Systematic Reviews in the Health Sciences
Should you consider another type of review?
Not all reviews are, or should be, systematic reviews. The following article offers a typology of different review types you may want to consider (see Table 1 for brief descriptions):
Grant M, Booth A. A typology of reviews: an analysis of 14 review types and associated methodologies. Health Information & Libraries Journal. 2009;26(2):91-108.
Some alternatives you might want to consider, depending on your time, scope, and resources, include:
Purpose: To modify the methods of systematic reviewing to generate an answer in a shorter time frame. Rapid reviews may take three weeks to six months to complete. They tend to be restricted to more easily-retrievable evidence; as a result they sacrifice some of the rigour typical of full systematic reviews.

Purpose: To situate the evidence in the context in which it is being applied - realizes that context influences the outcomes of an intervention. Often summed up as "what works, how, for whom, in what circumstances and to what extent?" (Greenhalgh et al., 2011).

Purpose: To assess the size and scope of available research literature, and identify gaps and research needs. The extent of the literature search depends on the reviewers time/scope constraints. While the quality of existing evidence may be described, there is usually not a formal quality appraisal process as with a systematic review.

Purpose: To synthesize the findings of several reviews around the same question. Quality appraisal may be of the reviews themselves, or of the studies contained within them.
