Abstract
INTRODUCTION: Cost sharing can deter the use of health services and act as a potential contributor to racial/ethnic disparities in cancer. The Affordable Care Act required most health plans to cover, without cost sharing, preventive services, including colorectal cancer screening. Population-based data were used to estimate the impact of the Affordable Care Act's cost-sharing provision (together with other Affordable Care Act provisions targeting preventive care) on ethnic disparities in colorectal cancer screening, comparing Hispanics with non-Hispanics. METHODS: An interrupted time series quasi-experimental analysis was used to examine ethnic differences in colorectal cancer screening pre- and post-implementation of the Affordable Care Act (analysis performed in 2018). The study cohort included insured individuals aged 50-64 years who participated in the Medical Expenditure Panel Survey from 2007 through 2015 (n=44,343). RESULTS: During the pre-Affordable Care Act period, screening rates decreased annually for non-Hispanics by -0.38 per 100 adults per year (95% CI= -0.55, -0.22) but remained level for Hispanics (annual trend per 100 adults: 0.01, 95% CI= -0.34, 0.35). After cost sharing was eliminated in 2011, colorectal cancer screening rates increased for both Hispanics (by 1.29 per 100 adults, 95% CI=0.69, 1.89) and non-Hispanics (by 0.58 per 100 adults, 95% CI=0.18, 0.99). The difference in trend increases between Hispanics and non-Hispanics was not statistically significant (0.70%, 95% CI= -0.24, 1.64). CONCLUSIONS: These findings suggest that Affordable Care Act implementation resulted in increased colorectal cancer screening; however, the effect of the law was not significantly different between Hispanics and non-Hispanics. These results provide indications that more needs to be done to reduce racial/ethnic disparities in colorectal cancer screening.
