Stratification of prognosis in granulocytopenic patients with hematologic malignancies using the APACHE-II severity of illness score. 
The APACHE-II (acute physiology and chronic health evaluation) severity of disease classification system was used to stratify prognosis of granulocytopenic patients with hematologic malignancies.  A total of 146 admissions were retrospectively reviewed.  In 26 ICU admissions, mortality was 69.2%; in 120 admissions to the ward, mortality was 15.8%.  The APACHE-II score successfully stratified prognosis in both ward and ICU settings.  Respiratory failure and the presence of pneumonia on chest x-ray were identified as poor prognostic factors.  ICU patients admitted for monitoring or postoperative care had a better prognosis than those admitted for severe cardiopulmonary compromise.  We suggest that the APACHE-II system is useful for stratifying prognosis for clinical research in this group of patients, although it remains to be shown whether it will be useful in predicting the prognosis of individual patients.
