Which factors are considered in determining if a study is "expedited"?

In determining whether a study is categorized as "expedited," the primary consideration is the level of risk and the nature of the research procedures involved. The expedited review process is designed for studies that present minimal risk to participants and involve specific types of research methods that are deemed to have a lower potential for harm. This can include studies like those utilizing existing data, surveys, or certain behavioral interventions that do not pose significant risks to subjects.

Factors such as the size of the research team, the funding source, and the geographical location of the study do not fundamentally influence the expedited classification. Instead, they may be relevant considerations for other aspects of the research protocol or ethics review process, but the core determinants of expedited review focus primarily on the associated risks and procedural characteristics.
