Objectives:
Teaching transesophageal echocardiography (TEE) remains challenging. The authors hypothesized that using online modules with live teaching in an echo training course would be feasible and result in superior knowledge acquisition to live teaching only.
Design:
In this prospective cohort study, the authors implemented a TEE course with online modules and live teaching and compared it to a live-teaching-only version.
Setting:
The online-and-live-teaching version of the course consisted of online modules and live sessions at Beth Israel Deaconess Medical Center (BIDMC), an academic medical center. The live-teaching-only version consisted of live sessions at BIDMC.
Participants:
Course participants included anesthesia trainees at BIDMC.
Interventions:
Trainees taking the online-and-live-teaching version viewed online modules before live review lectures and simulation. Trainees taking the live-teaching-only version viewed live lectures before simulation.
Measurements And Main Results:
Twenty-seven trainees completed the online-and-live-teaching version; six completed the live-teaching-only version. Trainees took a course exam after the first and last live sessions. For the online-and-live-teaching version, average pretest and posttest scores were 62.0%±13.7% and 77.5%±8.1%, respectively; pretest and posttest passing (≥70%) rates were 29.6% and 85.2%, respectively. Compared to the live-teaching-only version, the average pretest score was not significantly different (p=0.17), but the average posttest score was significantly higher (p=0.01). Trainee comfort with, and knowledge of, TEE increased after both versions. Trainees rated the utility of the live lectures and online modules similarly.
Conclusions:
A multimodal TEE curriculum increased trainees' knowledge of TEE concepts and had a positive reception from trainees.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
