A Multicenter Cross-Sectional Study on the COVID-19 Patients Admitted to Hospitals in Qazvin, Iran

Abstract

Background: Coronavirus disease 2019 (COVID-19) is a global pandemic that has spread worldwide. The high rates of morbidity and mortality associated with the disease are notable, causing significant socioeconomic damage in many parts of the world. Objectives: This study investigates the epidemiological status of COVID-19 in patients admitted to 15 hospitals between 2020 and 2021. Methods: In this multicenter cross-sectional study, we analyzed 18,653 patients with COVID-19 who were treated in hospitals. Demographic characteristics, symptoms, and comorbidities were also assessed. Additionally, the duration of hospitalization and the outcomes of the disease (recovery or death) were recorded. Data were extracted from the National Registry System of the Medical Care Monitoring Center (MCMC) and analyzed using SPSS software version 18. Chi-square and Fisher’s exact tests were used to analyze categorical data. A P-value of less than 0.05 was considered statistically significant. Results: From February 4, 2020, to February 3, 2021, 18,653 patients were hospitalized in hospitals in Qazvin province with COVID-19 symptoms. A total of 2,678 patients died. Approximately 14.7% (2,614) of the patients required intubation, and 9.2% (1,635) required oxygen therapy. Cardiovascular diseases, hypertension, and diabetes mellitus were the most common comorbidities. Conclusions: The present study indicates that advanced age, underlying diseases, and intubation are associated with an increased risk of death in patients with COVID-19. Given the various strains of coronavirus, epidemiological studies are essential for the prevention, control, and understanding of this disease.
