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
• Strategies for organizing the information for your review
• Literature reviews sections
• In-depth resources to assist in writing a literature review
• Templates to start your review
• Literature review examples

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

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 ?

Praise for the previous edition:

'This book is an excellent resource for practitioners wishing to develop their knowledge and understanding of reviewing literature and the processes involved. It uses uncomplicated language to signpost the reader effortlessly through key aspects of research processes. 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.

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

Web Resources

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.

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.

How to undertake a literature search

Introduction.

Undertaking a literature search can be a daunting prospect. By breaking the exercise down into smaller steps, you can make the process more manageable. The following ten steps will help you complete the task from identifying key concepts to choosing databases for your search and saving your results and search strategy. It discusses each of the steps in a little more detail with examples and suggestions of where to get help.

There are ten steps to undertaking a literature search which we'll take you through below:

🎬 - Indicates a video is available with more information.

Please click on the boxes below to get a bit more detail on each step.

First, write out your title and check that you understand all the terms. Look up the meaning of any you don’t understand. An online dictionary or medical encyclopaedia may help with this.

If your search is for a dissertation, you may need to choose your own research question. In this case, you will need to consider whether there is likely to be enough research on your topic. Alternatively, if your topic is too broad, you could be overwhelmed by the number of references.

One way of checking how much is written on your topic is to use Library Search. Most libraries offer a Library Search or discovery tool. It provides a quick search across all the library’s holdings. You can also limit your search by date or type of document. If you just need a few references to help you write an essay, Library Search may be helpful. It also gives quick access to full text items.

Next, you need to identify your key concepts. One way to do this is to look at your title and identify the most important words. Ignore words that tell you what to do with the information you find eg evaluate, assess, compare, as these are not generally used as search terms. In the example below, key concepts have been highlighted:

Evaluate the effectiveness of a mindfulness intervention on the health-related quality of life of rheumatoid arthritis patients

Another way to do this is to break down your title using the PEO framework:

P = Population    E = Exposure    O = Outcome 

This works well where there is no comparison between two types of treatment or intervention.

In our example:

P = rheumatoid arthritis patients

E = mindfulness

O =  health related quality of life

Other question formats are available such as PICO or SPIDER

Tip: Not all search topics will include every element of PICO – some include fewer items.

Once you have identified the key concepts, it’s important to think of any other terms or phrases that might have a very similar meaning. Including such synonyms will make your search as thorough as possible. For example, if your topic is looking for articles on Staff attitudes , you might also use the terms:

• Staff perceptions 
• Staff opinions
• Stereotyping
• Labelling 

If the database you are using has a list of subject heading s , this may help you to find the most appropriate term for your subject. Some databases provide definitions for terms used in the database and may suggest related terms.

A comprehensive search will usually include both subject headings from databases and terms that you have thought of yourself.

Tip: Often your search term will be a phrase instead of a single word. To carry out phrase searches, use double quotes, for example “problem drinking”.

Once you have chosen your search terms, you need to think about the best databases for your topic. The databases you choose will depend on the search question and the libraries you have access to.

Tip: It’s well worth taking a few minutes to get to know the databases available on the Library webpages and what they cover.

The next step is to combine your search terms in such a way that you only retrieve the more relevant references for your search question. In order to do this you need to build a search strategy . This involves using Boolean operators such as AND , OR and NOT .

AND narrows the results of the search by ensuring that all the search terms are present in the results. 

OR broadens the results of the search by ensuring that any of the search terms are present in the results.

NOT limits the results by rejecting a particular search term. Be careful with NOT because it will exclude any results containing that search term regardless of whether other parts of the article might have been of interest.

OR will broaden your number of results while AND will produce fewer results.

Try using this  Search-plan-worksheet   to break your topic down into concepts. These can then be linked together when you run the search. You can also add synonyms within each concept box. The yellow limits box is a prompt to think about any limits you want to apply when searching. This leads us to Step 6.

Tip: Most databases will allow you to use a truncation sign (*) or wildcard (?) to pick up various different endings to words or alternative spellings.

For example:  alcohol* would pick up alcohol, alcoholic, alcoholism, etc

Sm?th would find Smith and Smyth

The next step is to think about any other restrictions you want to make to your results.

Common limiters found on databases include:

• Peer reviewed articles
• Research articles
• Age group (adult, child, older person)
• Document type

Not all databases allow all of the limiters above.

When writing a dissertation, primary research articles are normally required. Where the database allows you, try limiting to research articles only.

Non-research materials can also be useful as an overview of your topic; for example a literature review can give an analysis of what has already been written on a topic.

The video below includes a demonstration of how limits can be applied using the CINAHL database as an example:

CINAHL - advanced

Once you have identified all your search terms and any limits you want to apply, you are ready to run your search on the databases you have chosen. 

Once you have some search results, you can look through them and start to select those that look relevant to your literature search. It is likely you will reject some because they are not quite what you wanted but there will be others that can be marked for further attention.

The title of an article on its own may not tell you very much; read the abstract quite carefully to see if the article is relevant or not.

Tip: You can show more details for each record by clicking on the article title. On some databases, there may be an abstract for the article which you can open. 

If you find you are either generating more results than you can possibly look at or too few results to write about, be prepared to adjust your search terms and the way they are combined.

If you get too many results you could try: •limiting to just the most recent material •adding another term or concept and linking it using “AND” •limiting to a particular country or geographical area such as UK

If you get too few results, you might try: •expanding your date range •removing any geographical limits you have applied  •removing the least important term or concept

Tip: Be prepared to try other databases and keep searching until you feel confident you have found enough relevant material.

