Evaluation of sequential organ failure assessment (SOFA) score efficiency in predicting the mortality of intensive care unit admitted COVID-19 patients

Abstract

Assessing the severity of the disease at the time of hospitalization can reduce the mortality of patients with coronavirus disease 2019 (COVID-19). For this stance, various scoring systems have been described to predict mortality rates. Sequential organ failure assessment (SOFA) is one of the scoring systems which have been used in this study. In order to calculate the SOFA score, demographic and characteristics information, clinical status, and laboratory findings were recorded from 154 patients with COVID-19, who have been admitted to the intensive care unit (ICU) for a period of 6 months. SOFA score was calculated in three time periods at the time of hospitalization, 72 hours after hospitalization, and the last day of hospitalization. Based on the outcome of the disease (death or recovery), patients were divided into two groups, and the results were analyzed in both groups. Statistical analysis has represented that the SOFA score was significantly higher in patients who died to compare with recovered ones in all time periods. Our findings suggest that SOFA scoring system can be used to predict mortality rate in ICU admitted COVID-19 patients.
