As an estimate, for a scoping review of 120 studies, it could take the equivalent of 2to 3 weeks for one person one person’s time for, 2 to 3 weeks to undertake the process of coding studies,including developing and testing a coding tool, although this varies between each review

On the basis of our experience of carrying out scoping reviews, we estimate that it takes between 5 and20 minutes to apply codes to one research abstract, depending on the detail of coding required. However, priorto this process, time is needed to develop a coding tool. This involves: considering what data would inform theresearch questions, and therefore deciding the facets upon which to code, and creating a coding tool that isunambiguous, and both broad and detailed enough to describe the dataset. The tool is often developed usinga sample of data, and examining pre-existing tools.
