To study surgical teaching captured on film and analyze it at a fine level of detail to categorize physical teaching behaviors.
We describe live, filmed, intraoperative nonverbal exchanges between surgical attending physicians and their trainees (residents and fellows). From the films, we chose key teaching moments and transcribed participants' utterances, actions, and gestures. In follow-up interviews, attending physicians and trainees watched videos of their teaching case and answered open-ended questions about their teaching methods. Using a grounded theory approach, we examined the videos and interviews for what might be construed as a teaching behavior and refined the physical teaching categories through constant comparison.
We filmed 5 cases in the operating suite of a university teaching hospital that provides gynecologic surgical care.
We included 5 attending gynecologic surgeons, 3 fellows, and 5 residents for this study.
More than 6 hours of film and 3 hours of interviews were transcribed, and more than 250 physical teaching motions were captured. Attending surgeons relied on actions and gestures, sometimes wordlessly, to achieve pedagogical and surgical goals simultaneously. Physical teaching included attending physician-initiated actions that required immediate corollary actions from the trainee, gestures to illustrate a step or indicate which instrument to be used next, supporting or retracting tissues, repositioning the trainee's instruments, and placement of the attending physicians' hands on the trainees' hands to guide them. Attending physicians often voiced surprise at the range of their own teaching behaviors captured on film. Interrater reliability was high using the Cohen κ, which was 0.76 for the physical categories.
Physical guidance is essential in educating a surgical trainee, may be tacit, and is not always accompanied by speech. Awareness of teaching behaviors may encourage deliberate teaching and reflection on how to innovate pedagogy for the teaching operating room.
研究拍摄下来的外科手术教学过程,并进行精细的细节分析,以便对实际教学行为进行分类。
我们描述了外科主治医师与其学员(住院医师和专科医师)在手术过程中的现场、拍摄的非语言交流。从影片中,我们选取了关键教学时刻,并记录了参与者的言语、动作和手势。在后续访谈中,主治医师和学员观看了他们教学案例的视频,并回答了关于他们教学方法的开放式问题。我们采用扎根理论方法,检查视频和访谈内容,找出可能被视为教学行为的内容,并通过不断比较来完善实际教学类别。
我们在一家提供妇科手术护理的大学教学医院的手术室拍摄了5个病例。
本研究纳入了5名妇科外科主治医师、3名专科医师和5名住院医师。
转录了超过6小时的影片和3小时的访谈内容,捕捉到了250多个实际教学动作。主治医师依靠动作和手势,有时无需言语,就能同时实现教学和手术目标。实际教学包括主治医师发起的动作,这些动作要求学员立即做出相应动作;用手势说明一个步骤或指示接下来要用的器械;支撑或牵拉组织;重新放置学员的器械;以及将主治医师的手放在学员手上以指导他们。主治医师常常对影片中捕捉到的自己丰富多样的教学行为感到惊讶。使用科恩κ系数,评分者间信度很高,实际教学类别为0.76。
实际指导对外科手术学员的教育至关重要,可能是隐性的,且并不总是伴随着言语。了解教学行为可能会促进有意识的教学,并促使人们思考如何在教学手术室中创新教学方法。
