Evaluation of a novel curriculum on point-of-care ultrasound competency and confidence

Point-of-care ultrasound (POCUS) education is a requirement of graduate medical education in EM. Milestones have been established to assess resident US competency. However, the delivery of POCUS education has not been standardized. This study aims to evaluate the impact of implementing a longitudinal, structured POCUS curriculum during EM residency on trainee competency and confidence.

A prospective study of PGY-3 trainees before and after implementation of a novel POCUS curriculum was performed over an 18-month period at an EM residency training program. Curriculum design included longitudinal POCUS application-based monthly electronic content, bi-monthly residency conference sessions, and hands-on rotations. PGY-3 resident's POCUS knowledge was assessed with a 38-question multiple-choice and image-based exam. Further, PGY-3 residents were surveyed regarding POCUS confidence. Survey results evaluated provider confidence, satisfaction with the novel curriculum, and overall perception of POCUS utility scored on a 1 (low) to 5 (high) scale. Results were evaluated using an unpaired t test for data analysis.

Mean quiz scores of 8 pre-curriculum PGY-3 residents (84%; 95%CI 78.46-89.54) were not significantly different when compared with 13 post-curriculum PGY-3 residents (82%; 95%CI 77.11-86.89) (p = 0.6126). Survey results for pre-curriculum trainees across each section were 4.13 (95%CI 3.91-4.35), 3.68 (95%CI 3.32-4.04), and 4.33 (95%CI 4.06-4.6). Results for post-curriculum trainees trended higher for each section at 4.22 (95%CI 4.04-4.40) (p = 0.4738), 3.84 (95%CI 3.52-4.16) (p = 0.5279), and 4.49 (95%CI 4.21-4.77) (p = 0.4534).

Implementation of a structured, longitudinal POCUS curriculum resulted in a trend towards improved trainee confidence, satisfaction, and perception of POCUS. Future studies are needed to identify the optimal structure for POCUS educational content delivery and competency assessment for EM resident providers.
