Objective: Due to the high mortality levels associated with the novel coronavirus, reliable predictors for determining disease mortality and severity are needed to permit the careful allocation of health services and for earlier clinical intervention and follow-up. The purpose of this study was to determine the predictive value of the C-reactive protein (CRP)/albumin ratio (CAR) and the fibrinogen/albumin ratio (FAR) in determining mortality and evaluate correlations between these values and thoracic computed tomography (CT) findings. Material and Methods: COVID-19 patients aged over 65 presenting to the emergency department of a tertiary training and research hospital between Oct 15, 2021, and Jan 15, 2022, were examined in this single-center, retrospective study. The study population was established based on inclusion and exclusion criteria. The patients’ mortality status and pulmonary involvement percentages were compared with their laboratory parameters. Results: The relationships between patients’ CAR and FAR values and mortality and disease severity were investigated. Cut-off points of 3.0 for CAR (AUC 0.767, sensitivity 76.5% and specificity 70.1%) and 14.4 for FAR (AUC 0.731, sensitivity 75.0% and specificity 69.0%) were determined for the prediction of mortality. In terms of prediction of disease severity, cut-off points were 4.2 for CAR (AUC 0.786, sensitivity 73.7%, and specificity 75.2%) and 15.2 for FAR (AUC 0.789, sensitivity 84.2%, and specificity 69.6%). Conclusion: Based on our study findings, CAR and FAR values may be useful in the early differentiation of mortality and pulmonary parenchymal involvement in elderly COVID-19 patients.
