This systematic review and meta-analysis evaluated the effectiveness of biotissue models for psychomotor skill acquisition in abdominal surgery, analyzing 31 studies with 574 learners. The findings revealed that repeated practice with these models significantly reduced operative time by 7.5 minutes and improved OSATS scores by 4.41 points, both with p < 0.0001.
Key findings
- Repeated practice reduced operative time by 7.5 minutes (p < 0.0001).
- OSATS scores improved by 4.41 points with practice (p < 0.0001).
- Experts completed biotissue tasks 50.18 minutes faster than novices (p < 0.0001).
Why it matters
The study highlights the potential of biotissue models in enhancing surgical training, which may lead to improved surgical outcomes and efficiency. Understanding their efficacy can help inform training programs in minimally invasive and robotic surgery.
