Objective:
To determine if playing music would affect novice surgical trainees' ability to perform a complex surgical task.
Background:
The effect of music in the operating room (OR) is controversial. Some studies from the anesthesiology literature suggest that OR music is distracting and should be banned. Other nonblinded studies have indicated that music improves surgeons' efficiency with simple tasks.
Design/Methods:
A prospective, blinded, randomized trial of 19 novice surgical trainees was conducted using an in vitro model. Each trainee performed a baseline vascular anastomosis (VA) without music. Subsequently, they performed one VA with music (song validated to reduce anxiety) and one without, in random order and without prior knowledge of the study's purpose. The primary endpoint was a difference in differences from baseline with and without music with respect to time to completion, acceleration/deceleration (using a previously validated hand-tracking motion device), and video performance scoring (3 blinded experts using a validated scale). The participants completed a poststudy survey to gauge their opinions regarding music during tasks.
Results:
Overall, 57 VAs by 19 trainees were evaluated. Average time to completion was 11.6 minutes. When compared to baseline, time to completion improved for both the music group (p = 0.01) and no-music group (p = 0.001). When comparing music to no music, there was no difference in time to completion (p = 0.7), acceleration/deceleration (p = 0.3), or video performance scorings (p = NS). Among participants, 89% responded that they enjoy listening to music while performing tasks.
Conclusions:
Using three outcome measures, relaxing music did not improve the performance of novice surgical trainees performing a complex surgical task, and the music did not make their performance worse. However, nearly all trainees reported enjoying listening to music while performing tasks.
