The APACH II score is given by the sum of the acute physiology score, the age points, and the chronic health points.

  1. Assigned if the patient has a history of severe organ system insufficiency or is immunocompromised.
  2. For non-operative or emergency post-operative patients, 5 points; and for elective post-operative patients, 2 points.
  3. Organ insufficiency or an immunocompromised state must have been evident before hospital admission and must conform to the following criteria:
    Liver: biopsy proven cirrhosis and documented portal hypertension, episodes of past upper gastrointestinal bleeding attributed to portal hypertension, or prior episodes of hepatic failure/encephalopathy/coma.
    Cardiovascular: New York Heart Association Class IV (i.e. symptoms of angina or cardiac insufficiency at rest or during minimal exertion).
    Respiratory: chronic restrictive, obstructive, or vascular disease resulting in severe exercise restriction, i.e. Unable to climb stairs or perform household duties, or documented chronic hypoxia, hypercapnia, secondary polycythemia, severe pulmonary hypertension (>40 mmHg), or respirator dependency.
    Renal: receiving chronic dialysis.
    Immunocompromised: the patient has received therapy that suppress resistance to infection, e.g. immunosuppression, chemotherapy, radiation, long term or recent high dose steroids, or has a disease that is sufficiently advanced to suppress resistance to infection, e.g. Leukemia lymphoma, AIDS.
