Goldstein CA, Rizvydeen M, Conroy DA, et al. - Since obstructive sleep apnea (OSA) and other sleep disorders overlap with co-morbidities correlated with poor outcomes related to SARS-CoV-2 infection, researchers sought to identify the prevalence of pre-existing sleep disorders and their correlations with outcomes related to severe COVID-19 illness. Participants in the study were patients with SARS-CoV-2 infection (n = 572) admitted to the University of Michigan Hospital System. After adjusting for age, gender, BMI, and race, no significant link was evident between sleep disorders diagnoses or indices of sleep-disordered breathing severity and outcomes. This is the first study determining the prevalence of OSA and other sleep disorders in a well-characterized cohort of individuals hospitalized for COVID-19. Once hospitalized, a significant contribution of sleep disorders to outcomes was not identified. Future assessments should therefore focus on earlier outcomes, such as infection or clinical manifestations following exposure to SARS-CoV-2.
