Periop 101 is an online curriculum developed by AORN to help nurses new to the operating room master core perioperative competencies through modules containing readings, videos, and skills checklists. The goal of Periop 101 is to cultivate confident and well-prepared nurses centered around patient safety, in line with the IOM's recommendation for nurse residency programs. When used as a major component of an OR nurse residency program supplemented with preceptorship and skills labs, Periop 101 fosters the early adoption of AORN standards as the foundation for novice nurses' practice.
