Background : The obstructive sleep apnea (OSA) syndrome is a potentially disabling condition characterized by excessive daytime sleepiness, disruptive snoring, frequent arousals and nocturnal hypoxemia. Self-reported sleep scales and questionnaires are easy to perform and useful method to evaluate the OSA patients. Each sleep scale and questionnaires are reported as a good screening tool for detection of OSA before polysomnographic evaluation. But there were no report about correlation between sleep scale and severity of OSA patients. We studied each sleep scales and questionnaires to confirm the correlation between each sleep questionnaire and the severity of OSA patients.
Methods : Retrospectively consecutive 147 patients who carried out overnight polysomnogram from January 2005 to June 2007 were enrolled. All of the patients data were reviewed their sleep questionnaires which had done before polysomnographic evaluation. Sleep questionnaires were consisted of Epworth Sleepiness Scale (ESS), Stanford Sleepiness Scale (SSS), Insomnia Severity Index (ISI), Berlin questionnaire, Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Index (BDI). OSA patients were divided into 3 groups according to severity by their respiratory disturbance index (RDI) score.
Results : The OSA patients divided into normal, mild, moderate, severe group by their RDI score; Among sleep questionnaires, Berlin questionnaire and BDI had significantly correlated to OSA severity (P<0.05). Between them, Berlin questionnaire showed most positive correlation to OSA severity by RDI score (P<0.005).
Conclusions : Our results revealed that Berlin questionnaire is a most significant scale for prediction of severity of OSA.
