The importance of leadership is recognized in surgery, but the specific impact of leadership style on team behavior is not well understood. In other industries, leadership is a well-characterized construct. One dominant theory proposes that transactional (task-focused) leaders achieve minimum standards and transformational (team-oriented) leaders inspire performance beyond expectations.
We videorecorded 5 surgeons performing complex operations. Each surgeon was scored on the Multifactor Leadership Questionnaire, a validated method for scoring transformational and transactional leadership style, by an organizational psychologist and a surgeon researcher. Independent coders assessed surgeons' leadership behaviors according to the Surgical Leadership Inventory and team behaviors (information sharing, cooperative, and voice behaviors). All coders were blinded. Leadership style (Multifactor Leadership Questionnaire) was correlated with surgeon behavior (Surgical Leadership Inventory) and team behavior using Poisson regression, controlling for time and the total number of behaviors, respectively.
All surgeons scored similarly on transactional leadership (range 2.38 to 2.69), but varied more widely on transformational leadership (range 1.98 to 3.60). Each 1-point increase in transformational score corresponded to 3 times more information-sharing behaviors (p < 0.0001) and 5.4 times more voice behaviors (p = 0.0005) among the team. With each 1-point increase in transformational score, leaders displayed 10 times more supportive behaviors (p < 0.0001) and displayed poor behaviors 12.5 times less frequently (p < 0.0001). Excerpts of representative dialogue are included for illustration.
We provide a framework for evaluating surgeons' leadership and its impact on team performance in the operating room. As in other fields, our data suggest that transformational leadership is associated with improved team behavior. Surgeon leadership development, therefore, has the potential to improve the efficiency and safety of operative care.
领导力在外科手术中的重要性已得到认可,但领导风格对团队行为的具体影响尚未得到充分理解。在其他行业,领导力是一个有明确特征的概念。一种主流理论认为,交易型(以任务为导向)领导者能达到最低标准,而变革型(以团队为导向)领导者能激发超出预期的表现。
我们对5位进行复杂手术的外科医生进行了录像。由一位组织心理学家和一位外科医生研究员根据多因素领导力问卷对每位外科医生进行评分,该问卷是一种用于评估变革型和交易型领导风格的有效方法。独立编码员根据外科领导行为量表和团队行为(信息共享、合作及表达行为)对外科医生的领导行为进行评估。所有编码员均不知情。使用泊松回归分析领导风格(多因素领导力问卷)与外科医生行为(外科领导行为量表)及团队行为之间的相关性,并分别控制时间和行为总数。
所有外科医生在交易型领导方面得分相近(范围为2.38至2.69),但在变革型领导方面得分差异更大(范围为1.98至3.60)。变革型得分每增加1分,团队中的信息共享行为增加3倍(p < 0.0001),表达行为增加5.4倍(p = 0.0005)。变革型得分每增加1分,领导者表现出的支持行为增加10倍(p < 0.0001),不良行为出现频率降低12.5倍(p < 0.0001)。文中还包含了代表性对话的节选以供说明。
我们提供了一个评估外科医生领导力及其对手术室团队绩效影响的框架。与其他领域一样,我们的数据表明变革型领导与改善团队行为相关。因此,外科医生领导力的发展有可能提高手术护理的效率和安全性。
