts another researcher's findings and interpretations as valid, rather than examining critically all aspects of the research design and analysis;
Does not describe the search procedures that were used in identifying the literature to review;
Reports isolated statistical results rather than synthesizing them in chi-squared or meta-analytic methods; and,
Only includes research that validates assumptions and does not consider contrary findings and alternative interpretations found in the literature.

Break out of Your Disciplinary Box!

Thinking interdisciplinarily about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, thinking about research problems from multiple vectors is a key strategy for finding new solutions to a problem or gaining a new perspective. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.

Menken, S. B. J., (Ed.). An introduction to interdisciplinary research: Theory and practice . Amsterdam : Amsterdam University Press, 2016.

Don't Just Review for Content!

How are they organizing their ideas?
What methods have they used to study the problem?
What theories have been used to explain, predict, or understand their research problem?
What sources have they cited to support their conclusions?
How have they used non-textual elements [e.g., charts, graphs, figures, etc.] to illustrate key points?

Hart, Chris. Doing a Literature Review: Releasing the Social Science Research Imagination . Thousand Oaks, CA: Sage Publications, 1 998.

When Do I Know I Can Stop Looking and Move On?

Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature:

Look for repeating patterns in the research findings . If the same thing is being said, just by different people, then this likely demonstrates that the research problem has hit a conceptual dead end. At this point consider: Does your study extend current research? Does it forge a new path? Or, does is merely add more of the same thing being said?
Look at sources the authors cite to in their work . If you begin to see the same researchers cited again and again, then this is often an indication that no new ideas have been generated to address the research problem.
Search Google Scholar to identify who has subsequently cited leading scholars already identified in your literature review. This is called citation tracking and there are a number of sources that can help you identify who has cited whom, particularly scholars from outside of your discipline. Here again, if the same authors are being cited again and again, this may indicate no new literature has been written on the topic.

Steps in Conducting a Literature Review

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question. That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment. Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

Explains the background of research on a topic.
Demonstrates why a topic is significant to a subject area.
Discovers relationships between research studies/ideas.
Identifies major themes, concepts, and researchers on a topic.
Identifies critical gaps and points of disagreement.
Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question. The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

Make sure your research question is not too broad or too narrow. Is it manageable?
Begin writing down terms that are related to your question. These will be useful for searches later.
If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover?

This may depend on your assignment. How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search.

Where to find databases:

use the tabs on this guide
Find other databases in the Nursing Information Resources web page
More on the Medical Library web page
... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
Review the abstracts of research studies carefully. This will save you time.
Use the bibliographies and references of research studies you find to locate others.
Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
Ask your librarian for help at any time.
Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

What was the research question of the study you are reviewing? What were the authors trying to discover?
Was the research funded by a source that could influence the findings?
What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
If there are conflicting studies, why do you think that is?
How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips:

Review the abstracts carefully.
Keep careful notes so that you may track your thought processes during the research process.
Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

4-minute read

23rd October 2023

If you’re writing a research paper or dissertation , then you’ll most likely need to include a comprehensive literature review . In this post, we’ll review the purpose of literature reviews, why they are so significant, and the specific elements to include in one. Literature reviews can:

1. Provide a foundation for current research.

2. Define key concepts and theories.

3. Demonstrate critical evaluation.

4. Show how research and methodologies have evolved.

5. Identify gaps in existing research.

6. Support your argument.

Keep reading to enter the exciting world of literature reviews!

What is a Literature Review?

A literature review is a critical summary and evaluation of the existing research (e.g., academic journal articles and books) on a specific topic. It is typically included as a separate section or chapter of a research paper or dissertation, serving as a contextual framework for a study. Literature reviews can vary in length depending on the subject and nature of the study, with most being about equal length to other sections or chapters included in the paper. Essentially, the literature review highlights previous studies in the context of your research and summarizes your insights in a structured, organized format. Next, let’s look at the overall purpose of a literature review.

Literature reviews are considered an integral part of research across most academic subjects and fields. The primary purpose of a literature review in your study is to:

Provide a Foundation for Current Research

Since the literature review provides a comprehensive evaluation of the existing research, it serves as a solid foundation for your current study. It’s a way to contextualize your work and show how your research fits into the broader landscape of your specific area of study.

Define Key Concepts and Theories

The literature review highlights the central theories and concepts that have arisen from previous research on your chosen topic. It gives your readers a more thorough understanding of the background of your study and why your research is particularly significant .

Demonstrate Critical Evaluation

A comprehensive literature review shows your ability to critically analyze and evaluate a broad range of source material. And since you’re considering and acknowledging the contribution of key scholars alongside your own, it establishes your own credibility and knowledge.

Show How Research and Methodologies Have Evolved

Another purpose of literature reviews is to provide a historical perspective and demonstrate how research and methodologies have changed over time, especially as data collection methods and technology have advanced. And studying past methodologies allows you, as the researcher, to understand what did and did not work and apply that knowledge to your own research.

Identify Gaps in Existing Research

Besides discussing current research and methodologies, the literature review should also address areas that are lacking in the existing literature. This helps further demonstrate the relevance of your own research by explaining why your study is necessary to fill the gaps.

Support Your Argument

A good literature review should provide evidence that supports your research questions and hypothesis. For example, your study may show that your research supports existing theories or builds on them in some way. Referencing previous related studies shows your work is grounded in established research and will ultimately be a contribution to the field.

The Literature Review: A Foundation for High-Quality Medical Education Research

a These are subscription resources. Researchers should check with their librarian to determine their access rights.

Despite a surge in published scholarship in medical education 1 and rapid growth in journals that publish educational research, manuscript acceptance rates continue to fall. 2 Failure to conduct a thorough, accurate, and up-to-date literature review identifying an important problem and placing the study in context is consistently identified as one of the top reasons for rejection. 3 , 4 The purpose of this editorial is to provide a road map and practical recommendations for planning a literature review. By understanding the goals of a literature review and following a few basic processes, authors can enhance both the quality of their educational research and the likelihood of publication in the Journal of Graduate Medical Education ( JGME ) and in other journals.

The Literature Review Defined

In medical education, no organization has articulated a formal definition of a literature review for a research paper; thus, a literature review can take a number of forms. Depending on the type of article, target journal, and specific topic, these forms will vary in methodology, rigor, and depth. Several organizations have published guidelines for conducting an intensive literature search intended for formal systematic reviews, both broadly (eg, PRISMA) 5 and within medical education, 6 and there are excellent commentaries to guide authors of systematic reviews. 7 , 8

A literature review forms the basis for high-quality medical education research and helps maximize relevance, originality, generalizability, and impact.
A literature review provides context, informs methodology, maximizes innovation, avoids duplicative research, and ensures that professional standards are met.
Literature reviews take time, are iterative, and should continue throughout the research process.
Researchers should maximize the use of human resources (librarians, colleagues), search tools (databases/search engines), and existing literature (related articles).
Keeping organized is critical.

Such work is outside the scope of this article, which focuses on literature reviews to inform reports of original medical education research. We define such a literature review as a synthetic review and summary of what is known and unknown regarding the topic of a scholarly body of work, including the current work's place within the existing knowledge . While this type of literature review may not require the intensive search processes mandated by systematic reviews, it merits a thoughtful and rigorous approach.

Purpose and Importance of the Literature Review

An understanding of the current literature is critical for all phases of a research study. Lingard 9 recently invoked the “journal-as-conversation” metaphor as a way of understanding how one's research fits into the larger medical education conversation. As she described it: “Imagine yourself joining a conversation at a social event. After you hang about eavesdropping to get the drift of what's being said (the conversational equivalent of the literature review), you join the conversation with a contribution that signals your shared interest in the topic, your knowledge of what's already been said, and your intention.” 9

The literature review helps any researcher “join the conversation” by providing context, informing methodology, identifying innovation, minimizing duplicative research, and ensuring that professional standards are met. Understanding the current literature also promotes scholarship, as proposed by Boyer, 10 by contributing to 5 of the 6 standards by which scholarly work should be evaluated. 11 Specifically, the review helps the researcher (1) articulate clear goals, (2) show evidence of adequate preparation, (3) select appropriate methods, (4) communicate relevant results, and (5) engage in reflective critique.

Failure to conduct a high-quality literature review is associated with several problems identified in the medical education literature, including studies that are repetitive, not grounded in theory, methodologically weak, and fail to expand knowledge beyond a single setting. 12 Indeed, medical education scholars complain that many studies repeat work already published and contribute little new knowledge—a likely cause of which is failure to conduct a proper literature review. 3 , 4

Likewise, studies that lack theoretical grounding or a conceptual framework make study design and interpretation difficult. 13 When theory is used in medical education studies, it is often invoked at a superficial level. As Norman 14 noted, when theory is used appropriately, it helps articulate variables that might be linked together and why, and it allows the researcher to make hypotheses and define a study's context and scope. Ultimately, a proper literature review is a first critical step toward identifying relevant conceptual frameworks.

Another problem is that many medical education studies are methodologically weak. 12 Good research requires trained investigators who can articulate relevant research questions, operationally define variables of interest, and choose the best method for specific research questions. Conducting a proper literature review helps both novice and experienced researchers select rigorous research methodologies.

Finally, many studies in medical education are “one-offs,” that is, single studies undertaken because the opportunity presented itself locally. Such studies frequently are not oriented toward progressive knowledge building and generalization to other settings. A firm grasp of the literature can encourage a programmatic approach to research.

Approaching the Literature Review

Considering these issues, journals have a responsibility to demand from authors a thoughtful synthesis of their study's position within the field, and it is the authors' responsibility to provide such a synthesis, based on a literature review. The aforementioned purposes of the literature review mandate that the review occurs throughout all phases of a study, from conception and design, to implementation and analysis, to manuscript preparation and submission.

Planning the literature review requires understanding of journal requirements, which vary greatly by journal ( table 1 ). Authors are advised to take note of common problems with reporting results of the literature review. Table 2 lists the most common problems that we have encountered as authors, reviewers, and editors.

Object name is i1949-8357-8-3-297-t02.jpg

Locating and Organizing the Literature

Three resources may facilitate identifying relevant literature: human resources, search tools, and related literature. As the process requires time, it is important to begin searching for literature early in the process (ie, the study design phase). Identifying and understanding relevant studies will increase the likelihood of designing a relevant, adaptable, generalizable, and novel study that is based on educational or learning theory and can maximize impact.

Human Resources

A medical librarian can help translate research interests into an effective search strategy, familiarize researchers with available information resources, provide information on organizing information, and introduce strategies for keeping current with emerging research. Often, librarians are also aware of research across their institutions and may be able to connect researchers with similar interests. Reaching out to colleagues for suggestions may help researchers quickly locate resources that would not otherwise be on their radar.

During this process, researchers will likely identify other researchers writing on aspects of their topic. Researchers should consider searching for the publications of these relevant researchers (see table 3 for search strategies). Additionally, institutional websites may include curriculum vitae of such relevant faculty with access to their entire publication record, including difficult to locate publications, such as book chapters, dissertations, and technical reports.

Strategies for Finding Related Researcher Publications in Databases and Search Engines

An external file that holds a picture, illustration, etc.
Object name is i1949-8357-8-3-297-t03.jpg

Search Tools and Related Literature

Researchers will locate the majority of needed information using databases and search engines. Excellent resources are available to guide researchers in the mechanics of literature searches. 15 , 16

Because medical education research draws on a variety of disciplines, researchers should include search tools with coverage beyond medicine (eg, psychology, nursing, education, and anthropology) and that cover several publication types, such as reports, standards, conference abstracts, and book chapters (see the box for several information resources). Many search tools include options for viewing citations of selected articles. Examining cited references provides additional articles for review and a sense of the influence of the selected article on its field.

Box Information Resources

Education Resource Information Center (ERIC)
Cumulative Index of Nursing & Allied Health (CINAHL) a
Google Scholar

Once relevant articles are located, it is useful to mine those articles for additional citations. One strategy is to examine references of key articles, especially review articles, for relevant citations.

Getting Organized

As the aforementioned resources will likely provide a tremendous amount of information, organization is crucial. Researchers should determine which details are most important to their study (eg, participants, setting, methods, and outcomes) and generate a strategy for keeping those details organized and accessible. Increasingly, researchers utilize digital tools, such as Evernote, to capture such information, which enables accessibility across digital workspaces and search capabilities. Use of citation managers can also be helpful as they store citations and, in some cases, can generate bibliographies ( table 4 ).

Knowing When to Say When

Researchers often ask how to know when they have located enough citations. Unfortunately, there is no magic or ideal number of citations to collect. One strategy for checking coverage of the literature is to inspect references of relevant articles. As researchers review references they will start noticing a repetition of the same articles with few new articles appearing. This can indicate that the researcher has covered the literature base on a particular topic.

Putting It All Together

In preparing to write a research paper, it is important to consider which citations to include and how they will inform the introduction and discussion sections. The “Instructions to Authors” for the targeted journal will often provide guidance on structuring the literature review (or introduction) and the number of total citations permitted for each article category. Reviewing articles of similar type published in the targeted journal can also provide guidance regarding structure and average lengths of the introduction and discussion sections.

