Coronavirus disease 2019 created unintended but significant experiential barriers for surgical learners to interact at the bedside for teaching/case presentations. We hypothesized that an international grand rounds using the Microsoft HoloLens 2 extended reality (XR) headset would create an improved bedside-learning experience compared to traditional grand rounds formats.
From December 2020 to March 2021, the world's first 2 international mixed reality grand rounds events using the HoloLens 2 headset were held, broadcasting transatlantically (between the University of Michigan and the Imperial College of London) bedside rounding experiences on 5 complex surgical patients to an international audience of 325 faculty, residents, and medical trainees. Participants completed pre- and post-event surveys to assess their experience.
Of the 325 participants, 267 (80%) completed pre-surveys, and 95 (29%) completed both the pre- and post-surveys. Respondents (average age, 38 y; 44% women, 56% men; 211 US, 56 UK) included 92 (34%) medical students and residents and 175 faculty and staff. In the pre-event survey, 76% had little or no earlier experience with XR devices, and 94% thought implementation of XR into medical curricula was valuable. In the post-survey, 96% thought telerounding using XR technology was important for the current era, and 99% thought the ability to visualize the examination, imaging, and laboratory results at bedside via XR rounding was highly valuable and that this format was superior to traditional grand rounds.
Almost all of the participants in the mixed reality international grand rounds felt the immersive XR experiences-allowing visualization of clinical findings, imaging, and laboratory results at the patient's bedside-were superior to a traditional grand rounds format, and that it could be a valuable tool for surgical teaching and telerounding.
2019 年冠状病毒病给外科学习者在床边进行教学/病例汇报带来了意想不到的重大体验障碍。我们假设，使用 Microsoft HoloLens 2 扩展现实 (XR) 耳机进行国际大查房将比传统大查房形式创造更好的床边学习体验。
2020 年 12 月至 2021 年 3 月，世界上首次使用 HoloLens 2 耳机进行了 2 次国际混合现实大查房，向 325 名教师、住院医师和医学实习生的国际观众转播了 5 名复杂手术患者的跨大西洋床边查房体验（密歇根大学和伦敦帝国理工学院之间）。参与者完成了会前和会后的调查，以评估他们的体验。
在 325 名参与者中，有 267 名（80%）完成了会前调查，95 名（29%）完成了会前和会后调查。受访者（平均年龄 38 岁；44%女性，56%男性；211 名来自美国，56 名来自英国）包括 92 名（34%）医学生和住院医师以及 175 名教师和工作人员。在会前调查中，76%的人几乎没有或没有以前使用 XR 设备的经验，94%的人认为将 XR 纳入医学课程是有价值的。在会后调查中，96%的人认为使用 XR 技术远程查房对于当前时代很重要，99%的人认为通过 XR 查房在床边可视化检查、影像学和实验室结果非常有价值，并且这种形式优于传统大查房。
混合现实国际大查房的几乎所有参与者都认为沉浸式 XR 体验——允许在患者床边可视化临床发现、影像学和实验室结果——优于传统大查房形式，并且它可能是一种用于手术教学和远程查房的有价值的工具。
