Adams MA, Rubenstein JH, Holleman R, Lipson R, Klamerus ML, Zoulek S, Saini SD. Rising use of surveillance colonoscopy and potential impacts. The American journal of managed care. 2022 May 1; 28(5):229-231.
OBJECTIVES: To quantify temporal changes in colonoscopy indication and assess appropriateness of surveillance use in older adults. STUDY DESIGN: Retrospective longitudinal study of national Veterans Health Administration (VHA) data of all patients who underwent outpatient colonoscopy in 2005-2014. METHODS: After validating an electronic algorithm for classifying colonoscopy indication in VHA, we examined trends in colonoscopy indication over time and across patient characteristics. RESULTS: The 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. CONCLUSIONS: Guidelines 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.