When selecting references for the introduction consider those that illustrate core background theoretical and methodological concepts, as well as recent relevant studies. The introduction should be brief and present references not as a laundry list or narrative of available literature, but rather as a synthesized summary to provide context for the current study and to identify the gap in the literature that the study intends to fill. For the discussion, citations should be thoughtfully selected to compare and contrast the present study's findings with the current literature and to indicate how the present study moves the field forward.

To facilitate writing a literature review, journals are increasingly providing helpful features to guide authors. For example, the resources available through JGME include several articles on writing. 17 The journal Perspectives on Medical Education recently launched “The Writer's Craft,” which is intended to help medical educators improve their writing. Additionally, many institutions have writing centers that provide web-based materials on writing a literature review, and some even have writing coaches.

The literature review is a vital part of medical education research and should occur throughout the research process to help researchers design a strong study and effectively communicate study results and importance. To achieve these goals, researchers are advised to plan and execute the literature review carefully. The guidance in this editorial provides considerations and recommendations that may improve the quality of literature reviews.

Writing a literature review

Find out how to write a lit review.

What is a literature review ?

A literature review explores and evaluates the literature on a specific topic or question. It synthesises the contributions of the different authors, often to identify areas that need further exploration.

You may be required to write a literature review as a standalone document or part of a larger body of research, such as a thesis.

The point of a standalone literature review is to demonstrate that you have read widely in your field and you understand the main arguments.
As part of a thesis or research paper, the literature review defines your project by establishing how your work will extend or differ from previous work and what contribution it will make.

What are markers looking for?

In the best literature reviews, the writer:

Has a clear understanding of key concepts within the topic.
Clarifies important definitions and terminology.
Covers the breadth of the specific topic.
Critically discusses the ideas in the literature and evaluates how authors present them.
Clearly indicates a research gap for future enquiry.

How do I write a literature review?

This video outlines a step by step approach to help you evaluate readings, organise ideas and write critically. It provides examples of how to connect, interpret and critique ideas to make sure your voice comes through strongly.

Tips for research, reading and writing

You may be given a specific question to research or broad topics which must be refined to a question that can be reasonably addressed in the time and word limit available.

Use your early reading to help you determine and refine your topic.

Too much literature? You probably need to narrow your scope. Try to identify a more specific issue of interest.
Not enough literature? Your topic may be too specific and needs to be broader.

Start with readings suggested by your lecturers or supervisors. Then, do your own research - the best place to go is the Library Website .

You can also use the Library Guides or speak to a librarian to identify the most useful databases for you and to learn how to search for sources effectively and efficiently.

Cover the field

Make sure your literature search covers a broad range of views and information relevant to your topic. Focussing on a narrow selection of sources may result in a lack of depth. You are not expected to cover all research and scholarly opinions on your topic, but you need to identify and include important viewpoints. A quality literature review examines and evaluates different viewpoints based on the evidence presented, rather than providing only material that reinforces a bias.

Use reading strategies

Survey, skim and scan to find the most relevant articles, and the most relevant parts of those articles. These can be re-read more closely later when you have acquired an overview of your topic.

Take notes as you read

This helps to organise and develop your thoughts. Record your own reactions to the text in your notes, perhaps in a separate column. These notes can form the basis of your critical evaluation of the text. Record any facts, opinions or direct quotes that are likely to be useful to your review, noting the page numbers, author and year.

Stop reading when you have enough

This depends on the word count required of this literature review. A review of one thousand words can only cover the major ideas and probably less than ten references. Longer reviews that form part of a large research paper will include more than fifty. Your tutor or supervisor should be able to suggest a suitable number.

As you read, ask yourself these questions:

Have I answered my question without any obvious gaps?
Have I read this before? Are there any new related issues coming up as I search the literature?
Have I found multiple references which cover the same material or just enough to prove agreement?

There are many possible ways to organise the material. For example:

chronologically
by theoretical perspective
from most to least important
by issue or theme

It is important to remember that you are not merely cataloguing or describing the literature you read. Therefore, you need to choose an organisation that will enable you to compare the various authors' treatment of ideas. This is often best achieved by organising thematically, or grouping ideas into sets of common issues tackled in the various texts. These themes will form the basis of the different threads that are the focus of your study.

A standalone literature review

A standalone literature review is structured much like an academic essay.

Introduction - establish the context for your topic and outline your main contentions about the literature
Main body - explain and support these inferences in the main body
Conclusion - summarise your main points and restate the contention.

The main difference between an essay and this kind of literature review is that an essay focuses on a topic and uses the literature as a support for the arguments. In a standalone literature review, the literature itself is the topic of discussion and evaluation. This means you evaluate and discuss not only the informational content but the quality of the author’s handling of the content.

A literature review as part of a larger research paper?

As part of a larger research paper, the literature review may take many forms, depending on your discipline, your topic and the logic of your research. Traditionally, in empirical research, the literature review is included in the introduction, or a standalone chapter immediately following the introduction. For other forms of research, you may need to engage more extensively with the literature and thus, the literature review may spread over more than one chapter, or even be distributed throughout the thesis.

Start writing early. Writing will clarify your thinking on the topic and reveal any gaps in information and logic. If your ideas change, sections and paragraphs can be reworked to change your contentions or include extra information.

Similarly, draft an overall plan for your review as soon as you are ready, but be prepared to rework sections of it to reflect your developing argument.

The most important thing to remember is that you are writing a review . That means you must move past describing what other authors have written by connecting, interpreting and critiquing their ideas and presenting your own analysis and interpretation.

While there might be many reasons for conducting a literature review, following are four key outcomes of doing the review.

Assessment of the current state of research on a topic . This is probably the most obvious value of the literature review. Once a researcher has determined an area to work with for a research project, a search of relevant information sources will help determine what is already known about the topic and how extensively the topic has already been researched.

Identification of the experts on a particular topic . One of the additional benefits derived from doing the literature review is that it will quickly reveal which researchers have written the most on a particular topic and are, therefore, probably the experts on the topic. Someone who has written twenty articles on a topic or on related topics is more than likely more knowledgeable than someone who has written a single article. This same writer will likely turn up as a reference in most of the other articles written on the same topic. From the number of articles written by the author and the number of times the writer has been cited by other authors, a researcher will be able to assume that the particular author is an expert in the area and, thus, a key resource for consultation in the current research to be undertaken.

Identification of key questions about a topic that need further research . In many cases a researcher may discover new angles that need further exploration by reviewing what has already been written on a topic. For example, research may suggest that listening to music while studying might lead to better retention of ideas, but the research might not have assessed whether a particular style of music is more beneficial than another. A researcher who is interested in pursuing this topic would then do well to follow up existing studies with a new study, based on previous research, that tries to identify which styles of music are most beneficial to retention.

Determination of methodologies used in past studies of the same or similar topics. It is often useful to review the types of studies that previous researchers have launched as a means of determining what approaches might be of most benefit in further developing a topic. By the same token, a review of previously conducted studies might lend itself to researchers determining a new angle for approaching research.

Upon completion of the literature review, a researcher should have a solid foundation of knowledge in the area and a good feel for the direction any new research should take. Should any additional questions arise during the course of the research, the researcher will know which experts to consult in order to quickly clear up those questions.

The Importance and Role of Biostatistics in Clinical Research

“A substantive, thorough, sophisticated literature review is a precondition for doing substantive, thorough, sophisticated research”. Boote and Baile 2005

Authors of manuscripts treat writing a literature review as a routine work or a mere formality. But a seasoned one knows the purpose and importance of a well-written literature review. Since it is one of the basic needs for researches at any level, they have to be done vigilantly. Only then the reader will know that the basics of research have not been neglected.

Importance of Literature Review In Research

The aim of any literature review is to summarize and synthesize the arguments and ideas of existing knowledge in a particular field without adding any new contributions. Being built on existing knowledge they help the researcher to even turn the wheels of the topic of research. It is possible only with profound knowledge of what is wrong in the existing findings in detail to overpower them. For other researches, the literature review gives the direction to be headed for its success.

The common perception of literature review and reality:

As per the common belief, literature reviews are only a summary of the sources related to the research. And many authors of scientific manuscripts believe that they are only surveys of what are the researches are done on the chosen topic. But on the contrary, it uses published information from pertinent and relevant sources like

Scholarly books
Scientific papers
Latest studies in the field
Established school of thoughts
Relevant articles from renowned scientific journals

and many more for a field of study or theory or a particular problem to do the following:

Summarize into a brief account of all information
Synthesize the information by restructuring and reorganizing
Critical evaluation of a concept or a school of thought or ideas
Familiarize the authors to the extent of knowledge in the particular field
Encapsulate
Compare & contrast

By doing the above on the relevant information, it provides the reader of the scientific manuscript with the following for a better understanding of it:

It establishes the authors’ in-depth understanding and knowledge of their field subject
It gives the background of the research
Portrays the scientific manuscript plan of examining the research result
Illuminates on how the knowledge has changed within the field
Highlights what has already been done in a particular field
Information of the generally accepted facts, emerging and current state of the topic of research
Identifies the research gap that is still unexplored or under-researched fields
Demonstrates how the research fits within a larger field of study
Provides an overview of the sources explored during the research of a particular topic

Importance of literature review in research:

The importance of literature review in scientific manuscripts can be condensed into an analytical feature to enable the multifold reach of its significance. It adds value to the legitimacy of the research in many ways:

Provides the interpretation of existing literature in light of updated developments in the field to help in establishing the consistency in knowledge and relevancy of existing materials
It helps in calculating the impact of the latest information in the field by mapping their progress of knowledge.
It brings out the dialects of contradictions between various thoughts within the field to establish facts
The research gaps scrutinized initially are further explored to establish the latest facts of theories to add value to the field
Indicates the current research place in the schema of a particular field
Provides information for relevancy and coherency to check the research
Apart from elucidating the continuance of knowledge, it also points out areas that require further investigation and thus aid as a starting point of any future research
Justifies the research and sets up the research question
Sets up a theoretical framework comprising the concepts and theories of the research upon which its success can be judged
Helps to adopt a more appropriate methodology for the research by examining the strengths and weaknesses of existing research in the same field
Increases the significance of the results by comparing it with the existing literature
Provides a point of reference by writing the findings in the scientific manuscript
Helps to get the due credit from the audience for having done the fact-finding and fact-checking mission in the scientific manuscripts
The more the reference of relevant sources of it could increase more of its trustworthiness with the readers
Helps to prevent plagiarism by tailoring and uniquely tweaking the scientific manuscript not to repeat other’s original idea
By preventing plagiarism , it saves the scientific manuscript from rejection and thus also saves a lot of time and money
Helps to evaluate, condense and synthesize gist in the author’s own words to sharpen the research focus
Helps to compare and contrast to show the originality and uniqueness of the research than that of the existing other researches
Rationalizes the need for conducting the particular research in a specified field
Helps to collect data accurately for allowing any new methodology of research than the existing ones
Enables the readers of the manuscript to answer the following questions of its readers for its better chances for publication
What do the researchers know?
What do they not know?
Is the scientific manuscript reliable and trustworthy?
What are the knowledge gaps of the researcher?

22. It helps the readers to identify the following for further reading of the scientific manuscript:

What has been already established, discredited and accepted in the particular field of research
Areas of controversy and conflicts among different schools of thought
Unsolved problems and issues in the connected field of research
The emerging trends and approaches
How the research extends, builds upon and leaves behind from the previous research

A profound literature review with many relevant sources of reference will enhance the chances of the scientific manuscript publication in renowned and reputed scientific journals .

Database search tip : Add the phrase "literature review" to your search to find published literature reviews.

While at the GSD, you may be asked to conduct a literature review for research courses or if you are writing a thesis or dissertation.

What is a literature review?

It is a survey of relevant or foundational texts about a particular topic, theory, or research question. A literature review

May provide the background for larger work, or it may stand on its own.

Is more than a simple list of sources; an effective literature review analyzes and synthesizes information about key themes or issues.

Contains a set of themes fundamental enough to be considered a reasonable mode of entry into the field along with the relevant, foundational texts of that field or sub-field.

Coheres around a chronological, geographic, technical, and/or cultural structure.

Is thorough but not comprehensive; it is impossible to reach an exhaustive knowledge of a field, especially as a graduate student.

How do you conduct a literature review?

Gather Sources through preliminary research

This step allows you to discover what has been written about in the field
Focus your topic: A literature review aims to cover all of the research on a given topic. If the topic is too large, there will be too much material to cover it adequately.

The GSD’s guidelines for doctoral literature reviews offers helpful examples of feasible topics:

A research area usually covers a relatively broad field like the ‘history of architecture from 1800 to the present,’ the ‘theories of urbanization in the nineteenth and twentieth centuries,’ or ‘digital fabrication.’ More focused major fields are of course possible and could include studies of ‘Decorative Art, Design and the Object: History, Theory, and Debate: 1850-1930,’ ‘Modernity and Modernism in Latin America,’ or ‘Life Cycle Design.’

Read with a purpose: Although you will need to briefly summarize sources, a good literature review requires that you isolate key themes or issues related to your own research interests.

Evaluate Sources

Conduct a critical appraisal to evaluate the literature and what has been done already to see the gaps in the field, thus what still needs to be done in one’s own research

For each book or article consider: Is the author an expert? Does the evidence support the conclusion? Is the argument or evidence complete?

