The APACHE II (Acute Physiology and Chronic Health Evaluation II) score is a widely used severity-of-illness scoring system designed for adult patients in intensive care units (ICUs). Developed in 1985, it quantifies disease severity and predicts hospital mortality risk based on physiological measurements, age, and chronic health status. The score is calculated within the first 24 hours of ICU admission and is applicable across a broad range of adult critical care conditions. It is a cornerstone tool for risk stratification, quality assessment, and research in ICUs.
