Integrative reviews within healthcare promote a holistic understanding of the research topic. Structure and a comprehensive approach within reviews are important to ensure the reliability in their findings.

This paper aims to provide a framework for novice nursing researchers undertaking integrative reviews.

Established methods to form a research question, search literature, extract data, critically appraise extracted data and analyse review findings are discussed and exemplified using the authors’ own review as a comprehensive and reliable approach for the novice nursing researcher undertaking an integrative literature review.

Providing a comprehensive audit trail that details how an integrative literature review has been conducted increases and ensures the results are reproducible. The use of established tools to structure the various components of an integrative review increases robustness and readers’ confidence in the review findings.

Implications for practice

Novice nursing researchers may increase the reliability of their results by employing a framework to guide them through the process of conducting an integrative review.

A literature review is a critical analysis of published research literature based on a specified topic ( Pluye et al., 2016 ). Literature reviews identify literature then examine its strengths and weaknesses to determine gaps in knowledge ( Pluye et al. 2016 ). Literature reviews are an integral aspect of research projects; indeed, many reviews constitute a publication in themselves ( Snyder, 2019 ). There are various types of literature reviews based largely on the type of literature sourced ( Cronin et al. 2008 ). These include systematic literature reviews, traditional, narrative and integrative literature reviews ( Snyder, 2019 ). Aveyard and Bradbury-Jones (2019) found more than 35 commonly used terms to describe literature reviews. Within healthcare, systematic literature reviews initially gained traction and widespread support because of their reproducibility and focus on arriving at evidence-based conclusions that could influence practice and policy development ( Boell and Cecez-Kecmanovic, 2015 ). Yet, it became apparent that healthcare-related treatment options needed to review broader spectrums of research for treatment options to be considered comprehensive, holistic and patient orientated ( Boell and Cecez-Kecmanovic, 2015 ). Stern et al. (2014) suggest that despite the focus in healthcare on quantitative research not all pertinent questions surrounding the provision of care can be answered from this approach. To devise solutions to multidimensional problems, all forms of trustworthy evidence need to be considered ( Stern et al. 2014 ).

Integrative reviews assimilate research data from various research designs to reach conclusions that are comprehensive and reliable ( Soares et al. 2014 ). For example, an integrative review considers both qualitative and quantitative research to reach its conclusions. This approach promotes the development of a comprehensive understanding of the topic from a synthesis of all forms of available evidence ( Russell, 2005 ; Torraco, 2005 ). The strengths of an integrative review include its capacity to analyse research literature, evaluate the quality of the evidence, identify knowledge gaps, amalgamate research from various research designs, generate research questions and develop theoretical frameworks ( Russell, 2005 ). Aveyard and Bradbury-Jones (2019) suggested that integrative reviews exhibit similar characteristics to systematic reviews and may therefore be regarded as rigorous.

Integrative reviews value both qualitative and quantitative research which are built upon differing epistemological paradigms. Both types of research are vital in developing the evidence base that guides healthcare provision ( Leppäkoski and Paavilainen, 2012 ). Therefore, integrative reviews may influence policy development as their conclusions have considered a broad range of appropriate literature ( Whittemore and Knafl, 2005 ). An integrative approach to evidence synthesis allows healthcare professionals to make better use of all available evidence and apply it to the clinical practice environment ( Souza et al. 2010 ). For example, Aveyard and Bradbury-Jones (2019) found in excess of 12 different types of reviews employed to guide healthcare practice. The healthcare profession requires both quantitative and qualitative forms of research to establish the robust evidence base that enables the provision of evidence-based patient-orientated healthcare.

Integrative reviews require a specific set of skills to identify and synthesise literature ( Boell and Cecez-Kecmanovic, 2010 ). There remains a paucity of literature that provides explicit guidance to novice nursing researchers on how to conduct an integrative review and importantly how to ensure the results and conclusions are both comprehensive and reliable. Furthermore, novice nursing researchers may receive little formal training to develop the skills required to generate a comprehensive integrative review ( Boote and Beile, 2005 ). Aveyard and Bradbury-Jones (2019) also emphasised the limited literature providing guidance surrounding integrative reviews. Therefore, novice nursing researchers need to rely on published guidance to assist them. In this regard this paper, using an integrative review conducted by the authors as a case study, aims to provide a framework for novice nursing researchers conducting integrative reviews.

Developing the framework

In conducting integrative reviews, the novice nursing researcher may need to employ a framework to ensure the findings are comprehensive and reliable ( Boell and Cecez-Kecmanovic, 2010 ; Snyder, 2019 ). A framework to guide novice nursing researchers in conducting integrative reviews has been adapted by the authors and will now be described and delineated. This framework used various published literature to guide its creation, namely works by Aveyard and Bradbury-Jones (2019) , Nelson (2014), Stern et al. (2014) , Whittemore and Knafl (2005) , Pluye et al. (2009) , Moher et al., (2009) and Attride-Stirling, (2001) . The suggested framework involves seven steps ( Figure 1 ).

Integrative review framework ( Cooke et al. 2012 ; Riva et al. 2012 ).

Step 1: Write the review question

The review question acts as a foundation for an integrative study ( Riva et al. 2012 ). Yet, a review question may be difficult to articulate for the novice nursing researcher as it needs to consider multiple factors specifically, the population or sample, the interventions or area under investigation, the research design and outcomes and any benefit to the treatment ( Riva et al. 2012 ). A well-written review question aids the researcher to develop their research protocol/design and is of vital importance when writing an integrative review.

To articulate a review question there are numerous tools available to the novice nursing researcher to employ. These tools include variations on the PICOTs template (PICOT, PICO, PIO), and the Spider template. The PICOTs template is an established tool for structuring a research question. Yet, the SPIDER template has gained acceptance despite the need for further research to determine its applicability to multiple research contexts ( Cooke et al., 2012 ). Templates are recommended to aid the novice nursing researcher in effectively delineating and deconstructing the various elements within their review question. Delineation aids the researcher to refine the question and produce more targeted results within a literature search. In the case study, the review question was to: identify, evaluate and synthesise current knowledge and healthcare approaches to women presenting due to intimate partner violence (IPV) within emergency departments (ED). This review objective is delineated in the review question templates shown in Table 1 .

( Cooke et al. 2012 ; Riva et al. 2012 ).

Step 2: Determine the search strategy

In determining a search strategy, it is important for the novice nursing researcher to consider the databases employed, the search terms, the Boolean operators, the use of truncation and the use of subject headings. Furthermore, Nelson (2014) suggests that a detailed description of the search strategy should be included within integrative reviews to ensure readers are able to reproduce the results.

The databases employed within a search strategy need to consider the research aim and the scope of information contained within the database. Many databases vary in their coverage of specific journals and associated literature, such as conference proceedings ( Boell and Cecez-Kecmanovic, 2010 ). Therefore, the novice nursing researcher should consult several databases when conducting their searches. For example, search strategies within the healthcare field may utilise databases such as Cumulative Index to Nursing and Allied Healthcare Literature (CINAHL), Cochrane Library, Science Direct, ProQuest, Web of Science, Scopus and PsychInfo ( Cronin et al. 2008 ). These databases among others are largely considered appropriate repositories of reliable data that novice researchers may utilise when researching within healthcare. The date in which the searches are undertaken should be within the search strategy as searches undertaken after this date may generate increased results in line with the publication of further studies.

Utilising an established template to generate a research question allows for the delineation of key elements within the question as seen above. These key elements may assist the novice nursing researcher in determining the search terms they employ. Furthermore, keywords on published papers may provide the novice nursing researcher with alternative search terms, synonyms and introduce the researcher to key terminology employed within their field ( Boell and Cecez-Kecmanovic, 2010 ). For example, within the case study undertaken the search terms included among others: ‘domestic violence’, ‘domestic abuse’, ‘intimate partner violence and/or abuse’. To refine the search to the correct healthcare environment the terms ‘emergency department’ and/or ‘emergency room’ were employed. To link search terms, the researcher should consider their use of Boolean operators ‘And’ ‘Or’ and ‘Not’ and their use of truncation ( Cronin et al. 2008 ). Truncation is the shortening of words which in literature searches may increase the number of search results. Medical subject headings (MeSH) or general subject headings should be employed where appropriate and within this case study the headings included ‘nursing’, ‘domestic violence’ and ‘intimate partner violence’.

Inclusion and exclusion criteria allow the novice nursing researcher to reduce and refine the search parameters and locate the specific data they seek. Appropriate use of inclusion and exclusion criteria permits relevant data to be sourced as wider searches can produce a large amount of disparate data, whereas a search that is too narrow may result in the omission of significant findings ( Boell and Cecez-Kecmanovic, 2010 ). The novice nursing researcher needs to be aware that generating a large volume of search results may not necessarily result in relevant data being identified. Within integrative reviews there is potential for a large volume of data to be sourced and therefore time and resources required to complete the review need to be considered ( Heyvaert et al. 2017 ). The analysis and refining of a large volume of data can become a labour-intensive exercise for the novice nursing researcher ( Boell and Cecez-Kecmanovic, 2010 ).

Stern et al. (2014) suggest various elements that should be considered within inclusion/exclusion criteria:

• the type of studies included;
• the topic under exploration;
• the outcomes;
• publication language;
• the time period; and
• the methods employed.

The use of limiters or exclusion criteria are an effective method to manage the amount of time it takes to undertake searches and limit the volume of research generated. Yet, exclusion criteria may introduce biases in the search results and should therefore be used with caution and to produce specific outcomes by the novice nursing researcher ( Hammerstrøm et al. 2017 ).

Whittemore and Knafl (2005) suggest that randomised controlled trials, prospective and retrospective cohort studies, case control studies, cross sectional studies, systematic reviews and meta-analyses should all be included within the search strategy. Therefore, there are no biases based on the type of publication sourced ( Hammerstrøm et al. 2017 ).

There should be no restriction on the sample size within the studies recognising that qualitative studies generally have smaller sample sizes, and to capture the breadth of research available. There was no restriction on the date of publication within the case study as quality literature was limited. Scoping widely is an important strategy within integrative reviews to produce comprehensive results. A manual citation search of the reference list of all sourced papers was also undertaken by a member of the research team.

Literature may be excluded if those papers were published in a language foreign to the researcher with no accepted translation available. Though limiting papers based on translation availability may introduce some bias, this does ensure the review remains free from translational errors and cultural misinterpretations. In the case study, research conducted in developing countries with a markedly different healthcare service and significant resource limitations were excluded due to their lack of generalisability and clinical relevance; though this may have introduced a degree of location bias ( Nelson, 2014 ).

A peer review of the search strategy by an individual who specialises in research data searches such as a research librarian may be a viable method in which the novice healthcare researcher can ensure the search strategy is appropriate and able to generate the required data. One such tool that a novice nurse may employ is the Peer Review of the Search Strategy (PRESS) checklist. A peer review of the caste study was undertaken by a research librarian. All recommendations were incorporated into the search strategy which included removing a full text limiter, and changes to the Boolean and proximity operators.

After the search strategy has been implemented the researcher removes duplicate results and screened the retrieved publications based on their titles and abstracts. A second screening was then undertaken based on the full text of retrieved publications to remove papers that were irrelevant to the research question. Full text copies should then be obtained for critical appraisal employing validated methods.

Step 3: Critical appraisal of search results

The papers identified within the search strategy should undergo a critical appraisal to determine if they are appropriate and of sufficient quality to be included within the review. This should be conducted or reviewed by a second member of the research team, which occurred within this case study. Any discrepancies were discussed until consensus was achieved. A critical appraisal allows the novice healthcare researcher to appraise the relevance and trustworthiness of a study and, therefore, determine its applicability to their research (CASP, 2013). There are several established tools a novice nurse can employ in which to structure their critical appraisal. These include the Scoring System for Mixed-Methods Research and Mixed Studies Reviews developed by Pluye et al. (2009) and the Critical Appraisal Skills Programme (CASP, 2018) Checklists.