Does all research arrive at the same conclusion or are there differing opinions? What evidence or reasoning are the differences based on? What questions are raised by the literature? Are there any gaps or omissions?

Write an Introduction

The introduction should identify your topic, some discussion of the significance of that topic and a thesis statement that outlines what conclusion you will draw from your analysis and synthesis of the literature. If your literature review is part of a larger work, explain the importance of the review to your research question.
Focus on the organizing principles of your literature review. How have you organized your sources?

Have you organized it by theme? This is the most common way to organize literature reviews as it relates each source back to the field.

Have you organized it by methodology? This is often used when discussing interdisciplinary approaches to a topic or when discussing a number of studies with a different approach.

Have you organized it by chronology? This method is helpful when historical changes are central to explaining the topic.

Write the body

The body will be comprised of your findings from evaluating the sources. In the body, discuss and assess the research according to the specific organizational principles above.
Focus on the relationship of sources to each other: how do these sources constitute a field?
Return to your evaluations and critical appraisals of the texts. Include these appraisals in the body of your literature review.
Articulate the relevance of these sources to your research question.
Demonstrate that your research and source selection is sufficient to constitute a reasonable mode of entry into the particular field where you what to conduct subsequent research.

Write the conclusion

This section is perhaps the most important: you should briefly outline all gaps in the field and assess what is lacking in the current field of literature. Thus, you establish the value of your research and where you will situate your research within the context that you have explored in the body.

Metrics details

The number of older people in prison is growing. As a result, there will also be more prisoners suffering from dementia. The support and management of this population is likely to present multiple challenges to the prison system.

To examine the published literature on the care and supervision of people living in prison with dementia and on transitioning into the community; to identify good practice and recommendations that might inform the development of prison dementia care pathways.

A scoping review methodology was adopted with reporting guided by the PRISMA extension for scoping reviews checklist and explanation.

Sixty-seven papers were included. Most of these were from high income countries, with the majority from the United Kingdom ( n = 34), followed by the United States ( n = 15), and Australia ( n = 12). One further paper was from India.

The literature indicated that there were difficulties across the prison system for people with dementia along the pathway from reception to release and resettlement. These touched upon all aspects of prison life and its environment, including health and social care. A lack of resources and national and regional policies were identified as important barriers, although a number of solutions were also identified in the literature, including the development of locally tailored policies and increased collaboration with the voluntary sector.

To our knowledge, this is the most comprehensive and inclusive review of the literature on dementia care pathways in prison to date. It has identified a number of important areas of concern and opportunities for future research across the prison system, and its operations. This will hopefully lead to the identification or adaptation of interventions to be implemented and evaluated, and facilitate the development of dementia care pathways in prisons.

The number of older people (defined here as those over 50 Footnote 1 ) being held in prison in England and Wales has almost tripled over the last 20 years, and they now represent 17.1% of that population (Ministry of Justice, 2022a ). The growing number of older people has brought with it an increasing number of health and social care problems, reportedly affecting around 85% of older people in prison, with associated costs (Di Lorito, et al., 2018 ; Hayes et al., 2012 , 2013 ; Senior, et al., 2013 ). It has been estimated that 8.1% of those over the age of 50 in prison have mild cognitive impairment or dementia, which is much higher than estimates for this age group in the general population (Dunne et al., 2021 ; Forsyth et al., 2020 ). This pattern of poor health also increased the vulnerability of older people in prison during the pandemic (Kay, 2020 ).

Prison policy and legislation mandates that health and social care be ‘equivalent’ to that provided in the community (Care Act, 2014 ; Department of Health, 1999 ). Despite this, provisions are reportedly inconsistent, and the government has been described as ‘failing’ in its duty of care (Health and Social Care Committee, 2018 ; HM Inspectorate of Prisons & Care Quality Commission, 2018 ). This is likely exacerbated by the suspension and limiting of healthcare services during the pandemic, noted to have had a ‘profound’ impact on people’s health and wellbeing (HM Inspectorate of Prisons, 2021 ). This may be particularly so for people living in prison with dementia (PLiPWD), whereby the difficulties of delivering health and social care are compounded by inappropriate buildings, environments, and prison regimes (rules and regulations). In addition, PLiPWDs may experience an increase in social isolation, including separation from friends and family, all of which may make their time in prison more challenging (Moll, 2013 ; Peacock et al., 2019 ).

There is no current national strategy for older people in prison in England and Wales, including PLiPWD, although the British government recently agreed that there is a need for one (Justice Committee, 2020 ). A ‘Model for Operational Delivery’ for older people has been published by Her Majesty's Prison & Probation Service ( 2018 ) in England and Wales, though this is guidance only and the “properly resourced and coordinated strategy” previously called for has not been produced (Prisons & Probation Ombudsman, 2017 , p7; Brooke and Rybacka, 2020 ; HM Inspectorate of Prisons, 2019 ; Justice Committee, 2020 ). One way of attempting to standardise and improve the quality of treatment and care in the community has been through the use of care pathways (Centre for Policy on Ageing, 2014 ; Schrijvers et al., 2012 ). Care pathways have been defined as “a complex intervention for the mutual decision-making and organisation of care processes for a well-defined group of patients during a well-defined period”, involving an articulation of goals and key aspects of evidence-based care, coordination and sequencing of activities and outcomes evaluation (Vanhaecht, et al., 2007 , p137).

The development of care pathways within the prison system lags behind that of the community, but the National Institute for Health and Care Excellence (NICE) has produced a pathway for prisoner health for England and Wales (National Institute for Health and Care Excellence, 2019 ), and there is a care pathway for older prisoners in Wales (Welsh Government & Ministry of Justice, 2011 ). There has also recently been an overall care pathway developed for people in prison with mild cognitive impairment and dementia, although this has not been implemented as yet, and it does not include any details regarding release and resettlement (Forsyth et al, 2020 ). It has been recommended that care pathways should be developed locally, as they are context-sensitive, should be viewed as processual and flexible, and the needs of the person, their experiences and characteristics need to be taken into account – such as age, gender and race (Centre for Policy on Ageing, 2014 ; Pinder, et al., 2005 ).

Here we review the current literature on people living in prison with dementia. There have been two recent systematic literature reviews conducted on PLiPWD, both of which only included primary research studies that were small in number (Brooke and Rybacka, 2020 ( n = 10); Peacock et al., 2019 ( n = 8)), and focused on prevalence, identification (screening and diagnosis), and the need for tailored programming and staff training. Peacock et al., ( 2019 ) identified dementia as a concern and suggested recommendations for improved screening and care practices. Brooke et al. ( 2020 ) noted that, whilst the prevalence of dementia in prison populations was largely unknown, there was a need for national policies and local strategies that support a multi-disciplinary approach to early detection, screening and diagnosis. Neither paper, however, reported on the much more extensive and rich grey literature in this area (Brooke and Rybacka, 2020 ), to help comprehensively identify the systemic and operational problems, barriers and potential solutions that would be useful to consider in developing local dementia care pathways. Therefore, the aim of this paper is to conduct a comprehensive systematic scoping review of the available published literature on the support and management of PLiPWD in prison and upon transitioning into the community, and to identify practice and recommendations that would be useful to consider in the development of a local prison dementia care pathway.

A scoping review methodology using Arksey and O’Malley’s ( 2005 ) five-stage framework was adopted for this review. Reporting was guided by the PRISMA extension for scoping reviews checklist and explanation (Tricco et al., 2018 ). The completed checklist for this review is available in Additional file 1 : Appendix 1.

Identification of relevant reports

The search strategy was formulated by the research team, and included an electronic database search and subsequent hand search. The electronic search involved searching twelve electronic databases: Applied Social Sciences Index and Abstract, Criminal Justice Abstracts, Embase, Medline (OVID), National Criminal Justice Reference Service, Open Grey, Psycinfo, Pubmed, Scopus, Social Services Abstracts, Sociological Abstracts, and Web of Science. The search combined condition-related terms (dementia OR Alzheimer*) AND context-related ones (prison OR jail OR gaol OR penitentia* OR penal OR correctional* OR incarcerat*), with no date or language restrictions, and covered the full range of publications up until April 2022. Additional file 2 : Appendix 2 has an example of the search strategy used.

Electronic searches were supplemented by comprehensive hand searching and reference mining. Searches were also undertaken using: search engines; websites related to prisons and/or dementia (for example, Prison Reform Trust); a database from a previous related literature review (Lee et al, 2019 ); recommendations from academic networking sites; contacting prominent authors in the field directly; government-related websites (for example Public Health England, now called Health Security Agency); recent inspection reports for all prisons in England and Wales from Her Majesty’s Inspectorate of Prisons and the Independent Monitoring Board.

Inclusion and exclusion criteria

Papers were considered suitable for inclusion in this review if they met the following criteria:

Setting: Papers should primarily be set in, or pertain to, prisons. Documents solely referring to community services, hospitals or medical facilities that are not part of the prison system were excluded.

People: Papers involving PLiPWD. Research focused only on older people in prison more generally was excluded, as was research which described the disorienting effects of imprisonment more generally, but which was not related to dementia.

Intervention: Some consideration of the treatment, care, support or management of PLiPWD; this can be health or social-care associated, as well as related to the prison overall, and to any individuals, groups or agencies who visit or work with individuals during their time in prison (including family, friends, charities, probation services). Papers which mostly describe prevalence studies, sentencing practices or profiles were excluded.

Study design: All designs were considered for inclusion. Editorials, book reviews, online blogs, press releases, announcements, summaries, newspaper and magazine articles, abstracts and letters were excluded.

The titles, abstracts and full-text of the papers identified by the searches were screened for inclusion in the review. The screening was undertaken by two independent researchers (ST and NS) for inter-rater reliability purposes (Rutter et al., 2010 ). Any differences of opinion on inclusion were resolved between the researchers (ST, NS and SM), and with the Principle Investigator (TVB).

Charting the data

An extraction template was developed for the review, guided by the PICO formula (Richardson et al., 1995 ) and informed by pathway stages and key areas highlighted in the older prisoner pathways toolkit for England and Wales (Department of Health, 2007 ), and the older prisoner pathway formulated for Wales (Welsh Government & Ministry of Justice, 2011 ). Using this extraction template, all of the data was extracted from the included papers by one member of the research team (ST), with a second researcher extracting data from a third of the papers as a check for consistency (SM). Any unresolved issues were related to the Principle Investigator (TVB) for resolution.

Collating, summarising and reporting results

The review was deliberately inclusive of a wide variety of types of papers, which meant that taking a meta-analytic approach to the data was not feasible. Therefore, a narrative approach to summarising and synthesising the findings and recommendations of the included papers was adopted (Popay et al, 2006 ).

Sixty-seven papers were included in this scoping review. The screening process phases conducted by the research team are shown in Fig. 1 .

PRISMA flow diagram

A brief overview of the key features of each of the papers is presented in Table 1 . All but one of the included papers were from high income countries, with the majority from the United Kingdom ( n = 34), and then the United States ( n = 15), Australia ( n = 12), Canada ( n = 4), Italy ( n = 1) and India ( n = 1). The papers were split into types, with twenty-two guidance and inspection documents, and twenty-seven discussion and intervention description papers. Of the eighteen research and review articles with a defined methodology included there were four literature reviews (one was systematic), nine qualitative studies, four mixed-methods studies (one which followed participants up), and one survey-based study.

Areas to consider in the support and management of PLiPWD during their time in prison and upon their release

The pathway through the prison is shown in Fig. 2 , and typically involves: (i) reception into prison; (ii) assessments, and allocation of the person within prison; (iii) time held in prison; (iv) transfers between prisons, and between prisons and other services such as time spent in hospital; and (v) release and preparations for resettlement in the community. There were also a number of (vi) cross-cutting themes which could potentially impact people with dementia living in prison at each stage across the prison pathway.

Dementia prison pathway considerations

(i) Reception

Upon entry into prison, prisoners are subject to an initial reception screening to identify and support immediate health and social care problems, and those in need of further assessment. An induction to prison rules and regulations also typically occurs at this step.

All papers reported that reception screening with appropriate screening tools was important in identifying cognitive difficulties and in establishing a baseline, but implementation seemed to vary (Peacock et al., 2019 ). One study in England and Wales found only 30% of prisons contacted routinely did this (Forsyth et al., 2020 ). Supporting policy and a service/person to refer to directly for further assessment were also highlighted as useful (Brooke & Jackson, 2019 ; Brooke et al., 2018 ; Gaston & Axford, 2018 ; Inspector of Custodial Services, 2015 ; Patterson et al., 2016 ). Proposed cut-offs for this screening were either 50 years of age ( n = 7), under 55 years ( n = 1), or 55 years of age ( n = 7). One paper reported that only a third of prisoners who were offered this screening accepted it, although the reasons for this were not stated (Patel & Bonner, 2016 ). Another paper suggested that a screening programme could have unintended adverse consequences, that could damage already fragile relationships between staff and people living in prison (Moore & Burtonwood, 2019 ). Whilst many screening tools were mentioned, there are currently no tools validated for use in prisons, and many of those used in the community may be inappropriate (Baldwin & Leete, 2012 ; Brooke et al., 2018 ; du Toit et al., 2019 ; Feczko, 2014 ; Forsyth et al., 2020 ; Moore & Burtonwood, 2019 ; National Institute for Health and Care Excellence, 2017 ; Turner, 2018 ; Williams et al., 2012 ). One validation study found that the Six-item Cognitive Impairment Test (6CIT) was not suitably sensitive for use (Forsyth et al., 2020 ). Other difficulties included the limited amount of time and resources available to screen at reception (Christodoulou, 2012 ; Patterson et al., 2016 ; Peacock et al., 2019 ), and that staff lacked ‘familiarity’ with screening tools (Peacock et al., 2019 ).

