Background and Objective: The numbers of prescriptions for continuous positive airway pressure and automatic positive airway pressure (APAP) machines have increased dramatically since the Korean government changed national health insurance coverage. This study examined adherence to APAP therapy in patients with obstructive sleep apnea who completed the 3-month adaptation period required by the insurance service, and evaluated the factors predictive of good adherence.
Methods: We retrospectively reviewed the medical records of a total of 315 patients who received APAP prescriptions between July 2018 and December 2019. After screening, 189 patients were analyzed. Patients were divided into an adherent (AD) group and a non-adherent (NAD) group based on 9 months’ APAP adherence. Patient demographics, medical history, body mass index and pretreatment polysomnography results, as well as APAP therapy adherence-related variables, the 90th percentile pressure, residual apnea hypopnea status, and type of devices or managers were compared between the two groups.
Results: We found mean usage times, mean pressures, days with ≥ 4 hours of use a day, and 90th percentile pressures differed significantly between the AD and NAD groups. The device-related data at months 1 and 3 and 9 were similar. One type of device performed differently compared to the other devices, but this did not affect adherence.
Conclusions: The mean pressure and 90th percentile pressure were the main determinants of adherence in patients who passed a 3-month compliance assessment conducted by the Korean National Institute of Health. The data on adherence at months 1, 3 and 9 were similar.
