Evaluation of a High-risk Patient Reminder System for Colonoscopy Surveillance.

In this paper we report the evaluation of a proprietary recall system for promoting compliance with recommended follow-up in high-risk patients. We conducted a retrospective chart review for patients of an active private colon and rectal surgery practice having colonoscopy in 2006. Patients selected were <80 years of age and assessed to be high-risk by findings at exam or personal/family history of colorectal neoplasm with a recommendation for follow-up surveillance colonoscopy ranging from months to 5 years. Up to 6 months from recommendation was considered to be within compliance. A total of 795 patients met the inclusion criteria, with average age of 63.2 years, 422 (53.1%) being men. Compliance with surveillance colonoscopy recommendations was 62.5%. The recall system impacted patient behavior with compliant patients being sent a median of one letter (average, 1.5) and late or no follow-up patients being sent a median of 4 letters (average, 3.9). Multiple contacts with patients are required to improve compliance with surveillance. Our findings support at least 4 to 5 efforts to remind patients of the importance to schedule a colonoscopy is necessary to optimize compliance.
