Clinical and Epidemiological Characteristics of Hospitalized COVID-19 Patients in Hormozgan, Iran: A Retrospective, Multicenter Study.

Background: To better manage the COVID-19 pandemic, it is necessary to carefully study information about patients with COVID-19. Objective: To report clinical and epidemiological characteristics of COVID-19 patients in southern Iran.
Methods: This cross-sectional retrospective study was conducted based on data extracted from the COVID-19 registry of Hormozgan. Data from patients with confirmed COVID-19 based on CT-scan results or real-time reverse transcriptase-polymerase chain reaction (RT-PCR) results until September 25, 2020, were analyzed for this study (2351 inpatients). We reported demographics, signs and symptoms on admission, comorbidities, and treatments, as well as clinical outcomes, hospital stay, and intensive care unit (ICU) admission.
Results: Most of patients were men (1235/2351; 52.5%) and the most common signs and symptoms included cough (1343/2351; 57.1%), shortness of breath (1224/2351; 52.1%) and fever. The most common comorbidities included hypertension (410/2351 (17.4%), diabetes (343/2351; 14.6%) and chronic cardiac disease (282/2351; 12%). Also, 228 patients (9.7%) were hospitalized in the ICU. The mortality rate was 12.5% (295/2351) among all patients and 64.5% (147/228) in ICU wards, respectively. The number of cases with comorbidities including hypertension, chronic cardiac disease, diabetes, chronic neurological disorders, chronic kidney disease, chronic hematologic disease, malignant neoplasm, moderate or severe liver disease, dementia and fauvism in the ICU was significantly higher than the general wards.
Conclusion: Most characteristics of our patients were similar to those reported in other studies; however, our patients were younger and suffered from a less severe disease. The mortality rate in the ICU was higher than other studies.
