Video coaching has been found to be an effective teaching method because it incorporates many of the established principles of successful adult learning. The goal of our study was to assess the feasibility and effectiveness of using a point-of-view video camera (Google Glass) to improve the surgical skills education of orthopaedic surgery residents.
Forty-two residents from 4 institutions participated in a partially blinded randomized control trial performing an intra-articular distal tibial fracture reduction task while wearing Google Glass to record the performance. Participants underwent a structured coaching session with 20 participants (intervention group) using the recorded video to augment this session, and 22 participants (control group) receiving verbal coaching alone. The task was repeated again immediately after the coaching session. Performance was scored using an Objective Structured Assessment of Technical Skills checklist, Global Rating Scale, fluoroscopic usage, and reduction quality. A semistructured interview was then performed to assess experience of participants.
There was no significant difference (p > 0.05) seen in score improvement in the Objective Structured Assessment of Technical Skills checklist, Global Rating Scale, fluoroscopic usage, or reduction quality between the control and intervention groups. Thematic analysis of interview showed majority of participants found video coaching increased effectiveness in understanding of goals, developing techniques and strategies, and process of self-reflection. Their involvement was seen overall as a positive experience, with participants wanting to see more inclusion of video coaching within surgical education.
No difference in performance improvement between the 2 groups was seen, but majority of participants found the video coaching sessions valuable and could have potential beneficial role in education.
视频指导被发现是一种有效的教学方法，因为它结合了许多成功的成人学习的既定原则。我们的研究目的是评估使用观点视频摄像机（Google Glass）来提高矫形外科住院医师手术技能教育的可行性和有效性。
来自 4 个机构的 42 名住院医师参与了一项部分盲随机对照试验，在佩戴 Google Glass 记录表现的情况下进行关节内胫骨远端骨折复位任务。参与者接受了 20 名参与者（干预组）的结构化指导课程，使用录制的视频来增强此课程，而 22 名参与者（对照组）仅接受口头指导。指导课程后立即重复进行该任务。使用客观结构化评估技术技能检查表、总体评分、透视使用和复位质量来对表现进行评分。然后进行半结构化访谈，以评估参与者的经验。
在客观结构化评估技术技能检查表、总体评分、透视使用或复位质量方面，对照组和干预组的评分改善没有显著差异（p > 0.05）。访谈的主题分析表明，大多数参与者发现视频指导在理解目标、开发技术和策略以及自我反思过程方面增加了效果。他们的参与总体上被视为积极的体验，参与者希望看到更多的视频指导纳入手术教育。
两组之间在绩效改善方面没有差异，但大多数参与者发现视频指导课程有价值，并且在教育方面可能具有潜在的有益作用。
