Scoping reviews involve the summarization and categorization of literature prepared to rapidly map the key concepts, types of evidence, and data gaps related to a defined research area by systematically searching, selecting, and presenting existing knowledge. A scoping review can be undertaken as a standalone product or in support of decision-making and may involve varying degrees of synthesis of the existing knowledge. Systematic review methodology and the OHAT Approach to Systematic Review and Evidence Integration also include the terms scoping and problem formulation as part of the decision-making and planning process for a systematic review. Scoping is the process of taking the initial background knowledge on a topic under consideration and seeking input from stakeholders and clients to understand the extent of interest in an evaluation topic or nomination, assessing the potential impact of conducting an evaluation, and identifying related activities that may already be underway. Problem formulation refers to the first step in the systematic review process in which an explicit definition or statement is reached on what is to be evaluated in an assessment and how it is to be evaluated.
