Objective: The experience of stress is common among surgeons while working in the operating theatre (OT). Understanding and finding ways to mitigate this stress is important for optimizing surgical quality and maintaining clinician wellbeing. In this pilot study, we tested the feasibility and reported the outcomes of measuring the effect of background music on intra‐operative surgeon stress in the clinical environment. Methods: The effect of Music on the Operating Surgeon: A pilot Randomized crossover Trial (the MOSART study) was conducted over a 9‐month period in a single‐centre. Vascular and general surgeons acting as primary operators (POs) performing elective, general anaesthetic operations were included. The intervention was surgeon‐selected music, and the control was the absence of music. Outcome measures were feasibility (recruitment rate, practicability, and completeness of data), heart rate variability (HRV) indices, the Six‐Item State–Trait Anxiety Inventory (STAI‐6), and the Surgical Task‐load Index (SURG‐TLX). Results: Five POs performed 74 eligible randomized cases. The protocol was well tolerated, and no cases were abandoned. Data was incomplete in 8% of cases. The overall mean (SD) operative SURG‐TLX score was 48 (±22). Mean HR increased and RMSSD decreased significantly from baseline, suggesting reduced parasympathetic activity while operating. The presence of intra‐operative music was not found to affect the psychological or physiological outcomes. Conclusions: A music interventional study of this nature is feasible in the operating theatre environment, though no difference was found between in the music and non‐music conditions. Follow‐up research in a simulated environment with intensive physiological monitoring could be considered. [ABSTRACT FROM AUTHOR]
