Operating room (OR) “black boxes”– which combine continuous monitoring of intraoperative data with video and audio recording of operative procedures – are increasingly used to improve clinical and team performance. This study surveyed OR professionals in Denmark and Canada about safety attitudes and privacy concerns regarding OR black box use. Participants were primarily concerned with safety climate and teamwork in the OR and use of OR black boxes can support learning and improvements in these areas. The North American cohort expressed more concerns about data safety.
