Introduction: Due to the high morbidity and mortality associated with COVID-19, clinical risk stratification tools have been developed for these patients, in order to predict progression to severe disease and/or mortality. In this study, the Quick COVID19 Severity Index Scale was compared with News2 as a predictor of mortality in adults with SARS-CoV-2 infection, specifying its diagnostic validity. Materials and methods: Observational, retrospective, analytical study of diagnostic tests. 255 patients were included, over 18 years of age, hospitalized in Hospital II - I Moyobamba with a diagnosis of COVID-19, with an oxygen requirement of ≤6 Lt/min, from January to December 2020. Results: 13% (32/255) of the patients died, with a predominance of males 62.5% (20/32), with an average age of 50 years, the bioclinical parameters evaluated did not show a statistically significant association, except for the blood glucose p: 0.01. Regarding the scales, considering a high score ≥7 points; Quick Covid-19 Severity Index has no significant association as a predictor of mortality, with a sensitivity and specificity of 43.75% and 63.23%, respectively; while NEWS-2 showed sensitivity of 87.50%; specificity of 50.67%; AUC 0.768 (CI: 0.684-0.853, p 0.00); that is, there is more than 75% probability of prognosis. Conclusion: the NEWS-2 scale statistically showed to be a good tool for the prognosis of mortality in patients infected with SARS - CoV - 2, it is suggested to carry out studies that confirm the findings of this research and assess its applicability and reproducibility in other populations.
