Background: Continuous positive airway pressure is the standard treatment forobstructive sleep apnea. However, nonadherence to continuous positive airway pres-sure 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 aims to assess the relationship between the Epworth Sleepiness Scale score and sleep efficiency measured during continuous positive airway pressuretitration polysomnography.

Methods: A retrospective analysis of the medical records of patients with obstructivesleep apnea/hypopnea who had undergone polysomnography for continuous positiveairway 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 scoreand sleep efficiency during polysomnography with continuous positive airway pres-sure showed that patients with excessive daytime sleepiness had higher sleep effi- ciency (mean=82.0%) than patients with normal daytime sleepiness (mean=78.1%) (P = .043).

Conclusion: Patients with excessive daytime sleepiness as measured on the EpworthSleepiness Scale have higher sleep efficiency during continuous positive airway pres- sure titration polysomnography.
