Early Warning Score (EWS)

Early Warning Score (EWS) is a guide used by medical services to quickly determine the degree of illness of a patient. It is a simple physiological score which may be used in initial assessment of a patient.

Pronunciation

Early Warning Score: /ˈɜːrli ˈwɔːrnɪŋ skɔːr/

Etymology

The term "Early Warning Score" is derived from its purpose in the medical field. It is designed to provide an "early warning" for deteriorating patient conditions, and "score" refers to the numerical value assigned based on the severity of the patient's condition.

Usage

The Early Warning Score is used to guide the response to clinical deterioration in adult patients in the hospital setting. It is based on the six most important vital signs: respiratory rate, oxygen saturation, temperature, blood pressure, pulse/heart rate, and level of consciousness. The EWS is calculated by adding the points from each parameter, with the total score determining the degree of patient illness.