The review undertaken by the authors employed the scoring system for mixed-methods research and mixed-studies reviews developed by Pluye et al. (2009) . This scoring system was specifically designed for reviews employing studies from various research designs and therefore was utilised with ease ( Table 2 ).

The scoring system for mixed-methods research and mixed-studies reviews ( Pluye et al. 2009 ).

Using the CASP checklist aids the novice nursing researcher to examine the methodology of identified papers to establish validity. This critical appraisal tool contains 10 items. These items are yes or no questions that assist the researcher to determine (a) if the results of the paper are valid, (b) what the results are and (c) if it is relevant in the context of their study. For example, the checklist asks the researcher to consider the presence of a clear statement surrounding the aims of the research, and to consider why and how the research is important in regard to their topic (CASP, 2013). This checklist supports the nurse researcher to assess the validity, results and significance of research, and therefore appropriately decide on its inclusion within the review ( Krainovich-Miller et al., 2009 ).

Step 4: Summarise the search results

A summary of the results generated by literature searches is important to exemplify how comprehensive the literature is or conversely to identify if there are gaps in research. This summary should include the number of, and type of papers included within the review post limiters, screening and critical appraisal of search results. For example, within the review detailed throughout this paper the search strategy resulted in the inclusion of 25 qualitative and six quantitative papers ( Bakon et al. 2019 ). Many papers provide a summary of their search results visually in a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram ( Boell and Cecez-Kecmanovic, 2015 ). PRISMA is a method of reporting that enables readers to assess the robustness of the results ( Leclercq et al. 2019 ; Moher et al. 2009 ). PRISMA promotes the transparency of the search process by delineating various items within the search process ( Leclercq et al. 2019 ; Moher et al. 2009 ). Researchers may decide how rigorously they follow this process yet should provide a rationale for any deviations ( Leclercq et al. 2019 ; Moher et al, 2009 ). Figure 2 is an example of the PRISMA flow diagram as it was applied within the case study.

Example PRISMA flow diagram ( Bakon et al. 2019 ; Moher et al. 2009 ).

Step 5: Data extraction and reduction

Data can be extracted from the critically appraised papers identified through the search strategy employing extraction tables. Within the case study data were clearly delineated, as suggested by Boell and Cecez-Kecmanovic (2010) , into extraction or comparison tables ( Table 3 ). These tables specify the authors, the date of publication, year of publication, site where the research was conducted and the key findings. Setting out the data into tables facilitates the comparison of these variables and aids the researcher to determine the appropriateness of the papers’ inclusion or exclusion within the review ( Whittemore and Knafl, 2005 ).

Step 6: Analysis

Thematic analysis is widely used in integrative research ( Attride-Stirling, 2001 ). In this section we will discuss the benefits of employing a structured approach to thematic analysis including the formation of a thematic network. A thematic network is a visual diagram or depiction of the themes displaying their interconnectivity. Thematic analysis with the development of a thematic network is a way of identifying themes at various levels and depicting the observed relationships and organisation of these themes ( Attride-Stirling, 2001 ). There are numerous methods and tools available in which to conduct a thematic analysis that may be of use to the novice healthcare researcher conducting an integrative review. The approach used in a thematic analysis is important though a cursory glance at many literature reviews will reveal that many authors do not delineate the methods they employ. This includes the thematic analysis approach suggested by Thomas and Harden (2008) and the approach to thematic networking suggested by Attride-Stirling (2001) .

Thomas and Harden (2008) espouse a three-step approach to thematic analysis which includes: (a) coding, (b) organisation of codes into descriptive themes, and (c) the amalgamation of descriptive themes into analytical themes. The benefit of this approach lies in its simplicity and the ease with which a novice nurse researcher can apply the required steps. In contrast, the benefit of the approach suggested by Attride-Stirling (2001) lies in its ability to move beyond analysis and generate a visual thematic network which facilitates a critical interpretation and synthesis of the data.

Thematic networks typically depict three levels: basic themes, organising themes and global themes ( Attride-Stirling, 2001 ). The thematic network can then be developed. A thematic network is a visual depiction that appears graphically as a web like design ( Attride-Stirling, 2001 ). Thematic networks emphasise the relationships and interconnectivity of the network. It is an illustrative tool that facilitates interpretation of the data ( Attride-Stirling, 2001 ).

The benefits of employing a thematic analysis and networking within integrative reviews is the flexibility inherent within the approach, which allows the novice nursing researcher to provide a comprehensive accounting of the data ( Nowell et al. 2017 ). Thematic analysis is also an easily grasped form of data analysis that is useful for exploring various perspectives on specific topics and highlighting knowledge gaps ( Nowell et al. 2017 ). Thematic analysis and networking is also useful as a method to summarise large or diversified data sets to produce insightful conclusions ( Attride-Stirling, 2001 ; Nowell et al. 2017 ). The ability to assimilate data from various seemingly disparate perspectives may be challenging for the novice nursing researcher conducting an integrative review yet this integration of data by thematic analysis and networking was is integral.

To ensure the trustworthiness of results, novice nursing researchers need to clearly articulate each stage within the chosen method of data analysis ( Attride-Stirling, 2001 ; Nowell et al. 2017 ). The method employed in data analysis needs to be precise and exhaustively delineated ( Attride-Stirling, 2001 ; Nowell et al. 2017 ). Attride-Stirling (2001) suggests six steps within her methods of thematic analysis and networking. These steps include:

• code material;
• identify themes;
• construct thematic network;
• describe and explore the thematic network;
• summarise thematic network findings; and
• interpret patterns to identify implications.

In employing the approach suggested by Attride-Stirling (2001) within the case study the coding of specific findings within the data permitted the development of various themes ( Table 4 ). Inclusion of both quantitative and qualitative findings within the themes facilitated integration of the data which identified patterns and generated insights into the current care provided to IPV victims within ED.

Coding and theme formation.

Step 7: Conclusions and implications

A conclusion is important to remind the reader why the research topic is important. The researcher can then follow advice by Higginbottom (2015) who suggests that in drawing and writing research conclusions the researcher has an opportunity to explain the significance of the findings. The researcher may also need to explain these conclusions in light of the study limitations and parameters. Higginbottom (2015) emphasises that a conclusion is not a summary or reiteration of the results but a section which details the broader implications of the research and translates this knowledge into a format that is of use to the reader. The implications of the review findings for healthcare practice, for healthcare education and research should be considered.

Employing this structured and comprehensive framework within the case study the authors were able to determine that there remains a marked barrier in the provision of healthcare within the ED to women presenting with IPV-related injury. By employing an integrative approach multiple forms of literature were reviewed, and a considerable gap was identified. Therefore, further research may need to focus on the developing a structured healthcare protocol to aid ED clinicians to meet the needs of this vulnerable patient population.

Integrative reviews can be conducted with success when they follow a structured approach. This paper proposes a framework that novice nursing researchers can employ. Applying our stepped framework within an integrative review will strengthen the robustness of the study and facilitate its translation into policy and practice. This framework was employed by the authors to identify, evaluate and synthesise current knowledge and approaches of health professionals surrounding the care provision of women presenting due to IPV within emergency departments. The recommendations from the case study are currently being translated and implemented into the practice environment.

Key points for policy, practice and/or research

• Integrative literature reviews are required within nursing to consider elements of care provision from a holistic perspective.
• There is currently limited literature providing explicit guidance on how to undertake an integrative literature review.
• Clear delineation of the integrative literature review process demonstrates how the knowledge base was understood, organised and analysed.
• Nurse researchers may utilise this guidance to ensure the reliability of their integrative review.

Nursing: How to Write a Literature Review

• Traditional or Narrative Literature Review

Getting started

1. start with your research question, 2. search the literature, 3. read & evaluate, 4. finalize results, 5. write & revise, brainfuse online tutoring and writing review.

• RESEARCH HELP

The best way to approach your literature review is to break it down into steps.  Remember, research is an iterative process, not a linear one.  You will revisit steps and revise along the way.  Get started with the handout, information, and tips from various university Writing Centers below that provides an excellent overview.  Then move on to the specific steps recommended on this page.

• UNC- Chapel Hill Writing Center Literature Review Handout, from the University of North Carolina at Chapel Hill.
• University of Wisconsin-Madison Writing Center Learn how to write a review of literature, from the University of Wisconsin-Madison.
• University of Toronto-- Writing Advice The Literature Review: A few tips on conducting it, from the University of Toronto.
• Begin with a topic.
• Understand the topic. 
• Familiarize yourself with the terminology.  Note what words are being used and keep track of these for use as database search keywords. 
• See what research has been done on this topic before you commit to the topic.  Review articles can be helpful to understand what research has been done .
• Develop your research question.  (see handout below)
• How comprehensive should it be? 
• Is it for a course assignment or a dissertation? 
• How many years should it cover?
• Developing a good nursing research question Handout. Reviews PICO method and provides search tips.

Your next step is to construct a search strategy and then locate & retrieve articles.

•  There are often 2-4 key concepts in a research question.
• Search for primary sources (original research articles.)
• These are based on the key concepts in your research question.
• Remember to consider synonyms and related terms.
• Which databases to search?
• What limiters should be applied (peer-reviewed, publication date, geographic location, etc.)?

Review articles (secondary sources)

Use to identify literature on your topic, the way you would use a bibliography.  Then locate and retrieve the original studies discussed in the review article. Review articles are considered secondary sources.

• Once you have some relevant articles, review reference lists to see if there are any useful articles.
• Which articles were written later and have cited some of your useful articles?  Are these, in turn, articles that will be useful to you? 
• Keep track of what terms you used and what databases you searched. 
• Use database tools such as save search history in EBSCO to help.
• Keep track of the citations for the articles you will be using in your literature review. 
• Use RefWorks or another method of tracking this information. 
• Database Search Strategy Worksheet Handout. How to construct a search.
• TUTORIAL: How to do a search based on your research question This is a self-paced, interactive tutorial that reviews how to construct and perform a database search in CINAHL.

The next step is to read, review, and understand the articles.

• Start by reviewing abstracts. 
• Make sure you are selecting primary sources (original research articles).
• Note any keywords authors report using when searching for prior studies.
• You will need to evaluate and critique them and write a synthesis related to your research question.
• Consider using a matrix to organize and compare and contrast the articles . 
• Which authors are conducting research in this area?  Search by author.  
• Are there certain authors’ whose work is cited in many of your articles?  Did they write an early, seminal article that is often cited?
• Searching is a cyclical process where you will run searches, review results, modify searches, run again, review again, etc. 
• Critique articles.  Keep or exclude based on whether they are relevant to your research question.
• When you have done a thorough search using several databases plus Google Scholar, using appropriate keywords or subject terms, plus author’s names, and you begin to find the same articles over and over.
• Remember to consider the scope of your project and the length of your paper.  A dissertation will have a more exhaustive literature review than an 8 page paper, for example.
• What are common findings among each group or where do they disagree? 
• Identify common themes. Identify controversial or problematic areas in the research. 
• Use your matrix to organize this.
• Once you have read and re-read your articles and organized your findings, you are ready to begin the process of writing the literature review.

2. Synthesize.  (see handout below)

• Include a synthesis of the articles you have chosen for your literature review.
• A literature review is NOT a list or a summary of what has been written on a particular topic. 
• It analyzes the articles in terms of how they relate to your research question. 
• While reading, look for similarities and differences (compare and contrast) among the articles.  You will create your synthesis from this.
• Synthesis Examples Handout. Sample excerpts that illustrate synthesis.

Literature Review Overview

What is a Literature Review? Why Are They Important?

A literature review is important because it presents the "state of the science" or accumulated knowledge on a specific topic. It summarizes, analyzes, and compares the available research, reporting study strengths and weaknesses, results, gaps in the research, conclusions, and authors’ interpretations.

