Simulation-based training (SBT) before conventional clinical training significantly reduces the number of esophagogastroduodenoscopy (EGD) procedures needed for competency. This approach enhances trainee skill acquisition without impacting patient satisfaction or training costs.
Area of Science:
- Medical Education
- Gastroenterology
- Surgical Simulation
Background:
- The quality of esophagogastroduodenoscopy (EGD) is influenced by trainee competency and training methods.
- Optimizing training pathways is crucial for developing proficient endoscopists.
Purpose of the Study:
- To evaluate if simulation-based training (SBT) followed by conventional clinical training (CBT) reduces the number of supervised procedures required for independent EGD performance compared to CBT alone.
Main Methods:
- A randomized controlled trial allocated EGD novices to either SBT + CBT or CBT alone.
- The primary outcome was the number of EGD procedures to achieve independent procedural completion.
- Secondary outcomes included patient satisfaction and training costs.
Main Results:
- The SBT group required significantly fewer procedures (median 31) for independent completion than the CBT-only group (median 44; P = 0.006).
- No significant differences were observed in patient satisfaction between the groups.
- Median training costs were comparable across both groups.
Conclusions:
- Simulation-based training prior to clinical practice accelerates the learning curve for EGD.
- SBT integration is effective in improving trainee efficiency without compromising patient care or increasing costs.
- These findings support the routine adoption of SBT for EGD training.
