Summary
Interactive video-based instruction (IVBI) is as effective as traditional teaching for surgical skills. This self-directed learning method is highly rated by House Surgeons and can reduce instructor needs in low-resource settings.
Area of Science:
- Medical Education
- Surgical Training
- Health Professions Education
Background:
- Acquiring basic surgical skills is crucial for House Surgeons.
- Traditional instructor-led teaching methods require significant personnel resources.
- Exploring innovative, effective, and scalable teaching modalities is essential.
Purpose of the Study:
- To compare the efficacy of self-directed interactive video-based instruction (IVBI) against instructor-led teaching for basic surgical skills acquisition.
- To assess House Surgeons' satisfaction with self-directed IVBI.
Main Methods:
- A prospective, 1:1 randomized controlled trial was conducted with 50 House Surgeons.
- Participants were assigned to either self-directed IVBI or instructor-led teaching groups.
- Surgical skills (knot tying, suturing) were assessed using the Objective Structured Assessment of Technical Skills (OSATS) pre- and post-intervention.
Main Results:
- Both IVBI and instructor-led teaching significantly improved OSATS scores (p < 0.001).
- Self-directed IVBI was noninferior to instructor-led teaching, with a mean posttest OSATS score difference within the noninferiority margin.
- Over 90% of students using IVBI expressed high satisfaction and supported its integration into the curriculum.
Conclusions:
- Self-directed IVBI is a noninferior method for teaching surgical skills compared to traditional instruction.
- IVBI offers a highly satisfactory learning experience for House Surgeons.
- Self-directed IVBI presents a scalable solution to reduce personnel demands and enhance surgical skills training, particularly in resource-limited environments.
