RESUMO
OBJECTIVE: There is growing evidence supporting the benefits of preferred music on task performance, however there is a paucity of data regarding the potential impact on surgical and procedural learners. This study aims to assess the effects of nonpreferred music on surgical and procedural learners. DESIGN: This was a single-blinded, randomized crossover trial in which each participant completed a survey regarding their demographic information and music preferences. Each participant then completed 3 training tasks, and 2 repetitions of the evaluative task while listen to music. Tasks were completed using a Da Vinci Skills Simulator Si. SETTING: All tasks were completed in a live operating room at the University of Kansas Hospital, a tertiary care center. PARTICIPANTS: Medical students at the University of Kansas Medical Center were recruited by email to participate. In total, 31 medical students completed the experience. RESULTS: Thirty-one participants participated in this study. Group 2 (preferred music first, nonpreferred music second) showed no significant change in their test scores (72.73 vs 74.33, pâ¯=â¯0.34). However, Group 1 (nonpreferred music first, then preferred music) showed significant improvement between trial runs (70.31 vs 81.88, p < 0.001). There was no significant difference between the initial runs for each group. When analyzed irrespective of group assignment, there was a significant increase in scores for preferred music vs nonpreferred music (77.45 vs 72.26 pâ¯=â¯0.025). CONCLUSIONS: Participants showed expected improvement with task repetition. This improvement may have been offset by exposure to nonpreferred music during repeat runs. Our findings suggest that the impact of music was nearly as large as the impact of prior exposure to the task. This may have implications for environmental conditions during resident procedural training, especially early in residency training when new tasks are being introduced and the skill level of the learner is still low.
