Objectives. The experience accumulated in the last two years shows that the prevention of COVID-19 in people with comorbidities (protective measures, vaccination, etc.) still remains a public health priority. In this context, the aim of our study was to perform a retrospective, observational study in order to assess the time-to-death and risk factors of mortality among COVID-19 patients. Materials and Methods. The study was conducted on 177 patients admitted to Oradea Emergency County Hospital, Bihor, Romania, between October and December 2021. Inclusion criteria were patients over 18 years positive for COVID-19 in upper respiratory tract samples using real-time PCR test. Exclusion criteria were pregnant women, ageyears, and patients with incomplete records at admission. Results. The mortality rate was assessed in correlation with the most prevalent comorbidities such as diabetes, cardiovascular diseases, hypertension, chronic kidney disease, and chronic pulmonary diseases, either alone or associated. During hospitalization, an aggravated health condition was noticed for 71 patients (40.11%). Among them, 47 patients were transferred to the intensive care unit (66.20%) due to severe respiratory failure, aggravation of associated diabetes and/or other associated comorbidities. Ventilation support was necessary in 122 cases (68.63%). The average survival time was 8.66 days. In conclusion, we found that the most prevalent comorbidities were cardiovascular diseases, being the major risk factor for mortality or aggravation after hospitalization. Its association with diabetes caused a risk of death 2.1 times higher than in patients without comorbidities. Based on Kaplan–Meier survival analysis, we found that the in-hospital survival rate was significantly higher in females compared to males (50.52% vs 33.75%).
