Introduction: The impact of safety net (SN) hospitals relative to racial and healthcare disparities remains largely unknown.
Methods: Using the Nationwide Inpatient Sample, adults undergoing coronary artery bypass grafting, colectomy, or total hip arthroplasty were identified. Multivariable regression analysis was performed to determine association between SN burden and outcomes. Within each SN burden tier, the association between race/ethnic group and outcomes was defined.
Results: Overall 865,648 patients were identified. After adjustment for potential confounders, patients operated at the highest SN burden hospitals had increased odds of complications (OR 1.14, 95%CI 1.10-1.18), death (OR 1.41, 95%CI 1.31-1.52), FTR (OR 1.36, 95%CI 1.25-1.47) and a never event (OR 1.57, 95%CI 1.47-1.68). Irrespective of hospital SN burden, racial minorities had greater odds of a complication, and prolonged LOS compared to whites (p < 0.05).
Conclusion: While overall degree of safety net burden was associated with worse overall outcomes, SN hospitals did not mitigate racial disparities experienced by minority patients.
