A guide to conducting systematic reviews.

What is a systematic review?

Systematic Review

A systematic review attempts to collect and analyze all evidence that answers a specific question.  The question must be clearly defined and have inclusion and exclusion criteria. A broad and thorough search of the literature is performed and a critical analysis of the search results is reported and ultimately provides a current evidence-based answer  to the specific question.

Why Do a Systematic Review?

  • Save clinicians and researchers valuable time
  • Take a large mass of literature and make concise sense of it
  • Objectively evaluate the quality of evidence on a topic
  • Resolve or highlight contradictions in the literature
  • Guide clinical decisions
  • Form the basis for practice guidelines and health care policy
  • Identify the need for additional research
  • Prevent unnecessary studies from being carried out

Other Types of Reviews

There are a wide variety of different types of reviews. For an excellent summary of 14 review types, see Grant MJ, Booth A. A typology of reviews: an analysis of 14 review types and associated methodologies. Health Info Libr J. 2009 Jun;26(2):91-108. PMID: 19490148.

Here are some common categories:

Narrative reviews: Broad perspective on topic, no specified search strategy, significant bias issues, may not evaluate quality of evidence

Systematic reviews: Comprehensive with minimized bias, based on specific question and criteria with a pre-planned protocol, evaluates quality of evidence

  • Based on randomized controlled clinical trials (RCTs) – Best evidence
  • Based on other types of clinical studies or literature – Best available evidence
  • Meta-analysis – A quantitative systematic review that applies statistical analysis

Scoping Reviews: An overview of the literature on a broader topic; often done to identify whether a systematic review is feasible or to identify the overall state of the literature. For detailed information on how to do a Scoping Review, check out the Joanna Briggs Institute Guidelines.
