A systematic review in nursing follows the same rigorous methodology as any health sciences systematic review but incorporates frameworks and databases specific to nursing practice, education, and research. Nursing systematic reviews are essential for building the evidence base that informs clinical decision-making, nursing education curricula, policy development, and patient care standards. The Joanna Briggs Institute and Cochrane Collaboration provide the two primary methodological frameworks used in nursing evidence synthesis.
Nursing research has unique characteristics that affect how systematic reviews are designed and conducted. Nursing studies frequently use qualitative, mixed-methods, and quasi-experimental designs alongside randomized controlled trials. Patient experiences, care delivery processes, and nursing interventions often require synthesis approaches beyond traditional meta-analysis. This guide covers the specific considerations, databases, frameworks, and publication strategies that nursing researchers need to conduct and publish high-quality systematic reviews.
Why Systematic Reviews Matter in Nursing
Evidence-based nursing practice depends on synthesized evidence, not individual studies. A single randomized controlled trial or qualitative study provides one data point. A systematic review aggregates all available evidence on a clinical question, providing a comprehensive picture that individual studies cannot offer. This is why systematic reviews sit at the top of the evidence hierarchy in nursing and are the foundation of clinical practice guidelines.
The nursing profession has increasingly prioritized evidence-based practice over the past two decades, moving from tradition-based and experience-based care decisions toward care informed by the best available research evidence. Systematic reviews are the bridge between primary research and bedside practice. Nursing organizations including the American Nurses Association, the Royal College of Nursing, and the International Council of Nurses all recognize systematic reviews as the gold standard for evidence synthesis.
For nurse researchers, conducting a systematic review also builds methodological expertise, establishes research credibility, and contributes to the profession's knowledge base. Published nursing systematic reviews are highly cited because they serve as reference points for clinical guidelines, curriculum development, and policy decisions.
Choosing the Right Methodology: JBI vs Cochrane
The two dominant frameworks for nursing systematic reviews are the Joanna Briggs Institute (JBI) methodology and the Cochrane methodology. While both produce rigorous evidence syntheses, they differ in scope and approach.
JBI Methodology
The JBI is an international research organization based at the University of Adelaide that specializes in evidence-based healthcare with particular strength in nursing and allied health. JBI provides methodology for nine types of systematic reviews:
- Effectiveness reviews (interventions, similar to Cochrane)
- Qualitative reviews (using meta-aggregation)
- Mixed-methods reviews (combining quantitative and qualitative evidence)
- Prevalence and incidence reviews
- Scoping reviews (using PRISMA-ScR)
- Text and opinion reviews
- Diagnostic test accuracy reviews
- Economic evaluation reviews
- Umbrella reviews (reviews of systematic reviews)
JBI methodology is particularly valuable for nursing because it accommodates the qualitative and mixed-methods research designs common in nursing scholarship. The JBI Manual for Evidence Synthesis provides step-by-step guidance for each review type.
Cochrane Methodology
The Cochrane Collaboration focuses primarily on reviews of healthcare interventions using quantitative methods. Cochrane reviews follow the methodology outlined in the Cochrane Handbook for Systematic Reviews of Interventions and are considered the gold standard for intervention effectiveness reviews.
Cochrane methodology is appropriate for nursing reviews that focus on clinical interventions with measurable outcomes, particularly when randomized controlled trials are available and meta-analysis is the intended synthesis approach.
| Feature | JBI | Cochrane |
|---|---|---|
| Review types | 9 types including qualitative | Primarily interventions |
| Qualitative synthesis | Meta-aggregation | Limited support |
| Mixed methods | Supported | Not standard |
| Database | JBI EBP Database | Cochrane Library |
| Registration | JBI Systematic Review Register | Cochrane Review Groups |
| Quality tools | JBI Critical Appraisal Tools | RoB 2, ROBINS-I |
Essential Databases for Nursing Systematic Reviews
Database selection is critical for comprehensive evidence retrieval in nursing reviews. Missing a key database can result in excluding relevant nursing studies that are not indexed elsewhere.
CINAHL (Cumulative Index to Nursing and Allied Health Literature)
CINAHL is the single most important database for nursing systematic reviews and must be included in every nursing evidence synthesis. CINAHL indexes over 5,500 nursing and allied health journals, many of which are not indexed in MEDLINE. CINAHL uses its own controlled vocabulary (CINAHL headings) that includes nursing-specific terms not found in MeSH.
When building your Boolean search strategy for CINAHL, use both CINAHL headings and free-text terms. CINAHL's search interface differs from PubMed, so your search strategy will need to be translated for CINAHL-specific syntax.
MEDLINE (via PubMed)
MEDLINE is the primary biomedical database and should be searched alongside CINAHL. Many clinical nursing studies, particularly those involving pharmacological interventions or medical procedures, are indexed in MEDLINE. Use MeSH terms combined with free-text keywords for comprehensive retrieval.
