HealthDay News — Nonadherence to continuous positive airway pressure (CPAP) is tied to higher rates of hospital readmission for patients with obstructive sleep apnea (OSA), according to a study published in a recent issue of the Journal of Clinical Sleep Medicine.

Kimberly K. Truong, MD, from University of California Irvine, and colleagues retrospectively reviewed medical records of patients with OSA hospitalized at a Veterans Affairs Hospital (2007 to 2015) in order to assess the role nonadherence to CPAP plays in outcomes. Analysis included 345 patients (183 adherent and 162 non-adherent).

The researchers found that the adherent group had 215 initial admissions vs 268 index admissions in the non-adherent group. The non-adherent group had a significantly higher 30-day all-cause readmission rate (adjusted odds ratio [aOR], 3.52; 95%, 2.04-6.08; P <.001) and 30-day cardiovascular-cause readmission rate (aOR, 2.31; 95% CI, 1.11-4.78; P =.024). However, there was no significant difference in 30-day pulmonary-cause readmissions (aOR, 3.66; 95% CI, 0.41-32.76; P =.25).
