Comparison of demographic and laboratory data of young and elderly patients who deceased due to COVID-19

Abstract

Introduction: Differences between young and elderly patients who deceased due to COVID-19 require further elucidation. The present study aimed to compare the differences between young and elderly patients who died from COVID-19. Material and Method: In this single-center cross-sectional study, patients included who had been diagnosed with COVID-19 and had died in the course of hospital follow-up. The following data were recorded. Demographic characteristics of the patients, date of diagnosis, length of diagnosis to death, the first place of hospitalization, duration of hospitalization at the clinical service and intensive care unit, blood parameters. Patients included in the study were divided into 2 groups, i.e., patients aged <65 and ≥65 years, and the relationship between the study data and these two groups were examined. Results: We included 369 patients. Prevalence of comorbid chronic diseases was significantly higher in the ≥65 years group (81.3% vs. 90.1%, p = 0.034). Prevalence of hypertension and chronic obstructive pulmonary disease was higher in the ≥65 years group (respectively, 72% vs. 84.4%, p = 0.013; 10.7% vs. 30.6%, p < 0.001). Intergroup comparison of laboratory parameters indicated that alanine aminotransferase and lactate dehydrogenase levels were higher in the <65 years group (respectively, p = 0.004; p = 0.020), whereas the creatinine levels were higher in the ≥65 years group (p < 0.001). Conclusion: This study captured the comorbidities, laboratory parameters, and duration of hospitalization of young and elderly patients, who died due to COVID-19. In the light of the study data, there was no significant intergroup difference.
