AbstractObstructive sleep apnea (OSA) is a chronic disease treated effectively with the use of continuous positive airway pressure (CPAP) therapy. Patient adherence to prescribed CPAP is variable, however, leaving the undertreated OSA patient at risk of development or worsening of comorbid medical conditions, including hypertension and cardiovascular disease. The severity of disease and the presence of daytime sleepiness appear to have some predictive quality for subsequent adherence, though a search for consistent predictive factors related to CPAP adherence has proven elusive. Other influences, such as sex, age, socioeconomic status, and personality traits are less robust predictors. The use of sophisticated therapy modalities such as auto-titration or bi-level PAP units has been shown to improve adherence in certain subsets of OSA patients. Adverse effects such as nasal congestion, dry mouth, or skin irritation occur in approximately 50% of CPAP users, and addressing these adverse effects may improve adherence in some patients. More encouraging, studies on the use of intensive patient education and behavioral interventions have shown more positive effects on adherence, leading to the conclusion that improvement in patient adherence to CPAP therapy requires a multi-layered approach, using combined technological, behavioral, and adverse-effect interventions.
