The Simplified Acute Physiology Score (SAPS) is simplified version of APACHE and is comparable to APACHE II. APACHE II therefore is widely accepted and is one of the most validated score with readymade calculators available on the internet.
Because of its complexity it is not widely used. , APACHE IV, having 142 variables is a statistical model of logistic regression. This score has a wide lengthy range of 0 to 299, which makes it use difficult and time consuming. Mortality prediction is done on basis of daily clinical updates. It has 18 physiological variables including chronic ill health parameters. APACHE III, which is based on a larger database is an updated version of APACHE II. An increasing score was correlated with severity and subsequent risk of hospital death. This system was developed as a result of data available from 5815 intensive care admissions from 13 hospitals of USA between 19. ,, It is a scoring system aimed to determine the severity of disease and also to predict mortality of adult patients admitted to intensive care units. Available from: ĪPACHE II (Acute Physiology and Chronic Health Evaluation II) introduced in 1985 is a modification of the original APACHE developed in 1981.
