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 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 non-adherence to CPAP plays in outcomes. Analysis included 345 patients (183 adherent and 162 nonadherent).
The researchers found that the adherent group had 215 initial admissions vs 268 index admissions in the non-adherent group.
The nonadherent group had a significantly higher 30-day all-cause readmission rate (adjusted odds ratio [aOR], 3.52; 95% CI, 2.04 to 6.08; P <.001) and 30-day cardiovascular-cause readmission rate (aOR, 2.31; 95% CI, 1.11 to 4.78; P =.024). However, there was no significant difference in 30-day pulmonary-cause readmissions (aOR, 3.66; 95% CI, 0.41 to 32.76; P =.25).
“Non-adherence to CPAP is associated with increased 30-day all-cause and cardiovascular-cause readmission in patients with OSA,” the authors wrote. “Ensuring CPAP adherence is crucial in addressing general and cardiovascular-related health care utilization and morbidity in patients with OSA.”
