Hi Alexis,
At my institution NHS (or via IRAS) applications are all reviewed by my colleague and I as part of the sponsorship approval process prior to submission. There is no other internal review. Following approval, we remind the applicant(s) about annual reports, and review amendments etc, but there are all managed by me and my colleague alone. We as contacts on behalf of the institution sponsor keep complete records of all the documentation submitted and any correspondence with the REC/HRA etc. throughout the life course of the study. We decided that no other review was required as the NHS/HRA process is very rigorous. Does this help?
Would you find it useful for me to give you a call to have a chat about it in more detail?
With warm regards,
Alison
