Are symptoms of obstructive sleep apnoea related to good continuous positive airway pressure compliance?

Obstructive sleep apnoea (OSA) is a common disease that can be treated with continuous positive airway pressure (CPAP). CPAP tolerance may be associated with its compliance. Even though there are several predictors for good CPAP compliance, there are limited data available on the correlation between CPAP compliance and OSA symptoms. This study aimed to evaluate this correlation. We conducted a cross-sectional study and enrolled adult patients diagnosed with OSA through polysomnography who had experience using a CPAP machine. A self-report questionnaire was used to evaluate CPAP compliance and study variables. Predictors of CPAP compliance were analysed using stepwise multivariate logistic regression analysis. There were 68 patients with OSA who completed the questionnaire during the study period. Of those, 14 (20.59%) exhibited good CPAP compliance. Only fatigue as a symptom was an independent factor associated with good CPAP compliance, with an adjusted odds ratio of 5.380 (95% CI 1.274-22.719). In conclusion, fatigue was the only symptom associated with good CPAP compliance in patients with OSA.
