To undertake a scoping review is to understand the “lay of the land” on a topic.
Although there is no definitive definition of what a scoping review is, the general consensus amongst authors is that Mays et al (2001) best describes a scoping review.
According to Mays et al (2001), scoping reviews or scoping studies aim “to map rapidly the key concepts underpinning a research area and the main sources and types of evidence available, and can be undertaken as stand-alone projects in their own right, especially where an area is complex or has not been reviewed comprehensively before” (p. 194).
Arksey & O’Malley (2005) worked to expand on the definition set out by Mays et al and established a methodological framework in which researchers can apply to identify literature related to their topic and to date is the most utilised framework in undertaking a scoping review.
