Aim: COVID-19 caused many deaths, and its socioeconomic impact continues. Hospital mortality is generally known, but information on 1-year mortality is
limited. This study aimed to measure all-cause mortality rates in hospitalized and 1-year follow-up COVID-19 patients and to evaluate the factors affecting
these rates.
Material and Methods: PCR-positive patients’ demographic, clinical, and laboratory characteristics were retrospectively analyzed. Hospitalization duration and
mortality data were recorded. Discharged patients’ polyclinic, follow-up, and mortality status within one-year were evaluated.
Results: The study included 201 patients, with a mean age of 63.12±14.5 years, and 59.2% were male. Logistic regression analysis identified several factors
affecting hospital mortality, including male gender, smoking, lactate-dehydrogenase, and ferritin. Further analyses indicated that advanced age, low-oxygen
saturation, high-sodium levels, low-potassium levels, low-hemoglobin), elevated-white-blood cell count, reduced-platelet count, increased INR and D-Dimer
count, and elevated-CRP (C-reactive protein) levels were significant factors influencing hospital mortality. Mortality within 1-year was associated with factors
including male gender, diabetes, low-oxygen saturation, elevated-AST levels, elevated-ALT levels, elevated-ferritin levels, and hospitalization length. Those who
died within one year were more likely to have been hospitalized in intensive-care unit, required oxygen support, and were smokers.
Discussion: Hospital mortality was associated with impaired laboratory parameters and smoking, whereas 1-year mortality was associated with intensivecare,
oxygen requirements, and diabetes.
