CPAP compliance affects short-term and long-term clinical outcomes. Data on factors associated with adherence to CPAP has been limited. This study aimed to determine the prevalence of CPAP adherence and factors affecting non-adherence in OSA patients.</p>
<p><strong>Methods:</strong> A cross-sectional study was conducted in OSA patients aged 18 years or older with CPAP treatment. Demographics, clinical characteristics, and CPAP adherence (usage ≥ 4 hours/night for ≥ 70% of nights) at 2 weeks, 4 weeks, 3 months, and 6 months were recorded. Patients were divided into 2 groups: adherence and non-adherence.</p>
<p><strong>Results:</strong> In total, 210 patients (61% male) participated in this study. Mean age was 53.5 ± 14.8 years. Body mass index was 30.7 ± 6.9 kg/m<sup>2</sup>. Comorbidities included hypertension (63%), heart disease (18%), and cerebrovascular disease (5%). Polysomnographic data showed apnea- hypopnea index was 48.9 ± 32.0 events/hour, nadir saturation was 79.3 ± 11.4% and 3% oxygen desaturation index was 14.3 ± 16.9 events/hour. Severe OSA was 68%. The proportion of CPAP adherence in 2 weeks, 4 weeks, 3 months, and 6 months was 59.1%, 60.0%, 57.6%, and 56.8%, respectively. The factors associated with CPAP non-adherence were CPAP mask off at night, irregular sleep time, no time to use CPAP, dry month, and doctor follow-up schedule more than 6 months. Moreover, when patients had good compliance at 2 weeks, they had significantly good compliance at 4 weeks, 3 months, and 6 months.</p>
<p><strong>Conclusions:</strong> Only about a half of OSA patients had a good adherence to CPAP. There were many factors affecting CPAP adherence. When patients had a good compliance in a short-term period, they were likely to have good compliance in a long-term period.</p>}, number={-}, journal={Asian Medical Journal and Alternative Medicine}, author={Saiphoklang, Narongkorn and Leelasittikul, Kanyada and Pugongchai, Apiwat and Suksupakit, Shayada and Sattaratpaijit, Nithita}, year={2022}, month={Aug.}, pages={S119} }