Tips and techniques for conducting a literature review are described more fully in the subsequent boxes:

• Literature review steps

• Literature reviews sections
• In-depth resources to assist in writing a literature review
• Templates to start your review

Literature Review Steps

Graphic used with permission: Torres, E. Librarian, Hawai'i Pacific University

1. Choose a topic and define your research question

• Try to choose a topic of interest. You will be working with this subject for several weeks to months.
• Ideas for topics can be found by scanning medical news sources (e.g MedPage Today), journals / magazines, work experiences, interesting patient cases, or family or personal health issues.
• Do a bit of background reading on topic ideas to familiarize yourself with terminology and issues. Note the words and terms that are used.
• Develop a focused research question using PICO(T) or other framework (FINER, SPICE, etc - there are many options) to help guide you.
• Run a few sample database searches to make sure your research question is not too broad or too narrow.
• If possible, discuss your topic with your professor. 

2. Determine the scope of your review

The scope of your review will be determined by your professor during your program. Check your assignment requirements for parameters for the Literature Review.

• How many studies will you need to include?
• How many years should it cover? (usually 5-7 depending on the professor)
• For the nurses, are you required to limit to nursing literature?

3. Develop a search plan

• Determine which databases to search. This will depend on your topic. If you are not sure, check your program specific library website (Physician Asst / Nursing / Health Services Admin) for recommendations.
• Create an initial search string using the main concepts from your research (PICO, etc) question. Include synonyms and related words connected by Boolean operators
• Contact your librarian for assistance, if needed.

4. Conduct searches and find relevant literature

• Keep notes as you search - tracking keywords and search strings used in each database in order to avoid wasting time duplicating a search that has already been tried
• Read abstracts and write down new terms to search as you find them
• Check MeSH or other subject headings listed in relevant articles for additional search terms
• Scan author provided keywords if available
• Check the references of relevant articles looking for other useful articles (ancestry searching)
• Check articles that have cited your relevant article for more useful articles (descendancy searching). Both PubMed and CINAHL offer Cited By links
• Revise the search to broaden or narrow your topic focus as you peruse the available literature
• Conducting a literature search is a repetitive process. Searches can be revised and re-run multiple times during the process.
• Track the citations for your relevant articles in a software citation manager such as RefWorks, Zotero, or Mendeley

5. Review the literature

• Read the full articles. Do not rely solely on the abstracts. Authors frequently cannot include all results within the confines of an abstract. Exclude articles that do not address your research question.
• While reading, note research findings relevant to your project and summarize. Are the findings conflicting? There are matrices available than can help with organization. See the Organizing Information box below.
• Critique / evaluate the quality of the articles, and record your findings in your matrix or summary table. Tools are available to prompt you what to look for. (See Resources for Appraising a Research Study box on the HSA, Nursing , and PA guides )
• You may need to revise your search and re-run it based on your findings.

6. Organize and synthesize

• Compile the findings and analysis from each resource into a single narrative.
• Using an outline can be helpful. Start broad, addressing the overall findings and then narrow, discussing each resource and how it relates to your question and to the other resources.
• Cite as you write to keep sources organized.
• Write in structured paragraphs using topic sentences and transition words to draw connections, comparisons, and contrasts.
• Don't present one study after another, but rather relate one study's findings to another. Speak to how the studies are connected and how they relate to your work.

Organizing Information

Options to assist in organizing sources and information :

1. Synthesis Matrix

• helps provide overview of the literature
• information from individual sources is entered into a grid to enable writers to discern patterns and themes
• article summary, analysis, or results
• thoughts, reflections, or issues
• each reference gets its own row
• mind maps, concept maps, flowcharts
• at top of page record PICO or research question
• record major concepts / themes from literature
• list concepts that branch out from major concepts underneath - keep going downward hierarchically, until most specific ideas are recorded
• enclose concepts in circles and connect the concept with lines - add brief explanation as needed

3. Summary Table

• information is recorded in a grid to help with recall and sorting information when writing
• allows comparing and contrasting individual studies easily
• purpose of study
• methodology (study population, data collection tool)

Efron, S. E., & Ravid, R. (2019). Writing the literature review : A practical guide . Guilford Press.

Literature Review Sections

• Lit reviews can be part of a larger paper / research study or they can be the focus of the paper
• Lit reviews focus on research studies to provide evidence
• New topics may not have much that has been published

* The sections included may depend on the purpose of the literature review (standalone paper or section within a research paper)

Standalone Literature Review (aka Narrative Review):

• presents your topic or PICO question
• includes the why of the literature review and your goals for the review.
• provides background for your the topic and previews the key points
• Narrative Reviews: tmay not have an explanation of methods.
• include where the search was conducted (which databases) what subject terms or keywords were used, and any limits or filters that were applied and why - this will help others re-create the search
• describe how studies were analyzed for inclusion or exclusion
• review the purpose and answer the research question
• thematically - using recurring themes in the literature
• chronologically - present the development of the topic over time
• methodological - compare and contrast findings based on various methodologies used to research the topic (e.g. qualitative vs quantitative, etc.)
• theoretical - organized content based on various theories
• provide an overview of the main points of each source then synthesize the findings into a coherent summary of the whole
• present common themes among the studies
• compare and contrast the various study results
• interpret the results and address the implications of the findings
• do the results support the original hypothesis or conflict with it
• provide your own analysis and interpretation (eg. discuss the significance of findings; evaluate the strengths and weaknesses of the studies, noting any problems)
• discuss common and unusual patterns and offer explanations
•  stay away from opinions, personal biases and unsupported recommendations
• summarize the key findings and relate them back to your PICO/research question
• note gaps in the research and suggest areas for further research
• this section should not contain "new" information that had not been previously discussed in one of the sections above
• provide a list of all the studies and other sources used in proper APA 7

Literature Review as Part of a Research Study Manuscript:

• Compares the study with other research and includes how a study fills a gap in the research.
• Focus on the body of the review which includes the synthesized Findings and Discussion

Literature Reviews vs Systematic Reviews

Systematic Reviews are NOT the same as a Literature Review:

Literature Reviews:

• Literature reviews may or may not follow strict systematic methods to find, select, and analyze articles, but rather they selectively and broadly review the literature on a topic
• Research included in a Literature Review can be "cherry-picked" and therefore, can be very subjective

Systematic Reviews:

• Systemic reviews are designed to provide a comprehensive summary of the evidence for a focused research question
• rigorous and strictly structured, using standardized reporting guidelines (e.g. PRISMA, see link below)
• uses exhaustive, systematic searches of all relevant databases
• best practice dictates search strategies are peer reviewed
• uses predetermined study inclusion and exclusion criteria in order to minimize bias
• aims to capture and synthesize all literature (including unpublished research - grey literature) that meet the predefined criteria on a focused topic resulting in high quality evidence

Literature Review Examples

• Breastfeeding initiation and support: A literature review of what women value and the impact of early discharge (2017). Women and Birth : Journal of the Australian College of Midwives
• Community-based participatory research to promote healthy diet and nutrition and prevent and control obesity among African-Americans: A literature review (2017). Journal of Racial and Ethnic Health Disparities

• Vitamin D deficiency in individuals with a spinal cord injury: A literature review (2017). Spinal Cord

Systematic reviews provide a synthesis of evidence for a specific topic of interest, summarising the results of multiple studies to aid in clinical decisions and resource allocation. They remain among the best forms of evidence, and reduce the bias inherent in other methods. A solid understanding of the systematic review process can be of benefit to nurses that carry out such reviews, and for those who make decisions based on them. An overview of the main steps involved in carrying out a systematic review is presented, including some of the common tools and frameworks utilised in this area. This should provide a good starting point for those that are considering embarking on such work, and to aid readers of such reviews in their understanding of the main review components, in order to appraise the quality of a review that may be used to inform subsequent clinical decision making.

Since their inception in the late 1970s, systematic reviews have gained influence in the health professions ( Hanley and Cutts, 2013 ). Systematic reviews and meta-analyses are considered to be the most credible and authoritative sources of evidence available ( Cognetti et al, 2015 ) and are regarded as the pinnacle of evidence in the various ‘hierarchies of evidence’. Reviews published in the Cochrane Library ( https://www.cochranelibrary.com) are widely considered to be the ‘gold’ standard. Since Guyatt et al (1995) presented a users' guide to medical literature for the Evidence-Based Medicine Working Group, various hierarchies of evidence have been proposed. Figure 1 illustrates an example.

Systematic reviews can be qualitative or quantitative. One of the criticisms levelled at hierarchies such as these is that qualitative research is often positioned towards or even is at the bottom of the pyramid, thus implying that it is of little evidential value. This may be because of traditional issues concerning the quality of some qualitative work, although it is now widely recognised that both quantitative and qualitative research methodologies have a valuable part to play in answering research questions, which is reflected by the National Institute for Health and Care Excellence (NICE) information concerning methods for developing public health guidance. The NICE (2012) guidance highlights how both qualitative and quantitative study designs can be used to answer different research questions. In a revised version of the hierarchy-of-evidence pyramid, the systematic review is considered as the lens through which the evidence is viewed, rather than being at the top of the pyramid ( Murad et al, 2016 ).

Both quantitative and qualitative research methodologies are sometimes combined in a single review. According to the Cochrane review handbook ( Higgins and Green, 2011 ), regardless of type, reviews should contain certain features, including:

• Clearly stated objectives
• Predefined eligibility criteria for inclusion or exclusion of studies in the review
• A reproducible and clearly stated methodology
• Validity assessment of included studies (eg quality, risk, bias etc).

The main stages of carrying out a systematic review are summarised in Box 1 .

Formulating the research question

Before undertaking a systemic review, a research question should first be formulated ( Bashir and Conlon, 2018 ). There are a number of tools/frameworks ( Table 1 ) to support this process, including the PICO/PICOS, PEO and SPIDER criteria ( Bowers et al, 2011 ). These frameworks are designed to help break down the question into relevant subcomponents and map them to concepts, in order to derive a formalised search criterion ( Methley et al, 2014 ). This stage is essential for finding literature relevant to the question ( Jahan et al, 2016 ).

It is advisable to first check that the review you plan to carry out has not already been undertaken. You can optionally register your review with an international register of prospective reviews called PROSPERO, although this is not essential for publication. This is done to help you and others to locate work and see what reviews have already been carried out in the same area. It also prevents needless duplication and instead encourages building on existing work ( Bashir and Conlon, 2018 ).

A study ( Methley et al, 2014 ) that compared PICO, PICOS and SPIDER in relation to sensitivity and specificity recommended that the PICO tool be used for a comprehensive search and the PICOS tool when time/resources are limited.

The use of the SPIDER tool was not recommended due to the risk of missing relevant papers. It was, however, found to increase specificity.

These tools/frameworks can help those carrying out reviews to structure research questions and define key concepts in order to efficiently identify relevant literature and summarise the main objective of the review ( Jahan et al, 2016 ). A possible research question could be: Is paracetamol of benefit to people who have just had an operation? The following examples highlight how using a framework may help to refine the question:

• What form of paracetamol? (eg, oral/intravenous/suppository)
• Is the dosage important?
• What is the patient population? (eg, children, adults, Europeans)
• What type of operation? (eg, tonsillectomy, appendectomy)
• What does benefit mean? (eg, reduce post-operative pyrexia, analgesia).

An example of a more refined research question could be: Is oral paracetamol effective in reducing pain following cardiac surgery for adult patients? A number of concepts for each element will need to be specified. There will also be a number of synonyms for these concepts ( Table 2 ).

Table 2 shows an example of concepts used to define a search strategy using the PICO statement. It is easy to see even with this dummy example that there are many concepts that require mapping and much thought required to capture ‘good’ search criteria. Consideration should be given to the various terms to describe the heart, such as cardiac, cardiothoracic, myocardial, myocardium, etc, and the different names used for drugs, such as the equivalent name used for paracetamol in other countries and regions, as well as the various brand names. Defining good search criteria is an important skill that requires a lot of practice. A high-quality review gives details of the search criteria that enables the reader to understand how the authors came up with the criteria. A specific, well-defined search criterion also aids in the reproducibility of a review.

