Exploring the performance of the National Early Warning Score (NEWS) in a European emergency department

Measures of acute physiology, comorbidity and functional status to differentiate illness severity and length of stay among acute general medical admissions: a prospective cohort study

“…Emergency department overcrowding could not be controlled for in our study but its persistence as a problem in many healthcare systems reinforces the need to help staff make high‐quality decisions with minimal information. To this end, significant efforts have been made to prognosticate patient outcomes using measures available at the point of presentation with acute illness . Early warning scores of various design have been used singly or as part of multi‐faceted early warning systems to guide early identification and treatment of deteriorating patients in emergency departments and hospital wards .…”

“…To this end, significant efforts have been made to prognosticate patient outcomes using measures available at the point of presentation with acute illness . Early warning scores of various design have been used singly or as part of multi‐faceted early warning systems to guide early identification and treatment of deteriorating patients in emergency departments and hospital wards . While heterogenous study designs and interventions have made the absolute effect of these scores on patient outcomes difficult to assess, they do appear to be useful in guiding prioritisation of assessment, predicting need for hospital admission and predicting adverse outcomes among patients with the sepsis syndrome, regardless of source …”

Application of the National Early Warning Score (NEWS) as a stratification tool on admission in an Italian acute medical ward: A perspective study

“…The National EWS (NEWS) was designed and validated in the United Kingdom by using evidence arising from existing tools (including the published VitalPAC EWS) to allow for a common and standardised assessment at a national level, to drive the “step change” required in the assessment and response to acute illness . The use of track and trigger systems and NEWS to ensure consistency in early recognition and response to patient deterioration has also been recommended in other countries …”

A Comparison of the Ability of the Physiologic Components of Medical Emergency Team Criteria and the U.K. National Early Warning Score to Discriminate Patients at Risk of a Range of Adverse Clinical Outcomes*

“…The RCPL recommends that NEWS values of >7 should prompt assessment by an RRT (9). NEWS demonstrates better ability than other published EWSS to discriminate patients at risk of a range of clinical outcomes (6) and has been validated outside its development site (10)(11)(12)(13).…”
