Not all research questions are a good fit for systematic reviews. There are other review types that employ thorough, documented search strategies. Here are a few common examples:

Scoping Review

The purpose of a scoping review is to assess the potential size and scope of available literature for a research question. Scoping reviews can be useful if you have a broad question and would like to gain a better sense of major themes or topics. The end goal can be the scoping review itself, or you may be able to use the findings from a scoping review to create a more well-defined research topic for a systematic review. 

Rapid Review

A rapid review employs many of the same methods used for systematic reviews, but is usually completed in a shorter span of time. Due to time constraints, the search strategy used may be less comprehensive than traditional systematic reviews. Grey literature might not be included either. This type of review is typically undergone for urgent clinical decisions or emerging needs.
