MBSAQIP-Accredited centers must receive approval from an Institutional Review Board (IRB) in order to perform primary procedures that are not endorsed by the ASMBS. The IRB approval must be for performing the procedures, and not solely for data collection of outcomes from these procedures. In the event that an IRB determines a study protocol unnecessary for a primary procedure that is not endorsed by the ASMBS, a letter of exemption from the IRB is required to demonstrate compliance with MBSAQIP standards. Procedures and devices used for re-operative purposes do not require IRB approval or IRB exemption. However, the ASMBS recommends conforming to the endorsed procedure list when selecting procedures and devices for re-operative purposes whenever possible:
