Adherence to Positive Airway Pressure therapy as Severity of Adult Obstructive Sleep Apnea / 대한이비인후과학회지

ABSTRACT

Background and Objectives@#The aim of this study was to compare adherence to positive airway pressure (PAP) therapy in patients with obstructive sleep apnea (OSA) of different severity.Subjects and Method We conducted a retrospective study including 270 adult OSA patients who used a PAP device for at least 3 months. We assessed the percentage of days on which the device was used, the percentage of days on which the device was used for ≥4 h, and the average duration of PAP device usage at 12 weeks of PAP therapy. We also evaluated adequate adherence to PAP therapy using a PAP device for ≥4 h/day and during ≥70% of nights. @*Results@#The percentage of days on which a PAP device used did not differ significantly according to OSA severity (median [Q1-Q3]; mild 91.40% [81.25%-97.65%], moderate 94.50% [86.90%-100%], severe 95.90% [88.10%-100%], p=0.268). We also found that the percentage of days on which a PAP device was used during sleep for ≥4 h was not significantly different in patients with different OSA severity (median [Q1-Q3], mild 76.20% [69.70%-89.90%], moderate 89.30% [67.65%-95.70%], severe 85.70% [75.85%-95.45%], p=0.097). The percentage of patients with adequate PAP adherence did not differ significantly according to OSA severity (mild 74.2%, moderate 72.1%, severe 83.0%, p=0.084). Moreover, the mean duration (minutes) of PAP device usage during sleep did not differ significantly according to OSA severity in the mild, moderate, and severe OSA groups (mean±standard deviation, mild 348.03± 47.78 min, moderate 358.58±85.22 min, severe 363.79±57.21 min, p=0.440). @*Conclusion@#Adherence to PAP therapy did not differ significantly according to OSA severity. Therefore, it is necessary to continuously expand and maintain the insurance for health promotion in OSA patient in South Korea.
