The Importance of Safety-Net Hospitals in Emergency General Surgery.

INTRODUCTION: Safety-net hospitals provide care to an inherently underprivileged patient population. These hospitals have previously been shown to have inferior surgical outcomes after complex, elective procedures, but little is known about how hospital payer-mix correlates with outcomes after more common, emergent operations. METHODS: The University HealthSystem Consortium database was queried for all emergency general surgery procedures performed from 2009 to 2015. Emergency general surgery was defined as the seven operative procedures recently identified as contributing most to the national burden. Only urgent and emergent admissions were included (n = 653,305). Procedure-specific cohorts were created and hospitals were grouped according to safety-net burden. Multivariate analyses were done to study the effect of safety-net burden on hospital outcomes. RESULTS: For all seven emergency procedures, patients at hospitals with a high safety-net burden were more likely to be young and black (p < 0.01 each). Patients at high-burden hospitals had similar severity of illness scores to those at other hospitals. Compared with lower burden hospitals, in-hospital mortality rates at high-burden hospitals were similar or lower in five of seven procedures (p = NS or < 0.01, respectively). After adjusting for patient factors, high-burden hospitals had similar or lower odds of readmission in six of seven procedures, hospital length of stay in four of seven procedures, and cost of care in three of seven procedures (p = NS or < 0.01, respectively). CONCLUSION: Safety-net hospitals provide emergency general surgery services without compromising patient outcomes or incurring greater healthcare resources. These data may help inform the vital role these institutions play in the healthcare of vulnerable patients in the USA.
