Equations used
 
PaO2/FIO2 = 100 * PaO2 / FIO2
Pressure Adjusted Heart Rate = HeartRate * CentralVenousPressure / MeanArterialPressure
MODSScore = PaO2/FIO2Factor + plateletsFactor + biliFactor + Pressure Adjusted Heart RateFactor + renalFactor + gcsFactor

 

 
Calculation Details and Variables
  • PaO2/FIO2Factor is assigned values by this ordered logic:
    • If PaO2/FIO2 >300 PaO2/FIO2Factor = 0
    • Else if PaO2/FIO2 ≥226 PaO2/FIO2Factor = 1
    • Else if PaO2/FIO2 ≥151 PaO2/FIO2Factor = 2
    • Else if PaO2/FIO2 ≥76 PaO2/FIO2Factor = 3
    • Else PaO2/FIO2Factor = 4
  • Pressure Adjusted Heart Rate Factor is assigned values by this ordered logic:
    • If Pressure Adjusted Heart Rate ≤10 Pressure Adjusted Heart Rate Factor = 0
    • Else if Pressure Adjusted Heart Rate ≤15 Pressure Adjusted Heart Rate Factor = 1
    • Else if Pressure Adjusted Heart Rate ≤20 Pressure Adjusted Heart Rate Factor = 2
    • Else if Pressure Adjusted Heart Rate ≤30 Pressure Adjusted Heart Rate Factor = 3
    • Else Pressure Adjusted Heart Rate Factor = 4
  • plateletsFactor is assigned values by this ordered logic:
    • If Platelets >120 x10(3)/mcL plateletsFactor = 0
    • Else if Platelets ≥81 x10(3)/mcL plateletsFactor = 1
    • Else if Platelets ≥51 x10(3)/mcL plateletsFactor = 2
    • Else if Platelets ≥21 x10(3)/mcL plateletsFactor = 3
    • Else plateletsFactor = 4.
  • biliFactor is assigned values by this ordered logic:
    • If Bilirubin ≤20 mcmol/L biliFactor = 0
    • Else if Bilirubin <61 mcmol/L biliFactor = 1
    • Else if Bilirubin <121 mcmol/L biliFactor = 2
    • Else if Bilirubin ≤240 mcmol/L biliFactor = 3
    • Else biliFactor = 4.
  • renalFactor is assigned values by this ordered logic:
    • If Creatinine ≤100 mcmol/L renalFactor = 0
    • Else if Creatinine <201 mcmol/L renalFactor = 1
    • Else if Creatinine <351 mcmol/L renalFactor = 2
    • Else if Creatinine ≤500 mcmol/L renalFactor = 3
    • Else renalFactor = 4.
  • gcsFactor is assigned values by this ordered logic:
    • If Glasgow Coma Score >14 points gcsFactor = 0
    • Else if Glasgow Coma Score >12 points gcsFactor = 1
    • Else if Glasgow Coma Score >9 points gcsFactor = 2
    • Else if Glasgow Coma Score >6 points gcsFactor = 3
    • Else gcsFactor = 4.
