Background and Objective:Hospital readmissions are common and expensive. Identifying the patients who are at high risk of readmission can decrease readmission. Hence, in the present study, the clinical characteristics, biomarker results, and Computed Tomography (CT) criteria of all the readmitted patients were assessed. Materials and Methods:Data of 98 readmitted patients to the Baqiyatallah Hospital in Tehran reviewed from December 22, 2019 through June 20, 2020. We classified the readmitted patients into three groups: patients (1) without COVID-19 symptoms, (2) with suspected COVID-19, and (3) with confirmed COVID-19 infection. Results:Our data revealed that the frequency of gender was significantly different between groups (with higher frequency for men). The duration between two admissions were significantly low in the confirmed COVID-19 group. Ischemic heart disease, hypertension, and diabetes mellitus were more common in confirmed COVID-19 group. High levels of CRP, and ESR detected in the confirmed COVID-19 group. During the first admission, the count of WBC was significantly lower in the confirmed COVID-19 group, the RBC count and hemoglobin level was significantly higher in both the first and second admission in the confirmed COVID-19 group. Most of the patient’s had bilateral lung lesions and ground glass opacities (GGO) in their CT Scans in the second admission. Conclusion:Our data suggested that the older men and ischemic heart disease, hypertension and diabetes mellitus had a high risk of hospital readmission in COVID-19. The confirmed COVID-19 group showed a shorten time to be readmitted. Keywords:Patient readmission,COVID-19,Risk factors,Comorbidity |
