APACHE II Score
Acute Physiology and Chronic Health Evaluation II
The APACHE II score (Acute Physiology and Chronic Health Evaluation II) is a classification system used to measure disease severity in critically ill patients, especially those admitted to intensive care units (ICUs). It combines acute physiological data, age, and chronic health history to provide an estimate of hospital mortality risk. The score is applied within the first 24 hours of patient admission.
