AbstractIntroduction All practicing emergency medicine (EM) physicians need to maintain a skillset in emergency ultrasound (US) after their initial training. EM physicians in academic practice may be supervising trainees performing ultrasound applications that they aren't comfortable with. This study investigates the effectiveness of a US refresher course. The hypothesis was that a series of short courses would increase confidence in performing and supervising US applications. Methods Nine basic emergency ultrasound applications were taught over the course of one year by ultrasound fellowship-trained EM faculty in a simulation center at a single academic institution. Each session included 30-minutes of didactics/image review and 30-minutes of hands-on practice on normal volunteers and was followed by an anonymous questionnaire evaluating comfort level performing and supervising the ultrasound application before and after the course using a Likert scale from 1 "not at all confident" to 5 "very confident". Results Thirty-six of 60 EM physicians participated in at least 1 of the 9 sessions (median 3, interquartile range 2-4). Faculty who attended had a median of 10 (interquartile range 7-15) years in practice and 61% work at both academic and community sites. For all sessions combined, confidence in performing US increased from a mean score on the Likert scale of 3.3 to 4.4 (difference 1.1, confidence interval (CI) (0.94, 1.29), p < 0.001) and confidence in supervising trainees increased from a mean of 3.4 to 4.5 (difference 1.1, CI (0.88, 1.23), p < 0.001). The largest increases were seen in musculoskeletal (MSK), nerve, and pelvic applications and the least increase was seen with the session focused on intravenous access, but confidence was increased in all sessions. Physicians in practice ≥10 years increased in confidence in performing and supervising the applications by 1.4 (CI (1.11, 1.60), p < 0.001) and 1.3, (CI (1.01, 1.49), p < 0.001), respectively. Physicians in practice <10 years increased 0.8 (CI (0.57, 1.03), p < 0.001) and 0.8 (CI (0.55, 1.05), p < 0.001), respectively. Conclusion An emergency ultrasound refresher course for EM physicians at a single institution improved self-reported confidence in both performing and supervising trainees in all applications reviewed. Those in practice ≥10 years showed the largest increases.Copyright © 2019, Schwid et al.
