The World Health Organization's (WHO) Surgical Safety Checklist (SSC) has resulted in improved surgical outcomes; however, use of the checklist varies. In this study, surgical personnel (surgeons, anesthesiologists, nurse anesthetists, surgical nurses, and assistant nurses) were surveyed about use of the SCC in their hospital, including who was responsible for ensuring its use. Although most groups reported it was not clear who was responsible for implementing the SSC prior to surgery, they believed it was the assistant nurse.
