COVID-19 has been introduced by the World Health Organization as a health emergency worldwide. Up to 9% of the patients with COVID-19 may be readmitted by 2 months after discharge. This study aimed to estimate the readmission rate and identify main risk factors for readmission in these patients. In this prospective study, 416 discharged COVID patients followed up with a minimum 1 month and the readmission rate was recorded. Evaluated characteristics included time of readmission, age and sex, main symptoms of disease, result of computed tomography scan, reverse transcription polymerase chain reaction test and treatment modalities.
Regarding readmission, 51 patients of 416 discharged patients, was readmitted during the study period. The rate of readmission for 30 and 60 days after discharge was 7.6% and 8.1%, respectively. The median age of the readmitted patients was 67 years (IQR: 53-78). About 65% of readmitted patients had underlying disease. The most significant factor in readmission rate was related to the site of lung involvement (OR > 4). Age over 60 years, underlying disease especially diabetes (OR = 3.43), high creatinine level (≥ to 1.2 mg/dl) (OR = 2.15) were the most important predictors of readmission.
世界卫生组织已将 COVID-19 宣布为全球卫生紧急事件。COVID-19 患者中有高达 9%的患者可能在出院后 2 个月内再次入院。本研究旨在评估这些患者的再入院率并确定再入院的主要危险因素。在这项前瞻性研究中，对 416 例出院的 COVID 患者进行了至少 1 个月的随访，并记录了再入院率。评估的特征包括再入院时间、年龄和性别、疾病主要症状、计算机断层扫描结果、逆转录聚合酶链反应检测和治疗方式。
在研究期间，416 例出院患者中有 51 例再次入院。出院后 30 天和 60 天的再入院率分别为 7.6%和 8.1%。再入院患者的中位年龄为 67 岁（IQR：53-78）。约 65%的再入院患者有基础疾病。再入院率的最重要因素与肺部受累部位有关（OR>4）。年龄超过 60 岁、基础疾病尤其是糖尿病（OR=3.43）、肌酐水平升高（≥1.2mg/dl）（OR=2.15）是再入院的最重要预测因素。
