Initial MEWS score to predict ICU admission or transfer of hospitalized patients with COVID-19: a retrospective study.
2020
Early warning scores (EWS) were introduced in early 2001 to identify patients at risk of deterioration in a busy clinical environment as a track-and-trigger system where an increasing score produced an escalated response.1Subbe C.

Since serious adverse events in hospitalized patients are often preceded by signs of clinical deterioration, we believed MEWS scores could be used to predict events, such as cardiopulmonary arrest. As the coronavirus pandemic continues, could MEWS provide any usefulness in predicting ICU level care among hospitalized COVID-19 patients?
