Is this trial a fit for you?

Likely a good fit

Adults 18 years or older scheduled for outpatient colonoscopy who can provide informed consent.

Probably not a fit

Patients who are not adherent to non-pharmacological recommendations or who have conditions that necessitate pharmacological regimens may see no benefit.

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

What this trial studies

Adults scheduled for colonoscopy are randomized to three groups to see if an information-framing and tailored non-pharmacological regimen improves bowel cleanliness compared with standard prep. The study uses a risk score to tailor bowel prep intensity and adds illustrated education; the information framing varies by risk to emphasize harms or benefits of adherence. Endoscopists rate bowel cleanliness with the Boston Bowel Preparation Scale, while participants report adherence and motivation. Outcomes include prep quality, willingness for repeat procedures, and adverse events, with blinded assessment of results.

Why it matters

Potential benefit: If successful, patients may experience better bowel cleanliness, shorter procedures, and potentially fewer complications or repeat procedures.

How similar studies have gone: Previous work suggests education and non-pharmacological strategies can improve adherence, but this specific framed, individualized approach is novel.
