Much has been written about the use of the various Acute Physiology and Chronic Health Evaluation (APACHE) scoring methods. The APACHE score, a measure of physiologic derangement, chronic health status, and patient age, has not demonstrated consistent validity for surgical patients. There is substantial skepticism about the analytical role of this type of classification system. Koperna et al1 highlight the usefulness of APACHE II in risk stratification in emergency surgical patients.
