Effectiveness of a 1-Hour Extended Focused Assessment With Sonography in Trauma Session in the Medical Student Surgery Clerkship.

OBJECTIVE: To demonstrate the effectiveness of incorporating 1 hour of ultrasound training on the extended focused assessment with sonography in trauma (eFAST) into the year-3 medical student surgical clerkship.

DESIGN: A prospective cohort study where participants served as self-controls. One hour of instruction in the eFAST examination, along with 3 required observed examinations, was incorporated into the year-3 surgery clerkship. Effectiveness of the training was evaluated by a preliminary and posttraining assessment. An online survey was used assessing comfort based on a 5-point Likert scale. An online quiz was used assessing knowledge, and a 2-part objective structured clinical examination (OSCE) was used assessing skill and speed. Participants also logged 3 eFAST examinations during the 10-week clerkship where they reported their comfort in performing and interpreting the eFAST on a 5-point Likert scale. Postassessment was held during the last week of the clerkship and included the same online quiz, survey, and 2-part OSCE.

SETTING: The study was performed at Loma Linda University and affiliated hospitals where surgical clerkship students rotate.

PARTICIPANTS: A total of 148 year-3 medical students completed the study.

RESULTS: All testing modalities showed improvement. The mean average of the OSCE improved from 46% ± 27% to 81% ± 18%. The percentage of participants able to perform the examination in less than 6 minutes increased from 18% ± 27% to 84% ± 36%. Participants' comfort level in recognizing eFAST pathology increased from a mean of 2.40 ± 0.94 to 3.55 ± 0.87 out of 5. Comfort in performing the eFAST examination improved from 2.81 ± 0.79 to 3.77 ± 0.68. Comfort in interpreting the eFAST examination improved from 2.88 ± 0.87 to 3.65 ± 0.72.

CONCLUSIONS: This study demonstrates that incorporating 1 hour of eFAST training into the general surgery clerkship is feasible and may lead to improved competency in performing and interpreting the eFAST examination.
