MI, myocardial infarction; CHF, congestive heart failure; COPD, chronic obstructive pulmonary disease.

a

APACHE II—Acute Physiology and Chronic Health Evaluation II (21)—is a severity of illness scoring system, and these data were calculated using the most abnormal parameters during the first 24 hours following admission to the intensive care unit. APACHE II scores range from 0 (best) to 71 (worst).

b

SOFA—Sequential Organ Failure Assessment (23, 24)—is an organ failure scoring system which was also calculated using the most abnormal parameters during the first 24 hrs following admission to the intensive care unit. SOFA scores range from 0 (best) to 24 (worst);

c

The admission diagnoses were recorded by the patients’ medical team as the diagnoses most representative of the reason for intensive care unit admission. Patients were sometimes given more than one admission diagnosis by the medical team resulting in column totals over 100%.
