Optimizing Timing of Follow-Up Colonoscopy: A Pilot Cluster Randomized Trial of a Knowledge Translation Tool.

Background: Endoscopists have low adherence to guideline-recommended colonoscopy surveillance intervals. We performed a cluster-randomized single-blind pilot trial in Winnipeg, Canada, to assess the effectiveness of a newly developed digital application tool that computes guideline-recommended follow-up intervals.

Methods: Participant endoscopists were randomized to either receive access to the digital application (intervention group) or not receive access (control group).

Mandatory vs. optional split-dose bowel preparation for morning colonoscopies: a pragmatic noninferiority randomized controlled trial.

BACKGROUND : We compared the effectiveness of optional split-dose bowel preparation (SDBP) with mandatory SDBP for morning colonoscopies in usual clinical practice. METHODS : Adult patients undergoing outpatient early morning (8:00 AM-10:30 PM) and late morning (10:30 AM-12:00 PM) colonoscopies were included. Written bowel preparation instructions were provided based on randomization: one group were instructed to take their bowel preparation (4 L polyethylene glycol solution) as a split dose (mandatory), while the comparator group was allowed the choice of SDBP or single-dose bowel preparation administered entirely on the day before (optional).
