An anesthesiologist who agrees to act as the sponsoring anesthesiologist of an anesthesiologist’s assistant shall adopt a written practice protocol that delineates the service that the anesthesiologist’s assistant is authorized to provide and the manner in which the anesthesiologist will supervise the anesthesiologist’s assistant. The anesthesiologist shall base the provisions of the protocol on consideration of relevant quality assurance standards, including being present at the most important times of the case and timely review of the patient’s anesthesia record at appropriate times during the course of the anesthetic procedure. The protocol must be reviewed by the anesthesiologist at least once a year.
