A Video-Based Learning Module Is an Effective Way to Teach the Interpretation of Preoperative Electrodiagnostic...

Electrodiagnostic studies are critical for surgical decision-making in nerve injuries. Surgeons typically rely on the electrodiagnostician's reports and lack formal training in electrodiagnostic study interpretation. This knowledge gap highlights a need for accessible and effective educational resources for surgeons to improve their understanding of electrodiagnostic studies and enhance patient care.

The educational module consisted of a prelecture knowledge assessment, a 42-minute video lecture on interpreting electrodiagnostic study results, and a postlecture knowledge assessment. Knowledge retention was assessed by means of an additional survey distributed 3 months after module completion.

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 electrodiagnostic study interpretation. Median scores increased from 7 to 9 ( P < 0.001), with improvement persisting at 3 months (median retention score, 11; P < 0.025). Among surgeons completing the 3-month assessment, 65.5% reported that knowledge gained from the module had changed their clinical practice.

This study demonstrates that a concise, video-based learning module can effectively enhance surgeon knowledge of electrodiagnostic study interpretation and may serve as a valuable tool for surgical education and improving patient selection in nerve surgery.
