Hardman et al developed a model for predicting hospital mortality of a patient with a ruptured aortic aneurysm. This can help identify patients who are poor surgical candidates. The authors are from Royal North Shore Hospital in Australia.
Parameters:
(1) age in years
(2) serum creatinine
(3) loss of consciousness (coma) after arrival
(4) hemoglobin in g/dL
(5) ECG changes of ischemia

Interpretation:
• minimum score: 0
• maximum score: 5
• The higher the score the greater the hospital mortality.
