Providing a formal definition of scoping reviews as a type of evidence synthesis.

It is generally not recommended to use only one database because scoping reviews aim to comprehensively map the breadth and nature of evidence on a topic. Best practice, as recommended by the Joanna Briggs Institute (JBI) and other experts, is to conduct at least a limited initial search in two or more relevant databases to capture a wide range of studies. This helps reduce the risk of missing relevant literature, given that different databases index different journals and types of content. Additionally, comprehensive searching often involves iterative searching, including checking reference lists and grey literature, to ensure broad coverage. Using just one database risks bias and incomplete data capture, which is against the principles of a robust review.
