Low-fidelity (LF) colonoscopy simulation models effectively train healthcare professionals, yielding skill acquisition and confidence comparable to high-fidelity (HF) models. These cost-effective LF models are ideal for resource-limited settings in low- and middle-income countries (LMICs).
Area of Science:
- Medical Education
- Gastroenterology
- Surgical Training
Background:
- Colorectal cancer (CRC) presents a growing global health challenge, particularly in low- and middle-income countries (LMICs).
- Enhancing colonoscopy expertise through training is vital to combatting rising CRC incidence and mortality.
- Simulation-based training offers a controlled environment for developing colonoscopy skills.
Purpose of the Study:
- To evaluate the efficacy of low-fidelity (LF) colonoscopy simulation models compared to high-fidelity (HF) models for skill acquisition and confidence.
- To assess the feasibility of using locally developed LF models in resource-constrained environments.
Main Methods:
- A randomized crossover trial involving surgeons, residents, and gastroenterologists in Nigeria.
- Training incorporated a 9-week online lecture series and a 4-day in-person workshop using both HF and LF simulators.
- Performance was measured using the Mayo Colonoscopy Skills Assessment Tool (MCSAT) and Global Assessment of Gastrointestinal Endoscopic Skills (GAGES).
Main Results:
- Both LF and HF simulation groups showed significant improvements in median MCSAT and GAGES scores over time.
- Statistically significant differences favoring simulation training were noted in specific GAGES sub-scores after initial training.
- No significant differences in final exam scores between HF and LF groups indicated skill convergence by the end of the course.
- Participants in both groups reported significant increases in confidence.
Conclusions:
- Low-fidelity colonoscopy simulation models facilitate comparable skill acquisition and confidence enhancement to high-fidelity models.
- LF models represent a cost-effective and viable educational tool for colonoscopy training in LMICs.
- This approach can help expand the colonoscopy workforce to address the global burden of colorectal cancer.
