Colon cancer screening for Colorado's underserved: a community clinic/academic partnership.

BACKGROUND: Colorectal cancer (CRC) is largely preventable by finding and removing adenomas, but many people have not been screened, especially the uninsured with low income. PURPOSE: To establish a statewide infrastructure to ensure that low-income Coloradans receive colonoscopy for CRC screening and diagnostic evaluation. DESIGN: In 2006, a statewide program to provide free colonoscopy to uninsured Coloradans was developed as a partnership between the University of Colorado Cancer Center and Colorado safety-net clinics. Funded by excise tax revenues, the Colorado Colorectal Screening Program (CCSP) successfully embedded screening into primary care, providing patient navigation support and reimbursement that allowed primary care providers to refer patients for colonoscopy. SETTING/PARTICIPANTS: More than 50 safety-net clinics joined the CCSP to provide colonoscopies to uninsured Coloradans with low income, aged ≥50 years or <50 years at elevated risk, lawfully present and needing CRC screening by American Cancer Society consensus guidelines. MAIN OUTCOME MEASURES: Process and clinical outcomes included people screened, show rates, patient satisfaction, and quality measures, such as adenoma detection rate, bowel cleansing quality, and timeliness of care. Program costs and benefits were estimated. The 2013 analysis was completed using 2006-2012 data on 13,252 of 13,774 people receiving colonoscopy. RESULTS: In 2006-2012, the CCSP screened 13,774 people, with 38% minorities and 39% men. Patient navigators ensured >90% of those referred attended their colonoscopy. Adenomas were removed from 27% of patients and 1% had cancers diagnosed. Total direct medical services cost was $998/person receiving colonoscopy. About 325 fewer future incident CRCs were predicted due to adenoma removal, projecting substantial future cost savings. CONCLUSIONS: The CCSP, a successful community clinic/academic partnership provides cost-effective CRC screening and prevention services to low-income uninsured Coloradans and establishes the infrastructure to support screening low-income Coloradans as Affordable Care Act reforms provide payer coverage for them.
