Two-week intensive medical student point-of-care ultrasound training impact on long term utilization

Abstract

Background: There is little to no data evaluating long term usage of point of care ultrasound (POCUS) after a training intervention for medical students. The purpose of this study was to examine the impact of an intensive POCUS training program on medical student's usage at 9-months post-program. Methods: This was a prospective cross-sectional study of rising second year medical students who participated in a 2-week summer POCUS training program. Instruction consisted of 8 h of asynchronous online didactic material, 2-4 h of daily hands-on instructor-led and independent scanning, and instruction on how to teach POCUS. Students were assessed pre- and post-program, and again at 9 months post-program to evaluate POCUS usage. Results: A total of 56 students participated in the program over 2 summers; 52 (92.9%) responded to the 9-month post-program survey. At 9 months, 49 (94.2%) of students taught POCUS after the program to peers or faculty. Students reported serving as a POCUS instructor in 283 subsequent teaching sessions accounting for 849 h of POCUS instruction time. Six (11.5%) students were involved in the creation of a POCUS interest group on their regional campus, 7 (13%) created a POCUS curriculum for their student interest group, and 4 (7.7%) created an opt-in co-curricular POCUS program for students at their regional campus. Three (5.8%) students did not serve as educators after the program and only one student reported not using POCUS again after the program. Conclusion: After a 2-week intensive POCUS training program for medical students, the majority of students demonstrated continued involvement in POCUS learning and education at 9-month follow-up including serving as peer instructors and assisting with limitations in financial resources and trained faculty.
