Brief summary

This observational survey with retrospective follow-up is designed to study the daytime sleepiness based on Epworth Sleepiness Scale a good way or not to assess Taiwanese with suspected obstructive sleep apnea.

Detailed description

Daytime sleepiness (DS) is a complicated clinical problem, often indicating a serious underlying physiological abnormality and associated with higher prevalence of comorbid conditions such as diabetes, myocardial infarction, and stroke. Daytime sleepiness is also the cardinal symptoms of obstructive sleep apnea. How to identify the high risks patients with obstructive sleep apnea for further polysomnography is a difficult problem for doctors in out-patient department. Different methods have been proposed for measuring sleepiness and the Epworth sleepiness scale (ESS) is the measure of sleepiness most commonly used in sleep research and clinical settings. However, whether Epworth sleepiness scale is a good tool with high predictive value of obstructive sleep apnea is not evaluated in the population of Taiwanese. This observational study is set up to document these practices.

Design outcomes

Primary

Measure	Time frame	Description
Correlation between Epworth sleepiness scale and the severity of obstructive sleep apnea	baseline (The Epworth sleepiness scale was completed just before the polysomnography)	use analysis to calculate the correlation
The specificity and sensitivity of Epworth sleepiness scale for obstructive sleep apnea	Baseline (The Epworth sleepiness scale was completed just before the polysomnography)	use receiver operating characteristic curve (cut point of 10) to calculate the specificity and sensitivity

Secondary

Measure	Time frame
Questionnaire: If there are some specific symptoms as a tool with better sensitivity or specificity than Epworth sleepiness scale for obstructive sleep apnea	Baseline
