The original scoping review framework proposed by Arksey and O’Malley [24, 25]

Stage		Description
1.	Identifying the research question	• As a guide to build a research strategy. • Should be wide enough to generate a breadth of coverage.
2.	Identifying relevant studies	• Via different sources: electronic databases, reference lists, hand-searching of key journals, existing networks, relevant organizations, and conferences. • Make decision about the coverage of the review in terms of time span and language (consider time and budget constraints).
3.	Study selection	• The criteria for the inclusion/exclusion criteria are device post hoc based on increasing familiarity with the subject matter through reading the studies. • Use an iterative team approach to select the studies and extract the data.
4.	Charting the data	• The work involves “charting” key items of the information obtained from the primary research reports being reviewed. • A data-charting form is developed and used to extract data from each study.
5.	Collating, summarizing, and reporting the results	• An analytic framework or thematic construction is used to provide an overview of the breadth of the literature but not a synthesis. • A numerical analysis of the extent and nature of the studies using tables and charts is presented. A thematic analysis is then presented. • Clarity and consistency are required when reporting results.
6.	Consultation exercise (optional)	• Provides opportunities for consumer and stakeholder involvement to suggest additional references and provide insights beyond those in the literature.