Search criteria

Before the search for papers and other documents can begin it is important to explicitly define the eligibility criteria to determine whether a source is relevant to the review ( Hanley and Cutts, 2013 ). There are a number of database sources that are searched for medical/health literature including those shown in Table 3 .

The various databases can be searched using common Boolean operators to combine or exclude search terms (ie AND, OR, NOT) ( Figure 2 ).

Although most literature databases use similar operators, it is necessary to view the individual database guides, because there are key differences between some of them. Table 4 details some of the common operators and wildcards used in the databases for searching. When developing a search criteria, it is a good idea to check concepts against synonyms, as well as abbreviations, acronyms and plural and singular variations ( Cognetti et al, 2015 ). Reading some key papers in the area and paying attention to the key words they use and other terms used in the abstract, and looking through the reference lists/bibliographies of papers, can also help to ensure that you incorporate relevant terms. Medical Subject Headings (MeSH) that are used by the National Library of Medicine (NLM) ( https://www.nlm.nih.gov/mesh/meshhome.html) to provide hierarchical biomedical index terms for NLM databases (Medline and PubMed) should also be explored and included in relevant search strategies.

Searching the ‘grey literature’ is also an important factor in reducing publication bias. It is often the case that only studies with positive results and statistical significance are published. This creates a certain bias inherent in the published literature. This bias can, to some degree, be mitigated by the inclusion of results from the so-called grey literature, including unpublished work, abstracts, conference proceedings and PhD theses ( Higgins and Green, 2011 ; Bettany-Saltikov, 2012 ; Cognetti et al, 2015 ). Biases in a systematic review can lead to overestimating or underestimating the results ( Jahan et al, 2016 ).

An example search strategy from a published review looking at web use for the appraisal of physical health conditions can be seen in Box 2 . High-quality reviews usually detail which databases were searched and the number of items retrieved from each.

A balance between high recall and high precision is often required in order to produce the best results. An oversensitive search, or one prone to including too much noise, can mean missing important studies or producing too many search results ( Cognetti et al, 2015 ). Following a search, the exported citations can be added to citation management software (such as Mendeley or Endnote) and duplicates removed.

Title and abstract screening

Initial screening begins with the title and abstracts of articles being read and included or excluded from the review based on their relevance. This is usually carried out by at least two researchers to reduce bias ( Bashir and Conlon, 2018 ). After screening any discrepancies in agreement should be resolved by discussion, or by an additional researcher casting the deciding vote ( Bashir and Conlon, 2018 ). Statistics for inter-rater reliability exist and can be reported, such as percentage of agreement or Cohen's kappa ( Box 3 ) for two reviewers and Fleiss' kappa for more than two reviewers. Agreement can depend on the background and knowledge of the researchers and the clarity of the inclusion and exclusion criteria. This highlights the importance of providing clear, well-defined criteria for inclusion that are easy for other researchers to follow.

Full-text review

Following title and abstract screening, the remaining articles/sources are screened in the same way, but this time the full texts are read in their entirety and included or excluded based on their relevance. Reasons for exclusion are usually recorded and reported. Extraction of the specific details of the studies can begin once the final set of papers is determined.

Data extraction

At this stage, the full-text papers are read and compared against the inclusion criteria of the review. Data extraction sheets are forms that are created to extract specific data about a study (12 Jahan et al, 2016 ) and ensure that data are extracted in a uniform and structured manner. Extraction sheets can differ between quantitative and qualitative reviews. For quantitative reviews they normally include details of the study's population, design, sample size, intervention, comparisons and outcomes ( Bettany-Saltikov, 2012 ; Mueller et al, 2017 ).

Quality appraisal

The quality of the studies used in the review should also be appraised. Caldwell et al (2005) discussed the need for a health research evaluation framework that could be used to evaluate both qualitative and quantitative work. The framework produced uses features common to both research methodologies, as well as those that differ ( Caldwell et al, 2005 ; Dixon-Woods et al, 2006 ). Figure 3 details the research critique framework. Other quality appraisal methods do exist, such as those presented in Box 4 . Quality appraisal can also be used to weight the evidence from studies. For example, more emphasis can be placed on the results of large randomised controlled trials (RCT) than one with a small sample size. The quality of a review can also be used as a factor for exclusion and can be specified in inclusion/exclusion criteria. Quality appraisal is an important step that needs to be undertaken before conclusions about the body of evidence can be made ( Sambunjak and Franic, 2012 ). It is also important to note that there is a difference between the quality of the research carried out in the studies and the quality of how those studies were reported ( Sambunjak and Franic, 2012 ).

The quality appraisal is different for qualitative and quantitative studies. With quantitative studies this usually focuses on their internal and external validity, such as how well the study has been designed and analysed, and the generalisability of its findings. Qualitative work, on the other hand, is often evaluated in terms of trustworthiness and authenticity, as well as how transferable the findings may be ( Bettany-Saltikov, 2012 ; Bashir and Conlon, 2018 ; Siddaway et al, 2019 ).

Reporting a review (the PRISMA statement)

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) provides a reporting structure for systematic reviews/meta-analysis, and consists of a checklist and diagram ( Figure 4 ). The stages of identifying potential papers/sources, screening by title and abstract, determining eligibility and final inclusion are detailed with the number of articles included/excluded at each stage. PRISMA diagrams are often included in systematic reviews to detail the number of papers included at each of the four main stages (identification, screening, eligibility and inclusion) of the review.

Data synthesis

The combined results of the screened studies can be analysed qualitatively by grouping them together under themes and subthemes, often referred to as meta-synthesis or meta-ethnography ( Siddaway et al, 2019 ). Sometimes this is not done and a summary of the literature found is presented instead. When the findings are synthesised, they are usually grouped into themes that were derived by noting commonality among the studies included. Inductive (bottom-up) thematic analysis is frequently used for such purposes and works by identifying themes (essentially repeating patterns) in the data, and can include a set of higher-level and related subthemes (Braun and Clarke, 2012). Thomas and Harden (2008) provide examples of the use of thematic synthesis in systematic reviews, and there is an excellent introduction to thematic analysis by Braun and Clarke (2012).

The results of the review should contain details on the search strategy used (including search terms), the databases searched (and the number of items retrieved), summaries of the studies included and an overall synthesis of the results ( Bettany-Saltikov, 2012 ). Finally, conclusions should be made about the results and the limitations of the studies included ( Jahan et al, 2016 ). Another method for synthesising data in a systematic review is a meta-analysis.

Limitations of systematic reviews

Apart from the many advantages and benefits to carrying out systematic reviews highlighted throughout this article, there remain a number of disadvantages. These include the fact that not all stages of the review process are followed rigorously or even at all in some cases. This can lead to poor quality reviews that are difficult or impossible to replicate. There also exist some barriers to the use of evidence produced by reviews, including ( Wallace et al, 2012 ):

• Lack of awareness and familiarity with reviews
• Lack of access
• Lack of direct usefulness/applicability.

Meta-analysis

When the methods used and the analysis are similar or the same, such as in some RCTs, the results can be synthesised using a statistical approach called meta-analysis and presented using summary visualisations such as forest plots (or blobbograms) ( Figure 5 ). This can be done only if the results can be combined in a meaningful way.

Meta-analysis can be carried out using common statistical and data science software, such as the cross-platform ‘R’ ( https://www.r-project.org), or by using standalone software, such as Review Manager (RevMan) produced by the Cochrane community ( https://tinyurl.com/revman-5), which is currently developing a cross-platform version RevMan Web.

Carrying out a systematic review is a time-consuming process, that on average takes between 6 and 18 months and requires skill from those involved. Ideally, several reviewers will work on a review to reduce bias. Experts such as librarians should be consulted and included where possible in review teams to leverage their expertise.

Systematic reviews should present the state of the art (most recent/up-to-date developments) concerning a specific topic and aim to be systematic and reproducible. Reproducibility is aided by transparent reporting of the various stages of a review using reporting frameworks such as PRISMA for standardisation. A high-quality review should present a summary of a specific topic to a high standard upon which other professionals can base subsequent care decisions that increase the quality of evidence-based clinical practice.

• Systematic reviews remain one of the most trusted sources of high-quality information from which to make clinical decisions
• Understanding the components of a review will help practitioners to better assess their quality
• Many formal frameworks exist to help structure and report reviews, the use of which is recommended for reproducibility
• Experts such as librarians can be included in the review team to help with the review process and improve its quality

CPD reflective questions

• Where should high-quality qualitative research sit regarding the hierarchies of evidence?
• What background and expertise should those conducting a systematic review have, and who should ideally be included in the team?
• Consider to what extent inter-rater agreement is important in the screening process

Good Place to Start: Citation Databases

Interdisciplinary Citation Databases:

A good place to start your research  is to search a research citation database to view the scope of literature available on your topic.

TIP #1: SEED ARTICLE Begin your research with a "seed article" - an article that strongly supports your research topic.  Then use a citation database to follow the studies published by finding articles which have cited that article, either because they support it or because they disagree with it.

TIP #2: SNOWBALLING Snowballing is the process where researchers will begin with a select number of articles they have identified relevant/strongly supports their topic and then search each articles' references reviewing the studies cited to determine if they are relevant to your research.

BONUS POINTS: This process also helps identify key highly cited authors within a topic to help establish the "experts" in the field.

Begin by constructing a focused research question to help you then convert it into an effective search strategy.

• Identify keywords or synonyms
• Type of study/resources
• Which database(s) to search
• Asking a Good Question (PICO)
• PICO - AHRQ
• PICO - Worksheet
• What Is a PICOT Question?

Seminal Works: Search Key Indexing/Citation Databases

• Google Scholar
• Web of Science

TIP – How to Locate Seminal Works

• DO NOT: Limit by date range or you might overlook the seminal works
• DO: Look at highly cited references (Seminal articles are frequently referred to “cited” in the research)
• DO: Search citation databases like Scopus, Web of Science and Google Scholar

What is a literature review?

A literature review is a comprehensive and up-to-date overview of published information on a subject area. Conducting a literature review demands a careful examination of a body of literature that has been published that helps answer your research question (See PICO). Literature reviewed includes scholarly journals, scholarly books, authoritative databases, primary sources and grey literature.

A literature review attempts to answer the following:

• What is known about the subject?
• What is the chronology of knowledge about my subject?
• Are there any gaps in the literature?
• Is there a consensus/debate on issues?
• Create a clear research question/statement
• Define the scope of the review include limitations (i.e. gender, age, location, nationality...)
• Search existing literature including classic works on your topic and grey literature
• Evaluate results and the evidence (Avoid discounting information that contradicts your research)
• Track and organize references
• How to conduct an effective literature search.
• Social Work Literature Review Guidelines (OWL Purdue Online Writing Lab)

What is PICO?

The PICO model can help you formulate a good clinical question. Sometimes it's referred to as PICO-T, containing an optional 5th factor.

The Scholarly Conversation

A literature review provides an overview of previous research on a topic that critically evaluates, classifies, and compares what has already been published on a particular topic. It allows the author to synthesize and place into context the research and scholarly literature relevant to the topic. It helps map the different approaches to a given question and reveals patterns. It forms the foundation for the author’s subsequent research and justifies the significance of the new investigation.

A literature review can be a short introductory section of a research article or a report or policy paper that focuses on recent research. Or, in the case of dissertations, theses, and review articles, it can be an extensive review of all relevant research.