Additional Databases
Depending on your topic, also consider:
- PsycINFO for mental health nursing, behavioral health, and psychology-related topics
- Embase for pharmacological and drug-related interventions
- Cochrane Central Register of Controlled Trials for RCTs
- JBI EBP Database for existing JBI evidence syntheses
- Education databases (ERIC) for nursing education topics
- Social science databases for community health nursing
Qualitative Evidence Synthesis in Nursing
One of the distinguishing features of nursing systematic reviews is the frequent inclusion of qualitative evidence synthesis. While medical systematic reviews predominantly focus on quantitative data and meta-analysis, nursing research often explores patient experiences, perceptions, meanings, and care processes that require qualitative synthesis methods.
Meta-Aggregation (JBI Approach)
Meta-aggregation is JBI's approach to synthesizing qualitative findings. It involves extracting findings from individual qualitative studies, assessing each finding for credibility (supported by direct quotes or field notes), categorizing similar findings, and aggregating categories into synthesized findings that can inform practice recommendations.
Meta-aggregation preserves the original meaning of qualitative findings rather than reinterpreting them, which is important for maintaining the integrity of participant voices in nursing research.
Thematic Synthesis
Thematic synthesis, developed by Thomas and Harden, involves coding the findings of primary qualitative studies, developing descriptive themes from the codes, and generating analytical themes that go beyond the original studies. This approach is widely used in nursing systematic reviews published in journals like the Journal of Advanced Nursing.
Mixed-Methods Synthesis
When your review includes both quantitative and qualitative studies, JBI methodology provides guidance for convergent or sequential mixed-methods synthesis. This allows you to integrate findings from RCTs about intervention effectiveness with qualitative findings about patient experiences of those interventions, providing a comprehensive evidence base for nursing practice.

Structuring Your Nursing Systematic Review
Defining Your Research Question
Use the PICO framework for intervention reviews:
- Population: Specific patient group or nursing context (e.g., "adult patients in intensive care units")
- Intervention: Nursing intervention or exposure (e.g., "nurse-led early mobilization protocols")
- Comparison: Alternative intervention or standard care
- Outcome: Patient outcomes, nursing outcomes, or process outcomes
For scoping reviews, use the PCC framework:
- Population: Target group
- Concept: Key concept being examined
- Context: Setting, geographic location, or cultural context
Developing Eligibility Criteria
Nursing systematic reviews should specify eligibility criteria that reflect the unique characteristics of nursing research:
- Study designs: Specify which designs to include. Nursing reviews often include quasi-experimental studies, pre-post designs, and qualitative studies alongside RCTs
- Settings: Specify healthcare settings (acute care, primary care, community, long-term care)
- Participants: Define the patient population and, where relevant, the nursing workforce characteristics
- Interventions: Clearly describe what constitutes a "nursing intervention" for your review
- Outcomes: Include both patient outcomes and nursing-sensitive outcomes
- Publication dates and language: State your date range and language restrictions
Protocol Registration
Register your protocol on PROSPERO for intervention reviews or the JBI Systematic Review Register for JBI reviews. Protocol registration demonstrates methodological rigor and prevents duplication. Follow the PRISMA-P checklist when writing your protocol.
Quality Assessment in Nursing Reviews
Nursing systematic reviews use validated critical appraisal tools to assess the methodological quality of included studies.
For RCTs: Use the RoB 2 tool (Cochrane) or JBI Critical Appraisal Checklist for Randomized Controlled Trials
For non-randomized studies: Use ROBINS-I or the Newcastle-Ottawa Scale
For qualitative studies: Use JBI Critical Appraisal Checklist for Qualitative Research (10-item checklist) or the CASP Qualitative Checklist
For cross-sectional studies: Use JBI Critical Appraisal Checklist for Analytical Cross-Sectional Studies
Quality assessment should be conducted by two independent reviewers with disagreements resolved through discussion or a third reviewer. Use our risk of bias visualization tool to create summary figures for your review.
Data Synthesis Options for Nursing Reviews
The synthesis approach depends on your included studies and research question:
- Meta-analysis for homogeneous quantitative studies. See our step-by-step meta-analysis guide and effect size calculation guide
- Narrative synthesis when studies are too heterogeneous for statistical pooling. Organize findings by outcome, intervention type, or population subgroup
- Meta-aggregation (JBI) for qualitative studies
- Vote counting is generally discouraged but sometimes used as a supplementary descriptive approach
- GRADE assessment for rating certainty of evidence in quantitative findings
Address heterogeneity transparently. Nursing interventions are often complex (involving multiple components, varying delivery formats, and different practice contexts), which naturally produces higher heterogeneity than pharmacological interventions.