Only two papers mentioned the induction process (Her Majesty's Prison & Probation Service, 2018 ; Welsh Government and Ministry of Justice, 2011 ) as important. A need for clearly explained information in a dementia-appropriate format (written and verbal) particularly regarding healthcare, and a recommendation that PLiPWD should be regularly reminded of rules and regulations, were suggested.

(ii) Assessment

Following the screening process, the current recommendation is that an initial healthcare assessment takes place in the first seven days after entering prison. During this initial assessment period, although not necessarily within this timeframe, care plans and allocation decisions may also be made regarding where the prisoner is placed within the prison.

An initial older-person-specific health and/or social care assessment or standard process for assessment has been recommended by ten papers, six of which were from government or related bodies. It was also suggested by some papers, that a cognitive assessment should take place at either 50 years ( n = 6) or 55 years ( n = 2), which should be repeated every three months ( n = 3), six months ( n = 5) or annually ( n = 12), with the latter including recommendations from NICE guidelines (National Institute for Health and Care Excellence, 2017 ). One study set in England and Wales found that most prisons (60%) that screened older people, did so between 7–12 months (Forsyth et al., 2020 ). Brief and affordable tools were considered more useful (Garavito, 2020 ; Turner, 2018 ), although the Montreal Cognitive Assessment (MOCA) was recommended in the care pathway developed by Forsyth et al. ( 2020 ).

Typically, assessments were conducted by healthcare staff, GPs or a psychologist ( n = 6), a specialist in-house assessment unit ( n = 2), or a specific dementia admissions assessment unit ( n = 4). For further assessment, some prisons had internal teams to refer to ( n = 5). Forsyth et al. ( 2020 ) recommend referral to external Memory Assessment Services for assessment. A case finding tool was being piloted in one prison (Sindano & Swapp, 2019 ). Assessments included can be found in Table 2 .

Assessments also explored risk and safeguarding (National Institute for Health and Care Excellence, 2017 ; Patterson et al., 2016 ; Welsh Government and Ministry of Justice, 2011 ), environmental impact (National Institute for Health and Care Excellence, 2017 ), capacity (Prison & Probation Ombudsman, 2016 ), work, education, and drug and alcohol use (Welsh Government and Ministry of Justice, 2011 ) and a person’s strengths (Hamada, 2015 ; National Institute for Health and Care Excellence, 2017 ). Prison staff contributed to some assessments of activities of daily living (ADLs) or prison-modified ADLs (Brooke et al., 2018 ; Brown, 2016 ; Dillon et al., 2019 ; Department of Health, 2007 ; Feczko, 2014 ; Forsyth et al., 2020 ; Gaston, 2018 ; Gaston & Axford, 2018 ; Patterson et al., 2016 ; Turner, 2018 ; Welsh Government and Ministry of Justice, 2011 ; Williams et al., 2012 ). Challenges to Assessment can be found in Table 3 .

Twelve papers described or recommended care planning post-assessment, in collaboration with PLiPWD and primary care, or a multi-disciplinary team (MDT) of health, social care and prison staff with external specialists healthcare proxies charities or family (Brown, 2016 ; Dillon et al., 2019 ; du Toit & Ng, 2022 ; Hamada, 2015 ; Her Majesty's Inspectorate of Prisons, 2014 ; Her Majesty's Prison & Probation Service, 2018 ; Moll, 2013 ; National Institute for Health and Care Excellence, 2017 ; Patterson et al., 2016 ; Prisons and Probation Ombudsman, 2016 ; Welsh Government and Ministry of Justice, 2011 ). However, it was suggested that prison staff be removed from the decision-making process as the dementia progresses, and be part of the ‘duty of care’ of healthcare staff and services (du Toit & Ng, 2022 ). It was recommended too that care plans be disseminated to prison wing staff (Forsyth et al., 2020 ) and peer supporters (Goulding, 2013 ), and that consent be sought for this (Goulding, 2013 ; Her Majesty's Inspectorate of Prisons, 2014 ) An ombudsman report in England and Wales noted that care plans for PLiPWD who had died in prison were inadequate (Peacock et al., 2018 ), and of the varying degrees of care planning found by Forsyth et al ( 2020 ), it was described typically as “rudimentary” (p26). Care plans are described further in Table 4 .

Many papers reported that prisons did or should make decisions about where people should be accommodated within the prison after health assessments (Brown, 2016 ; Feczko, 2014 ; Forsyth et al., 2020 ; Hodel & Sanchez, 2013 ; Inspector of Custodial Services, 2015 ; Mistry & Muhammad, 2015 ; Turner, 2018 ; Welsh Government and Ministry of Justice, 2011 ; Williams et al., 2012 ), taking age and health into account. However, despite recommendations that PLiPWD should be placed on the ground floor on low bunks for instance (Baldwin & Leete, 2012 ; Department of Health, 2007 ; Welsh Government and Ministry of Justice, 2011 ), there were reports that this was not happening (Inspector of Custodial Services, 2015 ). There were also recommendations for allocations to be made across a region to ensure people are appropriately placed in the prison system (Baldwin & Leete, 2012 ; Booth, 2016 ; Gaston & Axford, 2018 ; Welsh Government and Ministry of Justice, 2011 ). Concerns were expressed about the lack of lower category places for PLiPWD (Department of Health, 2007 ), and the lack of guidance regarding placement of people with high support needs (Sindano & Swapp, 2019 ) in England and Wales.

(iii) Within-prison issues

A number of papers reported on a need for policies or frameworks to support staff to identify, assess and support people who may be living with dementia (Brooke et al., 2018 ; Brooke & Jackson, 2019 ; Department of Health, 2007 ; Feczko, 2014 ; Gaston, 2018 ; Gaston & Axford, 2018 ; Patterson et al., 2016 ; Turner, 2018 ; Welsh Government and Ministry of Justice, 2011 ), without which staff have faced difficulties in providing quality care and support (Feczko, 2014 ; Prisons and Probation Ombudsman, 2016 ). Whilst there were some examples of guidance for dementia (Hamada, 2015 ; Patterson et al., 2016 ; Treacy et al., 2019 ; Turner, 2018 ), it was suggested that all policies should be reviewed and amended to ensure that they are appropriate for older people and people living with dementia (Department of Health, 2007 ; Lee et al., 2019 ; Treacy et al., 2019 ). Specific policy areas are described in Table 5 .

Issues around staff training on dementia were discussed in the majority of papers ( n = 54) Many of these reported that prison staff either lacked training on dementia, or that training was limited ( n = 16), with one study in England and Wales reporting that only a quarter of prison staff had received such training (Forsyth et al., 2020 ). Perhaps consequently, a number of papers identified that prison staff required some dementia training ( n = 19). Staff working on a specialist dementia unit reportedly had a comprehensive 40-h training (Brown, 2014 , 2016 ; Gaston & Axford, 2018 ; Hodel & Sanchez, 2013 ; Moll, 2013 ), and it was suggested that more comprehensive training be facilitated for officers, particularly those working with PLiPWD ( n = 18) and offender managers ( n = 2). A need for all staff working with PLiPWD to be supervised was also suggested (Gaston & Axford, 2018 ; Maschi et al., 2012 ). Despite a lack of consensus on content and duration (du Toit et al, 2019 ), typically, the staff training undertaken and recommended was in four areas (Table 6 ). It was also recommended that training for healthcare could be more comprehensive and focused on screening, identification, assessment, diagnoses, supervision and intervention training (Baldwin & Leete, 2012 ; Brooke & Jackson, 2019 ; Brown, 2014 ; Gaston & Axford, 2018 ; Her Majesty's Inspectorate of Prisons, 2014 ; Moll, 2013 ; Moore & Burtonwood, 2019 ; National Institute for Health and Care Excellence, 2017 ; Peacock et al, 2019 ; Treacy et al, 2019 ; Turner, 2018 ; Williams, 2014 ). It is of note that only 21% of healthcare staff in one study in England and Wales reported attending training to identify dementia (Forsyth et al., 2020 ), similar to the figures regarding prison staff in the same study.

Much of the training described in the included papers had been formulated and delivered by dementia- or older people-specific voluntary organisations (Alzheimer’s Society, 2018 ; Brooke et al. 2018 ; Brown, 2016 ; Gaston & Axford, 2018 ; HMP Hull, 2015 ; Her Majesty's Prison & Probation Service, 2018 ; Hodel & Sanchez, 2013 ; Moll, 2013 ; Peacock et al., 2018 ; Prisons and Probation Ombudsman, 2016 ; Sindano & Swapp, 2019 ; Tilsed, 2019 ; Treacy et al., 2019 ). Although it has also been recommended to involve health and social care (Goulding, 2013 ; Her Majesty's Prison & Probation Service, 2018 ; Ministry of Justice, 2013 ; Treacy et al., 2019 ; Turner, 2018 ), and officers and peer supporters (Brooke & Jackson, 2019 ; Masters et al., 2016 ; National Institute for Health and Care Excellence, 2017 ; Treacy et al., 2019 ) in developing the training. In one study, prison staff were also trained to deliver dementia information sessions to their peers (Treacy et al., 2019 ). A suggestion of video-training packages was also made (du Toit et al., 2019 ). Dementia training typically lacked robust evaluation (Brooke et al., 2018 ), although those available generally reported benefits in their understanding of dementia, relationships, and diagnoses (Goulding, 2013 ; HMP Littlehey, 2016 ; Masters et al., 2016 ; Sindano & Swapp, 2019 ; Treacy et al., 2019 ). It was also reported that some prison staff were resistant to working with PLiPWD (Moll, 2013 ), and that resource limitations resulted in training cuts (HMP Hull, 2015 ; Treacy et al., 2019 ).

Offering healthcare across the spectrum for PLiPWDs, from acute to chronic care, with a focus on preventative and long-term care as well as palliative care was recommended by some papers (Brown, 2014 ; du Toit & Ng, 2022 ; Gaston, 2018 ; Maschi et al., 2012 ; Mistry & Muhammad, 2015 ; Peacock et al, 2018 ; Welsh Government and Ministry of Justice, 2011 ; Williams et al., 2012 ). The development of care pathways to guide this were also recommended or formulated (du Toit et al., 2019 ; Forsyth et al., 2020 ; Peacock et al., 2019 ), although the majority (69%) of prisons in one study in England and Wales did not have one (Forsyth et al., 2020 ). Clear and formal links with local hospitals, memory clinics, forensic and community teams for planning, training, advice, support and in-reach were also present or recommended by sixteen research and guidance papers. The amount of healthcare cover in prisons in England and Wales reportedly varied with the function of the prison with largely only local prisons having 24-h healthcare staff (Treacy et al., 2019 ), and most other forms of prison having office-type hours’ healthcare cover – including sex offender prisons where the majority of older prisoners are held (Brown, 2016 ; Correctional Investigator Canada, 2019 ; Goulding, 2013 ; Inspector of Custodial Services, 2015 ; Treacy et al., 2019 ). While specialist services or units for PLiPWD exist in a number of jurisdictions (Baldwin & Leete, 2012 ; Brown, 2016 ; Cipriani et al., 2017 ; Gaston & Axford, 2018 ; Goulding, 2013 ; Hodel & Sanchez, 2013 ; Inspector of Custodial Services, 2015 ; Maschi et al., 2012 ; Mistry & Muhammad, 2015 ; Treacy et al, 2019 ), more are reportedly needed (Brooke et al., 2018 ; du Toit et al., 2019 ; Forsyth et al., 2020 ; Welsh Government and Ministry of Justice, 2011 ).

