Multicenter Study
Prevalence of residual excessive sleepiness in CPAP-treated sleep apnoea patients: the French multicentre study.
The percentage of compliant continuous positive airway pressure (CPAP)-treated apnoeic patients that continue to experience residual excessive sleepiness (RES) is unknown. RES was defined by an Epworth Sleepiness Scale (ESS) score of >or=11. In total, 502 patients from 37 French sleep centres using CPAP >3 h night(-1) attending their 1-yr follow-up visit were eligible. ⋯ The relative risk of having RES was 5.3 (95% CI 1.6-22.1), when ESS before treatment was >or=11. Scores of emotional and energy Nottingham Health Profile domains were two times worse in patients with RES. As 230,000 obstructive sleep apnoea patients are currently treated in France by continuous positive airway pressure, more than 13,800 of them might suffer from residual excessive sleepiness.
