Results
 
 
Factors  
Critical Illness Probability  
 
Decimal Precision  

 
     
 
Include literature references: Yes   No
 
Notes
  • Comorbidities includes COPD, hypertention, diabetes, coronary disease, kidney disease, cancer, cerebrovascular disease, hepatitis B and immunodeficiency.

 
Equations used
 
Factors = (Age * 0.0276) + (LDH * 0.0024) + (0.0562 * AbsoluteNeutrophilCount / AbsoluteLymphocyteCount) + (DirectBilirubin * 0.1376) + (Comorbidities * 0.4668) + CXR + Hemoptysis + Dyspnea + Unconscious + Cancer - 6.6127
CriticalIllnessProbability = 100 * e(Factors) / (1 + e(Factors))