• The format is usually a bibliographic essay; sources are briefly cited within the body of the essay, with full bibliographic citations at the end.
• The introduction should define the topic and set the context for the literature review. It will include the author's perspective or point of view on the topic, how they have defined the scope of the topic (including what's not included), and how the review will be organized. It can point out overall trends, conflicts in methodology or conclusions, and gaps in the research.
• In the body of the review, the author should organize the research into major topics and subtopics. These groupings may be by subject, (e.g., globalization of clothing manufacturing), type of research (e.g., case studies), methodology (e.g., qualitative), genre, chronology, or other common characteristics. Within these groups, the author can then discuss the merits of each article and analyze and compare the importance of each article to similar ones.
• The conclusion will summarize the main findings, make clear how this review of the literature supports (or not) the research to follow, and may point the direction for further research.
• The list of references will include full citations for all of the items mentioned in the literature review.

A literature review should try to answer questions such as

• Who are the key researchers on this topic?
• What has been the focus of the research efforts so far and what is the current status?
• How have certain studies built on prior studies? Where are the connections? Are there new interpretations of the research?
• Have there been any controversies or debate about the research? Is there consensus? Are there any contradictions?
• Which areas have been identified as needing further research? Have any pathways been suggested?
• How will your topic uniquely contribute to this body of knowledge?
• Which methodologies have researchers used and which appear to be the most productive?
• What sources of information or data were identified that might be useful to you?
• How does your particular topic fit into the larger context of what has already been done?
• How has the research that has already been done help frame your current investigation ?

Introduction to critical appraisal

Evidence-based nursing (EBN) means using the best available evidence from research, along with patient preferences and clinical experience, when making nursing decisions. 1 Nurses are increasingly concerned about ensuring that care is research based, and EBN offers a strategy to help nurses achieve this goal by using 5 steps:

Step 2: translating these areas of uncertainty into focused, searchable questions 2

Step 3: searching the literature for studies that use appropriate designs to help answer the question 3 – 6

Step 4: critically appraising the research

Step 5: changing practice if the research suggests this is necessary.

Previous Notebooks in Evidence-Based Nursing that have described the process of EBN 2 – 6 were written with busy clinical nurses in mind. The next series of Notebooks will explore step 4 in detail—how to assess whether research findings are valid and appropriate for clinical application.

The volume of healthcare literature has been described in graphic terms. Did you know, for example, that Medline has indexed more than 9 million citations in more than 4,000 journals since 1966? 7 Clearly, no individual practitioner can read this volume of research; nor should they try, as only a small proportion of it is of good quality. The trick to keeping abreast of the latest research is to quickly filter the good from the bad. For example, staff of the evidence-based journals office recently calculated that of 136 journals read for 4 evidence-based journals ( Evidence-Based Nursing , Evidence-Based Mental Health , Evidence-Based Medicine , and ACP Journal Club ), an estimated 8% of 21 100 articles passed evidence-based methodologic filters (personal communication, A McKibbon, 20 Mar 2000).

Anyone who has designed or implemented a research study knows that it can be difficult to do well. Researchers, like the rest of us, like to spread “news” and may exaggerate the importance and strength of the findings of their own research. The clinician is faced with the challenge of filtering the thousands of articles published each year into manageable information. This challenge is increased because researchers are notoriously bad at communicating in a language that is accessible to anybody other than researchers. It is not surprising that time and again, nurses tell researchers that they find it extremely difficult, if not impossible to use research findings in their practice.

But don't despair! EBN is possible because (1) there are now a number of clinical evidence sources which present appraised and summarised research for clinicians; (2) good search strategies can identify research that has used an appropriate design to answer your particular clinical question; and (3) critical appraisal is easy to learn, becomes easier with practice, and may be made easier with the Users' Guides series, which will appear in upcoming issues of Evidence-Based Nursing .

Sources of pre-appraised clinical evidence

Clinicians are no longer expected to fend for themselves when trying to deal with the huge volume of research literature. Systematic reviews, for example, are summaries of all the research on a particular topic. An international collaboration, the Cochrane Collaboration, produces and disseminates high quality systematic reviews, and even more importantly, keeps them up to date as new studies become available. The Cochrane Library (available on CD-ROM and via the Internet at http://hiru.mcmaster.ca/cochrane/cochrane/cdsr.htm ) is probably the most important source of reliable information about health care anywhere in the world. The Library contains systematic reviews prepared by Cochrane review groups and others, and a large database of clinical trials. 3

Journals such as Evidence-Based Nursing , Evidence-Based Mental Health , and Evidence-Based Medicine summarise the most valid and clinically applicable research selected from the international research literature. High quality studies and systematic reviews are identified using explicit methodologic criteria and then summarised in the form of structured abstracts. This approach differs from “current awareness” services, which serve to merely announce potentially interesting new research; evidence-based journals use an explicit, quality filtering process to identify only those studies of high methodologic quality. The structured abstracts provide a brief summary of the research question, study design, methods, and main results and the accompanying commentaries help us to interpret the study findings and to suggest how they might be applied in clinical practice.

Clinical Evidence is a new publication that produces and updates rigorous summaries of the research on many common conditions, including, for example, child health and wound care. 8

Sensitive and specific search strategies

Databases such as Medline and CINAHL provide electronic access to the healthcare literature, but they index letters, editorials, and general articles as well as primary studies and systematic reviews. Furthermore, high quality studies and reviews comprise an extremely small proportion of the indexed literature. The trick to searching these databases to find studies to answer your clinical questions lies in using search strategies that have maximum sensitivity (ie, identify a high proportion of the valid and relevant studies) and specificity (ie, do not identify many irrelevant studies). For example, the best single term Medline search to find studies that are likely to have used an appropriate design to evaluate a therapy or intervention is “clinical trial (publication type)”. 4 Of course, any primary studies identified through searches of Medline, CINAHL, or other databases must be appraised for validity and applicability using the critical appraisal techniques that will be addressed in the remainder of this users' guide and the series that follows.

Critical appraisal

Imagine that you have recently been promoted to a new role in your hospital and that you have responsibility for practice development on the medical wards. For the first time in your career you are able to set aside time in your week for reading and keeping abreast of new research—you think you have about 3 hours each week and are keen to use those 3 hours as efficiently has possible. The library is full of medical and nursing journals, but how do you start?

One suggestion is that you start by gathering a list of frequently asked questions ( FAQs ); that is, those questions you often ask yourself during your clinical work, and those often asked by your colleagues. For example:

Is it safe for patients with diabetes to inject insulin directly through their clothing without skin cleansing?

Is it useful to give dietary supplements to critically ill patients on your ward?

Should you be educating and counselling patients who have had a myocardial infarction, while they are still in hospital?

If you apply what you have learned about asking answerable questions to the first question in your list, it becomes 2 :

Is it effective and safe for patients with diabetes to inject insulin through clothing compared with the standard technique of skin cleansing and injection?

The most important lesson to learn about filtering your reading is to read only studies or reviews that have used an appropriate design to answer your particular question. The question about insulin injection is a question of whether a particular treatment (ie, injection of insulin through clothing) is effective and whether it is safe. In an earlier EBN notebook, we learned that randomised controlled trials (RCTs) are the strongest research design for answering this type of question. Systematic reviews of RCTs are better still as they summarise all the RCTs done on a particular topic. 5 Searching Medline using PubMed on the Internet (a free service that can be found at http://www.ncbi.nlm.nih.gov/PubMed/ ) with the terms insulin AND inject* AND cloth* AND clinical trial identifies 2 papers, one of which is a report of a study that appears to directly address our question.

The next step is to look at the study or review and decide whether it is valid and clinically applicable. Some of our medical colleagues have developed an excellent series of Users' Guides to the Medical Literature , and we intend to use these guides as a basis for this series. 9 As you might expect, separate guides exist for different types of clinical questions, as each is best answered using a specific study design. Regardless of the type of study, the clinician should always ask whether the results of the study are valid—that is, is the way the study was done likely to give a true result? The criteria to look for under this broad heading of validity vary, depending on whether the question is about treatment, prognosis, harm, or about understanding complex phenomena, such as feelings or perceptions. The validity checks can be applied quickly, and with a little practice, you will be able to decide efficiently whether to read a paper at all (on the principle that if the methods are not valid, there is no point in reading the paper). For example, the filtering question for a clinical question about whether a treatment works or not is was the assignment of patients to treatments randomised? If a study fails the basic filtering question, you will need to consider carefully whether or not to read it as it is not likely to direct your practice safely.

This approach to filtering your reading helps to keep the amount you do have to read to a manageable amount. If a study passes the validity filtering question and warrants a more detailed review, then there are further questions to help you determine the study validity with greater confidence, and others to help you tease out what the results of the study really mean, and whether they apply to your patients.

Returning to your question of injecting insulin through clothing, a search of Medline on PubMed would have identified a paper by Fleming and colleagues, which compared insulin injection through clothing with conventional techniques. 10 Better still, a search through back copies of Evidence-Based Nursing would have identified that the Fleming study had been summarised in a structured abstract, accompanied by a commentary that addressed the question of clinical applicability. The answer seems to be that injecting insulin through clothing appears to be as safe as conventional techniques and more convenient. 11

To make the most efficient use of the limited time available to keep abreast of clinical evidence, we should filter our reading so as to read only studies or reviews that are likely to provide valid results to our focused clinical questions. We should always look for high quality systematic reviews on a topic for which the author has already identified, appraised, and summarised the relevant studies. Other sources of pre-appraised research, such as the evidence-based journals and Clinical Evidence, can also save us work. Where pre-appraised research is not available or up to date, simple critical appraisal questions can help us to rapidly filter the useful studies from those that contain useless or even harmful information, and help us make decisions about clinical applicability. The figure ⇓ summarises this approach to reading. Critical appraisal checklists for use in appraising different study designs will form the basis of future users' guides.

Practitioners will find this an invaluable companion for navigating through evidence to identify quality literature applicable to health and social care practice.' 

'Students often struggle with writing an effective literature review and this invaluable guide will help to allay their concerns. Key terms are clearly explained, and the inclusion of learning outcomes is a helpful feature for students and lecturers alike.  The examples are also very helpful, particularly for less confident students.  This is an accessible yet authoritative guide which I can thoroughly recommend.' 

'A must have - this book provides useful information and guidance to students and professionals alike. It guides the reader through various research methods in a theoretical and pragmatic manner.' 

' It's a very readable, concise, and accessible introduction to undertaking a literature review in the field of healthcare. The book’s layout has a logical format which really helped me to think methodically about my research question. An excellent reference for undergraduates who are about to undertake their first literature review.' 

'This book is an essential resource for students. Clearly written and excellently structured, with helpful study tools throughout, it takes the reader step by step through the literature review process in an easy, informative and accessible manner. This text gives students the skills they need to successfully complete their own review.' 

'The updating of the chapters will be exceptionally helpful given the rapid changes in online availability of resources and open-access literature.'  

Excellent resource. Useful for any stage of studying

Excellent text for masters and doctoral level students

An excellent primer to help the level 7 students write their systemised review for the assignment.

This book provides a comprehensive overview of the practical process of literature review in healthcare. It contains all details required to conduct a review by students.

This is an excellent clear and concise book on undertaking literature reviews being particularly good at demystifying jargon. It is timely given the move to student dissertations being primarily literature reviews in the current Covid pandemic. However nearly all the examples are drawn from nursing and health making the text less useful for social care and social work. A little disappointing given the title. SW students are likely to gravitate to texts where their subject is more prominent for a primary text.

Accessible, informative, step to step guide

This is a really helpful, accessible text for students and academic staff alike.

A really good addition to the repertoire of skills and techniques for understanding the essential process of literature reviewing.

What is a Literature Review?

A literature review is an essay that surveys, summarizes, links together, and assesses research in a given field. It surveys the literature by reviewing a large body of work on a subject; it summarizes by noting the main conclusions and findings of the research; it links together works in the literature by showing how the information fits into the overall academic discussion and how the information relates to one another; it assesses the literature by noting areas of weakness, expansion, and contention. This is the essentials of literature review construction by discussing the major sectional elements, their purpose, how they are constructed, and how they all fit together.

