Evaluation of Berlin questionnaire validity for sleep apnea risk in sleep clinic populations

ABSTRACT

Introduction: The Berlin questionnaire [BQ] is a common tool to screen for Obstructive Sleep Apnea [OSA] in the general population, but its application in the clinical sleep setting is still challenging. The aim of this study was to determine the specificity and sensitivity of the BQ compared to the apnea-hypopnea index obtained from polysomnography recordings obtained from a sleep clinic in Iran
