ABSTRACT

PURPOSE: To evaluate adherence to continuous positive airway pressure (CPAP) treatment in elderly patients newly diagnosed with obstructive sleep apnea syndrome (OSAS).

METHODS: Consecutive patients ≥ 70 years attending one of the participating centers, requiring CPAP treatment and agreeing to participate, were included. Mean hours of CPAP during the first 5 months of treatment defined adherence as CPAP ≥ 4 h/day on 70% of nights over a 30-day period.

RESULTS: From January 2014 to April 2019, 262 patients aged between 76.7 and 87.7 years (mean age, 82.6 years) were included and fully evaluated; 224 (85.5%) were adherent. Mean adherence time was 6.9 h in adherent patients, vs 2 h in non-adherent patients (p < 0.0001). Compared to non-adherent patients, adherent patients tended to have higher baseline AHI without reaching statistical significance (44.7 vs 39.5, p = 0.0913). They less frequently presented with dementia (3.7% vs 21.6%, p < 0.0001). The somnolence (ODSI and Epworth), nocturia, and depression (QD2A) scores of adherent patients improved significantly from baseline to the fifth month: ODSI decreased from 7 to 3.7 (p < 0.0001), Epworth from 8.7 to 6.2 (p < 0.0001), nocturia from 6.6 to 4.1 (p = 0.0015), and QD2A from 3.7 to 3 (p = 0.0025). Many more patients in the non-adherent group used nasal plugs than in the adherent group (14.7% vs 2.1%, p = 0.0006).

CONCLUSION: The present real-world study showed the ability of newly diagnosed elderly adults (including the very old) to adhere to CPAP therapy and the benefit of 5 months’ well-conducted CPAP treatment.
