Objective:The purpose of this article is to clearly describe how to develop a robust and detailed scoping review protocol, which is the first stage of the scoping review process. This paper provides detailed guidance and a checklist for prospective authors to ensure that their protocols adequately inform both the conduct of the ensuing review and their readership.Introduction:Scoping reviews are a common approach to evidence synthesis for researchers, clinicians, and policymakers across a variety of fields. Scoping reviews are not concerned with making analytical comparisons based on pooling results data from multiple primary sources of evidence, but rather on collating and describing the evidence and presenting the summation in a clearly illustrated format. Methods for undertaking and reporting scoping reviews continue to be refined. Some prospective reviewers may be uncertain how to plan, structure, and report scoping review protocols, as there is little or no specific guidance for scoping review protocols yet available.Methods:This guidance was developed by members of the JBI Scoping Review Methodology Group based on previous experience and expertise in developing scoping review and evidence synthesis methodologies, protocols, and reviews, as well as through experiences working with and guiding authors to develop scoping review protocols. Elements of a comprehensive scoping review protocol are outlined and explained in detail.Conclusion:Knowledge users of evidence syntheses rely on clear and transparent reporting to understand and use the results of published work to drive evidence-based improvements within health care and beyond. It is hoped that readers will be able to use this guidance when developing protocols to assist them in planning future scoping reviews and to carry them out with a high degree of transparency.

The objective of this scoping review is to examine and map the existing literature on the clinical application of the EOS imaging system and to identify related evidence gaps. Introduction:The EOS imaging system was originally developed to conduct imaging for medical conditions, such as scoliosis and anisomelia. However, recent research suggests that the modality has other clinical uses that may benefit patients via reduced radiation dose and, thus, improve patient safety.Inclusion criteria: This scoping review will consider all quantitative study designs, including systematic reviews and meta-analyses. Imaging phantom studies and conference abstracts will be excluded.Methods: Databases that will be searched include Embase, MEDLINE, CINAHL Complete, Scopus, Cochrane Library, Academic Search Premier, and OpenGrey. Relevant secondary material will be identified using citation searching (backwards and forwards) of included studies through Google Scholar. In addition, we will search by author name where more than 3 included studies from the same first author are identified. Articles published from 2003 in English, Danish, Norwegian, Swedish, French, and German will be included. Two independent reviewers will perform title/abstract screening, followed by full-text screening. Data extraction will include study type and design, age of participants, anatomical/physiological region, pathology, clinical endpoint, outcome measures, sample size, and clinical application. Data will be presented in tabular format and as a narrative summary.
