Survival to hospital discharge by age, race, and ethnicity by allocation protocol in a Monte Carlo simulation of a 50% ventilator shortage. Black refers to non-Hispanic Black patients and White refers to non-Hispanic White patients. In lottery allocation, survival was 40% in patients younger than 40 years compared with 24% in patients 80 years or older. In youngest-first, survival was 76% in patients younger than 40 years compared with 2.6% in patients 80 years or older. In the multiprinciple protocol with an age tiebreaker, survival was 53% in patients younger than 40 years compared with 19% in patients 80 years or older. In lottery allocation, survival was not significantly different between racial and ethnic groups (average survival 31%). In the SOFA-only protocol, survival to discharge was 29% for Black patients compared with 35% for Hispanic patients and 36% for White patients. In the multiprinciple protocol, survival was 29% for Black patients compared with 38% for Hispanic patients and 34% for White patients. SOFA = Sequential Organ Failure Assessment.
