How to Write a Nursing Literature Review: A Complete Student Guide

Writing a nursing literature review is an important academic skill for nursing students. Whether you are preparing a nursing assignment, research proposal, dissertation, thesis, or evidence-based practice project, a literature review helps you understand what researchers already know about a particular topic.

A nursing literature review is not simply a summary of research articles. A strong literature review identifies relevant evidence, compares different studies, evaluates their strengths and limitations, identifies patterns and gaps, and explains how the existing evidence relates to the research question.

For nursing students, learning how to write a literature review can also improve critical thinking, research skills, academic writing, and evidence-based decision-making.

This guide explains how to write a nursing literature review step by step, from selecting a topic and developing a research question to searching databases, evaluating sources, organising evidence, identifying research gaps, and writing the final review.

What Is a Nursing Literature Review?

A nursing literature review is a structured analysis of existing research and academic literature related to a nursing or healthcare topic.

It brings together information from relevant sources and examines what the available evidence shows.

A literature review may be used to:

• Understand an existing nursing problem

• Examine current evidence

• Identify research trends

• Compare different findings

• Identify gaps in knowledge

• Support a research question

• Inform evidence-based practice

• Provide background for a dissertation or research project

For example, if your topic is nurse-led patient education for diabetes management, your literature review may examine research about patient education, diabetes self-management, nursing interventions, patient outcomes, and barriers to effective education.

The goal is not to describe every article published about diabetes. Instead, the review should focus on evidence that directly relates to your specific topic and research question.

Why Is a Literature Review Important in Nursing?

Nursing practice depends heavily on reliable evidence. A literature review helps students and researchers understand the existing evidence before making conclusions or proposing further research.

A well-written literature review can help you:

• Understand your research topic

• Identify important concepts

• Find established research findings

• Compare different approaches

• Identify disagreements in the literature

• Recognise research gaps

• Avoid unnecessary duplication of research

• Support an evidence-based argument

• Develop a focused research question

• Connect research with nursing practice

For nursing students, literature reviews also provide an opportunity to demonstrate critical thinking.

Literature Review vs Literature Summary

One of the most important things to understand is that a literature review is not simply a collection of summaries.

A summary tells the reader what a particular study found.

A literature review goes further by asking:

• How do studies compare?

• Do researchers agree?

• Why might their findings differ?

• What are the strengths of the evidence?

• What limitations exist?

• What themes appear across studies?

• What remains unknown?

• How does the evidence relate to nursing practice?

Example of a Basic Summary

“Study A found that patient education improved medication adherence.”

Example of Critical Literature Review Writing

“Several studies have reported improvements in medication adherence following structured patient education. However, the reported effects vary between patient populations, and differences in follow-up periods and intervention methods make direct comparison difficult.”

The second example demonstrates synthesis and analysis rather than simply reporting one study.

Step 1: Understand the Assignment

Before searching for research, carefully read your assignment instructions.

Determine:

• The required topic

• Word count

• Research question

• Number of sources required

• Required publication dates

• Required databases

• Referencing style

• Required headings

• Submission requirements

• Whether a specific literature review method is required

Your university may also specify whether the review should be narrative, systematic, integrative, or another type.

Understanding these requirements before researching can prevent unnecessary work.

Step 2: Choose a Focused Nursing Topic

If you can choose your own topic, select something relevant to nursing and narrow enough to analyse effectively.

Examples include:

• Nurse-led diabetes education

• Pressure injury prevention

• Medication errors

• Nurse burnout

• Patient falls

• Pain management

• Infection prevention

• Nurse-patient communication

• Patient education

• Telehealth nursing

• Mental health nursing

• Postoperative care

• Chronic disease management

Avoid choosing topics that are too broad.

Too Broad

“Diabetes and nursing”

More Focused

“The effectiveness of nurse-led education in improving self-management among adults with type 2 diabetes.”

A focused topic makes it easier to identify relevant research and organise the literature.

Step 3: Develop a Research Question

A clear research question gives your literature review direction.

For example:

“How effective are nurse-led educational interventions in improving self-management among adults with type 2 diabetes?”

Your research question should be:

• Clear

• Focused

• Researchable

• Relevant to nursing

• Appropriate for the assignment

• Narrow enough to address within the word count

Avoid questions that cover too many unrelated issues.

