Not just a faster, cheaper systematic review

Beware: Shortcuts in a rapid review save time, but they may also sacrifice the quality of the review and, as a result, the accuracy of its conclusions. So, while this form of evidence synthesis may be justified in some circumstances, it is not a replacement for a robust systematic review. 

Decision-makers should think about how much risk they can, and should, tolerate as they start this process. It’s important to consider the potential consequences of missing key information or getting an incorrect answer. 

Decision-makers should also think about their level of comfort with the potential perception that a rapid review may be inadequate because it skipped certain elements of a systematic review.
