Algorithm component	New York modela	Modified Colorado model	Raw SOFA score model
SOFA priority points	SOFA < 7: 1 point	SOFA < 6: 1 point	SOFA 1: 1 point
	SOFA 8–11: 2 points	SOFA 6-9: 2 points	SOFA 2: 2 points
	SOFA > 11: 3 points	SOFA 10–12: 3 points	SOFA 3: 3 points
		SOFA > 12: 4 points	SOFA score = priority points
Comorbidities priority points	None	Modified Charlson Comorbidity Indexb	None
Priority score calculation	SOFA score	SOFA prioritization + Charlson Comorbidity Index Score	SOFA score
Priority grouping based on priority score	High priority: 1	None	None
	Intermediate priority: 2
	Low priority: 3
Tie breakers	1st tie breaker: children	1st tie breaker: children, health care workers, and/or first responders	1st tie breaker: age

^aThe New York Algorithm exclusion criteria include the following: (1) unwitnessed cardiac arrest, recurrent arrest without hemodynamic stability, arrest unresponsive to standard interventions and measures; trauma-related arrest; (2) irreversible age-specific hypotension unresponsive to fluid resuscitation and vasopressor therapy; (3) traumatic brain injury with no motor response to painful stimulus (i.e., best motor response = 1); (4) severe burns where predicted survival is ≤10% even with unlimited aggressive therapy; and (5) any other conditions resulting in immediate or near-immediate mortality even with aggressive therapy. None of the patients in this cohort fell into this exclusion criteria.

^bOriginal and modified Comorbidity Index provided in Table S3.

^cLife cycle groupings (age, years) for Colorado also used for Raw SOFA model: 0–49 = 1 (highest priority), 50–59 = 2, 60–69 = 3, 70–79 = 4, and 80+ = 5 (lowest priority).
