Scoping reviews serve to synthesize evidence and assess the scope of literature on a topic. Among other objectives, scoping reviews help determine whether a systematic review of the literature is warranted.
Systematic reviews of systematic reviews
Rapid reviews omit parts of the systematic review process to speed up the review process.
Integrative reviews are most often seen in the nursing discipline.
Living Systematic Reviews
Living systematic reviews are continually updated reviews that may be used to synthesize rapidly evolving areas of research.
The Cochrane Collaboration has produced a detailed handbook for researchers working on Cochrane reviews. Much of the guidance in the handbook is applicable to those working on systematic reviews.
