context_page_description: An early warning score is a guide used by medical services to quickly determine the degree of illness of a patient. It is based on the vital signs. Scores were developed in the late 1990s when studies showed that in-hospital deterioration and cardiac arrest was often preceded by a period of increasing abnormalities in the vital signs.
context_section_description: In the UK, the Royal College of Physicians developed the National Early Warning Score (NEWS) in 2012 to replace local or regional scores. The NEWS score is the largest national EWS effort to date and has been adopted outside the UK.
  A second version of the score was introduced in 2017. The revised version was optimised for the identification of sepsis, alternative oxygen targets in people with underlying lung disease, and the onset of delirium. Additional implementation guidance was issued in March 2020. While many hospitals still use other scores, it has been proposed that all healthcare organisations should use the same score in the interest of patient safety.
