[High-impact ultrashort simulation-based pulmonary ultrasound training for Family Medicine residents: A prospective...

To evaluate the effectiveness of an ultrashort lung ultrasound training program based on advanced clinical simulation for the acquisition of diagnostic and technical skills among Family and Community Medicine residents.

A prospective quasi-experimental pre-post study without a control group was conducted in 80 residents from the Bahía de Cádiz-La Janda Health District between October and November 2025. The 2-hour intervention included baseline assessment, a 15-minute theoretical session, supervised hands-on training using the U/S Mentor™ simulator, and immediate reassessment. Diagnostic knowledge, self-perceived confidence, technical autonomy, and examination time were analyzed. A remote follow-up assessment was performed 40 days later.

The proportion of residents reporting high confidence (4-5/5) increased from 11.3% to 100.0%, and the proportion achieving a high overall score in the theoretical test (4-5 correct answers) rose from 38.8% to 98.8%. All clinical cases showed significant improvement (P<.001). A total of 70.0% achieved the maximum technical performance score, and mean examination time was 188.4±50.5 s, with no differences across residency years (P=.336). At 40 days, high satisfaction and a strong perceived clinical usefulness of the technique persisted.

An ultrashort advanced clinical simulation-based program rapidly and consistently improves knowledge, confidence, and technical performance in lung ultrasound, and may represent a feasible educational strategy for postgraduate training.
