We are planning a registry study of a particular patient population to understand outcome of medical management. The study involves retrospective data collection from patient records from multiple hospitals. There is no further follow-up planned in the study and so informed consent is also not applicable.
Therefore, we would like to consider central ethics committee approach at one center as the study falls in low to minimal risk category.
Is this as per routine practice or guidelines & requirements says something different?
Do we need to get approval from all the institutional ethics committees for such registry studies?
Is there any guidelines or reference to support central EC approach and not requiring approvals from all data collection centers for such studies?
Thanking you in anticipation.
