An Interactive Video Educational Tool Improves the Quality of Bowel Preparation for Colonoscopy: A Randomized Controlled Trial

The investigators aimed to determine whether an interactive, online educational platform could improve procedure show rates and bowel preparation scores in an outpatient population presenting for routine colonoscopy.

Detailed Description

The investigators performed a prospective, endoscopist-blinded, randomized controlled trial at a hospital-based outpatient endoscopy center. Eligible patients were randomized to two groups. Both groups received verbal and written instructions per standard care, while the intervention group received access to an interactive, on-line video. Primary outcomes were bowel preparation scores graded using the Boston Bowel Prep Score (BBPS), procedure show rates, patient satisfaction, and pre-procedure anxiety. Secondary outcomes included adenoma detection rate, mean bowel prep score per colonic segment, total number of polyps detected, and complication rates.
