Apache (Medicine)

Apache (pronounced: /əˈpætʃi/) is an acronym used in medicine, specifically in Intensive Care Units (ICU) to denote the Acute Physiology and Chronic Health Evaluation, a severity of disease classification system. The etymology of the term is derived from its full form, Acute Physiology and Chronic Health Evaluation.

Acute Physiology and Chronic Health Evaluation

The Acute Physiology and Chronic Health Evaluation (APACHE II) is a severity of disease classification system (pronounced: /əˈkjuːt faɪˈzɪɒlədʒi ænd krɒnɪk hɛlθ ɪˈvæljʊˌeɪʃən/), an empirically derived scoring system that provides a general measure of disease severity in hospitalized patients, particularly those in the ICU.

The APACHE II system, a development of the original APACHE system, was designed in 1985 and is able to provide an estimate of patient mortality and length of stay in the ICU. The system uses a point score based upon initial values of 12 routine physiological measurements, age, and previous health status to provide a single score for each patient's severity of illness.
