The usefulness of NEWS2 at day 7 of hospitalization in predicting COVID-19 evolution and as an early endpoint in therapeutic trials

• There is a need for reliable tools to predict the evolution of hospitalized patients suffering from COVID-19. • The likelihood of unfavourable evolution for patients hospitalized for COVID-19 with a National Early Warning Score 2 (NEWS2) below 7 at Day 7 of hospitalization is nearly non-existent. • Such a score could thus be used to allow earlier discharge of the patients and as a judgement criterion in therapeutic trials.
