 Scoping reviews are a type of evidence synthesis that focus on identifying existing knowledge rather than collecting new data. They are often used as a precursor to systematic reviews, but they can also be used independently to explore a topic or to identify gaps in the current literature. Scoping reviews are typically shorter and more focused than systematic reviews, and they do not include a meta-analysis. Instead, they use a variety of methods such as narrative synthesis, thematic analysis, and qualitative synthesis to summarize the findings from multiple sources. Scoping reviews are most appropriate when the goal is to understand the context of a particular issue, to identify key concepts, or to explore the feasibility of a research project.
