Assessment of EFAST training for final year medical students in emergency medicine clerkship

Background: Extended Focused Assessment Sonography for Trauma (EFAST) is an important bedside tool for the management of multiple trauma patients. We aimed to evaluate the assessment of our EFAST education in the Emergency Medicine Clerkship (EMC) for final year medical students and the correlations of EFAST marks with other practical skill stations and the final multiple choice question (MCQ) exam marks. Methods: Fifty-four final year medical students were trained on performing EFAST on human models during their 4-week clerkship. Students received an hour of didactic lecture, 4-hours practical sessions on human models, and completed a minimum of three EFAST examinations on trauma patients. Finally, the EFAST performance was evaluated on human models using a standard evaluation form during an Objective Structured Clinical Examination (OSCE). The marks of 51 students who completed the final exam were analyzed. Results: The overall passing rate of the EFAST station was 88% (n: 45). EFAST station mark had significant weak correlations with other OSCE stations marks (p = 0.027, rho = 0.31), and with the final EMC mark (p = 0.032, rho = 0.3), but not with the final MCQ exam. Conclusions: Final year medical students demonstrated effective EFAST learning as measured by their examination performance. One hour EFAST training and 4 -hours practice provide an acceptable level of skill for medical students. The EFAST final marks showed significant weak correlation with other OSCE station marks and final clerkship marks, but not with the final MCQ exam mark which assesses a different cognitive learning domain.
