Abstract
BackgroundObstructive sleep apnea (OSA) is associated with increased risks of respiratory complications following surgery, however its relationship to the outcomes of hospitalized medical patients is unknown.MethodsWe carried out a retrospective cohort study of patients with pneumonia at 347 US hospitals. We compared the characteristics, treatment and risk of complications and mortality among patients with and without a diagnosis of OSA while adjusting for other patient and hospital factors.ResultsOf the 250,907 patients studied, 15,569 (6.2%) had a diagnosis of OSA. Patients with OSA were younger (63 vs. 72 years), more likely to be male (53% vs. 46%), married (46% vs. 38%), and had a higher prevalence of obesity (38% vs. 6%), chronic pulmonary disease (68% vs. 47%), and heart failure (28% vs. 19%). Patients with OSA were more likely to receive invasive (18.1% vs. 9.3%) and noninvasive (28.8% vs. 6.8%) forms of ventilation upon hospital admission. After multivariable adjustment, OSA was associated with an increased risk of transfer to intensive care (OR 1.54, 95% CI 1.42 - 1.68) and intubation (OR 1.68, 95% CI 1.55 - 1.81) on or after the third hospital day, longer hospital stays (RR 1.14, 95% CI 1.13 - 1.15), and higher costs (RR 1.22, 95% CI 1.21 - 1.23) among survivors but lower mortality (OR 0.90, 95% CI 0.84 - 0.98).ConclusionAmong patients hospitalized for pneumonia, OSA is associated with higher initial rates of mechanical ventilation, increased risk of clinical deterioration and higher resource utilization, yet a modestly lower risk of inpatient mortality.
