Abstract

Background: The Patient Protection and Affordable Care Act (ACA), enacted in 2010, expanded private insurance coverage of young adults through the dependent coverage provision. This policy's implications for patients with cystic fibrosis (CF) are unknown. Methods: The CF Foundation Patient Registry was used to identify patients seen at CF centers, 3 years before and after ACA implementation. Patients were grouped according to eligibility for the dependent care provision (18–25 years old in 2010) or ineligibility (26–35 years old). Year-level difference-in-difference logistic regressions evaluated the association between ACA enactment and insurance status (private, public, or no insurance). Routine annual care consistent with CF Foundation guidelines (≥4 clinic visits, ≥4 respiratory cultures, and ≥2 pulmonary function tests/year) was a secondary outcome. Results: The analysis included 4,024 and 3,132 patients in the eligible and ineligible groups, respectively (35,353 patient-years). In the eligible group, 62% had private insurance before and after ACA; 18% had public insurance before and after ACA; and 5% switched from public to private insurance. In the eligible group, lack of insurance coverage became more common in the post-ACA period (relative risk ratio vs. private insurance [RRR] = 1.95; 95%CI: 1.57, 2.43; P < 0.001). Public insurance coverage also became more common (RRR = 1.50; 95%CI: 1.39, 1.62; P < 0.001). Use of routine care increased post-ACA, but more strongly in the ineligible group than in the eligible group. Conclusions: The ACA dependent coverage provision did not increase private insurance coverage or use of routine care among CF patients who were potentially affected by this policy.
