Systematic reviews and meta-analyses are among the highest levels of evidence in healthcare research. They require careful planning, transparent methodology and critical appraisal of published evidence.

This resource is designed to help nursing students understand the questions they should consider when planning or writing a systematic review or meta-analysis.

It does not provide a completed assignment or model answers.

Questions to Consider

When planning your systematic review, consider the following:

Research Question

  • How will you develop a focused research question?

  • Should you use PICO or PICo?

  • Is your question clinically relevant and answerable?

Literature Search

  • Which databases are appropriate?

  • How will you develop your search strategy?

  • Which inclusion and exclusion criteria will you apply?

Critical Appraisal

  • Should you use CASP or JBI?

  • Which appraisal tool is appropriate for each study design?

  • How will you assess risk of bias?

Evidence Synthesis

  • Will your review use narrative synthesis or meta-analysis?

  • How will heterogeneity be assessed?

  • Is a pooled analysis appropriate?

Reporting

  • How will you follow PRISMA 2020?

  • Will you register your protocol on PROSPERO?

  • How will you report excluded studies?

Discussion

  • How will you interpret the findings?

  • What are the strengths and limitations of the evidence?

  • How do your findings relate to current nursing practice?

Conclusion

  • Does your review answer the original research question?

  • What recommendations can you make for nursing practice and future research?
