Summary
Interactive surgical simulation software significantly improved procedural knowledge for open inguinal hernia repair among medical students. This educational tool enhanced learning outcomes compared to traditional methods.
Area of Science:
- Surgical Education
- Medical Simulation
- Procedural Knowledge Acquisition
Background:
- A novel open inguinal hernia repair surgical simulation software was developed.
- A randomized controlled trial evaluated its educational impact.
Purpose of the Study:
- To assess the benefit of surgical simulation on developing procedural knowledge for hernia repair.
- To compare interactive simulation with non-interactive simulation, video tutorials, and a control group.
Main Methods:
- Medical students were block randomized into four groups: interactive simulation, non-interactive simulation, video tutorial, and control.
- Objective assessments included a multiple-choice question (MCQ) and a simulated surgical discussion.
Main Results:
- Fifty-six students completed the study with similar baseline MCQ scores across all groups.
- Intervention groups (interactive simulation, non-interactive simulation, video tutorial) showed greater improvements in MCQ scores and final assessment compared to the control group.
Conclusions:
- Interactive surgical simulation provides an objective benefit for teaching medical students anatomical and procedural knowledge for open inguinal hernia repair.
- Simulation-based learning enhances surgical skill acquisition and knowledge retention.
