'''APACHE II''' ("'''Acute Physiology and Chronic Health Evaluation II'''") is a severity-of-disease classification system,<ref name="pmid3928249"/> one of several [[Intensive care unit|ICU]] [[medical scoring|scoring systems]]. It is applied within 24 hours of admission of a patient to an [[intensive care unit]] (ICU): an integer score from 0 to 71 is computed based on several measurements; higher scores correspond to more severe disease and a higher risk of death. The first APACHE model was presented by Knaus et al. in 1981.<ref name="pmid7261642"/>