All literature reviews have major sections:

• Introduction: that indicates the general state of the literature on a given topic;
• Methodology: an overview of how, where, and what subject terms used to conducted your search so it may be reproducable
• Findings: a summary of the major findings in that field;
• Discussion: a general progression from wider studies to smaller, more specifically-focused studies;
• Conclusion: for each major section that again notes the overall state of the research, albeit with a focus on the major synthesized conclusions, problems in the research, and even possible avenues of further research.

In Literature Reviews, it is Not Appropriate to:

• State your own opinions on the subject (unless you have evidence to support such claims).  
• State what you think nurses should do (unless you have evidence to support such claims).
• Provide long descriptive accounts of your subject with no reference to research studies.
• Provide numerous definitions, signs/symptoms, treatment and complications of a particular illness without focusing on research studies to provide evidence and the primary purpose of the literature review.
• Discuss research studies in isolation from each other.

Remember, a literature review is not a book report. A literature review is focus, succinct, organized, and is free of personal beliefs or unsubstantiated tidbits.

The authors were thorough and very organized in stepping readers through the process of conducting and writing a literature review. Each area is appropriately indexed and examples are provided in a variety of ways. The synthesis section is especially useful as students often do not understand what this means. Perhaps some content on plagiarism would benefit this section as well. The flow of the material easily guides users logically through each topic.

Content Accuracy rating: 5

The content is accurate and unbiased. The content is presented in an easy to understand way with videos, and examples.

Relevance/Longevity rating: 5

The relevance of the content is classic and the text should be pertinent for many years. The links included in the text are very useful and should be easy for authors to check periodically. Using a digital media is more relevant to today's students than print textbooks. Each section addresses a reasonable chunk of information.

Clarity rating: 5

The book is user friendly, written in an easy to understand manner, and graphics or links add to the understanding of the content. Definitions are clearly written. Such as clarifying the types of literature reviews will be useful for students. Providing a test yourself section at the end of sections allows the reader to check if any content was confusing or not clear.

Consistency rating: 5

The text is consistently laid out in a logical manner which helps to unpack content which may be new or unfamiliar to the reader/student.

Modularity rating: 5

The amount of content allocated to each chapter is appropriate and will be easy to assign readings. The chapter headings are clear and the embedded videos, charts and test questions enlighten each subunit. The hyperlinking in the table of contents helps to navigate the chapters well.

Organization/Structure/Flow rating: 5

The organization of the content is logical and easy to understand the process of completing a literature review. The book is laid out much like a road map where students can see the big picture as well as the supporting parts to the process. The references by chapter are very useful.

Interface rating: 5

The graphics were clear, and the non-serif font aids in eye fatigue. One recommendation is to lower the brightness of the bold blue text in the table of contents to reduce eye fatigue. There was no problem to play the videos and the audio was clear. All links worked well.

Grammatical Errors rating: 5

There were no grammatical errors. There were a few typos such as 1.3.1.8 needs a space between "A specific", 2.3 in the phrase "Articles by the type of periodical in which an article it is published" perhaps remove the word "it", in the table on page 41. under Nursing , the word clinical is spelled "Cclinical", remove the capital C.

Cultural Relevance rating: 5

No evidence of cultural bias or insensitivity.

I am very excited to use this textbook in my doctoral level occupational therapy class. The inclusion of concise explanations of PICO and SPICE will be very useful. This will be a wonderful resource for graduate students and being mindful of costs for textbooks is compassionate.

Each chapter presented a different aspect of doing a literature review. This was organized and orderly. The index/table of contents was very detailed which allowed the reader to easily use this book as a reference while conducting a literature review.

The content appeared to be entirely accurate. It did a good job of combining information for both education and nursing students. The authors addressed pertinent points of research study development as well as the specific methodology of approaching a research-focused literature review.

The text was up-to-date in methodology, which should not change frequently. The many links to websites were very helpful and yet were basic enough that they should be relevant for years. If they do need updating, the are clearly presented and should be easily updated. The breakdown to very small "chunks" of information per section will help in easily updating specific parts of information.

The book presented a rather complex topic in an extremely straight-forward, easy to read, clear manner. Each small "chunk" of information was identified per section numbering which correlated with movement through the content. The writing was professional and yet not overwhelmed with discipline-specific terminology. Where potentially new terminology was presented, it was immediately followed with definitions and examples.

The book was well-organized and moved along the structure set out early in the book. Content was gradually unfolded, as divided per chapter. There was a bit of repetition (probably about three examples) where the authors attempted to tie information together. Although this stood out to a reader, it seemed more useful in organizing than detrimental in repetition.

The book was subdivided into chapters and then into many small modules of discrete information. It could easily be assigned in part. It could also readily be used as a reference for students to go back and easily find processes or pieces of information they might need later.

I found the continual clear and succinct organization of information to be a defining highlight of this book. When presenting early steps of the research process and then linking these steps with how to conduct a literature review and subsequenty organize and write a literature review, this book is presenting numerous procews steps that must work in tandem. This book did that in a clear and easily readable fashion.

The one feature that did distract me was within the bullet points of 1.3.1. "Types of Reviews". There was a mix of complete and incomplete sentences that worked to convey information succinctly, but distracted me as a reader.

Grammatical Errors rating: 4

I did find several spelling and grammaticl errors (1.3.1.8, , 1.3.1.9, 2.1.1, 2.3, 2.3.1.1, , 2.3.1.4, 2.3 Table A., p. 41, p. 53, p. 54). Although small errors (a few letters or spacing) they should be corrected.

I did not find any mistakes in cultural appropriateness The content did repeatedly talk about bias reduction in the process of writing a literature review

I thought this book was very well-written and contained great information for my students. The links provided were very appropriate and helpful. The Table "Guide to searching for literature at various stages of the scholarly communication process” was particularly helpful. I will immediately begin using portions of the content in this book to support my research class. Additionally, I will recommend the entire book as a reference for the dedicated student (or one intending to go forward to a doctoral level of education in nursing). Thank you for collating all this information and helpful links into one clear, easily readable and understandable document.

This book addresses the basic steps in the process of writing a literature review research. Chapter 2 (What is a Literature Review?) needs to be retitled. I think Chapter 1 (Introduction) clearly defines and characterizes literature review as a research category. Chapter 2 focuses more on the creation of information, information cycle, and selecting appropriate sources. Chapter 7 (Synthesizing Sources) and Chapter 8 (Writing the Lit Review) can still be improved to incorporate specific strategies in synthesizing research literature and examples of writing styles through analysis of a variety of published examples. Writing a synthesis is a challenging skill for most novice researchers.

Information shared is accurate. I did not notice any content error.

Relevance/Longevity rating: 4

Main content is up-to-date. A few citations maybe dated but they are necessary in illustrating different examples of literature reviews. It will be easy to include additional relevant examples of research work that are published recently.

I like how this text is written. Tone is reader friendly and narrative is accessible to novice researchers.

Clearly consistent throughout the chapters.

Clear and purposeful "chunking" of information per chapter.

Readers can easily follow the organization of topics and content.

No obvious interface issues. Appropriate use of multimedia tools.

No grammatical errors.

Text is culturally sensitive. Additional readings, references, or examples can easily be added to incorporate research conducted by diverse authors or literature reviews which focus on diversity and inclusion issues in education and nursing.

This is a good introductory literature review text even for undergraduate education students. Clear discussion of the nature of the research and the writing process. The use of videos and images is helpful in providing multimodal approach in explaining topics or processes. Writing style and tone make the text accessible to novice researchers.

Two missing topics were inter-library loan and how to avoid plagiarism in writing up the literature review. This second is such an important topic that it deserves its own chapter.

It is accurate. I found no inaccuracies.

This book is very relevant. Every advanced undergraduate or graduate students requires such a book

I found the book clear. The videos interspersed within the book added much to the clarity. There are lots of good diagrams that add to the clarity. They are not all original but their sources are all cited. The section on boolean searches, usage of asterisks and quotes in searches is very helpful and appropriate although often left out of discussion of searches.

The book is consistent in terminology and framework.

The chapters were cohesive.

Organization/Structure/Flow rating: 4

I like the links to within the text to the references and other matter. What is needed are back links to the text from the references. I also would have liked links from the exercises to the answers of the exercises.

See navigation links mentioned above. The grey literature link is broken.

I saw no grammatical problems. There are many bulleted lists rather than text which is appropriate to this topic.

There could be more attention to cultural context in the frequent examples.

I wondered why nursing and education were combined. They are similar in nature but not identical. separation them out into two books might be appropriate.

Overall, this book provides a very comprehensive and thorough roadmap for creating a literature review. The videos assist the reader in crystallizing the information presented in the text. There is an effective index and glossary that provide helpful navigation to the reader.

The content is detailed, clearly explained, error-free, and unbiased. My students would greatly benefit from the lucid information presented in this text to guide them with developing a literature review. I would be eager to adopt this book for my students.

The content is timely and will not be quickly out-of-date. The quiz questions at the end of each chapter are relevant and will aid students with the consolidation of the material. The online format allows for updating, and the version history at the end of the text clearly indicated that the book was updated recently.

The text is clear and not ridden with any excess jargon /technical terminology. Pictures, graphics, and videos further elucidate the text. There are helpful questions that stimulate thought and lists that help to organize information.

The internal consistency in the text is excellent. However, Chapter 1.1 and Chapter 2 have the same title and it would benefit the reader to have different titles that would highlight the differences between these two sections. Chapter 1.1 is an overview and Chapter 2 dives into more depth.

The text is efficiently divided into smaller reading sections that are demarcated by numbers. The subsections in each chapter can be assigned at different points in the course. The text is organized logically and systematically that assists the reader with comprehension and provides a roadmap for creating an effective literature review.

The entire text is presented coherently and concisely. The organization of the text takes the reader through the process of creating an effective literature review. It can be used by multiple health professions, although the length of the text is relatively short it includes a considerable depth of the material. Other disciplines that would benefit from using this test in their courses may include occupational therapy, physical therapy, and speech and language pathology students.

The interface of the text is simple and easy to follow. The cover of the text would benefit from photos, color, and graphic design to appeal to the modern digital reader.

No grammatical or spelling errors are noted.

No cultural biases existed in the text in any way. There are no individuals highlighted in the book, and due to the technical nature of the subject matter, the text is inclusive to a variety of races, ethnicities, and backgrounds. No offensive statements are included in this book.

The authors should consider including other health professionals in the title and provide examples that can relate to other health professionals throughout the text. Other health professionals that can benefit from reading this text include occupational therapy, physical therapy, and speech and language pathology students. Literature reviews are relevant for many health professionals in their master's and doctorate programs and the text could serve a wider audience.

I really liked the way the textbook is structured. The author is concise which makes the textbook easy to read.

I found no inconsistencies in terminology or other aspects related to the content.

I will adopt this text for a research course I use and will likely assign only specific chapters. I plan to recommend the textbook to another faculty who teaches a comprehensive research course with the idea of assigning only specific sections to read..

The textbook begins with an introduction to the subject matter. Subsequent chapters develop specific aspects related to lit reviews. The textbook provides a nice "how to" for each element of a lit review. Chapters are also organized in a smooth, easy to follow format.

I only looked at the digital pdf and print pdf versions. The print pdf indicates that there are videos to watch, but of course since it is a print pdf, there is no linkage. I think this would be obvious to a savvy reader - that a print pdf will be limited in what the reader can access.

I found no grammatical errors in my quick read.

I found no evidence of cultural bias or insensitivity.

This is the first open textbook that I have encountered. I was expecting it to be flat and boring! However, it was neither of those. There were color diagrams, color photos, and even videos embedded in the textbook.

I have adopted this book for the Research Lit Review course that I am teaching soon. I am impressed!

