Lee DY, Cho J, You SC, et al. - In elderly coronavirus disease 2019 (COVID-19) patients with and without mental disorders in South Korea, researchers examined clinical features and if these features correlate with underlying mental disorders causing mortality in this population-based comparative cohort study. Using the national claims database, they identified 814 elderly COVID-19 patients (255 [31.3%] with mental disorder and 559 [68.7%] with nonmental disorder). After propensity score stratification, 781 patients were included in each group (236 [30.2%] with mental disorder and 545 [69.8%] with nonmental disorder). After comparing the two groups, results suggest that the mental disorder group had more risk factors for COVID-19. Per findings, there might be a higher risk of COVID-19 among elderly patients with comorbid conditions and those taking psychiatric medications. Patients with mental disorders were more likely to be older, taking antithrombotic agents, and have diabetes, hypertension, chronic obstructive lung disease, and urinary tract infections vs those without mental disorders.
