The Impact of the Affordable Care Act on Insurance Coverage and Stage Among Head and Neck Squamous Cell Carcinoma Patients

The purpose was to examine the change in percent uninsured and if there is change in T-stage, N-stage and overall-stage among nonelderly patients with newly diagnosed head and neck squamous cell carcinoma after the Affordable Care Act (ACA). The National Cancer Database was used for this study. Patients were divided between pre-ACA and post-ACA implementation with stratification between areas of ACA expansion versus non-expansion. A quasi-experimental difference-in-difference study design was undertaken. A total of 15,037 patients met the inclusion criteria. Between the pre-ACA and post-ACA periods, there was increase in proportion of percent insured with Medicaid coverage in patients residing in expansion region. There was a decrease in the proportion of patients who had advanced Tumor stage and Nodal stage decreased after implementation of ACA. With the implementation of ACA expansion, there is increased Medicaid coverage, corresponding to a decreased proportion of patients presenting with advanced T-stage and N-stage.
