Abstract

BACKGROUND: Severe acute respiratory syndrome coronavirus‑2 (SARS‑CoV‑2) causes COVID‑19. 
On March 11, 2020, the WHO declared it a pandemic. SARS‑CoV‑2 indicates that it poses a 
significant threat to public health and global economy. The aim of the study was to determine (a) 
patient characteristics, (b) demographic characteristics, (c) comorbidities, diagnostic methods used, 
treatment, and outcomes, and (d) mortality rates of patients.
MATERIALS AND METHODS: This retrospective cohort study included 352 hospitalized adult 
patients from Baskent University Hospital in Ankara who were confirmed cases of COVID‑19 between 
March 2020 and March 2021. SPSS v. 14.0 was used for statistical analysis.
RESULTS: Out of 352 patients, 55 died (males: 37, females: 18), while 297 survived (males: 162, females: 
135). The most common comorbidities were hypertension (HT), diabetes mellitus (DM), coronary artery 
disease (CAD), cancer, Vitamin D deficiency, and chronic obstructive pulmonary disease. Comorbidities 
associated with mortality rate were obesity (33%) (P = 0.118), Vitamin D deficiency (28%) (P = 0.009), 
DM (25%) (P = 0.004), CAD (21.2%) (P = 0.142), cancer (20.9%) (P = 0.084), and HT (16.6%) (P = 0.90). 
Normal ward admission resulted in death in 67.3% and survival in 93.9% (P = 0.001), intensive care 
unit (ICU) admission resulted in death in 69.1% and survival in 18.5% (P = 0.001), and oxygen therapy 
was used in 80% death and survival in 39.4% (P = 0.001).
CONCLUSIONS: Our study shows that male gender, advanced age, and presence of comorbidities 
in COVID 19 patients are at higher risk for severe disease, ICU admission, and death. We emphasize 
that morbidity and mortality can be reduced by early and comprehensive identification of risk factors 
and the warning systems that will meet the ICU needs of these patients.
