Abstract

Background: Electrodiagnostic (EDX) studies are critical for surgical decision-making in nerve injuries. Surgeons typically rely on the electrodiagnostician’s reports and lack formal training in EDX interpretation. This knowledge gap highlights a need for accessible and effective educational resources for surgeons to improve their understanding of EDX and enhance patient care. Methods: The educational module consisted of a pre-lecture knowledge assessment, a 42-minute video lecture on interpreting electrodiagnostic studies, and a post-lecture knowledge assessment. Knowledge retention was assessed via an additional survey distributed three months after module completion. Results: This study, involving 119 participants (79% attending surgeons, 8% fellows, 9% surgical residents, and 2% who described their position as “other”), demonstrated that a 42-minute video-based learning module significantly improved knowledge of EDX interpretation. Median scores increased from 7 to 9 (p<0.001), with improvement persisting at three months (median retention score of 11, p<0.025). Notably, among surgeons completing the three-month assessment, 65.5% reported that knowledge gained from the module had changed their clinical practice. Conclusion: This study demonstrates that a concise, video-based learning module can effectively enhance surgeon knowledge of EDX interpretation and may serve as a valuable tool for surgical education and improving patient selection in nerve surgery.
