COVID-19 Severity Index (SI): is it a sensitive predictor score for disease outcome in hospitalized patients?

Introduction. The COVID-19 pandemic showed the wide ranging of coronavirus disease prognosing, hence clinical identification of patients who are at risk of poor outcomes is a priority. But there is no proven prognostic scoring system yet. COVID-19 SI was developed as a triage tool, that could be used by healthcare personnel to identify high-risk patients. ¹ Aim. To estimate whether COVID-19 SI could predict the disease outcome in hospitalized patients with coronavirus disease already on admission? Methods. The study was a single-center retrospective analysis based on data of 632 COVID-19 patients admitted to the City Hospital № 4 (Dnipro) from August to October 2021. The patients’ SI on admission and disease outcome were analyzed and statistically processed. Results. Distribution of survivors and nonsurvivors regarding clinical risk in accordance with SI is presented in Table 1. The sensitivity of SI as prognostic score totaled 37 %; specificity – 52,7 %. Table 1. Distribution of survivors and nonsurvivors regarding clinical risk in accordance with SI. Conclusions. The study confirmed COVID-19 SI as a good triage tool on admission, but it has low sensitivity and specificity as prognostic score. References: 1. Huespe, I. et al.
