  COVID 19 MMCD Score to Predict Need for Dialysis

 
Input
 
Mechanical ventilation (before any dialysis) No (0)

Yes (11)
Sex Female (0)

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

Yes (1)

 
Result
 
 
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

 
 

 
Notes
  • In this calculator, mcg is the abbreviation for micrograms.

 
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.
