May aid ICU severity stratification; extends APACHE validation across groups but remains hypothesis-generating.
Does the APACHE classification system reliably measure severity of illness and predict therapeutic effort and mortality in critically ill patients?
The APACHE classification system provides a reliable, physiologically based method for measuring severity of illness in critically ill patients, correlating with therapeutic effort and mortality.
Knaus et al. (1981) studied this question.
