Racial disparity in adherence to positive airway pressure among US veterans.

Purpose: Despite advances in continuous positive airway pressure (CPAP) technology, compliance with CPAP therapy remains suboptimal. Studies conducted since the advent of objective CPAP recording have noted that African Americans (AA) may use CPAP less than Whites. We sought to confirm this finding among a large sample of veterans and examine effect modifiers of the differential usage.

Correlates of a prescription for Bilevel positive airway pressure for treatment of obstructive sleep apnea among veterans.

Introduction: The acceptance of portable home-based polysomnography together with auto-titrating CPAP has bypassed the need for a laboratory polysomnography. Since bilevel airway pressure (BPAP) is titrated in the sleep lab, patients diagnosed using portable home-based polysomnography may not have the opportunity to receive BPAP. It is unknown whether the patients who would have ordinarily received a BPAP would benefit from it.
