Many sufferers hospitalized for COVID-19 are identified with a sleep disorder

Sleep disorders, including obstructive sleep apnea (OSA) and insomnia, are common in patients hospitalized for COVID-19, but these disorders appear not to be to mortality or serious consequences associated with the novel coronavirus, according to study results published in the Journal to contribute to clinical sleep medicine.

The study included 572 adult patients hospitalized for COVID-19 within the University of Michigan hospital system. The study researchers evaluated electronic medical records to determine the prevalence of sleep disorders. Diagnostic sleep studies, conducted in 13% of the study population, were conducted either in a laboratory or off-center using Type 3 portable monitors.

The study researchers performed an analysis to assess the association of insomnia with the need for mechanical ventilation, the need for vasopressor treatment, and death.

Approximately 19.8% (n = 113) of the 572 patients hospitalized for COVID-19 had OSA. Only 0.7% (n = 4) of the total cohort suffered from central sleep apnea, while 11.0% (n = 63) suffered from insomnia. The results showed hypoventilation in 0.9% (n = 5) of hospitalized patients and Restless Syndrome or Periodic Limb Movement Disorder (RLS / PLMD) in 3.9% (n = 22) of patients.

Although the overall prevalence of sleep disorders in the study population was high, the study researchers found no significant association between specific diagnoses of sleep disorders or indices for sleep- breathing disorders with disease severity and the results in an analysis based on , gender, body mass index , and races.

The presence of OSA and insomnia was associated with an increased risk of death (OR 1.83; 95% CI 0.89–3.75) and a need for vasopressors (OR 1.86; 95% CI 0.98–3, 56) connected. There was no significant association between the presence of OSA, insomnia, or RLS / PLMD and the use of mechanical ventilation, the need for vasopressors, the length of stay, or death.

Limitations of this study included reliance on diagnostic codes to identify sleep disorders and the lack of available data on treatments for sleep disorders in the cohort.

The study’s researchers concluded that “sleep disorders may be relevant to long-term cardiac outcomes because of their contribution to cardiovascular health” in patients with COVID-19, but it “remains an open question whether new sleep disorders will be among these long-term consequences “. who are recovering from severe COVID-19. “
