Background: The effect of playing background music on surgical outcomes has been controversial. This prospective case-control study aims to evaluate the impact of music tempo in general surgical settings.
Study design: Six hundred consecutive patients with nonmetastatic breast cancer receiving breast cancer surgery have been recruited since April 2017. Patients were then assigned to 3 arms in consecutive order. The surgeon operated without music in study arm A; the surgeon operated with slow music in study arm B; and in study arm C, the surgeon operated with fast background music. Patients' clinical records were reviewed by an independent blinded assessor.
Results: Baseline demographic data were comparable among the 3 study arms. Seven (3.5%) patients from study arm A developed minor complications (Clavien-Dindo class I and II); none developed major complications (Clavien-Dindo class III or above). Six (3.0%) patients from study arm B and C, respectively (slow/fast music groups), developed minor complications; none developed a major complication. Mean blood loss was also similar among the 3 study arms (5.1, 5.1, and 5.2 mL, respectively; p > 0.05). Operating time was significantly shorter in study arm C: 115 minutes (90-145), compared with 125 minutes (100-160) in study arm A (p < 0.0001) and 120 minutes (95-155) in study arm B (p = 0.0024). After a median follow-up of 40 months (3-56), 40 months (3-56), and 39.5 months (3-56), the local recurrence rates were 1.5%, 1%, and 1%, respectively (p > 0.05).
Conclusion: Playing music in the operating room is safe in general surgical settings in experienced hands.
