The Association of periOperative Registered Nurses (AORN) publishes evidence-based, peer-reviewed guidelines for perioperative practice to promote patient safety, reduce infection risk, and standardize care in the perioperative setting. These guidelines cover topics including surgical attire, environmental cleaning, infection prevention, aseptic technique, patient positioning, medication safety, surgical site identification, anesthesia care, and specialized procedures. They are designed for perioperative nurses, surgical teams, and facility leaders to implement policy, education, and quality improvement.