Step 4: Use PICO When Appropriate

For clinical and intervention-based questions, PICO can help create a focused research question.

PICO stands for:

• P – Population: Who is being studied?

• I – Intervention: What intervention is being considered?

• C – Comparison: What is the intervention being compared with?

• O – Outcome: What outcome is being examined?

For example:

Population: Adults with type 2 diabetes
Intervention: Nurse-led education
Comparison: Usual care
Outcome: Self-management

This can help you identify appropriate keywords for your literature search.

PICO is useful for many clinical questions, but it is not required for every type of nursing literature review.

Step 5: Identify Keywords

Once you have a topic and research question, identify important keywords.

For a topic about nurse-led diabetes education, keywords might include:

• Type 2 diabetes

• Diabetes education

• Nurse-led education

• Patient education

• Self-management

• Diabetes management

• Nursing intervention

• Patient outcomes

Think about synonyms as well.

For example:

“Patient education” OR “health education”

Using alternative terms can help you find more relevant research.

Step 6: Search Academic Databases

Use reliable academic databases to locate research.

Depending on your institution, useful databases may include:

• PubMed

• CINAHL

• Cochrane Library

• Scopus

• Web of Science

• Google Scholar

• University library databases

CINAHL is particularly relevant to nursing and allied health literature, while PubMed provides extensive biomedical and healthcare research.

Use your university's library resources when possible because they may provide access to full-text journal articles.

Step 7: Use Search Operators

Search operators can help make database searches more precise.

AND

Use AND to combine concepts.

Example:

“Type 2 diabetes” AND “nurse-led education”

This usually narrows the search.

OR

Use OR to include synonyms.

Example:

“patient education” OR “health education”

This can broaden your search.

NOT

Use NOT when you need to exclude an unwanted concept.

Example:

diabetes AND nursing NOT veterinary

Use NOT carefully because it can accidentally exclude relevant research.

Step 8: Set Inclusion and Exclusion Criteria

Inclusion and exclusion criteria help determine which sources should be considered for your review.

Possible Inclusion Criteria

You might include studies that:

• Focus on your target population

• Address your research question

• Are published in peer-reviewed journals

• Are within a defined publication period

• Are available in an appropriate language

• Examine the relevant intervention or outcome

Possible Exclusion Criteria

You might exclude studies that:

• Do not address the research question

• Focus on an unrelated population

• Are outside the selected date range

• Are not relevant to nursing

• Do not provide sufficient information

• Duplicate another publication

The criteria should be appropriate for your assignment and review method.

Step 9: Screen Your Search Results

Database searches may produce hundreds or thousands of results.

You do not need to read every article in full.

Start by reviewing:

1. Titles

2. Abstracts

3. Keywords

4. Publication information

Remove obviously irrelevant studies.

Then read the full text of the studies that appear relevant.

Keep a record of why studies were included or excluded if your assignment requires a formal review process.

Step 10: Evaluate the Quality of Sources

Not every research article provides equally strong evidence.

Evaluate each source carefully.

Consider:

• Research design

• Sample size

• Study population

• Data collection methods

• Measurement methods

• Potential bias

• Research setting

• Follow-up period

• Limitations

• Relevance to your research question

You should also consider whether the article is peer-reviewed and whether the research is sufficiently current for your topic.

Step 11: Take Organised Research Notes

Do not rely on memory while reading multiple articles.

Create a research table.

Author/YearResearch TopicMethodMain FindingsLimitationsRelevanceStudy APatient educationQuantitativeImproved knowledgeSmall sampleHighStudy BNurse-led interventionRCTImproved self-managementShort follow-upHighStudy CDigital educationQualitativePositive patient experiencesLimited settingModerate

This table can help you identify patterns and differences across studies.

It also makes writing the literature review much easier.

Step 12: Identify Themes

After reading your sources, look for common themes.

Suppose you are reviewing research on nurse-led diabetes education.

Possible themes might include:

Theme 1: Patient Knowledge

Research examining whether education improves understanding of diabetes.

Theme 2: Self-Management

Studies investigating whether education changes patient behaviour.

Theme 3: Medication Adherence

Evidence examining whether educational interventions influence medication use.

Theme 4: Long-Term Outcomes

Research examining whether benefits continue over time.

Organising the review around themes is often more effective than discussing one article at a time.

Step 13: Compare Studies

A strong literature review compares findings.

