    Study Objectives: Sleep-disordered breathing (SDB) has been implicated as a risk factor for the development of several adverse cardiovascular outcomes, but can be mitigated with positive airway pressure therapy (PAP). The nonadherence of patients with SDB on PAP in the outpatient setting ranges from 29% to 84%. However, adherence of PAP in patients with congestive heart failure (CHF) admitted for decompensated CHF and in whom SDB has been diagnosed in the hospital setting is not known. We hypothesized that despite a diagnosis in the hospital, the compliance of these patients with PAP therapy would not be different from the well-established adherence in patients with a diagnosis and treatment in the outpatient setting. Methods: The study was a retrospective analysis of patients admitted to an academic tertiary care hospital between March 2013 and February 2014. Patients presenting with decompensated CHF were screened and high-risk patients were started on PAP empirically and advised to undergo a postdischarge polysomnogram. Compliance of the patients with PAP was tracked for over 12 mo. Data from a similar outpatient group who underwent polysomnography during the study period were also reviewed. Results: Ninety-one patients underwent polysomnograhy postdischarge. Of the 91 patients, 81 patients agreed to PAP therapy. One patient was excluded as data were missing. The adherence at 3, 6, and 12 mo was 52%, 37%, and 27%, which was not significantly different than an outpatient control group. There was a trend for those with CHF plus SDB and compliant with PAP to have a higher probability of survival compared to those who were noncompliant (p = 0.07). Conclusions: Adherence of patients to PAP therapy in whom a SDB diagnosis is made during acute hospitalization for heart failure is comparable to patients in the ambulatory setting. Adherence in first 3 mo is a predictive marker for improved survival trend.
