Colonoscopy education delivered via the patient portal does not improve adherence to scheduled first-time screening...

Background and study aims  Non-adherence to scheduled colonoscopy burdens endoscopic practices and innovative approaches to improve adherence are needed. We aimed to assess the effect of an educational video emphasizing colonoscopy importance delivered through the electronic health record patient portal upon "no-show" and late cancellation rates (non-adherence) in patients scheduled for first-time screening colonoscopy. Patients and methods  We conducted a single center randomized controlled trial among patients scheduled for their first screening colonoscopy. Patients were randomized to routine care ("control") or video education ("video"). Control patients received a portal message 14 days prior to colonoscopy date; video patients additionally received a link to the educational video. Results  In total, 830 patients (59 % female, median age 55 years) were randomized ("control": 406; "video": 424). Nearly all (88 %) opened the message; in the video arm, most (72 %) watched a majority of the video. Overall, 80 % attended their scheduled colonoscopy appointment (late cancel: 18 %, "no show": 1 %) and 90 % underwent colonoscopy within 3 months of appointment. Adherence rates did not differ between video and control arms for the scheduled appointment (OR 1.2, CI 0.9-1.8) or for colonoscopy within 3 months of scheduled appointment (OR 1.3, CI 0.8-2.1). Bowel preparation quality did not differ between the groups. Conclusion  Most patients scheduled for colonoscopy will open a patient portal message and, when delivered, watch an educational video. However, delivery of an educational video two weeks prior to screening colonoscopy appointment did not improve adherence.