This book helps students in education and nursing complete a literature review, which may be the first time these students are tackling such a task. The chapters break down the process into defining the special genre of a literature review; providing tips to get started; suggesting where students can find literature to review; explaining how to evaluate sources; detailing the process of documenting sources; giving advice for synthesizing sources; and finally, putting all of these pieces together into a final literature review. Most significantly, the text provides specific examples of ideas presented in the context of both nursing and education, which makes the content directly relatable to the student's course of study. The conclusion recaps the main points of each chapter in bullet form. The text is lacking both an index and a glossary, which would be additions that could strengthen the text.

Content Accuracy rating: 4

The text explains 11 different types of literature reviews that students may encounter or be asked to create. Also, the text is framed to work with multiple methodologies; for example, steps for writing a research question or a hypothesis to frame the literature review are provided. One inconsistency I noted was in diagram 6.2: the APA citation is incorrectly capitalized for the journal title (which should use sentence, not title, capitalization).

The text also includes external links to sources, such as a videos, which provide students with multiple modalities in which to digest the information. An example of a literature review for both education and nursing is provided at the end of the book; instead of embedding these in the text, the hyperlinks refer the reader to the external site. This will be easy to change to a new example in the future, but checks will need to be done to ensure that all such external sources remain actively accessible.

Each chapter opens with learning objectives to help frame the content with which the reader is about to engage. Throughout the text, the language is approachable and reader-friendly. For example, when the text explains more factual components (i.e., what makes a literature review or what the basics of an effective literature review include), this information is presented in bullet points with hyperlinks to the original sources.

Each chapter follows a similar construction, which makes it accessible to the reader. For example, chapters end with a "Practice" and "Check Yourself" section to apply new learning and self-check responses (an answer key is provided in an appendix). Examples in these exercises are either related to nursing or education, continuing with the stated theme of the text.

When I used this text with my own students, I assigned chapters in isolation, since they had already taken a research methods course and were applying that knowledge to create a research proposal in a specific area of study in my course.

The book is organized in such a way that logically walks the reader through the literature review writing process. Clear headings (which are hyperlinked in the table of contents) also allow the reader to jump to specific parts with which they need additional support.

The interface of this document offered a lot of flexibility. Options allowed users to access the text online, or as a download in multiple file types (EPUB, Digital PDF, MOBI, XHTML, Pressbooks XML, Wordpress XML, and Open Document). These formats provide the reader with an opportunity to pick the interface that works best for them.

I did not see any grammatical errors in the text.

Cultural Relevance rating: 4

No culturally insensitive/offensive content was noted. A variety of examples of research topics were included from both nursing and education. Of the images/video thumbnails embedded in the text that involved people, all depicted White people except for 2 images; therefore, more intentional selection of culturally diverse visuals would be helpful in future versions of this text.

I feel this text was helpful to my students as they wrote their own literature reviews. The only weakness in their papers that I noted was their organization of their literature review based on themes/topic, which was addressed in Chapters 7- 8. I now know to focus more on this part of literature review writing with future students. This text is approachable and field-specific, and I will be using it again!

The text is overall comprehensive, yet it breaks the information up into manageable parts. See the table of contents for an overview of the topics. The text is very quantitative driven in that the focus is on reviewing quantitative studies. The book included information about PICO statements, but did not include PICO(T) or the time variable, which is not always used in every case. Population was included in the PICO explanation, but a bit more information on the population or aggregate narrowing could improve the PICO section. These items do not hinder use of the book, but these items would need further inclusion by the faculty member using the text as specific to the discipline.

The content in the book is very accurate.

The content in the book is current and should not be obsolete within a short period of time. Any updates would be easy to add.

The text is clear and easy to understand.

The internal organization and terminology of the book is consistent and logical

The text is set up in small reading sessions. The videos and learning activities are well done and break up some of the content, so there is a variety of presentation. The tutorials, figures, practice and self-test areas are also fantastic in that they are quality and sprinkled throughout the text.

The topics in the book are presented in clear and organized fashion. I particularly like the upbeat and personal writing tone of the book. This tone makes it seem like the authors are speaking to me.

The text is free of any significant interface issues. The book is available in many formats. I used the book online and I did have one navigational problem and that is when clicking on a video, it does not open in a new tab and so the book is lost and have to start over going in the start to the book. One easy solution to this is to right click your mouse and then select open in new tab to watch videos. That way, your place in the book is not lost.

No grammar problems present.

The book is not culturally insensitive or offensive in any way.

Overall, this is a well written textbook and I recommend it!

From the Introduction to the Conclusion, the text covers the step-by-step process of conducting a literature review. The text includes topics such as, “Where to find the Literature” and “Synthesizing Sources” that will be useful to graduate nursing students.

The content in the text, including texts, links, and diagrams, is accurate and unbiased. Again, it will aid the graduate nursing student in the long process of conducting a literature review.

The text is current and this type of material does not become dated quickly. The authors did use internet links in the text which will need to be monitored periodically to ensure they are still available. Updates to the text will be relatively easy and straightforward. If media styles change, there may be some challenges to updating.

The text is clear and easy to read. Technical terminology is defined and/or explained.

The text is internally consistent.

The text is organized in sections which facilitates assigning readings based on the subject matter for the class time. It would be pretty easy to divide up this text into easily readable units based on headings and subheadings.

This text is structured well. The topics flow in an organized manner and really help the student see the process of a literature review. The authors discuss the both theory and purpose of the review and the day-to-day logistics of actually performing the review. The day-today organization is not always included in other texts.

The interface is well-done with no distractions.

There was no indication of cultural bias.

I think this text is appropriate for graduate nursing students. Some students struggle with the difference between writing about a topic (generally undergraduate writing) and synthesizing literature on a given topic (generally graduate writing). Chapters seven and eight focus on preparing the graduate student to make the jump to graduate-level writing and should really benefit new graduate students.

This book is fairly comprehensive and offers step-by-step instructions for conceptualizing/researching a literature review. The Table of Contents is well-organized to reflect the book's progression, from establishing the basics of why to write a literature review and the various types of literature reviews, to getting started with formulating a research idea/question, finding and evaluating sources, synthesizing sources, and guidelines on writing the literature review, itself. I found this text to be a straightforward guide for my graduate students in education, and while I worried at first that the merging of education and nursing topics would prove distracting to my education students, I don't believe this was the case.

One thing that was not comprehensive in this book was discussion of qualitative research and methodologies as a valid means of conceptualizing research aims. I hoped for a more balanced discussion between methodological branches as it applied to literature reviews; this book overly favored quantitative methodologies and studies in terms of its direction to readers about how to conceptualize/choose a topic and design a research question in relation to it. Variables that cannot be measured are not inherently un-researchable, which is the conclusion put forth in this textbook. This might serve nursing students better than education students in terms of their discipline's requirements, but it still represents an element that could be improved.

Finally, while the background on what a literature review is, how to conceptualize research, and how to search for and synthesize research was all valuable, the chapter on actually writing the literature review was a bit thin, simply offering tips for introduction, body, and conclusion and some questions for self-evaluation. Some of the most difficult work for students writing a literature review is achieving proper focus, organization, hierarchy of themes, balance in treatment of related topics, etc. None of these issues were discussed in the chapter pertaining to the writing of a literature review.

I did not have any concerns about the book's accuracy. Content was accurate, albeit biased to quantitative and positivist views of research. I would have liked to see it include additional prompts to support students in conceptualizing and valuing qualitative research; this is an area where I had to supplement course readings with additional texts.

The only significant error I could discern in the text was a lack of an Answer Key corresponding to the questions posed at the end of each chapter.

Content is up-to-date and seems like it will hold meaning well over the next few years. The only things I anticipate might go out-of-date is technological information on things like citation managers, search guidelines, and database information. This is easily updatable with future versions of the text. In my view, ERIC is not the best database for educational research and I have confirmed this with educational librarians who support my students, yet it is the only one identified in this text as the best subject-specific source of educational research; this could be revised for additional relevance.

I noticed no issues with the book's clarity. The authors write in a clear and straightforward style, making the text easy to read. Overall, they did well writing for students across two disciplines by avoiding nursing or education-specific terms that would have been problematic to readers in the other discipline.

The book is internally consistent and did not have issues with terminology or framework.

No issues with the book's modularity. Chapter headings and sub-headings were appropriately paced and spaced. I assigned this textbook to my graduate students as a whole text that I wanted them to read at the beginning of a course, but it has been easy to refer them back to particular topics as the course has continued.

In future iterations of the book, I suggest hyperlinking the Answer Key to the exercises at the end of each chapter and/or listing the Answer Key in the Table of Contents for easy referral.

I found the book's organization to be straightforward and sensible. The Table of Contents offers a helpful snapshot of the scope of the book and the authors write in a direct and clear style, which contributes to an appropriate flow for the text.

I did not note any navigation problems with any links. All charts/images loaded well in my iBook app. The authors did a nice job of pulling relevant content and links in to support their ideas; it provided an easy way to seek more information if I wanted it, without feeling like the text was loaded down with unnecessary information.

I only found a few small typos in the text, with no grammar issues. The book is obviously written by two very detail-oriented librarians. I appreciated the clarity of the text and lack of errors.

The text was not culturally insensitive; a variety of topics across nursing and education were discussed as examples, which yielded a fairly balanced text regarding cultural considerations.

I believe the book gives a comprehensive overview on how to complete a literature view at the graduate level. It begins with an overview of the purpose of a literature review and moves through the steps to completing the review process.

I believe the book was accurate and unbiased. It was easy to read but comprehensive.

Content within the text is relevant and supports the literature view process. It did discuss the various databases for searches which may need updating to include new sites, search engines but otherwise relevant and useful information.

The text is easy to read, provides appropriate examples, includes a section on putting the process into practice as well as a "test yourself" section to ensure the content is understood.

The text is consistent throughout in regards to terminology, framework, and set up.

The text is easy to read and content is leveled for the reader but not over simplified. Content is chunked into sections making it easy for the reader to digest the content. The chapters are well laid out and flow from chapter to chapter. Each chapter contains learning objectives, content sections, practice section, and test yourself section. Well organized and great visuals.

Topics are presented in a logical, clear fashion that flow from chapter to chapter and build as the reader moves through the process.

The text is free of interface issues. I could not get the videos to play but other visuals were appropriate and useful to support content.

The text contains no grammatical errors.

The text is not culturally offensive. There was no evidence of bias or cultural insensitivity.

I think this would be a great resource for graduate student learning to navigate the literature review process. It is easy to read, straightforward, and guides the individual through the process from start to finish. I will recommend this text to my graduate students in evidence-based practice and research courses as a recommended reference.

Nursing Literature Reviews

What is a Literature (Lit) Review? 

A Literature Review is Not: 

• a quick summary of sources
• a grouping of broad, unrelated sources
• a compilation of everything that has ever been written on a topic
• a literature criticism or book review

So, what is it then?

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

Creating a Literature Review using the Matrix Method: 

A matrix review allows you to quickly compare and contrast articles in an easy to read format. It can help you to easily spot differences and similarities between journal articles and your nursing research topic. Review matrices are especially helpful for health sciences literature reviews that cover the scope of research over a given amount of time. 

Most literature reviews are set up in this format: 

Chart adapted from the book below: 

• Check out the e-book above for more help in creating a literature review matrix. 

Steps for Conducting a Literature Review

1. Choose Your Topic

• Review your PICO question and think about your central research question. To review the PICO process, please see Kerry Sewell's LibGuide on this subject. 

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? (Dr. Larson usually prefers articles no older than 5 years)

3. Select the databases you want to use to conduct your searches (See the Databases Tab Above!)

4. Conduct your searches and find the literature. (Keep track of your searches)

• Review the abstracts and conclusions carefully. This will help you decide which articles actually fit the criteria you are looking for. 
• Write down the keywords you used and where you found them. 
• Use RefWorks to keep track of your citations. (Email me  - [email protected] -  if you need help!) 

