Early warning score : ウィキペディア英語版 | Early warning score
An early warning score (EWS) is a guide used by medical services to quickly determine the degree of illness of a patient. It is based on data derived from four physiological readings (systolic blood pressure, heart rate, respiratory rate, body temperature) and one observation (level of consciousness, AVPU). ==The basis of an EWS== The resulting observations are compared to a normal range to generate a single composite score, for instance based on the following diagram: A score of five or more is statistically linked to increased likelihood of death or admission to an intensive care unit. Within hospitals, the EWS is used as part of a "track-and-trigger" system whereby an increasing score produces an escalated response varying from increasing the frequency of patient's observations (for a low score) up to urgent review by a rapid response or Medical Emergency Team (MET call).