Ask:

• Do studies agree?

• Do some studies report different findings?

• What explains the differences?

• Are populations different?

• Were different interventions used?

• Were different outcomes measured?

• Were follow-up periods different?

For example:

“Several studies reported improved self-management following nurse-led education, although the magnitude of improvement varied. Differences in intervention duration, patient populations, and follow-up periods may partly explain the variation.”

This demonstrates synthesis.

Step 14: Identify Research Gaps

One of the main purposes of a literature review is to identify what remains unknown.

A research gap may exist when:

• Very few studies examine a topic

• Existing studies produce conflicting findings

• A population is under-researched

• Studies have methodological limitations

• Long-term outcomes have not been adequately examined

• Research has focused on one healthcare setting

• Existing evidence is outdated

For example:

“Although research suggests that nurse-led education can improve short-term diabetes knowledge, evidence regarding sustained changes in self-management remains less consistent.”

This identifies an area where further research may be useful.

Avoid saying that “no research exists” unless your search is comprehensive enough to support that conclusion.

Step 15: Create a Literature Review Outline

Before writing, organise the information into a logical structure.

A typical nursing literature review may include:

1. Introduction

2. Background

3. Search strategy or methodology, when required

4. Main themes

5. Critical analysis

6. Research gaps

7. Implications for nursing

8. Conclusion

9. References

The exact structure depends on your assignment.

Step 16: Write the Introduction

The introduction should establish the context of your literature review.

It can include:

• Background to the topic

• Importance of the nursing issue

• Scope of the review

• Research question

• Purpose of the review

• Brief explanation of the organisation

For example, if your review examines pressure injury prevention, explain why pressure injuries are an important nursing concern before introducing the focus of your review.

Keep the introduction focused.

Step 17: Explain the Search Strategy

Some nursing literature reviews require a description of how the literature was identified.

You may need to explain:

• Databases searched

• Keywords used

• Search operators

• Publication date range

• Inclusion criteria

• Exclusion criteria

• Types of studies considered

For example:

“Relevant literature was identified through searches of nursing and healthcare databases using combinations of keywords relating to nurse-led education, diabetes self-management, and patient outcomes.”

If your assignment requires a formal systematic or scoping review methodology, follow the specific reporting requirements provided by your institution.

Step 18: Write the Main Body by Themes

Organise the main body around themes rather than individual articles.

For example:

Theme 1: Effect on Patient Knowledge

Discuss several studies together.

Theme 2: Effect on Self-Management

Compare evidence from different studies.

Theme 3: Barriers to Effective Education

Analyse factors that may affect outcomes.

Theme 4: Implications for Nursing Practice

Explain what the evidence means for nurses.

This structure helps create a coherent argument.

Step 19: Use Critical Analysis

Critical analysis is essential.

Do not simply write:

“Study A found that education improved patient knowledge. Study B also found an improvement.”

Instead, analyse the evidence:

“Although several studies report improvements in patient knowledge following structured education, differences in intervention design and measurement tools make it difficult to determine which educational approach is most effective.”

Critical analysis can involve:

• Comparing methodologies

• Evaluating study quality

• Discussing limitations

• Examining conflicting findings

• Considering applicability

• Identifying possible sources of bias

• Explaining clinical significance

Step 20: Synthesise the Evidence

Synthesis means bringing evidence from multiple sources together to create a broader understanding.

A useful literature review does not treat every study as an isolated piece of information.

For example:

“Across the reviewed studies, nurse-led education was generally associated with improvements in patient knowledge and self-management. However, differences in intervention intensity, follow-up duration, and outcome measurement suggest that the effectiveness of individual approaches may vary.”

This combines multiple findings into one analytical statement.

Step 21: Connect the Evidence to Nursing Practice

Your review should explain why the evidence matters to nurses.

Depending on the topic, implications may include:

• Patient education

• Clinical assessment

• Nursing interventions

• Patient safety

• Communication

• Care planning

• Health promotion

• Chronic disease management

• Quality improvement

• Staff education

Do not make recommendations that go beyond what the evidence supports.

Step 22: Discuss Limitations

A good literature review should acknowledge limitations.

Possible limitations include:

• Limited number of studies

• Small sample sizes

• Different study designs

• Different patient populations

• Inconsistent outcome measures

• Limited geographical representation

• Short follow-up periods

• Potential publication bias

• Language restrictions

Explaining these limitations demonstrates critical thinking.

