Abstract
Objectives: Focused ultrasound (US) is being incorporated across all levels of medical education. While many comprehensive US courses exist, their scope is broad, requiring expert instructors, access to simulation, and extensive time commitment by the learner. We aim to compare learning across levels of training and specialties using a goal-directed, web-based course without live skills training.
Design: A prospective observational study of students and residents from medicine, surgery, and anesthesiology. Analysis compared pre- and post-tests assessing 3 competencies. Individual mean score improvement (MSI) was compared by paired-sample t-tests and MSI between cohorts by ANOVA (Analysis of Variance), with significance set at p≤0.05. McNemar’s test compared those who agreed or strongly agreed with survey items to those who did not before and after intervention.
Setting: The research study was set up at the Jackson Memorial Hospital, Miami. Florida, residency training programs in Medicine, Surgery, and Anesthesiology.
Results: 180 trainees participated. A significant MSI was noted in each of the three competencies in all three cohorts. Students’ (S) MSI was significantly higher than residents’ (R) & interns’ (I) in US “knobology” and window recognition [S=2.28±1.29/5 vs R=1.63±1.21/5 (p=0.014); vs I=1.59±1.12/5 (p=0.032)]; students’ total score MSI was significantly higher than residents [7.60±3.43/20 vs 5.78±3.08/20 (p<0.008)]. All cohorts reported improved comfort in using transthoracic US and improved ability to recognize indications for use. More than 81% of all participants reported improved confidence in performing transthoracic US; more than 91% reported interest in additional training; more than 88% believed course length was appropriate.
Conclusions: Learners across levels of medical training and specialties can benefit from a brief, goal-directed, web-based training with early incorporation producing maximal yield.
