Adherence to Positive Airway Pressure Therapy in Patients With Obstructive Sleep Apnea

Adherence to either continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP) therapy in patients with obstructive sleep apnea syndrome (OSAS) represents a real challenge to sleep medicine physicians. Many risk factors/predictors for nonadherence exist, and usually, it is multifactorial. Long-term nonadherence with CPAP therapy has been associated with the use of CPAP for <4 hours/night during early treatment, moderate to severe obstructive sleep apnea (OSA), poor self-efficacy, and unsupportive bed partner. The American Academy of Sleep Medicine (AASM) recommends follow-up of patients with OSA within the first two weeks of CPAP use to optimize adherence. Measures to improve adherence to positive airway pressure (PAP) therapy go through an integrated approach that involves behavioral therapy and prompt management of side effects. Pharmacologic therapy in the form of a sedative-hypnotic sleep aid has a minor role in managing nonadherence to CPAP based on the greater risk of side effects. This article will briefly discuss the risk factors and management of nonadherence to PAP therapy in patients with OSAS.
