Introduction: Obstructive sleep apnea (OSA) is a disease that decreases the quality of sleep and increases morbidity. Positive airway pressure (PAP) treatment is known to be the most effective method in OSA. Since July 2018, the national health insurance has been applied to PAP, reducing the financial burden on patients. This study aims to examine the adherence of patients prescribed PAP before and after insurance and to analyze factors that have influence on the adherence.

Methods: As a retrospective study, the adherence of the group of patients who were prescribed PAP from July 2016 to June 2018, and the group from July 2018 to September 2020 after the insurance coverage was compared. A patient’s underlying disease, Epworth sleepiness scale (ESS) and polysomnography results, as well as PAP adherence for the 1st, 3rd, 6th, 9th month were examined.

Results: The patients were divided into pre- (pre-I, n=26) and post-national health insurance (post-I, n=168) groups. Mean age of each group was 47.3 (pre-I) vs. 49.6 (post-I) (p=0.240) and male:female ratio was 21:5 vs. 142:26 (p=0.158). ESS was 10.0 vs. 9.1 and apnea-hypopnea index was 52.8 vs. 50.5. Adherence of each month for pre-I and post-I was 73% vs. 67%, 71% vs. 64%, 53% vs. 46%, 44% vs. 41%. Patients with cerebrovascular accident were more adherent to PAP (p=0.000).

Conclusions: The adherence of PAP therapy might not be related with the insurance coverage for OSA patients.
