The Correlation Between Sleep Efficiency During Continuous Positive Airway Pressure Titration Polysomnography and Epworth Sleepiness Scale Score in Patients with Obstructive Sleep Apnea

Background: Continuous positive airway pressure is the standard treatment for obstructive sleep apnea. However, nonadherence to continuous positive airway pressure use remains a significant limitation that prevents satisfactory results from being achieved. Epworth Sleepiness Scale score and sleep efficiency values may predict adherence. This study aimsto assessthe relationship betweenthe Epworth Sleepiness Scale score and sleep efficiency measured during continuous positive airway pressure titration polysomnography. Methods: A retrospective analysis of the medical records of patients with obstructive sleep apnea/hypopnea who had undergone polysomnography for continuous positive airway pressure titration in an ear, nose, and throat center between January 2014 and August 2017. Results: Assessment of 170 individuals based on the Epworth Sleepiness Scale score and sleep efficiency during polysomnography with continuous positive airway pressure showed that patients with excessive daytime sleepiness had higher sleep efficiency (mean = 82.0%) than patients with normal daytime sleepiness (mean = 78.1%) (P = .043). Conclusion: Patients with excessive daytime sleepiness as measured on the Epworth Sleepiness Scale have higher sleep efficiency during continuous positive airway pressure titration polysomnography.
