Systematic reviews historically examined the effect or comparison of one treatment against another. Currently, a systematic review methodology can be used for topics involving effectiveness, diagnostic text accuracy, etiology, risk, incidence, prevalence, qualitative research, and more.
A scoping review maps the body of literature on a topic (often a broad topic) and identifies key concepts and research gaps. It may include data from any type of evidence and research methodology. It can be used as a standalone project or as a preliminary step to a systematic review.
Scoping reviews should have a protocol. This protocol can follow the PRISMA-Protocol extension. It should be registered with your institutional repository, figshare, or OSF.
An integrative review critiques and synthesizes the literature on a topic in an integrated way to generate new frameworks or perspectives on the topic. It allows for the inclusion of several study designs (e.g. experimental/nonexperimental, theoretical studies/empirical literature). It is also known as a “comprehensive review” or a “critical overview.”
A rapid review provides a rapid synthesis of knowledge about a policy or clinical practice issue and attempts to inform an evidence-based decision as soon as possible. It follows all of the stages of a systematic knowledge synthesis but may modify a stage to shorten the timescale.
A realist review looks to identify and explain social interventions or programs and the interactions between context, mechanisms, and outcomes for policy makers. It seeks to answer the question, “What works, for whom, in what circumstances?” It embraces multiple methods (both qualitative and quantitative).
An overview of reviews, or umbrella review, summarizes the evidence from multiple research syntheses into one accessible and usable document. It is based on high-quality, reliable systematic reviews on a specific health problem or topic, and it explores the consistency of findings across reviews
