A biphasic effect of age on CPAP adherence: a cross-sectional study of 26,343 patients

Abstract

Abstract Background As the prevalence of OSA increases in older patients, the proportion of elderly patients treated with CPAP is expected to become even higher. We studied CPAP-adherence in a real-life cohort involving a large population of elderly patients with OSA. Methods eQUALISAS is a cross-sectional study of CPAP treated OSA patients for at least 4 months who received remote monitoring during 2021. CPAP adherence, device-reported residual AHI (AHICPAP) and 95th percentile non-intentional leaks were software collected during January 2021. Age and sex were also collected. Results Data from 26,343 patients including 1656 patients aged [80–85] years and 639 patients aged ≥ 85 years were analysed. Median CPAP adherence increases from 6.3 h ( 0.05). Conclusion This study demonstrates that adherence gradually increases with age until 80 years. The proportion of non-adherent patients grows with age after 80 years old. No significative relationship was found between adherence after 80 years old and gender, leaks and AHICPAP. Trial registration: The study is registered on Health Data Hub platform (No. F20220715144543).
