Mahal AR, Chavez J, Yang DD, et al. - Researchers examined nonelderly adults with a common cancer after Affordable Care Act (ACA) implementation for sociodemographic disparities in insurance coverage. From 2010 to 2014, they identified in total, 109,182 patients aged 18 to 64 years diagnosed with a common cancer (lung, breast, or prostate cancer). A decline in uninsured rates was observed following ACA implementation, with the greatest rate reductions seen in association with traditional Medicaid expansion. Observations suggest a correlation of traditional Medicaid expansion with the elimination of racial and socioeconomic insurance coverage gaps. Results thereby suggest the possible benefits and challenges of the ACA and its provisions, and could guide ongoing policy.
