Apache II Score / Approximate Mortality Interpretation

  • For the APACHE II score to be correct, a value must be selected for every variable.
  • The numbers in the parentheses represent the point value assigned to each clinical parameter above. The Apache Score is the sum of these points.
  • Chronic Dx includes biopsy proven cirrhosis and documented portal hypertension; past upper GI bleeding attributed to portal hypertension; prior hepatic failure; prior hepatic encephalopathy; NYHA class IV; chronic restrictive, obstructive, or vascular lung disease resulting in severe exercise restriction; documented hypoxemia or hypercapnia; secondary polycythemia; severe pulmonary hypertension (>40 mmHg); ventilator dependence; chronic hemodialysis.
  • Chronic Dx also includes immunosuppression from chemotherapy, radiation therapy, long-term or recent high-dose steroids, immunodeficiency (eg, leukemia, lymphoma, AIDS).
