Acute Physiology and Chronic Health Evaluation scoring system used to assess severity of illness in ICU patients.
Full Definition
APACHE II is a widely used severity-of-disease classification system that provides a general measure of disease severity based on current physiological measurements, age, and previous health status. The score ranges from 0 to 71, with higher scores corresponding to more severe disease and higher risk of hospital death. It is commonly referenced in surgical ICU documentation and research papers to stratify patient populations and predict outcomes.
Usage
Usage note: Always capitalize all letters and include the Roman numeral II.
