The aim of this study was to compare the risk of undiagnosed sleep disorders among medical patients with COPD compared with those without COPD.
Hospitalized medical ward patients without a known sleep disorder were screened, using validated questionnaires, for sleep disorders, such as obstructive sleep apnea and insomnia. Daily sleep duration and efficiency in the hospital were measured via wrist actigraphy.
572 patients completed questionnaires and underwent wrist actigraphy. On admission, patients with COPD had a greater adjusted risk of obstructive sleep apnea and clinically significant insomnia; no differences were observed for sleep quality or excess sleepiness on admission. After adjustment, compared with patients without COPD, patients with COPD averaged 34 fewer minutes of nightly sleep, as well as 22.5% lower odds of normal sleep efficiency while in the hospital. No statistically significant differences were observed for in-hospital sleep quality, soundness, or ease of falling asleep.
This study concluded that among hospitalized patients in medical wards, those with COPD have a higher risk of OSA and insomnia and worse in-hospital sleep quality and quantity compared with those without COPD.
