Computer-based lectures for extended focused assessment with sonography for trauma (EFAST) training are effective for residents without prior experience. However, traditional classroom lectures are more beneficial for those with previous ultrasound education.

Area of Science:

  • Medical Education
  • Emergency Medicine
  • Surgical Training

Background:

  • Extended Focused Assessment with Sonography for Trauma (EFAST) is a core curriculum component for Emergency Medicine and Surgery residents.
  • Computer-based lectures offer a potentially time-efficient alternative to traditional teaching methods.

Purpose of the Study:

  • To evaluate if computer-based lectures for EFAST training are non-inferior to traditional classroom lectures in improving resident test scores.
  • To assess the effectiveness of computer-based versus classroom lectures for residents with and without prior ultrasound training.

Main Methods:

  • First-year Emergency Medicine and Surgery residents were randomized into two groups: traditional classroom lectures or computer-based narrated lectures.
  • All participants completed a pre-test and post-test to measure knowledge improvement.

Main Results:

  • Computer-based lectures were found to be non-inferior to classroom lectures for residents without prior ultrasound training (9% confidence limit vs. 10% non-inferiority range).
  • For residents with prior training, computer-based lectures showed inferiority compared to classroom lectures (24% confidence limit vs. 10% non-inferiority range).
  • Overall mean test score improvement was higher in the classroom group (28.0%) than the computer group (18.4%).

Conclusions:

  • Computer-based lectures are a viable and potentially time-saving alternative for initial EFAST training in residents lacking prior ultrasound experience.
  • Traditional classroom lectures appear more effective for didactic ultrasound training in individuals who already possess some ultrasound knowledge.
