| apache | An acronym for acute physiology and chronic health evaluation, a scoring system using routinely collected data and providing an accurate, objective description for a broad range of intensive care unit admissions, measuring severity of illness in critically ill patients. This classification system is composed of two parts: a physiology score representing the degree of acute illness and a preadmission health evaluation indicating health status before acute illness. Development of apache began in 1978 under a 3-year research grant from the u.s. Health care financing administration. Revision and streamlining resulted in apache II. Its 12 routinely measured physiological variables were later amplified to become apache III. (12 Dec 1998) |
