Abstract

Background: The Affordable Care Act (ACA) increased Medicaid coverage of Emergency General Surgery (EGS). We hypothesized that despite the ACA, racial and geographic disparities persisted for EGS admissions.

Methods: The Nationwide Inpatient Sample was queried from 2012 through Q3 of 2015 for Non-Medicare patient EGS admissions. Difference-in-Differences analyses (DID) compared payors, complications, mortality and costs in pre-ACA years (2012-2013) and post-ACA years (2014-2015Q3).

Results: EGS cases fell 9.1% from 1,711,940 to 1,555,033 NIS-weighted cases. Hispanics were still most likely to be uninsured but had improved coverage (OR 0.92, 95% CI: 0.88-0.96, p < 0.001). Risk of uninsured EGS admissions from the South region persisted (OR 1.52, 95% CI: 1.46-1.58, p < 0.001). Uninsured EGS patients had higher DID increased mortality than insured patients (0.31% higher, P = 0.003). Insured group DID costs increased more rapidly than in self-pay Patients (6.0% higher, P = 0.008) CONCLUSIONS: Post ACA, risk of uninsured EGS admissions remained highest in the South, in males, and Hispanics.
