Disparities in access to cancer surgery after Medicaid expansion.
Abstract
INTRODUCTION\nThe Affordable Care Act (ACA) expanded Medicaid eligibility to persons with income up to 138% of the federal poverty line. We investigated how Medicaid expansion (ME) impacted the access to cancer-specific surgical care in the US.\n\n\nMETHODS\nWe used a nationwide population-based database (SEER) to identify patients with the 8 most prevalent cancers between 2007 and 2015. Adjusted difference-in-differences (DiD) and multivariate regression were used for statistical analysis.\n\n\nRESULTS\nA total of 1,008,074 patients were included. Patients post-ME were diagnosed at an earlier stage (pre-ME, 27.6%; post-ME, 31.1%; P\xa0<\xa00.001), and lack of insurance coverage decreased from 5.5% to 2.6% (P\xa0<\xa00.001). Lower-SES population had improved access to surgical care (attributable benefit\xa0+3.18%; P\xa0<\xa00.001). ME was an independent predictor of access-to-surgery (OR, 1.45; P\xa0<\xa00.001), whereas African-American and Hispanic race were negative predictive factors.\n\n\nCONCLUSION\nAfter ME, the population without insurance coverage decreased. This was associated with earlier cancer diagnosis and improved access to surgery in patients from economically disadvantaged communities.
