An IRB that is conducting continuing review of research should be familiar with, and have access to, all IRB records related the research, including those associated with the initial review and approval and any other previous reviews, including ad hoc and scheduled continuing reviews and any reviews of amendments to the research or unanticipated problems. For continuing review of research at a convened meeting, IRB members should receive appropriate materials sufficiently in advance of the meeting to allow adequate time for review.
