|Abstract:||There are numerous risk factors common to Obstructive Sleep Apnoea (OSA) and morbidity and mortality from Coronavirus Disease 2019 (COVID-19).|
The primary aim of this study is to assess the incidence of undiagnosed OSA in patients hospitalised with COVID-19. The secondary aim is to assess the influence of OSA on morbidity and mortality from COVID-19.
This is a prospective, observational study. A consecutive cohort of patients hospitalised with COVID-19 were invited to participate. Patients completed sleep health questionnaires and underwent home sleep testing (HST) using the WatchPAT novel diagnostic device.
Mean age of participants (n=23) was 59.5 years, with 56.5% male and mean body mass index (BMI) of 30.2±4.88. 87% of patients had HST suggestive of OSA, with moderately-severe disease identified in 50%. Patients admitted to ICU had higher mean Apnea-Hypopnea Indices (pAHI) (16.67±11.27) than those on wards (11.79±6.94). Patients with at least moderate OSA (pAHI > 15) had lower mean Epworth scores (5.5±5.64) than those with mild or no OSA (7.46±6.29).
This highlights the prevalence of undiagnosed OSA in this population. Degree of of fatigue and daytime somnolence are independent of OSA severity. OSA is a confounding factor in COVID-19 morbidity.
