A simulation-based training improved healthcare workers' knowledge and confidence in colonoscopy preparation. This led to a significant increase in adequate bowel preparation quality, exceeding 90% compliance.
Area of Science:
- Gastroenterology
- Medical Education
- Quality Improvement
Background:
- Adequate bowel preparation is crucial for colonoscopy success, with international guidelines recommending at least 90% adequacy.
- A local quality review identified a significant issue, with 25.7% of colonoscopies having inadequate preparation.
Purpose of the Study:
- To implement a simulation-based educational intervention to enhance healthcare workers' (HCWs) knowledge and confidence in colonoscopy preparation.
- To assess the impact of the intervention on the quality of bowel preparation in clinical practice.
Main Methods:
- An interactive educational program involving teaching sessions, simulated patient counseling, and debriefing was delivered to 28 gastroenterology HCWs.
- Participants completed pre- and post-intervention tests for knowledge assessment and self-efficacy questionnaires.
- A post-intervention chart review was conducted to evaluate changes in bowel preparation quality.
Main Results:
- Mean pretest scores improved from 58.6% to 75.7% (p < .05), and self-efficacy scores increased from 71.1% to 92.8% (p < .05).
- Qualitative feedback from participants was highly positive.
- A 12-week post-intervention review showed a significant increase in adequate bowel preparation to 92.8% (p < .05).
Conclusions:
- Simulation-based interventions are effective in improving HCWs' counseling skills and confidence regarding colonoscopy preparation.
- The intervention led to a measurable improvement in the quality of clinical care, evidenced by enhanced bowel preparation quality.