Step 23: Write the Conclusion

The conclusion should summarise the overall evidence.

It should:

• Return to the research question

• Summarise the main themes

• Explain what the evidence shows

• Highlight important limitations

• Identify research gaps where appropriate

• Explain the relevance to nursing

Do not introduce completely new arguments in the conclusion.

Step 24: Reference Your Sources Correctly

Use the referencing style required by your institution.

Common styles include:

• APA

• Harvard

• Vancouver

Maintain accurate records of your sources while researching.

Make sure:

• Every borrowed idea is cited

• Direct quotations are clearly identified

• References are complete

• In-text citations match the reference list

• Formatting follows the required style

Avoid Plagiarism

Plagiarism can occur when students use another person's words or ideas without appropriate acknowledgement.

To avoid plagiarism:

• Take organised notes

• Paraphrase in your own words

• Cite the original source

• Use quotation marks for direct quotations

• Do not copy and change only a few words

• Keep your research notes separate from your own analysis

Your literature review should demonstrate your understanding and analysis of the research.

Common Mistakes in Nursing Literature Reviews

1. Summarising Every Article Separately

This creates a descriptive paper rather than a critical review.

2. Choosing an Extremely Broad Topic

A broad topic can produce too much information and prevent meaningful analysis.

3. Using Poor-Quality Sources

Avoid relying heavily on non-academic websites.

4. Ignoring Conflicting Evidence

If studies disagree, discuss the differences rather than selecting only evidence that supports your preferred argument.

5. Failing to Identify Research Gaps

A literature review should show what is known and what remains uncertain.

6. Using Outdated Research Without Explanation

Older research may be important, but consider whether newer evidence is available.

7. Weak Connection to Nursing

Make clear why the evidence matters for nursing practice.

8. Poor Referencing

Incorrect citations can reduce the academic quality of the paper.

Tips for Writing a Strong Nursing Literature Review

Use these practical tips:

1. Start with a focused research question.

2. Search multiple reliable academic databases.

3. Use a combination of keywords and synonyms.

4. Keep organised research notes.

5. Evaluate the quality of every important source.

6. Group research into themes.

7. Compare findings between studies.

8. Discuss conflicting evidence.

9. Identify research gaps.

10. Connect findings to nursing practice.

11. Avoid unnecessary repetition.

12. Reference sources accurately.

13. Leave enough time for editing and proofreading.

How Many Sources Should a Nursing Literature Review Have?

There is no universal number of sources that applies to every nursing literature review.

The appropriate number depends on:

• Word count

• Assignment requirements

• Topic complexity

• Availability of research

• Type of literature review

• University guidelines

Focus on finding enough relevant, high-quality evidence to answer the research question rather than trying to reach an arbitrary number.

How Recent Should Sources Be?

The appropriate publication period depends on the topic.

For rapidly changing healthcare topics, recent research may be particularly important.

However, older studies can still be relevant when they:

• Introduced an important theory

• Established foundational knowledge

• Remain influential

• Provide historical context

Follow your assignment instructions if a specific publication date range is required.

Narrative vs Systematic Literature Review

Not all literature reviews are conducted in the same way.

Narrative Literature Review

A narrative review provides a structured discussion of existing research and often focuses on themes, concepts, and critical analysis.

It is commonly used in academic assignments.

Systematic Literature Review

A systematic review follows a predefined and transparent methodology for identifying, selecting, evaluating, and synthesising research studies.

Systematic reviews generally require more detailed methods and reporting procedures.

Do not describe an assignment as a systematic review unless it actually follows an appropriate systematic methodology.

Frequently Asked Questions

Conclusion

Learning how to write a nursing literature review is an essential skill for nursing students and healthcare researchers. A successful literature review does more than collect information. It evaluates existing evidence, compares research findings, identifies important themes, recognises limitations, and highlights gaps in knowledge.

The process begins with a focused research question and a structured search for reliable evidence. After collecting relevant studies, organise them into meaningful themes and critically analyse how they relate to one another.

Most importantly, keep the focus on the research question and explain what the evidence means for nursing practice.

With regular practice, nursing students can develop stronger research, critical-thinking, and academic-writing skills. These skills are valuable not only for completing assignments but also for supporting evidence-based and patient-centred nursing care.
