APACHE III
A method to compute a refined score known as APACHE III was published in 1991.
The score was validated on the dataset from 17,440 adult medical/surgical intensive care unit (ICU) admissions at 40 US hospitals.
The prognosis system of APACHE III have two options:
- 1. APACHE III Score
It provide initial risk classification of severely ill hospitalized patients in defined groups.
- 2. APACHE III predictive equation
It uses APACHE III Score. To establish the primary reason of ICU admission a reference data on 212 disease categories it's used. The patients is classified according etiology, major organ involved, surgical and medical status upon those categories. Patient´s data like Age, Sex, Race and preexisting comorbidities, are registred prior to established his health status. Location of treatment (operating room, recovery or emergency room, transfer or readmission from another hospital or ICU) previous to ICU admission to get the estimate risk for hospital mortality, for those ICU patients.
When possible data about the interval time between the patient´s arrival to hospital and the ICU admission time are collected.
To measure severity of disease 20 physiologic variable were selected.
APACHE III scores range from 0 to 299.
Reformulated Glasgow Coma parameters to eliminate almost identical scores for different neurological signs would give better and reliability results
