This study aims to compare the efficacy of remote versus in-person training strategies to teach ultrasound guided knee arthrocentesis using formalin embalmed cadavers.
30 first-year medical student participants were randomly assigned to remote or in-person training groups. Pre- and post- training surveys were used to evaluate participant's self-confidence in their ability to perform the procedure. Participants were asked to watch a 30-minute training video and then attend a skills training workshop. The workshops consisted of 20 min of hands-on instruction followed by a skills assessment.
Following training, participant self-confidence increased significantly across all survey items in both groups (p = 0.0001). No significant changes in participant self-confidence were detected between the groups. Skills and knowledge-related metrics did not differ significantly between the groups with the exception of the "knowledge of instruments" variable.
Our data suggests that remote ultrasound-guided procedure training, although logistically complex, is a viable alternative to traditional in-person learning techniques even for a notoriously hands on skill like ultrasound guided knee arthrocentesis. Novice first-year medical student operators in the remote-training group were able to significantly increase their confidence and demonstrate competency in a manner statistically indistinguishable from those trained in-person. These results support the pedagogical validity of using remote training to teach ultrasound guided procedures which could have implications in rural and global health initiatives where educational resources are more limited.
本研究旨在比较远程与亲身培训策略在使用福尔马林固定尸体教授超声引导膝关节穿刺术方面的效果。
30 名一年级医学生参与者被随机分配到远程或亲身培训组。在培训前后使用问卷调查评估参与者对自己进行该操作能力的信心。参与者被要求观看 30 分钟的培训视频，然后参加技能培训研讨会。研讨会包括 20 分钟的动手指导，然后进行技能评估。
培训后，两组参与者在所有调查项目中的自我信心均显著增加（p=0.0001）。两组之间的参与者自我信心变化没有显著差异。技能和知识相关指标除了“仪器知识”变量外，两组之间没有显著差异。
我们的数据表明，尽管远程超声引导程序培训在物流上很复杂，但即使对于像超声引导膝关节穿刺术这样的动手技能，也是传统亲身学习技术的可行替代方案。远程培训组的新手一年级医学生操作人员能够显著提高他们的信心，并以在统计学上与亲身培训组相同的方式展示出能力。这些结果支持使用远程培训来教授超声引导程序的教学有效性，这可能对农村和全球健康计划有影响，因为这些计划的教育资源更为有限。
