  Sequential Organ Failure Assessment (Modified): mSOFA Score

 
Input
 
O2 Saturation  
FIO2  
Jaundice No (0)

Yes (3)
Blood Pressure Hypotension absent (0)

Mean arterial pressure <70 mmHg (1)

On Dopamine ≤5 mcg/kg/min or any Dobutamine (2)

On Dopamine >5 mcg/kg/min, Epinephrine <=0.1 mcg/kg/min or Norepinephrine <=0.1 mcg/kg/min (3)

On Dopamine >15 mcg/kg/min or Epinephrine >0.1 mcg/kg/min or Norepinephrine >0.1 mcg/kg/min (4)
Glasgow Coma Score  
Creatinine

  mSOFA Score Interpretation

 
0 to 7 points: 4% Mortality
8 to 11 points: 31% Mortality
12 to 19 points: 58% Mortality

 
 

 
Equations used
 
O2 Saturation/FIO2 = 100 * O2 Saturation / FIO2
mSOFAScore = safiFactor + Jaundice + BloodPressure + GlasgowComaScoreFactor + CreatinineFactor

 

 
Calculation Details and Variables
  • Equation parameters such as Jaundice, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (0), represent the values that will be used.
  • GlasgowComaScoreFactor is assigned values by this ordered logic:
    • If Glasgow Coma Score <6 points GlasgowComaScoreFactor = 4
    • Else if Glasgow Coma Score ≤9 points GlasgowComaScoreFactor = 3
    • Else if Glasgow Coma Score ≤12 points GlasgowComaScoreFactor = 2
    • Else if Glasgow Coma Score ≤14 points GlasgowComaScoreFactor = 1
    • Else GlasgowComaScoreFactor = 0.
  • CreatinineFactor is assigned values by this ordered logic:
    • If Creatinine ≥5 mg/dL CreatinineFactor = 4
    • Else if Creatinine ≥3.5 mg/dL CreatinineFactor = 3
    • Else if Creatinine ≥2 mg/dL CreatinineFactor = 2
    • Else if Creatinine ≥1.2 mg/dL CreatinineFactor = 1
    • Else CreatinineFactor = 0.
  • safiFactor is assigned values by this ordered logic:
    • If O2 Saturation/FIO2 ≤150 safiFactor = 4
    • Else if O2 Saturation/FIO2 ≤235 safiFactor = 3
    • Else if O2 Saturation/FIO2 ≤315 safiFactor = 2
    • Else if O2 Saturation/FIO2 ≤400 safiFactor = 1
    • Else safiFactor = 0
