The acquisition of ultrasound skills is an essential part of any medical student's education. University access restrictions in the context of the COVID-19 pandemic have highlighted the need for digitization in teaching. However, teaching manual skills in online courses has proven to be challenging, not least in terms of human resources. Therefore, the aim of this study was to set up a hybrid head and neck ultrasound course consisting of a preface of video-based self-study followed by supportive instruction by a tutor in telepresence and to evaluate the quality, effectiveness, and feasibility of this teaching method. Thirty-five students were shown video tutorials on systematic ultrasound of the neck course. Learning outcomes were analyzed using self-assessment questionnaires and external assessment by an experienced ultrasonographer. All participants demonstrated statistically significant learning improvement ( < 0.001) when comparing self-assessment scores before and after training. The mean self-assessment scores increased from 13.8 to 26.6 for the telepresence-guided group, from 16.6 to 27.3 for the web-based group, and from 14.0 to 26.2 for the in-person group. The external observer assessment also showed improvement, with mean scores of 46.7, 48.1, and 46.5, respectively. Overall results did not significantly differ when comparing different instruction modalities. A telepresence-guided video-based ultrasound course is well suited to teaching ultrasound skills similar to in-person courses and allows a more resource-efficient targeting of student needs.
超声技能的掌握是任何医学生教育的重要组成部分。在新冠疫情背景下,大学入学限制凸显了教学数字化的必要性。然而,事实证明,在在线课程中教授手动技能具有挑战性,尤其是在人力资源方面。因此,本研究的目的是建立一个混合式的头颈部超声课程,该课程包括基于视频的自学前言,随后由导师进行远程临场支持指导,并评估这种教学方法的质量、有效性和可行性。向35名学生展示了颈部超声系统课程的视频教程。使用自我评估问卷和由经验丰富的超声检查医师进行的外部评估来分析学习成果。比较训练前后的自我评估分数时,所有参与者均表现出统计学上的显著学习进步(<0.001)。远程临场指导组的自我评估平均分数从13.8提高到26.6,网络组从16.6提高到27.3,面对面组从14.0提高到26.2。外部观察者评估也显示出进步,平均分数分别为46.7、48.1和46.5。比较不同的指导方式时,总体结果没有显著差异。基于远程临场指导的视频超声课程非常适合教授超声技能,类似于面对面课程,并且能够更高效地满足学生需求。
