  COVID-19 MMCD Score to Predict Need for Dialysis

Mechanical ventilation (before any dialysis) No (0)

Yes (11)
Sex Female (0)

Male (1)
Creatinine on admission  
Diabetes No (0)

Yes (1)

Important: Inputs must be complete to perform calculation.

MMCD Score  

Include literature references: Yes   No

  MMCD Score Interpretation

0 to 10 points: 0 to 14.9% probability of dialysis
11 to 14 points: 15 to 49.9% probability of dialysis
15 to 23 points: ≥50% probability of dialysis


  • 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.

Equations used
MMCDScore = Mechanical ventilation (before any dialysis) + Sex + CreatinineFactor + Diabetes


Calculation Details and Variables
  • Equation parameters such as Mechanical ventilation (before any dialysis), 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.
  • CreatinineFactor is assigned values by this ordered logic:
    • If Creatinine on admission ≥5 mg/dL CreatinineFactor = 10
    • Else if Creatinine on admission ≥3.5 mg/dL CreatinineFactor = 4
    • Else if Creatinine on admission ≥2 mg/dL CreatinineFactor = 2
    • Else if Creatinine on admission ≥1.2 mg/dL CreatinineFactor = 1
    • Else CreatinineFactor = 0.
