 Rapid reviews are a type of systematic review that seek to synthesize evidence quickly compared to traditional systematic reviews. They vary widely in terms of the amount of time they take to complete, ranging from three weeks to six months. Various methods have been employed to speed up the process, including limiting the scope of the literature search, using fewer databases, and employing one reviewer for each phase of the review. These methods can introduce biases into the review process, such as missing relevant information during the literature search and data extraction phases. Additionally, the use of different methods for different phases of the review can make it difficult to compare the results of different rapid reviews. Despite this, there is a growing body of evidence suggesting that rapid reviews can produce reliable and valid results when conducted properly.
