EWS Full Form in Medical is early warning score. Early warning scores, also known as EWS, are used by medical professionals as a tool for rapidly determining the severity of a patient’s condition. It is dependent on the vital indicators, which include the temperature, pulse rate, heart rate, respiration rate, and oxygen saturation.
In the late 1990s, when studies demonstrated that in-hospital worsening and heart attack were frequently followed by a time of increasing anomalies in the vital signs, scores were constructed as a result of these findings.
In hospitals, the EWS is utilized as portion of a “track-&-trigger” system, in which an increasing score generates an escalated response. These responses range from raising the number of patient observations (for a low score) all the way up to emergency review by a fast reaction/ Medical Emergency Team.
The worries of the nursing staff could also be used as a trigger for such a call, given that changes in nursing staff concerns may anticipate changes in vitals.
At the annual meeting of the Intensive Care Society in May 1997, a group of researchers working at James Paget Hospital in Norfolk, United Kingdom, produced the first known EWS and presented it at that meeting.
