The impact of positive and negative intraoperative surgeons' leadership behaviors on surgical team performance.
The American Journal of Surgery(2018)
摘要
Background: The effects of surgeons' leadership on team performance are not well understood. The purpose of this study was to examine the simultaneous effects of transformational, passive, abusive supervision and over-controlling leadership behaviors by surgeons on surgical team performance. Methods: Trained observers attended 150 randomly selected operations at a tertiary care teaching hospital. Observers recorded instances of the four leadership behaviors enacted by the surgeon. Post-operatively, team members completed validated questionnaires rating team cohesion and collective efficacy. Multiple regression analyses were computed. Data were analyzed using the complex modeling function in MPlus. Results: Surgeons' abusive supervision was negatively associated with psychological safety (unstandardized B = -0.352, p < 0.01). Both surgeons' abusive supervision (unstandardized B = -0.237, p < 0.01), and over-controlling leadership (unstandardized B = -0.230, p < 0.05) were negatively associated with collective efficacy. Conclusions: This study is the first to assess the simultaneous effects of surgeons' positive and negative leadership behaviors on intraoperative team performance. Significant effects only surfaced for negative leadership behaviors; transformational leadership did not positively influence team performance. (C) 2017 Elsevier Inc. All rights reserved.
