Racial Differences in Sepsis Mortality at U.S. Academic Medical Center–Affiliated Hospitals

Objectives: To determine the racial disparities in severe sepsis hospitalizations and outcomes in U.S. academic medical center–affiliated hospitals. Design: Retrospective analysis of sepsis hospitalizations. Settings: U.S. academic medical center–affiliated hospitals participating in Vizient Consortium from 2012 to 2014. Patients: Sepsis hospitalizations using International Classification of Diseases, Ninth revision, discharge diagnoses codes defined by the Angus method. Interventions: None. Measurements and Main Results: We compared rates of sepsis hospitalization, ICU admission, organ dysfunction, and hospital mortality between blacks and whites. We repeated the analyses stratified by community-acquired, healthcare-associated, and hospital-acquired sepsis subtypes. Of 10,244,780 hospitalizations in our cohort, 1,114,386 (10.9%) had sepsis. Sepsis subtypes included community-acquired sepsis (61.8%), healthcare-associated sepsis (23.8%), and hospital-acquired sepsis (14.4%). Although the proportion of discharges with sepsis was lower for blacks than whites (106.72 vs 109.43 per 1,000 hospitalizations; p
