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.
