Mortality Due to Covid-19 in Hospitalized Patients: A Prediction Model Based on Different Risk Factors

Publication date: Sep 20, 2025

Another biological factor correlated with increased COVID-19 mortality is blood type A. 19Several clinical factors have been identified as contributors to increased COVID-19 mortality. In the case of chronic kidney disease, this study specifically determined that the association with COVID-19 mortality is present in patients at stages 4 and 5. Hyperglycemia, whether in patients with chronic diabetes or those experiencing the proinflammatory phase of COVID-19, has shown a strong correlation with mortality. Cheng et al58 found that fever, cough, dyspnea, and chest tightness were prevalent among patients who died early in their illness, whereas diarrhea was not a distinguishing feature. Perez et al59 reported that individuals in critical condition often presented with severe pneumonia, characterized by productive cough, fever and pleuritic pain. The Cox, Snel and Nagelkerke R2 values indicate that the variables included in the model explain 32% to 43% of the mortality due to COVID-19. Lower lymphocyte counts were also found to be a contributing factor. 8Since the emergence of the COVID-19 pandemic in 2019, extensive research has explored various aspects of the disease.
