Predictors for short-term and long-term APAP compliance

Positive airway pressure (PAP) is considered a standard treatment for Obstructive sleep apnea (OSA), but there are compliance issues. As compliance to PAP tends to decrease with time, it is necessary to consider reasons affecting compliance at each period. Therefore, this study aimed to define factors affecting short-term and long-term compliance in PAP.One hundred eighty-seven OSA patients who started PAP treatment between July 2018 to March 2020 were included. Acceptance and compliance rates were monitored. Demographics, Polysomnography (PSG) profiles, cephalometric data, and physical examination results were analyzed to identify factors predictive of PAP compliance at short-term (3 months) and long-term (12 months) periods.The acceptance rate of PAP was 92.5%. Compliance at 3-months and 12-months was 79.1% and 51.3%, respectively. Higher apnea-hypopnea index (AHI) (OR 1.018, P = .049) and older age (OR 1.032, P = .039) were predictive factors of good automatic PAP (APAP) compliance at 3 months. However, long-term compliance was affected by CT90 (OR 1.032, P = .011) and baseline subjective symptom scores such as nasal obstruction (OR 0.819, P = .038) and awakening (OR 0.796, P = .045).In PAP use, indicators of OSA severity such as AHI affect short-term compliance. On the other hand, MPH and subjective symptoms such as nasal obstruction and awakening can affect long-term compliance.
