As a consequence of the continued Covid-19 lockdown in Germany, in-hospital teaching for medical students was impossible. While lectures and other theoretical training were relatively easily converted into online sessions using platforms such as Moodle, Zoom and Microsoft Teams, this was not the case for practical skills and clinical interventions, such as bronchoscopy or colonoscopy. This study describes a workaround that was implemented at the Saarland University Hospital utilizing virtual reality equipment to convey the impressions of shadowing clinical procedures to the students without physical presence. To achieve this, 3D 180° videos of key clinical interventions of various internal medicine specialities were recorded, cut, and censored. The videos were uploaded to the e-learning YouTube channel of our institution and shared with the students via the private share function. The students could choose whether to use a VR-viewer to watch the videos immersively or to watch them without a viewer on a screen non-immersively. At the end of the course after 1 week, the students completed a questionnaire anonymously focusing on learning-success regarding the presented topics, a self-assessment, and an evaluation of the course. A total of 27 students watched the videos with a VR-Viewer and 74 watched non-immersively. Although the VR-viewer group self-assessed their expertise higher, there was no significant difference between the two groups in the learning-success test score. However, students in the VR-viewer group rated the learning atmosphere, comprehensibility, and overall recommendation of the course significantly higher. They also agreed significantly more to the statement, that they gained a better conception of the presented procedures, and that virtual reality might be an appropriate tool for online teaching. Video-assisted teaching facilitates learning and might be a valuable add-on to conventional teaching.

由于德国持续的新冠疫情封锁,医学生的医院内教学成为不可能。虽然讲座和其他理论培训可以相对容易地通过 Moodle、Zoom 和 Microsoft Teams 等平台转换为在线课程,但实践技能和临床干预则不然,例如支气管镜检查或结肠镜检查。本研究描述了一种在萨尔兰大学医院实施的解决方法,该方法利用虚拟现实设备向学生传达临床操作的印象,而无需学生实际在场。为此,记录、剪辑和审查了各种内科专业关键临床干预的 3D 180°视频。这些视频被上传到我们机构的电子学习 YouTube 频道,并通过私人共享功能与学生共享。学生可以选择使用 VR 观看器沉浸式观看视频,或在没有观看器的情况下非沉浸式观看视频。在课程结束后一周,学生匿名完成了一份关于所呈现主题的学习成功、自我评估和课程评估的问卷。共有 27 名学生使用 VR 观看器观看视频,74 名学生非沉浸式观看视频。尽管 VR 观看器组自我评估的专业技能更高,但两组在学习成功测试得分上没有显著差异。然而,VR 观看器组对学习氛围、理解度和课程整体推荐的评价明显更高。他们也更同意这样的说法,即他们对所呈现的程序有了更好的理解,虚拟现实可能是在线教学的一种合适工具。视频辅助教学有助于学习,可能是传统教学的有益补充。Covid-19:严重急性呼吸综合征冠状病毒 2;3D:三维;2D:二维;VR:虚拟现实。
