ObjectivesTo quantify temporal changes in colonoscopy indication and assess appropriateness of surveillance use in older adults.Study DesignRetrospective longitudinal study of national Veterans Health Administration (VHA) data of all patients who underwent outpatient colonoscopy in 2005-2014.MethodsAfter validating an electronic algorithm for classifying colonoscopy indication in VHA, we examined trends in colonoscopy indication over time and across patient characteristics.ResultsThe proportion of colonoscopies performed for postpolypectomy surveillance increased significantly during the study period, particularly among older patients with limited life expectancy, raising concern for possible overuse.ConclusionsGuidelines should make clear recommendations about when and how to discontinue postpolypectomy surveillance colonoscopy. Doing so would potentially reduce harms due to complications from low-value procedures and in turn moderate demand and thereby enhance overall procedural access for patients more likely to benefit.
