Inclusion Criteria:  For physician participants, there are no age limits/parameters. All physicians performing colonoscopy on adult patients in Winnipeg will be eligible to participate (other than those involved in pilot testing and study investigators). Participating physicians will be informed that the introduced intervention will be an information tool to help improve care for individuals undergoing colonoscopy, and will be asked to consent to review of their patient records. Participating physicians will be informed that no individual-level information will be disclosed at any time and all analysis will be on anonymized data. Twenty physicians will be recruited in the pilot study.  For patient participants:  Patients must be older than 40 years and younger than 70 years old for inclusion in the study data. Adequate bowel preparation defined by Boston Bowel Preparation Scale Score of ≥ 2 in each of segments of the colon (Boston bowel prep scale score recording is mandatory in the Winnipeg city-wide endoscopy reporting system); Colonoscopy completed to the cecum/ileocolonic anastomosis; Colonoscopy performed in the month before randomization of endoscopy physician (to determine baseline adherence) or between 3 to 5 months after randomization (to determine effect of the intervention).  Exclusion Criteria:  Physicians will be excluded if they are away for more than six weeks continuously in the six months after randomization. In this situation, an alternate physician will be recruited and randomized. Thus there is no anticipated loss of follow-up.  Patients will be excluded if any of the following criteria are met:  History of inherited CRC predisposition (Lynch Syndrome, Familial adenomatous polyposis, others); Inflammatory bowel disease; Partially excised polyp or endoscopy physician recommending early colonoscopy to document complete excision; Endoscopy physician documenting a rationale for not repeating colonoscopy in future such as co-morbid conditions.
