The Affordable Care Act: Long-Term Financial Impact on a Level I Trauma Center

Prior studies of the impact of the Affordable Care Act on reimbursement for inpatient trauma care do not include disproportionate share hospital (DSH) funding. Because trauma centers and other safety-net hospitals are sensitive to any changes in financial support, it is essential to include DSH funding in evaluating overall reimbursement. This study analyzes the long-term financial trends, including DSH, of a level I trauma center in Ohio, a state that expanded Medicaid.

Charges, reimbursement, sources of insurance coverage, Injury Severity Scores, and DSH funding for the trauma patient population of an Ohio American College of Surgeons level 1 trauma center were studied from 2012 to 2017. Data were collected from Transition Systems, Inc.

During 2012-2017, self-pay patient cases decreased from 15.0% to 4.1% and commercial insurance patients decreased from 34.2% to 27.6%. The percentage of Medicaid patients increased from 15.5% to 27.1%; however, Medicaid reimbursement average per case declined from $17,779 in 2012 to $10,115 in 2017 (a decline of 43.1%). Self-pay charges decreased from $22.0 million to $6.7 million. Total DSH funding, compensation given to hospitals that disproportionately treat underserved populations, decreased 17.4%.

Self-pay charges and self-pay patients decreased dramatically; Medicaid patients and charges increased substantially in the years after the implementation of the Affordable Care Act at our trauma center. However, there was a decrease in commercial insurance, which had the highest reimbursement for our hospital, and a significant decline in DSH, a critical supplemental source of funding for safety-net hospitals.
