Background: Coronavirus disease (COVID-19) is a public health emergency of international concern. The aim of this study was to determine clinical features and outcomes of patients with COVID-19.

Methods: This study was a retrospective cohort that included all patients with COVID-19 who were hospitalized in the Shahid Sayad Shirazi and 5 Azar hospitals in Gorgan (northeastern Iran) from April to September 2020. Overall, information from 345 eligible patients was recorded. Data were described using descriptive statistics. Data analysis was carried out in SPSS software (version 24).

Results: The mean age of patients with COVID-19 was 55.94 years (standard deviation=17.28). The majority of patients were women (51.9%). Disease outcomes were reported as recovery, death, and unknown for 77.1%, 2.6%, and 20.3% of the patients, respectively. The most prevalent underlying conditions were hypertension (29.3%), type 2 diabetes (16.8%), and heart disease (8.4%). The most common symptoms were shortness of breath (55.4%), weakness and fatigue (44.3%), and cough (39.7%). Moreover, the most common computed tomography scan findings were ground glass opacities (32.75%), consolidation (26.67%), and thickening of the pulmonary interstitial structures (13.62%).

Conclusion: Studying the duration of hospitalization and its related factors can provide a better understanding of COVID-19’s impact on medical interventions as well as hospital capacities to deal with the rising number of COVID-19 patients. Clinical features, laboratory findings, and their relationship with the outcome of patients with COVID-19 can be crucial for early diagnosis and management of the disease. In addition, due to the importance of optimal use of limited health facilities, optimizing patient classification and creating predictive tools for a better treatment outcome seem essential.
