Many medical specialties have adopted the use of ultrasound, creating demands for higher-quality ultrasound training at all levels of medical education. Little is known about the long-term benefit of integrating ultrasound training during undergraduate medical education. This study evaluated the effect of a longitudinal fourth-year undergraduate medical education elective in ultrasound and its impact on the future use of ultrasound in clinical practice.
A cross-sectional survey of medical graduates from The Ohio State University College of Medicine (2006-2011) was done, comparing those who participated and those who did not participate in a rigorous ultrasound program for fourth-year medical students. A 38-item questionnaire queried graduates concerning ultrasound education in residency, their proficiency, and their current use of ultrasound in clinical practice.
Surveys were completed by 116 respondents, for a return rate of 40.8% (116 of 284). The participants of the undergraduate medical education ultrasound elective (n = 61) reported more hours of ultrasound training after graduation (hands-on training, bedside scanning, and number of scans performed; P < .001), higher ultrasound proficiency (proficiency in using ultrasound for clinical decision making, use in emergency settings, and use of novel techniques; P< .001), and higher rates of ultrasound use in clinical practice (P < .001).
The longitudinal undergraduate medical education ultrasound elective produced physicians who were more likely to seek additional training in residency, evaluate themselves as more proficient, and use ultrasound in their clinical practice. Early training in bedside ultrasound during undergraduate medical education yields physicians who are better prepared for integration of ultrasound into clinical practice.
许多医学专业都开始使用超声，这对医学教育各阶段的高质量超声培训提出了需求。关于在本科医学教育中整合超声培训的长期益处，人们了解甚少。本研究评估了本科四年级医学教育中为期一年的超声选修课程的效果及其对超声在临床实践中未来使用情况的影响。
对俄亥俄州立大学医学院2006 - 2011年的医学毕业生进行了横断面调查，比较参与和未参与针对四年级医学生的严格超声课程的毕业生。一份包含38个条目的问卷询问了毕业生关于住院医师培训期间的超声教育、他们的熟练程度以及他们目前在临床实践中使用超声的情况。
116名受访者完成了调查，回复率为40.8%（284人中的116人）。本科医学教育超声选修课的参与者（n = 61）报告称毕业后有更多小时的超声培训（实践操作培训、床边扫描以及执行的扫描次数；P < .001）、更高的超声熟练程度（在临床决策中使用超声的熟练程度、在紧急情况下的使用以及新技术的使用；P < .001）以及在临床实践中更高的超声使用率（P < .001）。
本科医学教育中的纵向超声选修课培养出的医生更有可能在住院医师培训中寻求额外培训，自我评估为更熟练，并在临床实践中使用超声。本科医学教育期间早期的床边超声培训培养出的医生在将超声整合到临床实践方面准备更充分。
