Individualized Non-pharmacological Intervention for Bowel Preparation

Conditions studied: Bowel Preparation for Colonoscopy

In brief

Colonoscopy is essential for the early detection of colorectal cancer. However, inadequate bowel preparation remains a common challenge, associated with reduced adenoma detection rates, prolonged procedure time, and increased healthcare costs. Current individualized regimens rely largely on higher laxative dosages-an approach with limited clinical utility. Non-pharmacological interventions, including dietary modification, physical activity, and health education, are safe and tend to have better patient adherence. The effectiveness of health education depends largely on message framing. Guided by information-framing theory, we developed an individualized non-pharmacological regimen. This randomized controlled trial aims to evaluate the efficacy of this regimen in improving bowel preparation quality.
