"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. 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:
Timeframe: ≤ 5 weeks (varies)
Question: More flexibility for broader questions, 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
