Coronavirus disease 2019 (COVID-19) has become a global health challenge with high transmission and mortality rates. This study aimed to identify prognosis factors of the risk of death among hospitalized patients with COVID-19 in Behbahan City, southwest of Iran.


 In this study, information of 800 patients with COVID-19 admitted to Shahidzadeh Hospital in Behbahan City southwest of Iran from March 20, 2020, to Jan 20, 2021, was investigated. Thereafter, the demographic information, clinical symptoms, vital signs, pharmacotherapy, Laboratory findings and the patients' underlying diseases were extracted and then recorded from their medical records. Cox regression with PH assumption was used to investigate the risk factors of death.


The present study included 800 patients with Covid-19 with a mean age of 57.51 ± 16.83 years old at the time of diagnosis. Accordingly, the studied sample consisted of 447 (55.8%) male and 353 (44.1%) female patients. Based on the Cox regression analysis, age variables (HR=1.04; 95% CI: 1.03-1.05; P<0.001), Cardiovascular Disease (HR=2.46; 95% CI: 1.63- 3.70; P<0.001), and renal failure (HR=2.77; 95% CI: 1.43- 534; P<0.001) were found to be associated with the death risk in patients with COVID-19.


According to the findings of this study, the patient's age at the time of diagnosis, cardiovascular disease, and renal failure were indicated to be the main prognostic factors of high mortality rate in patients with COVID-19. Identifying these risk factors can be helpful in the timely intervention of patients at high risk of death for health care providers.