5. Review the Literature (This will probably be the most time consuming part)

• What was the research question of the study you are reviewing?  What were the authors trying to discover? 
• Was the research funded by a company or source that could influence the findings? (Such as Colgate® sponsoring a toothpaste study?)
• What were the research methodologies? Analyze the paper's literature review, the samples and variables used, the results and conclusions. Does the research seem to be complete? Could it have been conducted more soundly? What questions does it raise? 
• If there are conflicting studies, why do you think that is? 
• How are the authors of the paper viewed in the field? Has this study been cited by other publications? 

Literature Review Examples

Remember, a lit review provides an intelligent overview of the topic. There may or may not be a method for how studies are collected or interpreted. Lit reviews aren't always labeled specifically as "literature reviews," they may often be embedded with other sections such as an introduction or background.

So you have been asked to complete a literature review, but what is a literature review?

A literature review is a piece of research which aims to address a specific research question. It is a comprehensive summary and analysis of existing literature. The literature itself should be the main topic of discussion in your review. You want the results and themes to speak for themselves to avoid any bias.

The first step is to decide on a topic. Here are some elements to consider when deciding upon a topic:

• Choose a topic which you are interested in, you will be looking at a lot of research surrounding that area so you want to ensure it is something that interests you. 
• Draw on your own experiences, think about your placement or your workplace.
• Think about why the topic is worth investigating.  

Once you have decided on a topic, it is a good practice to carry out an initial scoping search.

This requires you to do a quick search using  LibrarySearch  or  Google Scholar  to ensure that there is research on your topic. This is a preliminary step to your search to check what literature is available before deciding on your question. 

The research question framework elements can also be used as keywords.

• Think about who the population/ sample group. Are you looking for a particular age group, ethnicity, cultural background, gender, health issue etc.
• What is the intervention/issue you want to know more about? This could be a particular type of medication, education, therapeutic technique etc. 
• Do you have a particular context in mind? This could relate to a community setting, hospital, ward etc. 

It is important to remember that databases will only ever search for the exact term you put in, so don't panic if you are not getting the results you hoped for. Think about alternative words that could be used for each keyword to build upon your search. 

Build your search by thinking about about synonyms, specialist language, spellings, acronyms, abbreviations for each keyword that you have.

Inclusion & Exclusion Criteria

Your inclusion and exclusion criteria is also an important step in the literature review process. It allows you to be transparent in how you have  ended up with your final articles. 

Your inclusion/exclusion criteria is completely dependent on your chosen topic. Use your inclusion and exclusion criteria to select your articles, it is important not to cherry pick but to have a reason as to why you have selected that particular article. 

• Search Planning Template Use this template to plan your search strategy.

Once you have thought about your keywords and alternative keywords, it is time to think about how to combine them to form your search strategy. Boolean operators instruct the database how your terms should interact with one another. 

Boolean Operators

• OR can be used to combine your keywords and alternative terms. For example "Social Media OR Twitter". When using OR we are informing the database to bring articles continuing either of those terms as they are both relevant so we don't mind which appears in our article. 
• AND can be used to combine two or more concepts. For example "Social Media AND Anxiety". When using AND we are informing the database that we need both of the terms in our article in order for it to be relevant.
• Truncation can be used when there are multiple possible word endings. For example Nurs* will find Nurse, Nurses and Nursing. 
• Double quotation marks can be used to allow for phrase searching. This means that if you have two or more words that belong together as a phrase the database will search for that exact phrase rather than words separately.  For example "Social Media"

Don't forget the more ORs you use the broader your search becomes, the more ANDs you use the narrower your search becomes. 

One of the databases you will be using is EBSCOHost Research Databases. This is a platform which searches through multiple databases so allows for a comprehensive search. The short video below covers how to access and use EBSCO. 

A reference management software will save you a lot of time especially when you are looking at lots of different articles. 

We provide support for EndNote and Mendeley. The video below covers how to install and use Mendeley. 

Consider using a research question framework. A framework will ensure that your question is specific and answerable.

There are different frameworks available depending on what type of research you are interested in.

Population - Who is the question focussed on? This could relate to staff, patients, an age group, an ethnicity etc.

Intervention - What is the question focussed on? This could be a certain type of medication, therapeutic technique etc. 

Comparison/Context - This may be with our without the intervention or it may be concerned with the context for example where is the setting of your question? The hospital, ward, community etc?

Outcome - What do you hope to accomplish or improve etc.

Sample - as this is qualitative research sample is preferred over patient so that it is not generalised. 

Phenomenon of Interest - reasons for behaviour, attitudes, beliefs and decisions.

Design - the form of research used. 

Evaluation - the outcomes.

Research type -qualitative, quantitative or mixed methods.  

All frameworks help you to be specific, but don't worry if your question doesn't fit exactly into a framework. 

There are many critical appraisal tools or books you can use to assess the credibility of a research paper but these are a few we would recommend in the library. Your tutor may be able to advise you of others or some that are more suitable for your topic.

Critical Appraisal Skills Programme (CASP)

CASP is a well-known critical appraisal website that has checklists for a wide variety of study types. You will see it frequently used by practitioners.

What is a Literature Review?

The Scholarly Conversation

A literature review provides an overview of previous research on a topic  that critically evaluates, classifies, and compares what has already been published on a particular topic. It allows the author to synthesize and place into context the research and scholarly literature relevant to the topic. It helps  map the different approaches to a given question and reveals  patterns.  It  forms the foundation for the author’s subsequent research and justifies the significance of the new investigation.

A literature review can be a short introductory section of a research article or a report or policy paper that focuses on recent research. Or, in the case of dissertations, theses, and review articles, it can be an extensive review of all relevant research.

• The  format  is usually a bibliographic essay; sources are briefly cited within the body of the essay, with full bibliographic citations at the end.
• The  introduction  should define the topic and set the context for the literature review. It will include the author's perspective or point of view on the topic, how they have defined the scope of the topic (including what's not included), and how the review will be organized. It can point out overall trends, conflicts in methodology or conclusions, and gaps in the research.
• In the  body of the review , the author should organize the research into major topics and subtopics. These groupings may be by subject, (e.g., globalization of clothing manufacturing), type of research (e.g., case studies), methodology (e.g., qualitative), genre, chronology, or other common characteristics. Within these groups, the author can then discuss the merits of each article and analyze and compare the importance of each article to similar ones.
• The  conclusion  will summarize the main findings, make clear how this review of the literature supports (or not) the research to follow, and may point the direction for further research.
• The  list of references  will include full citations for all of the items mentioned in the literature review.

Systematic Literature Reviews: Steps & Resources

These steps for conducting a systematic literature review are listed below . 

Also see subpages for more information about:

• The different types of literature reviews, including systematic reviews and other evidence synthesis methods
• Tools & Tutorials

Literature Review & Systematic Review Steps

• Develop a Focused Question
• Scope the Literature  (Initial Search)
• Refine & Expand the Search
• Limit the Results
• Download Citations
• Abstract & Analyze
• Create Flow Diagram
• Synthesize & Report Results

1. Develop a Focused   Question 

Consider the PICO Format: Population/Problem, Intervention, Comparison, Outcome

Focus on defining the Population or Problem and Intervention (don't narrow by Comparison or Outcome just yet!)

"What are the effects of the Pilates method for patients with low back pain?"

Tools & Additional Resources:

• PICO Question Help
• Stillwell, Susan B., DNP, RN, CNE; Fineout-Overholt, Ellen, PhD, RN, FNAP, FAAN; Melnyk, Bernadette Mazurek, PhD, RN, CPNP/PMHNP, FNAP, FAAN; Williamson, Kathleen M., PhD, RN Evidence-Based Practice, Step by Step: Asking the Clinical Question, AJN The American Journal of Nursing : March 2010 - Volume 110 - Issue 3 - p 58-61 doi: 10.1097/01.NAJ.0000368959.11129.79

2. Scope the Literature

A "scoping search" investigates the breadth and/or depth of the initial question or may identify a gap in the literature. 

Eligible studies may be located by searching in:

• Background sources (books, point-of-care tools)
• Article databases
• Trial registries
• Grey literature
• Cited references
• Reference lists

When searching, if possible, translate terms to controlled vocabulary of the database. Use text word searching when necessary.

Use Boolean operators to connect search terms:

• Combine separate concepts with AND  (resulting in a narrower search)
• Connecting synonyms with OR  (resulting in an expanded search)

Search:  pilates AND ("low back pain"  OR  backache )

Video Tutorials - Translating PICO Questions into Search Queries

• Translate Your PICO Into a Search in PubMed (YouTube, Carrie Price, 5:11) 
• Translate Your PICO Into a Search in CINAHL (YouTube, Carrie Price, 4:56)

3. Refine & Expand Your Search

Expand your search strategy with synonymous search terms harvested from:

• database thesauri
• reference lists
• relevant studies

Example: 

(pilates OR exercise movement techniques) AND ("low back pain" OR backache* OR sciatica OR lumbago OR spondylosis)

As you develop a final, reproducible strategy for each database, save your strategies in a:

• a personal database account (e.g., MyNCBI for PubMed)
• Log in with your NYU credentials
• Open and "Make a Copy" to create your own tracker for your literature search strategies

4. Limit Your Results

Use database filters to limit your results based on your defined inclusion/exclusion criteria.  In addition to relying on the databases' categorical filters, you may also need to manually screen results.  

• Limit to Article type, e.g.,:  "randomized controlled trial" OR multicenter study
• Limit by publication years, age groups, language, etc.

NOTE: Many databases allow you to filter to "Full Text Only".  This filter is  not recommended . It excludes articles if their full text is not available in that particular database (CINAHL, PubMed, etc), but if the article is relevant, it is important that you are able to read its title and abstract, regardless of 'full text' status. The full text is likely to be accessible through another source (a different database, or Interlibrary Loan).  

• Filters in PubMed
• CINAHL Advanced Searching Tutorial

5. Download Citations

Selected citations and/or entire sets of search results can be downloaded from the database into a citation management tool. If you are conducting a systematic review that will require reporting according to PRISMA standards, a citation manager can help you keep track of the number of articles that came from each database, as well as the number of duplicate records.

In Zotero, you can create a Collection for the combined results set, and sub-collections for the results from each database you search.  You can then use Zotero's 'Duplicate Items" function to find and merge duplicate records.

• Citation Managers - General Guide

6. Abstract and Analyze

• Migrate citations to data collection/extraction tool
• Screen Title/Abstracts for inclusion/exclusion
• Screen and appraise full text for relevance, methods, 
• Resolve disagreements by consensus

Covidence is a web-based tool that enables you to work with a team to screen titles/abstracts and full text for inclusion in your review, as well as extract data from the included studies.

• Covidence Support
• Critical Appraisal Tools
• Data Extraction Tools

7. Create Flow Diagram

The PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) flow diagram is a visual representation of the flow of records through different phases of a systematic review.  It depicts the number of records identified, included and excluded.  It is best used in conjunction with the PRISMA checklist .

Example from: Stotz, S. A., McNealy, K., Begay, R. L., DeSanto, K., Manson, S. M., & Moore, K. R. (2021). Multi-level diabetes prevention and treatment interventions for Native people in the USA and Canada: A scoping review. Current Diabetes Reports, 2 (11), 46. https://doi.org/10.1007/s11892-021-01414-3

• PRISMA Flow Diagram Generator (ShinyApp.io, Haddaway et al. )
• PRISMA Diagram Templates  (Word and PDF)
• Make a copy of the file to fill out the template
• Image can be downloaded as PDF, PNG, JPG, or SVG
• Covidence generates a PRISMA diagram that is automatically updated as records move through the review phases

8. Synthesize & Report Results

There are a number of reporting guideline available to guide the synthesis and reporting of results in systematic literature reviews.

It is common to organize findings in a matrix, also known as a Table of Evidence (ToE).

• Reporting Guidelines for Systematic Reviews
• Download a sample template of a health sciences review matrix  (GoogleSheets)