Most healthcare teams were reportedly MDT, or this was recommended, alongside joint health and social care working ( n = 16). A number of healthcare staff acted as the lead for older people in prisons (Department of Health, 2007 ; Her Majesty's Inspectorate of Prisons, 2014 ; Her Majesty's Inspectorate of Prisons, 2016 ; Moll, 2013 ; Welsh Government and Ministry of Justice, 2011 ), with a recommendation that a dementia-trained nurse should lead any dementia care pathways (Forsyth et al., 2020 ) and indeed it was suggested that healthcare staff in general have training and experience in working with older people (Her Majesty's Inspectorate of Prisons, 2014 ; Her Majesty's Inspectorate of Prisons, 2017b ; Moll, 2013 ; Patterson et al., 2016 ; Public Health England, 2017b ; Treacy et al., 2019 ; Turner, 2018 ; Welsh Government and Ministry of Justice, 2011 ). Whilst one of the recommended roles for healthcare was the prescription and monitoring of medication (Feczko, 2014 ; Her Majesty's Inspectorate of Prisons, 2017b ; Moll, 2013 ), much of the focus was on early identification and diagnosis, and keeping a dementia register (Department of Health, 2007 ; Moll, 2013 ; Patterson et al., 2016 ; Welsh Government and Ministry of Justice, 2011 ), and the use of non-pharmacological approaches. These broadly included: psychological interventions (Goulding, 2013 ; Hamada, 2015 ; Moll, 2013 ; Wilson & Barboza, 2010 ); assistance with ADLs and social care (Feczko, 2014 ; Hamada, 2015 ; Hodel & Sanchez, 2013 ; Maschi, et al., 2012 ; Murray, 2004 ; Prisons and Probation Ombudsman, 2016 ); development and delivery of specialist dementia prison programmes (Brown, 2014 , 2016 ; Hodel & Sanchez, 2013 ; Mistry & Muhammad, 2015 ; Moll, 2013 ; Peacock et al., 2018 ; Wilson & Barboza, 2010 ); reablement and rehabilitation (Welsh Government and Ministry of Justice, 2011 ); relaxation (Wilson & Barboza, 2010 ); safeguarding (Hodel & Sanchez, 2013 ); and cognitive stimulation groups (Moll, 2013 ; Williams, 2014 ). Other possible roles included: training or supporting staff and peer supporters, as reported in fourteen papers, as well as advocacy (Feczko, 2014 ; Peacock et al., 2018 ; Welsh Government and Ministry of Justice, 2011 ), allocation, assessment for offending behaviour groups, risk assessments and disciplinary hearings (Booth, 2016 ; Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ; Murray, 2004 ; Prisons and Probation Ombudsman, 2016 ). Challenges to Healthcare are noted in Table 7 .

Palliative care

A care pathway for dying people that meets community standards was recommended (Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ; Welsh Government and Ministry of Justice, 2011 ), as was ensuring that people could choose a preferred place to die (Her Majesty's Prison & Probation Service, 2018 ). Some prisoners were moved to community hospices or hospitals (Brooke & Jackson, 2019 ; Inspector of Custodial Services, 2015 ), or it was felt that they should be (Her Majesty's Prison & Probation Service, 2018 ). Although it was noted that some prisons lack relationships with community hospices or palliative care services and need to foster them (Brooke & Jackson, 2019 ; Brown, 2016 ; Correctional Investigator Canada, 2019 ; Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ).

A number of prisons also reportedly had hospices, particularly in the United States (Brooke et al., 2018 ; Brown, 2016 ; Feczko, 2014 ; Goulding, 2013 ; Williams et al., 2012 ), although these have not been comprehensively evaluated (Williams et al., 2012 ). It was recommended that these be staffed by MDTs (Her Majesty's Prison & Probation Service, 2018 ), including chaplains and nutritionists (Her Majesty's Prison & Probation Service, 2018 ; Goulding, 2013 ), and many included prisoner peer supporters (Brooke et al., 2018 ; Goulding, 2013 ). The use of independent contractors was also suggested as staff-prisoner relationships were considered problematic in some prisons (Williams et al., 2012 ). Regarding family, many hospices were described as allowing more visits (Brooke & Jackson, 2019 ; Goulding, 2013 ; Her Majesty's Prison & Probation Service, 2018 ), including one prison with family accommodation (Her Majesty's Prison & Probation Service, 2018 ). Whilst re-engaging with family was reportedly encouraged (Brown, 2016 ), a lack of support was noted (Correctional Investigator Canada, 2019 ). Suggested improvements include a family liaison officer, providing a list of counselling options, and hosting memorial services (Her Majesty's Prison & Probation Service, 2018 ).

Social care

A social care strategy for older prisoners and a social care lead for all prisons in England and Wales has been recommended (Department of Health, 2007 ; Prisons and Probation Ombudsman, 2016 ). It was reported that MDTs working with PLiPWD should and increasingly do include social workers including specialist units and hospices (Baldwin & Leete, 2012 ; Brooke et al., 2018 ; Brown, 2016 ; Cipriani et al., 2017 ; Goulding, 2013 ; HMP Littlehey, 2016 ; Her Majesty's Prison & Probation Service, 2018 ; Maschi et al., 2012 ; Prisons and Probation Ombudsman, 2016 ; Sindano & Swapp, 2019 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 ). Social care roles can be found in Table 8 .

The work may be direct or may be through co-ordinating external agencies or peer supporters (Brooke & Jackson, 2019 ; Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ; Prisons and Probation Ombudsman, 2016 ; Tilsed, 2019 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 ). Clarity in these roles was considered paramount, particularly as uncertainty reportedly continues to exist over who is responsible for meeting prisoners’ social care needs in some prisons in England and Wales despite the passing of the Care Act, 2014 (Dementia Action Alliance, 2017 ; Tilsed, 2019 ; Welsh Government and Ministry of Justice, 2011 ). There was also some ambiguity around the threshold PLiPWD were expected to meet in order to access social care (Forsyth et al., 2020 ). In some instances, personal care was delivered informally by untrained and unsupported prison staff and peer supporters in lieu of suitably trained social care workers (Treacy et al., 2019 ), with issues raised about the unavailability of social care through the night (Forsyth et al., 2020 ). Where social care staff were involved in coordinating personal care for prisoners, it was reported as positive for prisoners and prison staff (Her Majesty's Inspectorate of Prisons, 2016 ; Treacy et al., 2019 ), particularly, in one prison, where social care staff were prison-based (Forsyth et al., 2020 ).

Peer supporters

Prisoner peer supporters were operating in a number of prisons, as reported in 22 papers, and their employment was recommended by a further fourteen. Typically, these were people who had ‘good’ disciplinary and mental health records, and certainly in the US, were longer-serving prisoners. A number of papers indicated the need for peer supporters to receive training in dementia, including awareness and support (Brooke et al., 2018 ; Brooke & Jackson, 2019 ; Brown, 2016 ; Correctional Investigator Canada, 2019 ; Department of Health, 2007 ; Dillon et al., 2019 ; du Toit & Ng, 2022 ; Gaston, 2018 ; Gaston & Axford, 2018 ; Goulding, 2013 ; HMP Hull, 2015 ; HMP Littlehey, 2016 ; Her Majesty's Prison & Probation Service, 2018 ; Inspector of Custodial Services, 2015 ; Maschi et al., 2012 ; Mistry & Muhammad, 2015 ; Sindano & Swapp, 2019 ; Tilsed, 2019 ; Treacy et al., 2019 ). Comprehensive 36–40 h training on dementia was delivered for those working on specialist units, including one leading to a qualification (Brooke & Jackson, 2019 ; Brown, 2016 ; Gaston & Axford, 2018 ; Her Majesty's Prison & Probation Service, 2018 ; Moll, 2013 ). Much of the training was developed and delivered by charities, particularly dementia-related ones, as reported in eleven papers. Ongoing support and supervision was offered or recommended by some prisons, provided largely by health or social care staff or charities (Brooke & Jackson, 2019 ; Brown, 2016 ; Correctional Investigator Canada, 2019 ; Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ; Gaston & Axford, 2018 ; Maschi et al., 2012 ; Prisons and Probation Ombudsman, 2016 ; Sindano & Swapp, 2019 ; Treacy et al., 2019 ), with informal peer-to-peer support also described (Brown, 2016 ; Gaston & Axford, 2018 ; Treacy et al., 2019 ). The support and supervision received was found to be valuable (Brooke & Jackson, 2019 ; Brown, 2016 ; Treacy et al., 2019 ). Peer-supporter roles are listed in Table 9 .

A number of benefits to: (a) the peer supporters, (b) the prisoners they supported and, (c) the prison, were described, although formal evaluations were lacking (Brown, 2016 ; Christodoulou, 2012 ; Department of Health, 2007 ; du Toit et al., 2019 ; Gaston, 2018 ; Gaston & Axford, 2018 ; Goulding, 2013 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 ). This included: payment, development of skills which could be used on release, positive impact on progression through the system, and on self-confidence and compassion, and the creation of a more humane environment. However, frustration and distress amongst peer supporters largely when untrained and unsupported was also reported (Brooke & Jackson, 2019 ; Brown, 2016 ; Correctional Investigator Canada, 2019 ; Inspector of Custodial Services, 2015 ; Prisons and Probation Ombudsman, 2016 ; Treacy et al., 2019 ), and concerns raised in relation to an over-reliance on peers to do work that it is the statutory duty of health and social care to provide (Prisons and Probation Ombudsman, 2016 ; Treacy et al., 2019 ). This was a particular problem in light of personal care being prohibited for peer supporters in England and Wales (Her Majesty's Prison & Probation Service, 2018 ; Moll, 2013 ). It is also of note that the role of peer supporter may also attract the opprobrium of other prisoners, with reports that they have been seen as ‘snitches’ or ‘dogs’ in some areas (Brown, 2016 ; Goulding, 2013 ). In addition, in some prisons, the peer supporter role was not advocated due to: fear of litigation; fear of replacing staff with peers; belief that people should be acquiring more transferable skills, since many would be unable to undertake care work in the community due to their offence history (Brown, 2016 ; Goulding, 2013 ).

Accommodation

There were mixed views regarding accommodation for PLiPWD. A continuum of prison accommodation was suggested from independent to 24-h care (including assisted living) (Forsyth et al., 2020 ; Gaston & Axford, 2018 ; Williams et al., 2012 ). A number of papers ( n = 18) recommended that there should be some form of alternative, more appropriate accommodation developed, potentially regional, including secure facilities possibly with a palliative orientation (Hodel & Sanchez, 2013 ; Mistry & Muhammad, 2015 ; Sfera et al., 2014 ). However, there were concerns about the availability, costs and staffing of specialist units, and distances that family would have to travel to visit despite potential benefits (du Toit et al., 2019 ; Moore & Burtonwood, 2019 ). It was also suggested that PLiPWD should be released to live in the community instead (Correctional Investigator Canada, 2019 ).

Within prisons, there was a debate evident within the papers about whether PLiPWD should be accommodated in separate units or integrated within the general prison population, which had generated little clear evidence and mixed views (Brooke & Jackson, 2019 ; Dillon et al., 2019 ; Her Majesty's Prison & Probation Service, 2018 ; Treacy et al., 2019 ). Authors have suggested that specialist or separate wings focused on older people or those with dementia were safer, met peoples’ needs better, and offered better care, support and programmes than integrated units (Brown, 2014 ; Dillon et al., 2019 ; du Toit & Ng, 2022 ; du Toit et al., 2019 ; Goulding, 2013 ; Maschi et al., 2012 ; Murray, 2004 ; Treacy et al., 2019 ; Williams et al., 2012 ), as long as they were ‘opt-in’ for prisoners and staff (Correctional Investigator Canada, 2019 ; Moll, 2013 ; Treacy et al., 2019 ; Williams et al., 2012 ), and opportunities to get off the wing to socialise with others are provided (Treacy et al., 2019 ). The types of ‘specialist’ accommodation that PLiPWD were living in are reported in Table 10 . It is of note that papers reported a highly limited number of beds available in specialist units (Inspector of Custodial Services, 2015 ; Patterson et al., 2016 ; Turner, 2018 ), and that a number of older prisoner-specific prisons were being closed due to costs (Turner, 2018 ).

Four papers described the benefits of older people and those PLiPWD residing within the general prison population (Dillon et al., 2019 ; Her Majesty's Prison & Probation Service, 2018 ; Treacy et al., 2019 ; Williams et al., 2012 ). Those living with dementia reported a benefit from socialising with, and being cared for by, younger people (Dillon et al., 2019 ; Her Majesty's Prison & Probation Service, 2018 ; Williams et al., 2012 ). The presence of older people also reportedly calmed younger prisoners (Dillon et al., 2019 ; Her Majesty's Prison & Probation Service, 2018 ; Williams et al., 2012 ). Importantly, removing people from their prison social networks may have a detrimental effect (Williams et al., 2012 ), and living on specialist units can be stigmatising (Treacy et al., 2019 ).

Regime and activities

The maintenance of prisons regimes is the primary focus of prison officers (Brooke & Jackson, 2019 ). However, there was a reported need ( n = 19) for PLiPWD to have equal access to activities and services including work, education, gym, library and day centres where they exist, as well as a structured and varied regime on the wing on which they were accommodated, and support to access these. This support could include providing adequate seating (Welsh Government and Ministry of Justice, 2011 ), or giving prisoners more time to accomplish activities, and to assist if needed (Brooke & Jackson, 2019 ; Goulding, 2013 ; Her Majesty's Prison & Probation Service, 2018 ; Hodel & Sanchez, 2013 ). Other recommendations included an overall relaxation of regimes (Gaston & Axford, 2018 ; Treacy et al., 2019 ), an ‘open door’ policy (Brown, 2016 ; Cipriani et al., 2017 ; Goulding, 2013 ; Her Majesty's Inspectorate of Prisons, 2014 ; Her Majesty's Inspectorate of Prisons, 2017b ; Her Majesty's Prison & Probation Service, 2018 ; Treacy et al., 2019 ), more visible staff (The King's Fund, 2013 ), and creating a more communal social environment (Christodoulou, 2012 ). On-wing social activities are described in Table 11 .

