Nephrologist-Led Simulation-Based Focused Cardiac Ultrasound Workshop for Medical Students: Insights and Implications

Abstract

BackgroundPoint-of-care ultrasonography (POCUS) is being increasingly recognized as an adjunct to physical examination. However, limited availability of trained faculty in specialties other than emergency medicine and lack of universal training standards remain key barriers to its widespread integration into undergraduate and graduate medical curricula. In this study, we sought to explore the effectiveness of a short simulation-based workshop for medical students teaching basic cardiac ultrasound led by a nephrologist. MethodsWorkshops were conducted for 2 different groups of 4th-year medical students with a total of 25 attendees. The workshop consisted of a 1-hour lecture followed by 15 minutes of cardiac anatomy simulation and a 2- to 2.5-hour hands-on session in the simulation laboratory. An anonymous precourse questionnaire comprising 10 questions assessing the interpretation of common grayscale ultrasound findings encountered in patients with undifferentiated hypotension was performed. After the workshop, a postcourse exam and survey were conducted, retesting the same concepts and seeking the students’ feedback on the course. ResultsIn total, 23 and 20 students answered the pre- and postcourse surveys, respectively. The mean total score on the pretest was 63.8% ± 13.6%, which significantly increased to 91.5% ± 10.5% on the posttest (P < .001). About 90% of the respondents strongly agreed that the cardiac anatomy simulation improved their understanding of the cardiac sonographic anatomy; 75% strongly agreed that the hands-on simulation enhanced their confidence in image acquisition and interpretation; and 70% said they would choose nephrology elective if POCUS training was integrated with it. ConclusionsA nephrologist-led diagnostic POCUS workshop using simulation techniques is effective in improving the learners’ knowledge, understanding of the sonographic cardiac anatomy, and confidence in image acquisition. Integration of POCUS training may increase medical student interest in nephrology elective rotations.
