Abstract:

Context Ultrasonography is becoming more prevalent in clinical practice, but medical schools looking to implement preclinical training are limited by financial and faculty resources. Objective To design a single-instructor model to save faculty resources and to determine whether this model is effective at teaching ultrasonography to preclinical medical students. Methods This single-instructor model included 3 components: (1) flipped classroom, where students watched an online lecture covering examination techniques; (2) in-person scanning sessions, where students scanned each other after the instructor went through lecture content and pathologic images, a video camera to show probe placement and examination technique, and a live feed from an ultrasonography demonstration; and (3) feedback on written examination questions and course evaluations. Results When compared with a traditional ultrasonography curriculum, which requires approximately 600 instruction hours annually, this program required 96 hours. Students reported appreciation of exposure to ultrasonography but expressed desire for smaller group sizes and greater individual instruction. Students performed well on written test questions, with the first-year class answering 88% correctly and the second-year class answering 90.6% correctly. Conclusions Although this educational format was used successfully to teach introductory ultrasonography to preclinical students, feedback suggested that students would prefer more individual instruction. The authors look toward implementing a peer-instructor format, forming smaller laboratory groups, and improving skill assessment.
