Nineteen different departments admitted a total of 613 patients to the surgical intensive care unit. Predicted mortality was 22.9%; actual mortality was 15.7%. APACHE II generated reports which included analysis by age, mortality risk, department, primary physician, and diagnosis. We recommend reporting intensive care unit outcome by APACHE criteria to allow more meaningful comparisons of data and standardization of quality assurance programs. Finally, we present a critical review of the current APACHE II system and describe developments to be included in APACHE III.