Having on-wing work available or alternative means for prisoners who are unable to work to make money was also reportedly important (Christodoulou, 2012 ; Department of Health, 2007 ; Gaston, 2018 ; Gaston and Axford, 2018 ; Her Majesty's Inspectorate of Prisons, 2014 , 2016 , 2017b ; Her Majesty's Prison & Probation Service, 2018 ; Moll, 2013 ; Murray, 2004 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 ). It was suggested that people with dementia should have the chance to work if wanted, and adaptations could be made to work programmes or working days made shorter to facilitate this. Some prisons had specific roles which involved lighter, simple, repetitive tasks such as gardening (Baldwin & Leete, 2012 ; Brooke & Jackson, 2019 ; Inspector of Custodial Services, 2015 ; Moll, 2013 ; Treacy et al., 2019 ). Day centres existed in some prisons, or were thought to be feasible (Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ; Moll, 2013 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 ), and it was suggested that attendance at these could constitute meaningful paid activity (Her Majesty's Prison & Probation Service, 2018 ). The centres were largely developed and facilitated by charities, and ran a wide variety of social, therapeutic, recreational, arts and advice-centred activities (Her Majesty's Prison & Probation Service, 2018 ; Moll, 2013 ).

Equal access to educational activities, including rehabilitation and offending behaviour programmes, was highlighted as important, particularly where attendance is needed to facilitate people’s progression through the system (Booth, 2016 ; Brooke & Jackson, 2019 ; Dillon et al., 2019 ; Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ). Some prisons provided, or felt there was a need for, particular educational activities for PLiPWD and adaptations may be, or have been, made to learning materials and equipment, content and pace (Brooke & Jackson, 2019 ; Department of Health, 2007 ; Gaston, 2018 ; Gaston & Axford, 2018 ; Her Majesty's Prison & Probation Service, 2018 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 ). Dedicated library sessions have been designated in some prisons, and some libraries can and do stock specialist resources including books, audiobooks, reminiscence packs and archives of local photos, music and DVDs (Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ;Treacy et al., 2019 ; Williams, 2014 ). Educational materials could and have been available between sessions to aid memory with distance learning also possible (Brooke & Jackson, 2019 ; Her Majesty's Prison & Probation Service, 2018 ). Suggestions for alternatives for PLiPWD focused on activity and stimulation (du Toit & Ng, 2022 ; Gaston, 2018 ; Her Majesty's Prison & Probation Service, 2018 ), preparing for retirement classes (Department of Health, 2007 ), health promotion (Brooke et al., 2018 ; Christodoulou, 2012 ; Gaston & Axford, 2018 ; Her Majesty's Prison & Probation Service, 2018 ; Maschiet al., 2012 ; Murray, 2004 ; Welsh Government and Ministry of Justice, 2011 ), the arts (Brooke & Jackson, 2019 ) and IT classes (Her Majesty's Prison & Probation Service, 2018 ). Prisoner forums or representative could also be consulted regarding regimes and activities (Moll, 2013 ; Her Majesty's Prison & Probation Service, 2018 ; Welsh Government and Ministry of Justice, 2011 ). Challenges to regimen and activities are described in Table 12 .

Environment

A large number ( n = 42) of the included papers discussed changes that prisons had made, or should make, to the built environment in order to be more suitable for PLiPWD – in one study in England and Wales, around half of prisons surveyed had made such environmental modifications (Forsyth et al., 2020 ). These focused on: (i) prisoners’ cells, (ii) bathrooms, (iii) dining hall, (iv) outside space and recreation areas, and (v) overall general prison environment (Table 13 ).

Problematically, the age and dementia-inappropriateness of buildings are considered a challenge (Baldwin & Leete, 2012 ; Brown, 2016 ; Dementia Action Alliance, 2017 ; Forsyth et al., 2020 ; Goulding, 2013 ; Inspector of Custodial Services, 2015 ; Mistry & Muhammad, 2015 ; Prisons and Probation Ombudsman, 2016 ; Treacy et al., 2019 ). Difficulties in navigating prisons where everywhere looks the same (Dementia Action Alliance, 2017 ; Murray, 2004 ; Treacy et al., 2019 ), and the lack of budget (HMP Littlehey, 2016 ; HMP Littlehey, 2016 ; Inspector of Custodial Services, 2015 ; Treacy et al., 2019 ) were also reported issues. It was suggested that the use of dementia-friendly environmental checklists could be useful, potentially with input from occupational therapists, health and social care, and dementia charities and in-house education, work and estates departments (Brown, 2014 ; Christodoulou, 2012 ; Dillon et al., 2019 ; Goulding, 2013 ; HMP Littlehey, 2016 ; Her Majesty's Prison & Probation Service, 2018 ; Hodel & Sanchez, 2013 ; Peacock et al., 2018 ; Sindano & Swapp, 2019 ; Treacy et al., 2019 ). Hope was expressed that newly built prisons would be more dementia-friendly (Dementia Action Alliance, 2017 ; Her Majesty's Prison & Probation Service, 2018 ; Williams et al., 2012 ).

Formal policies and procedures should be in place to help maintain links between family and prisoners, and to foster an understanding of the central importance of families particularly for PLiPWD (Her Majesty's Inspectorate of Prisons, 2016 ; Treacy et al., 2019 ). Some papers described how prisons could support contact by: giving help and additional time to make telephone calls and arranging visits in quieter spaces (Her Majesty's Prison & Probation Service, 2018 ; Prisons and Probation Ombudsman, 2016 ; Treacy et al., 2019 ); increasing the number of visits (Jennings, 2009 ); and allowing for accumulated visits or transfers to other prisons for visits closer to home (Her Majesty's Prison & Probation Service, 2018 ). Family communication – additional information can be found in Table 14 .

External organisations

One review suggested that external voluntary agencies were not often contacted or referred to, despite their potential benefits in terms of costs and support for staff and PLiPWDs (du Toit et al., 2019 ). However, other papers reported that charities for PLiPWD, or older people, were involved in (or were recommended to be involved in): designing and/or delivering dementia training; being part of MDTs; informing the design of referral processes, screening, assessment and case finding tools; consulting on environmental design; creating and delivering social care plans (including running activity centres); advice and support; advocacy and; co-facilitating a cognitive stimulation therapy group (Alzheimer’s Society 2018 ; Brooke et al., 2018 ; Brown, 2014 , 2016 ; Correctional Investigator Canada, 2019 ; Department of Health, 2007 ; du Toit & Ng, 2022 ; du Toit et al., 2019 ; Gaston, 2018 ; Gaston & Axford, 2018 ; Goulding, 2013 ; Her Majesty's Inspectorate of Prisons, 2014 ; HMP Hull, 2015 ; Her Majesty's Prison & Probation Service, 2018 ; Hodel & Sanchez, 2013 ; Moll, 2013 ; Peacock et al., 2018 ; Prisons and Probation Ombudsman, 2016 ; Sindano & Swapp, 2019 ; Tilsed, 2019 ; Treacy et al., 2019 ; Williams, 2014 ). It was also recommended that external organisations need to have a better knowledge and understanding of prisons and people living in prison, in order to better manage risk, and for clear information sharing protocols (du Toit & Ng, 2022 ).

(iv) Transfers

During the course of their sentence, people in prison may be transferred to other prisons for various reasons or to receive treatment in hospital. The need for MDT transfer plans to be developed was reported (Welsh Government and Ministry of Justice, 2011 ), as was the need to limit the number of prisoner transfers as moving accommodation is likely to have an adverse effect (Her Majesty's Prison & Probation Service, 2018 ; Patterson et al., 2016 ). It was recommended that transfers should take the distance from family and friends into account (Her Majesty's Prison & Probation Service, 2018 ), and that the ‘receiving’ facility (prison or healthcare setting) should be liaised with regarding health and social care, and risk (Her Majesty's Prison & Probation Service, 2018 ; Welsh Government and Ministry of Justice, 2011 ) to ensure continuity of care (Cipriani et al., 2017 ). A standard document transfer protocol was also postulated as useful, as documents need to be forwarded quickly as well (Brown, 2016 ; Tilsed, 2019 ; Welsh Government and Ministry of Justice, 2011 ). At the receiving facility, it was suggested that assessments and care plans should be reviewed on the day of the transfer (Brown, 2016 ; Her Majesty's Prison & Probation Service, 2018 ; National Institute for Health and Care Excellence, 2017 ; Welsh Government, 2014 ), and for re-inductions to be facilitated for prison transfers (Her Majesty's Prison & Probation Service, 2018 ).

(v) Release and resettlement

Most prisoners will be released from prison at the end of their sentence, although a number may die before their time is served. A number of areas were highlighted regarding the release and resettlement of PLiPWD, including the possibility of early release due to dementia.

Early release

A number of papers advocated for compassionate release policies and their actual use, or alternative custodial placements such as halfway houses or secure nursing homes, that would effectively result in the early release of PLiPWD (Brown, 2016 ; Cipriani et al., 2017 ; Correctional Investigator Canada, 2019 ; Dementia Action Alliance, 2017 ; Department of Health, 2007 ; du Toit & Ng, 2022 ; du Toit et al., 2019 ; Fazel et al., 2002 ; Gaston & Axford, 2018 ; Goulding, 2013 ; Her Majesty's Prison & Probation Service, 2018 ; Hodel & Sanchez, 2013 ; Inspector of Custodial Services, 2015 ; Maschi et al., 2012 ; Mistry & Muhammad, 2015 ; Pandey et al., 2021 ; Turner, 2018 ; Williams et al., 2012 ). Although, it has also been noted that early release may not be a popular idea for some sections of the community (du Toit et al., 2019 ; Garavito, 2020 ), it was also suggested that raising community awareness of dementia may ameliorate this (du Toit & Ng, 2022 ). It was reported that prisoners with dementia should be considered in any criteria set forth for early release, particularly given the high cost/low risk ratio which they represent (Baldwin & Leete, 2012 ; Correctional Investigator Canada, 2019 ; Department of Health, 2007 ; Goulding, 2013 ; Her Majesty's Prison & Probation Service, 2018 ; Inspector of Custodial Services, 2015 ; Maschi et al., 2012 ; Murray, 2004 ; Williams et al., 2012 ). For prisoners who do not understand the aims of prison, continuing to hold them may be a contravention of human rights and equality laws – particularly where health and social care is inadequate (Baldwin & Leete, 2012 ; Dementia Action Alliance, 2017 ; Fazel et al., 2002 ; Gaston & Axford, 2018 ; Murray, 2004 ). It was also emphasised that the existence of units and programmes for PLiPWD should not be used to legitimise prison as an appropriate place for PLiPWD (Correctional Investigator Canada, 2019 ). More information can be found in Table 15 .

Resettlement

Ten different areas were identified in the literature which related to the issues PLiPWD leaving prison may face on their release and resettlement into the community, these were:

(a) In-prison release preparation

Specific pre-release programmes or services for older people or those living with dementia may be required (Department of Health, 2007 ; Williams et al., 2012 ), with prisoners being cognitively screened prior to release (Goulding, 2013 ), although the latter was only found in 10% of prisons in one study (Forsyth et al., 2020 ). Other suggestions for programme content included: self-efficacy, health, staving off dementia and associated anxiety, accessing services, addressing institutionalisation, setting up email addresses, and the provision of information packs on national, regional and local services and resources (Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ; Williams et al., 2012 ).

It has been suggested that release plans and transitions be facilitated by an MDT including prisoners, the voluntary sector, offender managers, and other appropriate community-based organisations (du Toit et al., 2019 ; Feczko, 2014 ; Goulding, 2013 ; Her Majesty's Prison & Probation Service, 2018 ; Inspector of Custodial Services, 2015 ; Moll, 2013 ; Welsh Government and Ministry of Justice, 2011 ). Recommended plan content included: risk management strategies, health, social care, housing, finance, employment, leisure and voluntary sector considerations (Welsh Government and Ministry of Justice, 2011 ). It was also suggested that Circles of Support and Accountability (CoSA), primarily associated with sex offenders, could be set up for PLiPWD as a means to support those leaving prison and settling back into the community particularly without family support (Her Majesty's Prison & Probation Service, 2018 ).

Challenges to release preparation were identified as: a lack of resources, (Turner, 2018 ) the lack of clarity regarding staff resettlement roles (Inspector of Custodial Services, 2015 ), and the lack of resettlement provision offered at sex offender prisons in England and Wales (Her Majesty's Prison & Probation Service, 2018 ).

A number of papers reported the key role that family and friends can or do play in supporting PLiPWD leaving prison, and that this should be supported or facilitated by prison staff (Brown, 2016 ; Her Majesty's Prison & Probation Service, 2018 ; Goulding, 2013 ). Initially this could include encouraging diagnosis disclosure (Dillon et al., 2019 ), using prison leave to maintain relationships (Her Majesty's Prison & Probation Service, 2018 ), involvement in discharge planning (Welsh Government and Ministry of Justice, 2011 ), and placing prison leavers close to family upon release and ensuring family are supported (Correctional Investigator Canada, 2019 ; Gaston & Axford, 2018 ). Where PLiPWD lack family, setting up CoSAs as described above may be useful (Her Majesty's Prison & Probation Service, 2018 ).

