Improving bowel preparation for colonoscopy in people with IBD

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Patients scheduled for colonoscopy at participating hospitals will be approached before the procedure or within seven days after their colonoscopy to give informed consent and complete a detailed questionnaire. The questionnaire records patient factors (eg, BMI, surgery history, diabetes, bowel habits) and specifics of the bowel-preparation protocol (diet, cleansing agent, dose, timing, and interval before colonoscopy). Clinicians will record Boston Bowel Preparation Scale scores for each segment and collect colonoscopy diagnoses and endoscopic activity scores. Data will be used to describe current protocol implementation since the 2023 guidelines, identify risk factors for poor preparation, and develop a prediction model to guide personalized regimens.
