OBJECTIVE: Comorbidity frequency and mortality rates are higher in elderly patients with COVID-19. The disease is also more severe in elderly patients. This study aims to examine the characteristics of the COVID-19 disease, severity, comorbidities, and mortality rates in elderly patients by comparing them with nonelderly patients.

MATERIAL AND METHODS: This study was designed as a retrospective study. 469 patients who were followed up in outpatient, inpatient, and intensive care units with the diagnosis of COVID-19 between March 11, 2020, and June 01, 2020, were retrospectively included in the study. Patients were divided into two groups who were ≥65 years named as the “elderly group” and <65 years referred to as “nonelderly”. Survival data was generated from the death notification system on August 02, 2020.

RESULTS: A total of 469 patients including elderly(n=101) and nonelderly(n=368) were included in the study retrospectively. The inci- dence of severe pneumonia(31%/12.6%) and critical illness(16%/5.8%), comorbidity (85%/37.2%) and hospitalization time(8/5 days) were significantly higher in the elderly group(p<0.05). 23 (22.8%) of elderly patients and 27(7.3%) of nonelderly patients died (p=0.000). Mortality was found to be 3.5 times higher than in the non-elderly group. The expected survival time was 145.85 days(CI 95%:133- 158.66) in the elderly patients and 170.36 days(CI 95%:166-174.6) in the nonelderly patients (p<0.000). In ROC analysis, the sensitivity of age was 86%(73.3-94.2), specificity was 66.83%(62.1-71.3), and the cut-off>56 (AUC:0.775; p <0.001) in predicting mortality.

CONCLUSION: Mortality is high, comorbidities are more frequent, and the disease is more severe in elderly patients with COVID-19. Age above 56 can be used as a cut-off to predict mortality.
