A transesophageal echocardiography (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.

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.

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.
