NATIONAL EARLY WARNING SCORE 2 Y COVID-19 SEVERITY INDEX, PREDICTORES DE MORTALIDAD EN EL SARS-COV2

Abstract

The COVID-19 pandemic has led to a global health emergency. Accurate assessment of disease severity is crucial for its management. In this context, prognostic scales such as the National Early Warning Score 2 (NEWS-2) and the COVID-19 Severity Index (CSI) have emerged as significant tools. This study aims to evaluate the effectiveness of the NEWS-2 and CSI scales as mortality predictors in individuals infected with SARS-CoV-2. For this purpose, a literature review of research on prognostic scales in COVID-19 patients was conducted, selecting relevant articles published up to January 2023. The results were analyzed to determine the accuracy of NEWS-2 and CSI in predicting mortality. Evidencing that, roth NEWS-2 and CSI were shown to be effective tools for predicting mortality in individuals with COVID-19. However, CSI demonstrated higher sensitivity and specificity, especially when supplemented with additional parameters such as biomarkers and risk factors. It is concluded that, NEWS-2 and CSI are useful for predicting mortality in COVID-19, with CSI being more precise. The inclusion of biomarkers and risk factors improves their predictive capacity. Further research is needed to validate and enhance these tools in the clinical management of the disease.
