  Score Interpretation

-6 to 0 points: Low risk of mortality
1 to 3 points: Mild risk of mortality
4 to 7 points: Moderate risk of mortality
8 to 11 points: High risk of mortality
12 to 22 points: Very high risk of mortality


  Data action

Include literature references: Yes   No

  • This calculator represents findings from the literature referenced below. It is important to understand that these findings may not be representative of the experience in your local healthcare system.
  • Obesity is not objectively defined in the Bello-Chavolla study.[1]
  • COPD: chronic obstructive pulmonary disease.

Equations used
Score = AgeFactor + Diabetes + Obesity + Pneumonia + Chronic kidney disease + COPD + Immunosupression


Calculation Details and Variables
  • AgeFactor is assigned values by this ordered logic:
    • If Age ≥65 yr, AgeFactor = 3
    • Else if Age ≥40 yr, AgeFactor = 0
    • Else AgeFactor = -6.
  • Equation parameters such as Diabetes, 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.
