Abstract

Purpose: Early recognition of corona virus disease 2019 (COVID-19) cases is the key to reducing mortality. In this study, we aimed to describe the relationship between the clinical, laboratory, and lung computed tomography (LCT) characteristics of patients with COVID-19 pneumonia and determine the severity of pneumonia in these patients.
Methods: The pneumonia severity index (PSI) score system, LCT images, and laboratory parameters at the time of first presentation to the emergency department were examined to assess the severity of COVID-19 pneumonia in 225 adult patients.
Results: In this study, a significant relationship was found between COVID-19-associated mortality and male gender (p=0.045), advanced age (p<0.001), a high neutrophil count in peripheral blood (p<0.001), a low eosinophil count (p<0.001), 5-49% lung involvement on LCT (p<0.001), and PSI Groups IV and V (p<0.001).
Conclusion: Using the multivariate logistic regression analysis, we determined the most significant factors for mortality as advanced age, low eosinophil and lymphocyte counts, increased lactate and ferritin levels, and PSI Group V.
