What Is a Nursing Literature Review?
A literature review is a comprehensive, critical analysis of existing research on a specific nursing topic. Unlike an annotated bibliography that simply summarizes sources, a literature review synthesizes findings across multiple studies to identify patterns, contradictions, and gaps in current knowledge.
In nursing education, literature reviews serve multiple purposes: they form the foundation of research proposals, justify evidence-based practice changes, and demonstrate your ability to engage critically with scholarly work. Whether you're writing a standalone assignment or Chapter 2 of your dissertation, mastering the literature review is essential.
Types of Literature Reviews in Nursing
Narrative Literature Review
The most common type in nursing coursework. Provides a broad overview of a topic without systematic search protocols. Useful for exploring concepts and identifying research directions.
Systematic Review
Follows a rigorous, predefined protocol to identify, appraise, and synthesize all relevant studies. Includes PRISMA flow diagrams and explicit inclusion/exclusion criteria. Common for DNP and PhD work.
Integrative Review
Combines diverse methodologies (quantitative, qualitative, theoretical) to provide comprehensive understanding. Popular in nursing for examining complex phenomena like patient experience or care quality.
Scoping Review
Maps the breadth of literature on an emerging topic. Useful when the research area is new or diverse, helping identify what types of evidence exist before conducting a systematic review.
Step 1: Define Your Research Question
A focused research question is the foundation of an effective literature review. Vague questions lead to unfocused reviews that overwhelm both you and your reader.
Use the PICOT Framework
- P - Population: Who are you studying?
- I - Intervention/Interest: What intervention or phenomenon?
- C - Comparison: What are you comparing it to?
- O - Outcome: What outcomes matter?
- T - Time: Over what time period?
Step 2: Search the Literature Systematically
Primary Nursing Databases
- CINAHL (Cumulative Index to Nursing and Allied Health Literature): The premier nursing database with over 5,700 journals indexed.
- PubMed/MEDLINE: Comprehensive biomedical database including nursing research.
- Cochrane Library: Gold standard for systematic reviews and meta-analyses.
- PsycINFO: Essential for mental health nursing topics.
- ProQuest Dissertations: Access to nursing dissertations and theses.
Develop Your Search Strategy
Use Boolean operators to refine your search:
- AND: Narrows results (nurse burnout AND patient safety)
- OR: Broadens results (nurse OR nursing OR RN)
- NOT: Excludes terms (nursing NOT veterinary)
- Truncation (*): Captures variations (nurs* finds nurse, nurses, nursing)
Apply Inclusion and Exclusion Criteria
- Publication date range (typically last 5-10 years)
- Language (usually English)
- Study design (quantitative, qualitative, or both)
- Population characteristics
- Geographic setting if relevant
Step 3: Evaluate Source Quality
Not all research is created equal. Critically appraise each source using established frameworks.
Hierarchy of Evidence
From strongest to weakest:
- Systematic reviews and meta-analyses
- Randomized controlled trials (RCTs)
- Cohort studies
- Case-control studies
- Cross-sectional studies
- Case reports and expert opinion
Critical Appraisal Questions
- Is the research question clearly stated?
- Was the methodology appropriate for the question?
- Was the sample size adequate?
- Were results statistically significant and clinically meaningful?
- Are findings generalizable to your population of interest?
- Are there conflicts of interest?
Step 4: Organize Your Findings
Thematic Organization
Group studies by themes or concepts that emerge from the literature. This is the most common approach for nursing literature reviews.
Chronological Organization
Trace the evolution of research on your topic over time. Useful when showing how understanding has developed or when historical context matters.
Methodological Organization
Group studies by research design (all qualitative studies together, then quantitative). Useful for identifying methodological gaps in the literature.
Create a Literature Matrix
Use a spreadsheet to organize key information from each source: author, year, purpose, methodology, sample, findings, and limitations. This makes synthesis much easier.
Step 5: Synthesize - Don't Just Summarize
The difference between a good and excellent literature review is synthesis. You must weave studies together to tell a coherent story.
Weak Summary Approach
Strong Synthesis Approach
Synthesis Techniques
- Compare and contrast: "While Smith found X, Jones' larger sample revealed Y..."
- Identify patterns: "Across studies, three factors consistently emerge..."
- Note contradictions: "Findings are mixed, with some studies showing... while others..."
- Highlight gaps: "No studies to date have examined..."
Step 6: Identify Gaps and Justify Your Work
Every literature review should conclude by identifying what's missing. This justifies your research or practice change project.
Common Types of Gaps
- Population gaps: Most studies on elderly patients; none on young adults
- Setting gaps: Extensive hospital research; limited community/home health
- Methodological gaps: Quantitative data exists; qualitative understanding lacking
- Intervention gaps: Many descriptive studies; few testing interventions
- Outcome gaps: Short-term outcomes measured; long-term effects unknown

- Transformational leadership impact on nurse job satisfaction
- Barriers and facilitators to implementing evidence-based practice
- Organizational culture factors affecting nurse retention
Common Literature Review Mistakes
1. Relying Too Heavily on Secondary Sources
Use primary research articles, not textbooks or websites. Secondary sources can inform your understanding but shouldn't be your main citations.
2. Including Outdated Research
Healthcare evolves rapidly. Unless tracing historical developments, focus on literature from the past 5-7 years. Seminal works can be older.
3. Failing to Be Critical
Don't just accept findings at face value. Evaluate methodological quality and note limitations of the studies you review.
4. Losing Your Voice
Your analysis should drive the review. Don't let source citations overwhelm your own critical interpretation.

Get Literature Review HelpFrequently Asked Questions
How many sources should a nursing literature review include?
It depends on the assignment. A course paper might require 10-15 sources, while a dissertation literature review typically includes 50-100+ sources. Quality and relevance matter more than quantity.
How far back should I search?
Generally, focus on the past 5-10 years for current evidence. Include older seminal works that established foundational concepts in your area.
Can I include non-research sources?
Sparingly. Clinical guidelines, position statements, and theoretical papers can provide context, but primary research should form the core of your review.
