Patient-, Provider-, and System-Level Factors in Low Adherence to Surveillance Colonoscopy Guidelines: Implications for Future Interventions

Purpose Patients with a history of advanced adenomas are at increased risk of developing colorectal cancer (CRC), yet rates of adherence to current surveillance colonoscopy guidelines are poor. We determined rates of referral and adherence to 3-year interval surveillance colonoscopy in patients with advanced adenomas and identified modifiable factors as possible intervention targets to improve surveillance referral and adherence in these at-risk patients.
