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

Area of Science:

• Neurosurgery
• Medical Education
• Diagnostic Imaging

Background:

• Electrodiagnostic studies are vital for surgical decisions in nerve injuries.
• Surgeons often lack formal training in interpreting these studies, creating a knowledge gap.
• Effective educational resources are needed to improve surgeon understanding and patient care.

Purpose of the Study:

• To assess the effectiveness of a video-based learning module in enhancing surgeons' knowledge of electrodiagnostic study interpretation.
• To evaluate the retention of this knowledge over time.

Main Methods:

• A 42-minute video lecture on interpreting electrodiagnostic studies was delivered.
• Participants completed pre- and post-lecture knowledge assessments.
• Knowledge retention was assessed via a survey 3 months post-module completion.

Main Results:

• The module significantly improved knowledge interpretation scores (median increase from 7 to 9, P < 0.001).
• Knowledge improvement was sustained at 3 months (median retention score 11, P < 0.025).
• 65.5% of surgeons reported a change in clinical practice due to the module.

Conclusions:

• A concise, video-based module effectively enhances surgeon knowledge of electrodiagnostic study interpretation.
• This educational approach can improve patient selection in nerve surgery.
• The module serves as a valuable tool for surgical education.
