In this report, we present a cardiac ultrasound training module for medical student learners. The module assists medical students in developing foundational skills in image acquisition, identification of normal cardiac ultrasound anatomy, and demonstration of professionalism when performing the associated OSCE exam.
We delivered the module across a 2-week cardiology rotation. On the first day, participants completed a pretest, a 1-hour introductory tutorial including a drawing exercise, and 1-hour of supervised practice with ward patients. Following supervised practice, participants were provided with an ultrasound machine for self-directed practice over the remainder of the clinical rotation. On the final day, participants completed a posttest and module evaluation. Pre- and posttest OSCE scores were compared to assess participants' cardiac ultrasound skills.
A total of 121 students completed the module, of whom 116 completed the pre- and posttest. Median OSCE scores improved from 6 to 24 out of 39 ( < .001). Before the module, 9% of participants or they were able to identify cardiac anatomy on an ultrasound of the heart, which increased to 98% after the module. Following the module, 92% of participants or that ultrasound training helped with other learning on the cardiology rotation.
We demonstrated that a brief training session followed by self-directed ward-based practice improved cardiac ultrasound skills in undergraduate medical students. Participants felt more confident identifying cardiac anatomy, and a large proportion felt the ultrasound training helped with other learning objectives on the cardiology rotation.
在本报告中，我们介绍了一个针对医学专业学生的心脏超声培训模块。该模块帮助医学生培养图像采集的基础技能、识别正常心脏超声解剖结构，以及在进行相关客观结构化临床考试（OSCE）时展现专业素养。
我们在为期两周的心脏病学轮转期间开展该模块培训。第一天，参与者完成了一项预测试、一个包括绘图练习的1小时入门教程，以及1小时在病房对患者进行的带教实践。带教实践结束后，为参与者提供一台超声机器，以便他们在临床轮转的剩余时间进行自主练习。在最后一天，参与者完成了一项后测试和模块评估。比较预测试和后测试的OSCE分数，以评估参与者的心脏超声技能。
共有121名学生完成了该模块培训，其中116名完成了预测试和后测试。OSCE分数中位数从39分中的6分提高到了24分（P<0.001）。在该模块培训前，9%的参与者（或更少）能够在心脏超声检查中识别心脏解剖结构，而在培训后这一比例增至98%。完成该模块培训后，92%的参与者（或更多）表示超声培训有助于心脏病学轮转中的其他学习。
我们证明，经过简短的培训课程并随后进行基于病房的自主练习，可提高本科医学生的心脏超声技能。参与者在识别心脏解剖结构时更有信心，并且很大一部分人认为超声培训有助于实现心脏病学轮转中的其他学习目标。