It was suggested that probation staff should have training to work with older people, and that some offender managers could specialise in this work (Department of Health, 2007 ; Welsh Government and Ministry of Justice, 2011 ). Probation officers or offender managers are or can be involved in resettlement planning, (Her Majesty's Prison & Probation Service, 2018 ; Welsh Government and Ministry of Justice, 2011 ), arranging accommodation (Inspector of Custodial Services, 2015 ), liaising with agencies such as health care or social services, checking that PLiPWD are accessing these services and disseminating reports of to-be released prisoners to relevant parties (Department of Health, 2007 ; Moll, 2013 ; Welsh Government and Ministry of Justice, 2011 ). Importantly, the forwarding of important documents to offender managers by the prison should be routine (Department of Health, 2007 ; Moll, 2013 ). It was also recommended that probation staff should visit people in prison before release if they live out of area (Department of Health, 2007 ). The work of probation services was reportedly hampered by limited resources (Brown, 2016 ).

Continuity of care upon release can be difficult, and it was suggested that it could be a role of prison healthcare to ensure this (including registering with the local GP and dentist (Cipriani et al., 2017 ; Department of Health, 2007 ; Gaston, 2018 ; Gaston & Axford, 2018 ; Her Majesty's Prison & Probation Service, 2018 ; Inspector of Custodial Services, 2015 ; Welsh Government and Ministry of Justice, 2011 ). There appeared to be some differences regarding the distribution of full healthcare reports to offender managers and other appropriate agencies with some prisons sending them, some only if requested, and some not providing them on grounds of confidentiality (Moll, 2013 ). Typically, it was recommended that it was better for to-be released older prisoners if these reports were disseminated (Department of Health, 2007 ). It was also suggested that healthcare staff in prison and from the community form part of multi-disciplinary release planning, and that these plans include health considerations and healthcare staff advice on issues of accommodation (du Toit & Ng, 2022 ; Inspector of Custodial Services, 2015 ; Moll, 2013 ; Welsh Government and Ministry of Justice, 2011 ).

(e) Social care

Some papers reported that social workers can and should be involved in the process of resettlement (Department of Health, 2007 ; Welsh Government and Ministry of Justice, 2011 ) and release preparation (Goulding, 2013 ). Continuity of social care arranged with the local authority was also recommended (Her Majesty's Prison & Probation Service, 2018 ; Welsh Government and Ministry of Justice, 2011 ).

(f) Accommodation

Release planning should include plans for accommodation, and involve housing agencies or care services in the community in that planning (Welsh Government and Ministry of Justice, 2011 ). Importantly, people in prison may need help in registering for housing, and their homes may be in need of adaptation in response to their health or social care needs (Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ). Nursing homes and other care providing facilities were reported to be reluctant to accommodate people who have been in prison (Brown, 2014 ; Brown, 2016 ; Booth, 2016 ; Correctional Investigator Canada, 2019 ; du Toit et al., 2019 ; Gaston, 2018 ; Garavito, 2020 ; Goulding, 2013 ; Inspector of Custodial Services, 2015 ). This was described as particularly the case for those who were living with dementia (Brown, 2014 ; Correctional Investigator Canada, 2019 ; Dillon et al., 2019 ), with further issues reported in accommodating those who have committed sex offences (Brown, 2014 , 2016 ; Dillon et al., 2019 ; Garavito, 2020 ; Inspector of Custodial Services, 2015 ). Concerns regarding the safety of other residents and the views of their families, and the rights of victims in general, were cited as reasons behind these placement difficulties (Brown, 2014 ; Goulding, 2013 ) – one paper reported that there had been community protests (Brown, 2016 ).

It was suggested that prisons need to build better relationships with care providers in the community, which had reportedly been forged by some (Brown, 2016 ; Goulding, 2013 ; Inspector of Custodial Services, 2015 ), and that they could also provide education and support to these services (Booth, 2016 ). However, it was also noted that there may be a need for specialist residential units to be created in the community for people released from prison with dementia (Inspector of Custodial Services, 2015 ), with an example of a state-run facility for ex-prisoners in the United States (Goulding, 2013 ), and particular attention for younger ex-prisoners with dementia (Brown, 2014 ). A number of papers reported that if accommodation could not be arranged for people, this largely resulted in them remaining in prison until it was (Correctional Investigator Canada, 2019 ; Goulding, 2013 ; Inspector of Custodial Services, 2015 ; Peacock et al., 2018 ; Soones et al., 2014 ).

(g) Finance

Imprisonment likely leads to a loss of income, meaning that older prisoners who may have served more lengthy sentences are likely to be poorer, particularly if unable to work in prison (Baldwin & Leete, 2012 ; Gaston, 2018 ). Therefore, it was suggested that release planning ought to include issues of finance (Welsh Government and Ministry of Justice, 2011 ). Given that it has been suggested that people in prison should be given advice on pensions and welfare benefits, and help to arrange these (Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ; Goulding, 2013 ), addressing this would seem to be an area of particular use for older people leaving prison who may have additional problems in these areas, and for those who may need assistance in arranging their financial affairs because of their deteriorating health problems.

(h) Employment and education

People’s employment prospects are likely to be impacted upon release from prison, particularly for older people who may have served long sentences (Gaston, 2018 ). Where appropriate, it was recommended that release planning should include issues around employment (Welsh Government and Ministry of Justice, 2011 ), that information packs for people should include sections on education and employment, and that it could be useful to help people make links with the Department for Work and Pensions (Her Majesty's Prison & Probation Service, 2018 ).

(i) Leisure

Leisure activities and resources could be considered in release planning, and included in pre-release information packs for prisoners (Her Majesty's Prison & Probation Service, 2018 ; Welsh Government and Ministry of Justice, 2011 ).

(j) Charities and voluntary sector organisations

It was recommended in a number of papers that charity and voluntary sector organisations working with PLiPWD be involved in release planning (Department of Health, 2007 ; du Toit et al., 2019 ; Her Majesty's Prison & Probation Service, 2018 ; Moll, 2013 ; Welsh Government and Ministry of Justice, 2011 ), continuity of care (Moll, 2013 ), and in providing support during the transition and after (du Toit & Ng, 2022 ; Welsh Government and Ministry of Justice, 2011 ). It was also suggested that in general it would be useful for PLiPWD to have contact with these organisations (Department of Health, 2007 ; Her Majesty's Prison & Probation Service, 2018 ; Inspector of Custodial Services, 2015 ), and that they may be well-placed to develop information packs for prisoners on release regarding local amenities, services and resources (Her Majesty's Prison & Probation Service, 2018 ).

(vi) Cross-cutting themes

Eight more generalised concerns were also described which had a clear impact on the passage of PLiPWD through prison, on release and resettlement in the community, and on the issues raised thus far in the review.

Principles-philosophy

The principles suggested to underpin the support of PLiPWD are that it should be person-centred, holistic, adhere to human rights and dignity principles, proactive, health promoting, and enabling – making choices but supported if needed (Brown, 2014 , 2016 ; Christodoulou, 2012 ; Cipriani et al., 2017 ; Correctional Investigator Canada, 2019 ; Department of Health, 2007 ; Dillon et al., 2019 ; du Toit & Ng, 2022 ; Gaston & Axford, 2018 ; Her Majesty's Inspectorate of Prisons, 2017b ; Her Majesty's Prison & Probation Service, 2018 ; Mackay, 2015 ; Maschi et al., 2012 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 ; Wilson & Barboza, 2010 ). Conversely, clashes in philosophies between prison staff, and health and social care staff have been reported with security trumping care in many cases, which can have a negative impact (du Toit & Ng, 2022 ; Gaston, 2018 ; Gaston & Axford, 2018 ; Goulding, 2013 ; Mackay, 2015 ; Murray, 2004 ; Patterson et al., 2016 ; Prisons and Probation Ombudsman, 2016 ; Treacy et al., 2019 ; Williams, 2014 ). It was suggested that positioning dementia as more than just a health issue and fostering a whole-prison care-custody model or approach, with clearly defined roles for ‘care’ and ‘custody’, may be useful in resolving this (du Toit & Ng, 2022 ; Public Health England, 2017b ; Welsh Government and Ministry of Justice, 2011 ).

A number of papers ( n = 15) reported that budget and resource limitations had a variety of negative impacts including difficulties in providing: appropriate assessment, support and accommodation to PLiPWD; specialist accommodations, plans for which were then curtailed; delivering programmes and activities; healthcare cover; and, staff training (Booth, 2016 ; Christodoulou, 2012 ; Correctional Investigator Canada, 2019 ; Dementia Action Alliance, 2017 ; Dillon et al., 2019 ; du Toit et al., 2019 ; du Toit & Ng, 2022 ; Goulding, 2013 ; HMP Hull, 2015 ; Jennings, 2009 ; Mackay, 2015 ; Moll, 2013 ; Moore & Burtonwood, 2019 ; Pandey et al., 2021 ; Patterson et al., 2016 ; Peacock et al., 2018 ; Treacy et al., 2019 ; Turner, 2018 ). Ultimately, lack of resources has reportedly led to a system that is not able to cope appropriately with PLiPWD (Moll, 2013 ; Williams et al., 2012 ; Wilson & Barboza, 2010 ), with associated problems transferring out of the prison system into probation and care systems when people are released (Williams et al., 2012 ).

It has been suggested that PLiPWD in prison should be treated as if they have capacity to make decisions such as giving or withholding consent for treatment, unless it is proven otherwise. This is consistent with legislation such as the Mental Capacity Act (Prisons and Probation Ombudsman, 2016 ). It has been recommended that healthcare staff should conduct capacity assessments if there are concerns (National Institute for Health and Care Excellence, 2017 ; Welsh Government and Ministry of Justice, 2011 ), and be trained to do so (Maschi et al., 2012 ; Welsh Government, 2014 ). It is of note that an ombudsman report showed that PLiPWD who died lacked access to mental capacity assessments (Peacock et al., 2018 ). For PLiPWD, who are likely to lack capacity as their condition progresses, early education about, and development of, advance directives has been advocated (Brown, 2016 ; Cipriani et al., 2017 ; Inspector of Custodial Services, 2015 ; Maschi et al., 2012 ; Prisons and Probation Ombudsman, 2016 ), and staff should be trained on this (Maschi et al., 2012 ). It has also been suggested that family members, independent mental capacity advocates or healthcare proxies could or should be used for PLiPWD who lack capacity in making care, welfare and financial decisions (Brown, 2016 ; Soones et al., 2014 ), supported by legislation and oversight, as opposed to prison or healthcare staff making decisions (Correctional Investigator Canada, 2019 ).

The issue of ‘risk’ related to PLiPWD revolves around four areas: (i) assessment, (ii) management, (iii) disciplinary procedures, and (iv) safeguarding. Full details can be found in Table 16 .

There were a number of additional facets to risk concerns regarding PLiPWD described in the papers. There were concerns that the lack of understanding of the impact of dementia on people’s behaviour could ultimately lead to people being held in prison for longer periods on account of seemingly transgressive or aggressive behaviour that could in fact be related to their dementia difficulties (Dementia Action Alliance, 2017 ; Mistry & Muhammad, 2015 ; Treacy et al., 2019 ). In one study, a prisoner with dementia was transferred to another prison because staff felt that they were ‘grooming’ an officer (Treacy et al., 2019 ), likely lengthening their overall prison stay. There was also a recurring issue in fatal incidents investigations in England and Wales of prisoners being restrained whilst dying in hospital, a practice described as unnecessary in light of their likely frail state (Peacock et al., 2018 ; Prisons and Probation Ombudsman, 2016 ). One paper suggested linking future accommodation options and considerations for Release on Temporary Licence to a PLiPWD’s risk of reoffending, as well as the severity of their symptoms (Forsyth et al., 2020 ). Moore and Burtonwood ( 2019 ) also observed that a lack of risk assessment protocols was a barrier to release of PLiPWD., and as Table 16 suggests, a comprehensive risk assessment, applied by appropriately trained staff should make health and its impact on future offending more salient to aid this.

There were recommendations that PLiPWD should have the opportunity to make choices in their treatment and care. This included input into care plans or making informed decisions about their care (Department of Health, 2007 ; du Toit & Ng, 2022 ; National Institute for Health and Care Excellence, 2017 ; Welsh Government and Ministry of Justice, 2011 ), as well as developing advance directives particularly early in a person’s sentence (Brown, 2016 ; Cipriani et al., 2017 ; Inspector of Custodial Services, 2015 ; Maschi et al., 2012 ; Pandey et al., 2021 ; Peacock et al., 2019 ; Prisons and Probation Ombudsman, 2016 ), and choosing ‘preferred’ places to die (Her Majesty's Prison & Probation Service, 2018 ).

