Briefing and debriefing are common practices for safety in high risk industries but are not systematically done in surgery. Regular debriefing of performance after operative surgery can greatly assist surgical trainees' development and help optimize learning from the limited time they spend in the Operating Room (OR). We developed and tested the NOTSS (Non-Technical Skills for Surgeons) behaviour rating system with subject matter experts. It allows surgeons to observe trainees' behaviour in the OR and provide them with structured feedback for improvement. This paper describes process of debriefing and the results of a pilot usability trial. The majority of participants reported that the NOTSS system was useful for debriefing trainees, provided a common language to discuss non-technical skills, and was a valuable adjunct to current assessment tools. Some surgeons found interpersonal skills more difficult to rate than cognitive skills. 73% felt that routine use of the system would enhance patient safety.
