Variables for Candidate Sepsis Criteria Among Encounters With Suspected Infection

Systemic Inflammatory Response Syndrome (SIRS) Criteria (Range, 0–4 Criteria)	Sequential [Sepsis-related] Organ Failure Assessment (SOFA) (Range, 0–24 Points)	Logistic Organ Dysfunction System (LODS) (Range, 0–22 Points)a	Quick Sequential [Sepsis-related] Organ Failure Assessment (qSOFA) (Range, 0–3 Points)
Respiratory rate, breaths per minute	PaO2/FiO2 ratio	PaO2/FiO2 ratio	Respiratory rate, breaths per minute
White blood cell count, 109/L	Glasgow Coma Scale score	Glasgow Coma Scale score	Glasgow Coma Scale score
Bands, %	Mean arterial pressure, mm Hg	Systolic blood pressure, mm Hg	Systolic blood pressure, mm Hg
Heart rate, beats per minute	Administration of vasopressors with type/dose/rate of infusion	Heart rate, beats per minute
Temperature, °C	Serum creatinine, mg/dL, or urine output, mL/d	Serum creatinine, mg/dL
Arterial carbon dioxide tension, mm Hg	Bilirubin, mg/dL	Bilirubin, mg/dL