Once you have selected some articles that look relevant for your piece of work, you will need to save them so that your hard work is not wasted.

At the same time, you will want to save your search strategy . This is a record of the terms you searched, how you combined them, any limits you applied and how many results you found.

You will also need to choose a way to save your results. One way is to email the results to yourself and this can be done from all the databases .

Another way is to export your results to reference management software such as Zotero, RefWorks, EndNote or Mendeley. This software allows you to collect, organise and cite research. It is suitable for managing references over a long period of time. 

The RCN Library and Archive Service provides help with using Zotero . 

Tip: Keep a record of all the databases you use as you carry out your search. It is also a good idea to note where you found any references you subsequently use for your dissertation.

The final step is to obtain the full text of the articles identified in your search which you believe may be useful for your assignment. If you are lucky, many of these will be available electronically and you may just be able to follow a link to the full text.

Alternatively you can copy and paste your article title into the Library search box  and if it is available as full text, a hyperlink will be shown which will link you to the document.

If you are studying elsewhere and have access to a university or hospital library, they may subscribe to different journals to the RCN Library so it is worth exploring what they can offer. If your library does not have either an electronic copy or a physical copy, you may need to request the article by interlibrary loan .

Tip: It is also worth using Google or other browsers to check for the article title you require. Sometimes the article has been made freely available on the internet by the authors.

Boolean operators – words (AND, OR and NOT) which can be used to combine search terms in order to widen or limit the search results.

Database – this is an online collection of citations to journal articles which have been indexed to make retrieval easier. Some databases which also provide full text access to the articles.

Limits – these are options within a database which allow search results to be broken down further. Common limits are year(s) of publication, document type and language. MEDLINE and CINAHL allow age limits too.

Search Strategy – the list of search terms and limits used to retrieve relevant articles from a database in order to answer a search question.

Subject headings – terms that have been assigned to describe a concept that may have many alternative keywords. All these alternative keywords or terms are brought together under the umbrella of this single term. Most health-related databases use subject headings.

Additional information

If after following these steps, you still can’t find what you are looking for, remember that there is always help available at your library. The RCN Library and Archives Service offers a range of help materials via our Literature searching and training pages . These include: • Databases guides in electronic and printed formats • Video tutorials on how to search the databases • 1-1 training sessions pre-bookable via the RCN website face to face or via zoom

Literature Review Example/Sample

Detailed Walkthrough + Free Literature Review Template

If you’re working on a dissertation or thesis and are looking for an example of a strong literature review chapter , you’ve come to the right place.

In this video, we walk you through an A-grade literature review from a dissertation that earned full distinction . We start off by discussing the five core sections of a literature review chapter by unpacking our free literature review template . This includes:

• The literature review opening/ introduction section
• The theoretical framework (or foundation of theory)
• The empirical research
• The research gap
• The closing section

We then progress to the sample literature review (from an A-grade Master’s-level dissertation) to show how these concepts are applied in the literature review chapter. You can access the free resources mentioned in this video below.

FAQ: Literature Review Example

Literature review example: frequently asked questions, is the sample literature review real.

Yes. The literature review example is an extract from a Master’s-level dissertation for an MBA program. It has not been edited in any way.

Can I replicate this literature review for my dissertation?

As we discuss in the video, every literature review will be slightly different, depending on the university’s unique requirements, as well as the nature of the research itself. Therefore, you’ll need to tailor your literature review to suit your specific context.

You can learn more about the basics of writing a literature review here .

Where can I find more examples of literature reviews?

The best place to find more examples of literature review chapters would be within dissertation/thesis databases. These databases include dissertations, theses and research projects that have successfully passed the assessment criteria for the respective university, meaning that you have at least some sort of quality assurance. 

The Open Access Thesis Database (OATD) is a good starting point.

Carrying out systematic literature reviews: an introduction

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

• How it works

Important Notes

As a student of medicine and nursing looking to get good grades, it is essential to develop new ideas and experiment with existing medicine and nursing theories – i.e., to add value and interest in the topic of your research.

The field of medicine and nursing is vast and interrelated to so many other academic disciplines like civil engineering ,  construction ,  law ,  healthcare , mental health , artificial intelligence , tourism , physiotherapy , sociology , management , marketing, cryptocurrencies and architecture . That is why it is imperative to create a project management dissertation topic that is articular, sound, and actually solves a practical problem that may be rampant in the field.

We can’t stress how important it is to develop a logical research topic; it is the basis of your entire research. There are several significant downfalls to getting your topic wrong; your supervisor may not be interested in working on it, the topic has no academic creditability, the research may not make logical sense, and there is a possibility that the study is not viable.

This impacts your time and efforts in  writing your dissertation  as you may end up in the cycle of rejection at the very initial stage of the dissertation. That is why we recommend reviewing existing research to develop a topic, taking advice from your supervisor, and even asking for help in this particular stage of your dissertation.

While developing a research topic, keeping our advice in mind will allow you to pick one of the best medicine and nursing dissertation topics that fulfil your requirement of writing a research paper and add to the body of knowledge.

Therefore, it is recommended that when finalizing your dissertation topic, you read recently published literature to identify gaps in the research that you may help fill.

Remember- dissertation topics need to be unique, solve an identified problem, be logical, and be practically implemented. Take a look at some of our sample medicine and nursing dissertation topics to get an idea for your own dissertation.