Protected characteristics

There was a reported need for culturally appropriate assessments, treatment and activities (Brooke et al., 2018 ; Department of Health, 2007 ; Hamada, 2015 ; Welsh Government and Ministry of Justice, 2011 ), spiritual support (Welsh Government and Ministry of Justice, 2011 ), multilingual information (Welsh Government and Ministry of Justice, 2011 ), and the recognition of gender differences in dementia healthcare needs (Brown, 2014 ; Department of Health, 2007 ; Williams et al., 2012 ). It was also highlighted that racism makes the experience of living with dementia in prison more problematic (Brooke et al., 2018 ; Brown, 2014 ; Correctional Investigator Canada, 2019 ). There were some examples of policy and practice within prisons which considered some protected characteristics: assessment tools in different languages (Patterson et al., 2016 ), additional support for PLiPWD to plan care (Department of Health, 2007 ; Welsh Government and Ministry of Justice, 2011 ), and the development of culturally appropriate care planning (Hamada, 2015 ). Hamada ( 2015 ) also advocated assessment and treatment that was culturally ‘competent’ and respectful, and which acknowledged the importance of culture and diversity.

An overall need to tackle dementia- and age-related stigma was also reported in some papers, and the need to foster cultures that are age-respectful should be reflected in staff training (Department of Health, 2007 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 ), In addition, practices which openly discriminate such as the lack of: dedicated dementia resources (Turner, 2018 ), appropriate lower category prison places (Department of Health, 2007 ; Welsh Government and Ministry of Justice, 2011 ), and appropriate accommodation on release, which at times prevents release, should also be challenged (Correctional Investigator Canada, 2019 ; Forsyth et al., 2020 ; Ministry of Justice, 2013 ; Prisons and Probation Ombudsman, 2016 ). There was also a lack of research into the interaction between protected characteristics and dementia in prison (Brooke & Jackson, 2019 ; Treacy et al., 2019 ; Williams et al., 2012 ).

Collaboration

Many papers advocated the need for prisons and specialist dementia units to adopt a collaborative MDT approach drawing from staff teams across the prison regarding: the identification and support of prisoners with dementia, care planning, the disciplinary process, the development, dissemination and implementation of policy, and in environmental change and the building of new prisons (Brooke et al., 2018 ; Brown, 2014 , 2016 ; Christodoulou, 2012 ; Cipriani et al., 2017 ; Dillon et al., 2019 ; Department of Health, 2007 ; Feczko, 2014 ; Forsyth et al., 2020 ; Gaston & Axford, 2018 ; Her Majesty's Inspectorate of Prisons, 2014 , 2016 ; HMP Hull, 2015 ; HMP Littlehey, 2016 ; Her Majesty's Prison & Probation Service, 2018 ; Inspector of Custodial Services, 2015 ; Moll, 2013 ; Patterson et al., 2016 ; Peacock et al., 2018 ; Peacock, 2019 ; Prisons and Probation Ombudsman, 2016 ; Sindano & Swapp, 2019 ; The King’s Fund 2013 ; Tilsed, 2019 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 , 2014 ; Williams, 2014 ). There were examples of prisoners collaborating with staff in the care of PLiPWD as peer supporters, and having joint staff-prisoner supervision and training (Brooke & Jackson, 2019 ), of joint staff-prisoner wing meetings in one prison (Treacy et al., 2019 ), and of the co-designing of services and activities in others (Her Majesty's Prison & Probation Service, 2018 ; Treacy et al., 2019 ). It was suggested that this collaborative way of working should be supported by an information sharing protocol, clear definitions of staff and peer supporter roles and responsibilities, and training (Brooke & Jackson, 2019 ; Dillon et al., 2019 ; du Toit & Ng, 2022 ; HMP Littlehey, 2016 ; Turner, 2018 ). It was reported that there had been a lack of communication and coordination of this process in some prisons which had a negative impact on all involved (Brooke & Rybacka, 2020 ; Forsyth et al., 2020 ; Moll, 2013 ; Prisons and Probation Ombudsman, 2016 ).

It was also suggested that the prisons collaborate with healthcare, hospice and dementia specialists in the community and with external charitable organisations (Brooke et al., 2018 ; Brown, 2014 ; Cipriani et al., 2017 ; du Toit & Ng, 2022 ; Gaston, 2018 ; Gaston & Axford, 2018 ; Goulding, 2013 ; HMP Hull, 2015 ; HMP Littlehey, 2016 ; Her Majesty's Prison & Probation Service, 2018 ; Moll, 2013 ; Peacock, 2019 ; Prisons and Probation Ombudsman, 2016 ; Sindano & Swapp, 2019 ; Tilsed, 2019 ; Treacy et al., 2019 ; Welsh Government and Ministry of Justice, 2011 ; Williams, 2014 ). In addition, inter-prison networks were recommended to be developed to share good practice across prisons (Dementia Action Alliance, 2017 ; Moll, 2013 ; Peacock et al., 2019 ; Prisons and Probation Ombudsman, 2016 ).

Information-sharing

A number of papers ( n = 7) recommended the need for a clear information sharing protocol regarding the assessment and support of PLiPWD (Brooke et al., 2018 ; Dillon et al., 2019 ; Department of Health, 2007 ; Goulding, 2013 ; Moll, 2013 ; Tilsed, 2019 ; Welsh Government and Ministry of Justice, 2011 ), or a register (Forsyth et al., 2020 ). Particular attention to the interface between healthcare and prison staff and peer supporters was suggested, where it has been reported that privacy regulations have sometimes prevented contributions to collateral histories (Feczko, 2014 ) and the sharing of care plans, impairing their ability to offer appropriate support (Inspector of Custodial Services, 2015 ). Also, it may be against the wishes of the person with dementia, and informed consent should be sought (Forsyth et al., 2020 ; Moll, 2013 ). This lack of information can have a detrimental effect on a person’s health and wellbeing (Brown, 2014 , 2016 ; Feczko, 2014 ; Inspector of Custodial Services, 2015 ), and so discussion of this was highlighted as important, particularly where the safety of the person or others were concerned (National Institute for Health and Care Excellence, 2017 ). A care plan which gives only very basic information to staff and peer supporters was used in a couple of prisons (Goulding, 2013 ; Williams, 2014 ).

There also appeared to be variance with respect to whether healthcare staff disclose a dementia diagnosis to the person diagnosed with dementia. A couple of prisons’ policy was to share a diagnosis and involve family in doing so (Maschi et al., 2012 ; Welsh Government and Ministry of Justice, 2011 ; Wilson & Barboza, 2010 ), however, in one prison disclosed if a person was judged to be able to cope with it, and another only disclosed if asked (Brown, 2016 ). The importance of disclosure to family allowing them to contribute to assessments, planning and support was also emphasised in some papers (Brown, 2016 ; Dillon et al., 2019 ; National Institute for Health and Care Excellence, 2017 ; Welsh Government and Ministry of Justice, 2011 ).

This review has explored the literature regarding all parts of the custodial process and its impact on people living in prison with cognitive impairment and dementia, which includes: reception, assessment, allocation, training, policy, healthcare, accommodation, adaptation, routine, access to family and external agencies, transfer and resettlement. We found evidence that problems had been identified in each of these parts of the process. We also identified a number of cross-cutting themes which interacted with the issues identified across the prison journey including: principles or philosophy regarding care; capacity; resources; considerations of risk; scope for choice; peoples’ protected characteristics; collaboration; and, information sharing. Broadly, our findings were similar to those found in previous reviews, regarding the problems with the prison process identified, and the lack of robust outcomes, and policy guidance regarding PLiPWD (Brooke and Rybacka, 2020 ; Peacock et al., 2019 ).

The aim of this review was to identify areas of good practice and for recommendations that could inform the development of prison dementia care pathways. There is a considerable breadth to the findings, but the main recommendations that have arisen from the review are:

To screen prisoners for cognitive difficulties at reception, from either 50 or 55 years

An initial older-person specific health and social care assessment, post-screening – from either 50 or 55 years, and repeated (from 3 – 12 months)

A spectrum of healthcare to be delivered including preventative, long-term and palliative care, with continuity of care upon release, and in tandem with social care

Mixed views about appropriate accommodation, but it needs to run along a continuum from independent living to 24-h care, with decisions possibly made after health assessments

Environments need to be made more older-person or dementia friendly, using checklists available, and with the voluntary sector as potential partners

A need for prison staff training on dementia, and further training for healthcare staff

The use of peer supporters was broadly reported positively, and were seemingly frequently used. However, there needs to be adequate training and support, and not to be used to do the work that is the statutory duty of health and social care staff

Equal access to activities and services, especially programmes which help people move through the system (such as offending behaviour), as well as opportunities to earn additional monies, and that provide structure and routine on wings

The maintenance of family links, and for families to be supported, are important for PLiPWD, and may be particularly so on release and resettlement

Prisons may also need to work with external care agencies to ensure placements upon release, or alternative specialist care facilities may need to be created

The main barriers to implementing these recommendations are a lack of policy or guidance at local, regional and national levels to support staff in working with PLiPWD, and also the lack of budget and resources available. The latter would also include infrastructure issues, such that a number of prisons are not appropriate for people living with dementia, and could be expensive to modify to become so, coupled with a lack of currently available alternative facilities for PLiPWD to be released to in the community. The lack of use of compassionate release is also an issue here, including during the COVID-19 pandemic, with only 54 people released (Halliday & Hewson, 2022 ). Lastly, the roles that each professional and peer group had regarding PLiPWD needed clarification in some prisons, including some resolution of the ‘clash’ of philosophies (control v care) underpinning this.

In terms of ‘solutions’, multiple organisations have advocated for years for the need for national policy to assist prisons with older people in prison, including those living with dementia (Cornish et al., 2016 ; HM Inspectorate of Prisons, 2004 , 2019 ; Prisons & Probation Ombudsman, 2016 , 2017 ). This was eventually accepted and commissioned by the UK government, although it has not been released as yet (Justice Committee, 2020 ). It has also been suggested that at a more local level, existing policies could be adapted to be more appropriate for PLiPWD – such as restraint policies for frail prisoners, and disciplinary procedures which reflect the impact that dementia may have on behaviour (Department of Health, 2007 ; Treacy et al., 2019 ). Considerations around capacity and consent would need to be weaved in, as well as a focus on the intersection with other protected characteristics. These adaptations would also need to extend to services and activities to ensure that people have equal access and opportunities. A number of reports highlighted the contribution that greater collaboration with partners in external health and social care teams could have, as well as partnerships with the voluntary sector. These could potentially assist in multiple areas including training staff and peer supporters, providing activities, assisting release preparation, at a relatively low cost, to high benefit. There were some recommendations that prisons adopt a whole-prison approach to dementia that focuses on being person-centred, health and human rights focused that may help to ameliorate some differences in philosophical approach between various staff and peer groups in prisons.

A number of potential areas for future research were also indicated by the literature, which would also support the development of prison pathways. These would include: (i) induction to prison, and (ii) release and resettlement from prison, which are important beginning and end-points, but which are under-researched; (iii) the validation of a screening tool for use in prisons, and the development or adaptation of prison-specific health and social care assessments; (iv) the interaction of protected characteristics and dementia, and the need for more culturally and gender aware pathways; (v) the paucity of research conducted in low and middle-income countries, that needs to be addressed; (vi) dementia and age-related stigma in prisons; and (vii) evaluations of all elements of the prison pathway for PLiPWD to undertaken including training, the role of peer supporters, and targeted programmes.

Strengths and limitations of the review

One key strength of this review is its comprehensiveness, particularly as it includes much grey literature. Given the lack of robust evaluation in this area, it was felt that this was necessary to represent the volume of work that has nonetheless taken place. There are, however, a number of limitations of this review. Firstly, despite the use of broad search terms, there may be the possibility that some relevant research was missed, either because of deficiencies in our searches or because of publication bias. Additionally, whilst there are twenty-two guidance and inspection documents included in this review, it is possible that some grey literature might also remain unidentified, particularly outside of the UK where the review was undertaken. Secondly, this review may be subject to a selection bias, as the yielded search results might have included literature that were excluded but which may have indirectly impacted upon the care pathways elements explored in the review. There is also a language bias, and whilst this may reflect the languages spoken by the review team members, it is also reflective of the “northern epistemic hegemony” (Aas, 2012 ), that also may have resulted in the review being largely populated by papers from high income countries. Thirdly, no formal assessment of study quality was undertaken. This is in keeping with scoping review methodology which focuses on breadth, but is nonetheless an important shortcoming inherent in scoping reviews more generally (Arksey & O’Malley, 2005 ).

We have completed the most comprehensive review of the literature on PLiPWD in prisons to date that we have found, including a synthesis of the extensive grey literature, and found important gaps in the literature. Our review includes a mixture of academic research, policy and position papers which identified an increasing number of prisoners with dementia or cognitive impairment as an issue, but there were more limited descriptions of what should be done, and even less describing implementation of these. Most of the literature came from developed nations where extensive assessment and care services are in place for PWD in the community, although a key question is whether prison populations are given easy access to these existing services or whether bespoke services for prisoners are required. We suggest this literature now needs to be drawn together to inform interventions for PLiPWD in the criminal justice system which can be piloted and evaluated, and inform the development of robust dementia care pathways for prisons.

Availability of data and materials

All data and materials used in this review are included in this article and its appendices.

There is no standard cut-off age for older people living in prison, but it is typically set at least ten to fifteen years lower than the general population. People in prison are thought to age more rapidly due to both pre- and post-imprisonment chaotic lifestyles, substance misuse and less healthcare access and use, as well as the ‘pains of imprisonment’. See Williams et al., ( 2012 ) for further discussion.
