Summary

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.

Conditions

  • Bowel Preparation for Colonoscopy

Interventions

OTHER

Information-framing guidance

For those with an inadequate bowel preparation risk score ≥ 3.25, negatively-framed materials emphasizing the harms of non-adherence are provided; for those with a score \< 3.25, positively-framed materials emphasizing the benefits of adherence are provided.

OTHER

Standard bowel preparation guidance

Patients receive verbal bowel preparation instruction and printed text-based bowel preparation education materials.

OTHER

Individualized bowel preparation regimen

Patients receive verbal instructions and printed illustrated bowel preparation educational material. Patients with a risk score ≥ 3.25 are instructed to take low-residue diet 3 days before colonoscopy and walk for 30 minutes after each meal, with a target of approximately 6,000 steps per day. After consuming each 500 mL of polyethylene glycol electrolyte solution, and finishing the entire solution, patients are asked to chew one piece of sugar-free gum for 10 minutes. Patients with a score \< 3.25 received the standard bowel preparation regimen.
