Abstract
PURPOSE: Obstructive sleep apnea (OSA) is associated with a range of neurocognitive and cardiovascular complications, leading to a compromised quality of life. Continuous positive airway pressure (CPAP) is the gold standard therapeutic intervention for this disorder, yet patient compliance remains essential to its success. This study aimed at identifying the determinants of short-term and long-term CPAP adherence in a group of Lebanese patients. METHODS: This cross-sectional study, conducted at the Sleep Center of Hôtel-Dieu de France hospital in Lebanon, included patients diagnosed with OSA and treated with CPAP for at least one night between June 2008 and January 2015. Adherence was assessed based on patients' self-report. RESULTS: The study enrolled 138 patients. Adherence rate was 70.3 % at 6 months and around 50 % after 5 years. Cox models showed that use of nasal masks (HR 0.48, p = 0.048) and higher oxygen desaturation index at baseline (HR 0.98 p = 0.048) were associated with a better short-term CPAP adherence. Patients who bought their devices (HR 0.18, p < 0.001), those who were frequently contacted by the CPAP provider (HR 0.85, p 0.024), and those who reported improvement on treatment (HR 0.36, p < 0.001) were significantly more likely to remain adherent on the long term. Conversely, individuals on a diet plan tended to interrupt the treatment earlier (HR 4.85, p 0.039). CONCLUSION: The present findings should be further explored in order to tailor interventions to the specific needs of different patient profiles and secure an improved CPAP adherence.
