Transesophageal Echocardiography Training of Emergency Physicians Through an E-Learning System.

Abstract Background Transesophageal echocardiography (TEE) has been shown to be a powerful tool that emergency physicians can use to guide resuscitation efforts during cardiac arrest. Currently, there is no standardized curriculum to teach TEE to emergency physicians. Objective We hypothesized that the use of a pilot training course combining interactive e-learning and hands-on simulation would increase the percentage of students achieving a score of ≥80% on a multiple-choice test of knowledge and increase self-reported comfort using TEE. Methods We designed a 2.5-h TEE course for emergency physicians and medical intensive care unit fellows. Participants took a test of knowledge and a survey of comfort—both online—before, just after, and 4 weeks after taking the course. Survey responses measured participants self-reported comfort with using TEE in clinical practice. A normal binomial approximation was used to calculate the 95% confidence interval. Results Of the 3 tests of knowledge, 15 participants completed all tests. Of the surveys of comfort, 31 participants completed the precourse survey, 32 completed the postcourse survey, and 19 completed the 4-week follow-up survey. The proportion of students scoring ≥80% improved from 40% on the precourse test to 80% on the postcourse test (95% confidence interval 1–79). The proportion of students indicating comfort with using TEE improved from 3% precourse to 53% postcourse (95% confidence interval 28–71). Conclusions A TEE training course resulted in a 50% increase in surveyed participants feeling comfortable using TEE in cardiac arrest and a 40% increase in participants scoring ≥80% on a test of knowledge.
