Factors Associated With Readmission to the Emergency Department in a Cohort of COVID-19 Hospitalized Patients

This study examined factors associated with readmission to the Emergency Department (ED) in a cohort of 441 COVID-19 patients discharged from San Cecilio University Hospital in Spain during the first wave of the pandemic. The study found that 20.8% of patients were readmitted to the ED within 6 months of discharge. Persistent symptoms were common, with respiratory, systemic, and neurological symptoms being the most prevalent. Key factors linked to readmission included polymedication, living in a care home, and symptoms such as thoracic pain, general malaise, and hematological issues. Thoracic pain and general malaise were significant risk factors after multivariate analysis. These findings suggested that certain symptoms and patient profiles could help optimize follow-up strategies, though further studies in different regions were recommended to validate these results.
