What Surgeons Should know About the Supervision of Certified Registered Nurse Anesthetists in Ohio 


OSMA has become aware that an increasing number of facilities—both larger health systems and smaller regional hospitals—have been implementing models where there is no anesthesiologist on site (either all of the time or during certain times, typically nights and weekends).

Ohio Law is very specific regarding the supervision of Certified Registered Nurse Anesthetists (CRNAs), a subset of advanced practice registered nurses (APNs), who do not have collaboration agreements like other APNs. They must always be under the supervision of a physician. Therefore, when an anesthesiologist is not physically present in the hospital and immediately available to the CRNA, the supervisory responsibility of the CRNA falls to the operating surgeon or Ob/Gyn. 

Some very important reminders/questions for surgeons and Ob/Gyns in Ohio to be aware:


Read the current provisions to supervision of CRNAs in Ohio.
