"In general, scoping reviews are commonly used for 'reconnaissance' - to clarify working definitions and conceptual boundaries of a topic or field. Scoping reviews are therefore particularly useful when a body of literature has not yet been comprehensively reviewed, or exhibits a complex or heterogeneous nature not amenable to a more precise systematic review of the evidence.
While scoping reviews may be conducted to determine the value and probable scope of a full systematic review, they may also be undertaken... in and of themselves to summarize and disseminate research findings, to identify research gaps, and to make recommendations for the future research."
Using a standard or guideline will help you conduct your scoping review correctly.
Scoping review methodology has evolved over time. A number of key papers that were fundamental to this evolution are available on the Key historical papers tab of this box. These are not recommended to be used as current methodology, but can be useful to provide background and context.
Watch the video below, narrated by Dr Micah Peters, to learn how the scoping review methodology evolved (to 2017).

Current standards and guidelines:
The Joanna Briggs Institute's (JBI) approach is widely considered the standard. It aims to consolidate and build on earlier works describing scoping review methodologies. The Cochrane Collaboration follows a similar approach.
The steps below are based on Chapter 11 of the JBI Manual for Evidence synthesis.
This is the plan for your review.
