Rapid Evidence Review, Rapid Evidence Assessment, Rapid Systematic Review, Expedited Review, Rapid Evidence Summary
"Rapid reviews are a form of evidence synthesis that may provide more timely information for decision making compared with standard systematic reviews." (AHRQ) The methods of conducting rapid reviews varies widely, and are typically done in less than 5 weeks. Often policy makers require a short deadline and a systematic review for synthesizing the evidence is not practical. A rapid review speeds up the systematic review process by omitting stages of the systematic review making it less rigorous.
Rapid Reviews are best designed for:
New or emerging research topics, updates of previous reviews, critical topics, to assess what is already known about a policy or practice using some systematic review methods.
Timeframe: ≤ 5 weeks (varies) *Varies beyond the type of review. Depends on many factors such as but not limited to: resources available, the quantity and quality of the literature, and the expertise or experience of reviewers" (Grant et al. 2009)
Question: Narrow question, may use PICO
Sources and searches: Sources are limited due to time constraints of searching, however still uses transparent and reproducible search methods.
Selection: Based on inclusion/exclusion criteria
Appraisal: Critical and rigorous but time limited
Synthesis: Descriptive summary or categorization of data, may still be quantitative
