Abstract

IMPORTANCE The association of positive airway pressure (PAP) with reduced mortality in patients with obstructive sleep apnea (OSA) remains uncertain.

OBJECTIVE To investigate the association between PAP prescription and mortality.

DESIGN, SETTING, AND PARTICIPANTS 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.

EXPOSURES Self-reported use of PAP.

MAIN OUTCOMES AND MEASURES All-cause mortality.

RESULTS 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.

CONCLUSIONS AND RELEVANCE 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.
