Glossary Definition

Last Updated: 2007-09-26


A set of measurable, clinical indicators, as well as diagnostic and therapeutic services reflecting the need for hospitalization. Rather than being based on diagnosis, they consider the level of illness of the patient and the services required; thus they serve as the criteria for all acute hospital care, regardless of location or size of the hospital. The criteria are grouped into 14 body systems, and there are 3 sets of criteria for each body system: Severity of Illness, Intensity of Service, and Discharge Screens.
