Objective: perform the predictive validity of National Early Warning Score 2 - Brazilian version (NEWS 2 - BR) in discharge and death outcomes in patients with COVID-19. Method: crosssectional study with predictive validity analysis. Social-demographical and clinical variables, outcomes and the score components were collected with an electronic health record and analyzed through descriptive and inferential statistics. Outcomes: 400 patients were included, with median age of 61 years. The score, at the moment of admission, had a median of 5 points, with a range from 0 to 21. There is an association between the highest scores and the death outcome and the lowest scores and the discharge outcome. The predictive validity of NEWS 2 - BR for death was established by the analysis of the ROC curve and the most accurate cut-off point was six points. Conclusion: The Brazilian version of NEWS 2 is a valid score to assess patients with COVID-19. [ABSTRACT FROM AUTHOR]
