Evaluation of the Usefulness of Perioperative Pharmacist Audit and Feedback for General Anesthesia Surgery Patients

This study investigated the effects of perioperative pharmacist audit and feedback (PPAF) on drug utilization in patients undergoing general anesthesia at Ogaki Municipal Hospital. In PPAF, pharmacists documented medical records based on a checklist on pre- and postoperative days and provided necessary recommendations to the attending physician or anesthesiologist to ensure appropriate medication use. A public relation analysis was conducted on 1,639 cases following PPAF. Perioperative pharmacists made 215 recommendations to 208 patients (12.7％), with an acceptance rate of 84.7％. PPAF required approximately 3 hours of pharmacist work per day. The primary recommendations included the use of 5-HT3 receptor antagonists for the prevention of postoperative nausea and vomiting (PONV) (74 cases, 34.4％ of recommendations) and antimicrobial dose adjustments based on patient weight (73 cases, 34.0％).
