Assessment of a New E-Learning System on Thorax, Trachea, and Lung Ultrasound

Abstract EN

Background.

Lung ultrasound has become an emerging tool in acute and critical care medicine.

Combined theoretical and hands-on training has been required to teach ultrasound diagnostics.

Current computer technology allows for display, explanation, and animation of information in a remote-learning environment.

Objective.

Development and assessment of an e-learning program for lung ultrasound.

Methods.

An interactive online tutorial was created.

A prospective learning success study was conducted with medical students using a multiple-choice test (Trial A).

This e-learning program was used as preparation for a certified course followed by an evaluation of trained doctors (Trial B) by linear analogue scales.

Pretests were compared with postcourse tests and sustainability tests as well as a posttest of a one-day custom classroom training.

Results.

In Trial A, during the learning success study (n=29), the increase of correct answers was 11.7 to 17/20 in the post-test and to 16.6/20 in the sustainability test (relative change 45.1%, P<0.0001).

E-learning almost equalled scores of classroom-based training regarding gain and retention of factual knowledge.

In Trial B, nineteen participating doctors found a 79.5% increase of knowledge (median, 95% CI: 69%; 88%).

Conclusion.

The basics of lung ultrasound can be taught in a highly effective manner using e-learning.
