APACHE II Score for ICU Mortality
Calculates the APACHE-II score to estimate predicted mortality.
The Apache-II Score provides an estimate of ICU mortality based on a number of laboratory values and patient signs taking both acute and chronic disease into account. Note: The data used should be from the initial 24 hours in the ICU, and the worst value (furtherest from baseline/normal) should be used.
The following defines "chronic organ insufficiency" and immunocompromise:
- Liver insufficiency
- Biopsy proven cirrhosis
- Documented portal hypertension
- Episodes of past upper GI bleeding attributed to portal hypertension
- Prior episodes of hepatic failure / encephalopathy / coma.
- Cardiovascular
- New Heart Association Class IV Heart Failure
- Respiratory
- Chronic restrictive, obstructive or vascular disease resulting in severe exercice restriction, i.e. unable to climb stairs or perform household duties.
- Documented chronic hypoxia, hypercapnia, secondary polycythemia , severe pulmonary hypertension (> 40 mmHg), or respirator dependency.
- Renal
- Receiving chronic dialysis
- Immunosuppression
- The patient has received therapy that suppresses resistance to infection e.g. immuno-suppression, chemotherapy, radiation, long term or recent hight dose steroids, or has a disease that is sufficiently advanced to suppress resistance to infection, e.g. leukemia, lymphoma, AIDS.
