Scoping Review Guide

What is a Scoping Review?

Scoping reviews can be used to determine the scope or coverage of a body of literature on a given topic. They are typically used for broad questions and can help identify and map the available evidence. A meta-analysis is not usually part of a scoping review.

You may choose to conduct a Scoping Review:

  • To identify the types of available evidence in a given field
  • To clarify key concepts/definitions in the literature
  • To examine how research is conducted on a certain topic or field
  • To identify key characteristics or factors related to a concept
  • As a precursor to a systematic review (results from the scoping review can help create a more focused question suitable for a systematic review)
  • To identify and analyze knowledge gaps
