IntroductionColorectal cancer (CRC) is the second leading cause of cancer mortality in the U.S.; however, if the population aged 50 years or older received routine screening, approximately 60% of these deaths could be eliminated. This study investigates whether adults, aged 50-75 years, with one of three disabilities (blind/low vision [BLV], intellectual disability [ID], spinal cord injury [SCI]) receive CRC screening at rates equivalent to adults without the three disabilities, by accounting for combinations of recommended CRC screenings during a 10-year period (colonoscopy, sigmoidoscopy, fecal occult blood test).MethodsSouth Carolina Medicaid and Medicare, State Health Plan, and hospital discharge data (2000-2009) were analyzed (2013-2015) to estimate the proportion of adherence to and adjusted odds of CRC screening over time among adults with one of the three disabilities, BLV, ID, or SCI, versus adults without these conditions.ResultsThe estimated proportion of adults who adhere to changing recommendations over time was lower for adults with ID (34.32%) or SCI (44.14%) compared with those without these disabilities (48.48%). All three case groups had significantly lower AORs of adherence versus those without (BLV: AOR=0.88, 95% CI=0.80, 0.96; ID: AOR=0.55, 95% CI=0.52, 0.59; SCI: AOR=0.88, 95% CI=0.82, 0.95).ConclusionsIn this study, adults with BLV, ID, or SCI were less likely to receive and adhere to CRC screening recommendations than those without these disabilities. This method provides a thorough evaluation of adherence to CRC screening by considering levels of adherence during each month of Medicaid or Medicare coverage.Copyright © 2017 American Journal of Preventive Medicine.
