BACKGROUND: This study aimed to evaluate comments received by surgeons on an intraoperative 360-degree evaluation (i360) and their alignment with Non-Technical Skills for Surgeons (NOTSS). METHODS: The i360 assesses surgeons' intraoperative skills via feedback from perioperative staff. 88 academic surgeons underwent i360s. Inductive thematic analysis identified feedback themes and their alignment with NOTSS categories (leadership, communication and teamwork, decision-making, situation awareness). RESULTS: 699 evaluations had qualitative comments and 589 (84.3 %) included NOTSS-related concepts. Most fell within leadership (n = 371, 53.1 %) and communication and teamwork (n = 275, 39.3 %). Notable leadership themes included mentorship, professionalism, and respect for colleagues. Communication and teamwork themes were communicating case needs, intraoperative bedside manner, and team collaboration. Themes surrounding decision-making (n = 157, 22.5 %) were case bookings and patient care judgements, while situation awareness (n = 117, 16.7 %) included patience, rushing, and stress response. CONCLUSIONS: i360 surgeon feedback aligned with non-technical skills, indicating that perioperative staff are a valuable source of actionable insights.
