- Abstract
<bold>Importance: </bold>The association of positive airway pressure (PAP) with reduced mortality in patients with obstructive sleep apnea (OSA) remains uncertain.<bold>Objective: </bold>To investigate the association between PAP prescription and mortality.<bold>Design, Setting, and Participants: </bold>This multicenter, population-based cohort study evaluated data from the Sleep Heart Health Study (SHHS), a long-term observational cohort study that included participants between 1995 and 1998, with a mean follow-up of 11.1 years. Analyses were performed in September 2018. Within the SHHS, we compared patients with obesity and severe OSA with (n = 81) and without (n = 311) prescription of PAP therapy, after matching patients from each group by age, sex, and apnea-hypopnea index.<bold>Exposures: </bold>Self-reported use of PAP.<bold>Main Outcomes and Measures: </bold>All-cause mortality.<bold>Results: </bold>Of 392 study participants, 316 (80.6%) were men, and mean (SD) age was 63.1 (11.0) years. Ninety-six deaths occurred; 12 among the prescribed-PAP group and 84 among the nonprescribed-PAP group, yielding crude incidence rates of 12.8 vs 24.7 deaths per 1000 person-years. In Cox multivariate analysis, the hazard ratio (HR) of all-cause mortality for prescribed PAP therapy was 0.38 (95% CI, 0.18-0.81). After propensity matching, the HR of all-cause mortality for prescribed PAP therapy was 0.58 (95% CI, 0.35-0.96). According to survival curves, the difference in mortality appears 6 to 7 years after initiation of PAP therapy.<bold>Conclusions and Relevance: </bold>Positive airway pressure prescription is associated with reduced all-cause mortality, and this association appears several years after PAP initiation. If replicated, these findings may have strong clinical implications.
