Sequential Organ Failure Assessment (SOFA) Score

Use the worst value in a 24-hour period.
P_aO₂	mm Hg
F_iO₂
Platelet Count	10³/µL
Glasgow Coma Score	points
Bilirubin, Total	mg/dL
Level of Hypotension (Vasopressor Status For ≥ 1 Hr)	No Hypotension +0 points MAP < 70 +1 point On vasopressors, dopamine < 5 µg/kg/min or dobutamine (any dose) +2 points Dopamine > 5 µg/kg/min or Epi/Norepi < 0.1 µg/kg/min +3 points Dopamine > 15 µg/kg/min or Epi/Norepi > 0.1 µg/kg/min +4 points
Creatine (or Urine Output, Use Worst Value)	Cr < 1.2 mg/dL (< 106 µmol/L) +0 points Cr 1.2-1.9 mg/dL (106-168 µmol/L) +1 point Cr 2.0-3.4 mg/dL (177-301 µmol/L) +2 points Cr 3.5-4.9 mg/dL (309-433 µmol/L) or Urine Output < 500ml/day +3 points Cr > 5.0 mg/dL (> 442 µmol/L) or Urine Output < 200ml/day +4 points
SOFA Score:
An initial SOFA score <9 predicted a mortality <33%, while an initial score >11 prediction of mortality of 95%.
