The association between the Patient Protection and Affordable Care Act and healthcare affordability among US adults with intellectual disability.

Abstract

Historically, US adults with intellectual disability (ID) experience worse healthcare access than the general population. However, the implementation of the Patient Protection and Affordable Care Act (ACA) may have reduced disparities in healthcare access. Using a pre-ACA 2011-2013 sample and a post-ACA implementation 2014-2016 sample from the National Health Interview Survey data, we examined the association between the ACA's introduction and healthcare access among adults with ID (N=623). Negative binomial regression models were used to test the association between the ACA and the total number of foregone healthcare services. Binary logistic regression was used to explore whether the ACA's implementation was associated with the increased likelihood of possessing health insurance as well as the decreased likelihood of any and particular measures of foregone healthcare services due to cost. The study provides evidence that the ACA's implementation was associated with the decreased likelihood of the total number and any foregone care services owing to cost. Findings also revealed that the ACA's implementation was associated with expansion of health insurance coverage and decreasing instances of foregone care services for medical care, dental care, specialist visit and mental care among adults with ID. However, persons with ID were still at a higher risk of foregone prescription medicines, follow-up medical care and eyeglasses due to cost in the post-ACA years. The study provides evidence that healthcare access among Americans with ID improved after the ACA's implementation. However, challenges in access to follow-up care, eyeglasses and prescription medicines persist and require policy solutions, which extend beyond the ACA's provisions.
