Self-Learning Videos in Focused Transthoracic Echocardiography Training

Abstract

Background

Focused transthoracic echocardiography (FOTE) is crucial for patients' bedside management. However, limited opportunities exist for practical FOTE training, prompting the use of simulation and self-learning videos to overcome this constraint. This study aimed to evaluate the impact of incorporating self-learning videos into a simulation FOTE training course.

Approach

This was a prospective, randomized study involving University of Toronto internal medicine residents, who participated in a 2-h didactic and simulation FOTE training course before being randomized to a control group receiving written learning materials or an intervention group with additional self-directed learning videos.

Evaluation

Twenty-eight participants were randomized, and twenty-one (75%) completed the 1-month follow-up. Participants were assessed using a written test on image acquisition techniques and structure identification, scanning time and image quality on a simulator and self-reported scanning comfort, both pre-intervention and 1-month post-intervention. The groups had no significant difference in the time spent reviewing the material (1.5 vs. 1.4 h, p = 0.76). A significant increase in post-course scores was observed in all evaluations except for the control group's written test (p = 0.07). There were no significant between-group differences across the written test (p = 0.7), image quality (p = 0.6) and comfort level (p = 0.7). Compared to the control group, the intervention group exhibited a greater reduction in the scanning time (38 vs. 72 s, p = 0.02).

Implications

FOTE training effectively increases theoretical knowledge and practical skills in a simulated setting. However, limited video utilization by participants precluded the inference of definitive conclusions on the impact of self-learning videos.
