Bowel Preparation Quality Following Video-Based Intervention and Educational Booklet Versus Standard of Care in an Outpatient Setting: A Single-Center, Endoscopist-Blinded Randomized Controlled Trial
Status: Recruiting

Intervention Type: Behavioral
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
High cancellation rates and suboptimal bowel preparation increase patient discomfort, drive economic waste, and compromise clinical outcomes. Despite guideline emphasis on adequate preparation quality, there is no standard on how or when instructions should be delivered. This study compares three common patient education modalities-usual care verbal counseling, written tri-lingual pamphlet, and visual media via smartphone QR code-to determine which yields the best bowel preparation quality as assessed by the Boston Bowel Preparation Scale (BBPS) in an outpatient endoscopy setting.
