Key Points Question What are the characteristics of intensive care unit admissions identified by 2 proposed pandemic ventilator allocation triage guidelines using Sequential Organ Failure Assessment scores when applied retrospectively to critically ill US patients who received mechanical ventilation? Findings In this cohort study of 40 439 admissions to intensive care units that received mechanical ventilation, the New York State guideline identified 9% who would likely meet criteria for the lowest priority for ventilator allocation compared with 4% from the original White and Lo guideline. Only 655 admissions (1.6%) were in the lowest priority category for both guidelines, with 39% survival to hospital discharge for admissions identified as lowest priority using the New York State guideline compared with 56% for admissions identified using White and Lo. Meaning Two distinct approaches to triage for mechanical ventilation showed little agreement, suggesting that further clinical assessment of different potential criteria for triage decisions is important to ensure equitable allocation of resources.
