What this trial studies
Inoutpatients undergoing colonoscopy, this randomized study compares three education methods to see which yields the best bowel cleansing as measured by the BBPS. Participants are assigned to usual verbal counseling, a tri-lingual pamphlet with brief explanation, or QR-linked instructional videos with brief explanation. Endoscopists and staff are blinded to assignment, and the primary analysis is based on ITT comparison of adequate vs inadequate bowel preparation. The study is conducted at Hospital Sibu Endoscopy Unit in Sarawak, Malaysia, with 324 participants planned (108 per arm).
Why it matters
Potential benefit: If effective, the preferred education modality could improve colonoscopy prep quality, potentially reducing cancellations and repeat procedures.
How similar studies have gone: Prior work suggests education modality can influence bowel preparation quality, but direct comparisons among verbal, written, and video formats in this setting are limited.
