Video-Based Versus Bedside eFAST Training in Final-Year Medical Students

25 agosto 2026 aggiornato da: Gorkem Alper Solakoglu

Comparative Effectiveness of Video-Based and Bedside Teaching for eFAST Training in Final-Year Medical Students: A Randomised Controlled Educational Trial

This study compared two methods of teaching the Extended Focused Assessment with Sonography for Trauma (eFAST) examination to final-year medical students. Participants were randomly assigned in a 1:1 ratio to either a 60-minute standardized video-based training session or a 60-minute instructor-led bedside training session. Both groups received the same educational content, for the same duration, from the same instructor.

Within one hour after completing the training, each participant performed an individual eFAST examination on a healthy volunteer. Performance was assessed by an evaluator who was unaware of the participant's training group, using an eFAST Image Acquisition Checklist. The study compared overall immediate eFAST performance between the two teaching methods and also examined performance in individual eFAST examination windows.

Descrizione dettagliata

This was a single-center, parallel-group, individually randomized educational trial involving final-year medical students undertaking an emergency medicine clerkship. Participants with previous formal ultrasound training or prior practical ultrasound experience were excluded. One hundred consenting participants were randomized, with 50 assigned to standardized video-based eFAST training and 50 assigned to instructor-led bedside eFAST training.

Both interventions lasted 60 minutes and covered the same theoretical and practical eFAST content. Participants underwent an individual practical assessment on a healthy volunteer within one hour after training. Outcome assessors were blinded to training allocation. Performance was assessed using an eFAST Image Acquisition Checklist, which generated an overall score ranging from 0 to 100 and window-specific classifications of error-free performance.

No primary outcome was designated in advance of the analysis. For the present report and retrospective trial registration, the overall eFAST performance score is designated as the primary outcome, while the window-level comparisons are considered exploratory secondary outcomes.

Sperimentale: Video-Based eFAST Training
Participants received a 60-minute standardized video-based eFAST training session. The video was recorded on a healthy volunteer and covered the theoretical principles and practical performance of eFAST, including clinical indications, ultrasound physics, examination windows, transducer selection, probe positioning and orientation, image optimization, normal anatomical landmarks, and representative pathological images.
Participants watched a standardized 60-minute instructional video covering the theoretical principles and practical performance of eFAST.

Content included the principles and clinical indications of eFAST, ultrasound physics, examination windows, transducer selection, probe positioning and orientation, image optimization, normal anatomical landmarks, and representative pathological images.
Comparatore attivo: Instructor-Led Bedside eFAST Training
Participants received a 60-minute instructor-led bedside eFAST training session on a healthy volunteer. The session covered the same theoretical and practical content as the video-based intervention and included live demonstration of each eFAST examination window followed by supervised practice, during which each participant performed the examination once under direct guidance.

Misura Descrizione
Lasso di tempo
Overall eFAST Performance Score
Lasso di tempo: Within 1 hour after completion of the assigned training session
Overall practical eFAST performance was assessed using the eFAST Image Acquisition and Interpretation Assessment Checklist. The checklist comprised 21 image-acquisition items across six eFAST windows and one image-differentiation component. Image-acquisition items contributed a maximum of 84 points and image differentiation contributed a maximum of 16 points, yielding a total score from 0 to 100, with higher scores indicating better performance. For this retrospective registration, the overall performance score is designated as the primary outcome; no primary outcome was prospectively designated before the analysis.
Within 1 hour after completion of the assigned training session
