Ultrasound education has been provided to students in medical schools within and beyond the United States. A formal experiment with use of personal handheld ultrasound equipment by all first-year medical students has not been reported. Employing insonation (an application of ultrasound) at the personal leisure by medical school freshmen enables self-directed learning throughout the academic year.
We describe a peer-led ultrasound curriculum with handheld devices. The students' perceptions were gathered through quarterly Likert-style questionnaires, and the differences in the categories were tested using Analysis of Variance.
The response rate was 58.5% for the first survey (n = 32), 56% (n = 30) for the second survey, and 62.3% (n = 33) for the final survey, respectively, with an average response rate of 58.9%. At the baseline survey, overall agreement was observed for enhancement on performance (62.5%) and interpretation (56.3) of ultrasounds, understanding (68.8%) and learning of anatomy (61.3%), ease (78.1%), comfort (59.4%) and benefit of incorporation of insonation in the medical school curricula (all p-values < 0.001). Neutral response (38.7%) or disagreement (38.7%) was observed when assessing the effect of the integration in medical curriculum on specialty choice (p < 0.01). These trends remained constant over follow-up with the exception that the perceived benefit for integration of insonation into the longitudinal curricula (p < 0.05) increased significantly over time. Majority of disagreement was observed regarding current access to the personal ultrasound devices (38.7%) (p < 0.001).
The introduction of insonation through personal handheld ultrasound devices in the first-year medical school curriculum was received enthusiastically by students, with the majority of respondents finding the devices both easy to use and a valuable aid to improving their understanding of the three-dimensional anatomy.
在美国和其他国家的医学院校中，都为学生提供了超声教育。尚未有报道称，所有一年级医学生都使用个人手持式超声设备进行正式的实验。让医学院新生在个人闲暇时间进行超声检查，可以在整个学年中实现自主学习。
我们描述了一种使用手持式设备的同伴指导超声课程。通过季度李克特式问卷收集学生的看法，并使用方差分析测试类别之间的差异。
第一次调查的回复率为 58.5%（n=32），第二次调查为 56%（n=30），最后一次调查为 62.3%（n=33），平均回复率为 58.9%。在基线调查中，学生对超声检查表现（62.5%）和解释（56.3%）、理解（68.8%）和解剖学学习（61.3%）、易用性（78.1%）、舒适度（59.4%）以及将超声检查纳入医学院课程的益处（所有 p 值均<0.001）的总体认同度较高。在评估整合对专业选择的影响时，中性（38.7%）或不认同（38.7%）的回应（p<0.01）。随着时间的推移，这些趋势保持不变，除了整合超声检查到纵向课程中的益处感知（p<0.05）随着时间的推移显著增加。大多数人对当前获得个人超声设备存在分歧（38.7%）（p<0.001）。
在医学院一年级课程中引入个人手持式超声设备，受到学生的热烈欢迎，大多数受访者认为这些设备易于使用，并且是提高他们对三维解剖结构理解的有价值的辅助工具。
