Under what conditions can the expedited review process be utilized?

The expedited review process can be utilized when a study poses no more than minimal risk to participants. This aligns with the guidelines established for the expedited review process, which is designed to facilitate quicker evaluations of research that does not significantly impact the safety or well-being of research subjects. This is particularly important for studies that involve low-risk procedures or interventions, allowing researchers to efficiently advance their work while still ensuring ethical standards are upheld.

In contrast, some other conditions such as involving only written surveys, studying vulnerable populations, or situations where IRB approval is not required may not necessarily qualify a study for expedited review. While these factors can influence how a study may be reviewed, they do not directly relate to the fundamental criterion of minimal risk that governs the expedited review process.
