Medical education has been transformed during the COVID-19 pandemic, creating challenges regarding adequate training in ultrasound (US). Due to the discontinuation of traditional classroom teaching, the need to expand digital learning opportunities is undeniable. The aim of our study is to develop a tele-guided US course for undergraduate medical students and test the feasibility and efficacy of this digital US teaching method.
A tele-guided US course was established for medical students. Students underwent seven US organ modules. Each module took place in a flipped classroom concept via the Amboss platform, providing supplementary e-learning material that was optional and included information on each of the US modules. An objective structured assessment of US skills (OSAUS) was implemented as the final exam. US images of the course and exam were rated by the Brightness Mode Quality Ultrasound Imaging Examination Technique (B-QUIET). Achieved points in image rating were compared to the OSAUS exam.
A total of 15 medical students were enrolled. Students achieved an average score of 154.5 (SD ± 11.72) out of 175 points (88.29 %) in OSAUS, which corresponded to the image rating using B-QUIET. Interrater analysis of US images showed a favorable agreement with an ICC (2.1) of 0.895 (95 % confidence interval 0.858 < ICC < 0.924).
US training via teleguidance should be considered in medical education. Our pilot study demonstrates the feasibility of a concept that can be used in the future to improve US training of medical students even during a pandemic.
在 COVID-19 大流行期间，医学教育发生了转变，这对超声（US）的充分培训带来了挑战。由于传统课堂教学的中断，扩大数字学习机会的需求是不可否认的。我们的研究旨在为医学生开发一门远程指导 US 课程，并测试这种数字 US 教学方法的可行性和效果。
为医学生建立了远程指导 US 课程。学生接受了七个 US 器官模块的培训。每个模块都通过 Amboss 平台以翻转课堂的形式进行，提供了可选的补充电子学习材料，其中包括每个 US 模块的信息。采用客观结构化的 US 技能评估（OSAUS）作为期末考试。课程和考试的 US 图像由亮度模式质量超声成像检查技术（B-QUIET）进行评分。将图像评分的得分与 OSAUS 考试进行比较。
共有 15 名医学生参加了课程。学生在 OSAUS 中平均得分为 154.5（标准差 ± 11.72），得分为 175 分（88.29%），这与 B-QUIET 的图像评分相对应。US 图像的组内评分分析显示出良好的一致性，ICC（2.1）为 0.895（95%置信区间 0.858<ICC<0.924）。
应考虑在医学教育中采用远程指导的 US 培训。我们的初步研究证明了这一概念的可行性，该概念可用于未来在大流行期间甚至提高医学生的 US 培训。
