NCT07790497

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Overall eFAST Performance Score

    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

Secondary Outcomes (5)

  • Error-Free Anterior Lung Window Performance

    Within 1 hour after completion of the assigned training session

  • Error-Free Subxiphoid Window Performance

    Within 1 hour after completion of the assigned training session

    Within 1 hour after completion of the assigned training session

  • Error-Free Left Upper Quadrant Window Performance

    Within 1 hour after completion of the assigned training session

  • Error-Free Pelvic Window Performance

    ithin 1 hour after completion of the assigned training session

Study Arms (2)

Video-Based eFAST Training

EXPERIMENTAL

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.

Other: Standardized Video-Based eFAST Training

Instructor-Led Bedside eFAST Training

ACTIVE COMPARATOR

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.

Other: Instructor-Led Bedside eFAST Training

Interventions

Participants watched a standardized 60-minute instructional video covering the theoretical principles and practical performance of eFAST. The video was recorded on a healthy volunteer and included demonstrations of the examination with visual annotation. 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.

Video-Based eFAST Training

Participants received a 60-minute instructor-led bedside training session delivered by the same emergency physician on a healthy volunteer. The session covered the same theoretical and practical eFAST content as the video-based intervention and included live demonstration of each examination window followed by supervised practice, during which each participant performed the examination once under direct guidance.
