Obstructive Sleep Apnea Clinical Trial
Official title:
Validation of Questionnaires to Identify Chinese Patients at Risk for Obstructive Sleep Apnea
The purpose of this study is to validate the Berlin questionnaire and STOP-BANG (snore, tired, obstruction, pressure, body mass index (BMI), age, neck, gender) as effective screening tools for Chinese subjects who are suspected to have obstructive sleep apnea (OSA).
Obstructive sleep apnea (OSA) is a common sleep related breathing disorder associated with
excessive daytime sleepiness and cardiovascular disease. It is prevalent in both western
(4-26%) and eastern countries (4-19%). In recent studies, it has been estimated that at
least 70-80% of middle aged individuals with sleep apnea are undiagnosed and untreated. The
prevalence of undiagnosed OSA subjects within the community suggests the need for a greater
awareness and a high index of suspicion of this disease entity as well as its associated
short- and long-term comorbidities.
A reliable and easy-to-use screening questionnaire is required for efficient prediction of
OSA and treatment arrangement. It would be helpful to prioritize patients who require sleep
study according to the probability of suffering from sleep apnea. It reduces the use of
sleep study for those with low probability of having OSA, but giving treatment to those who
are with more severe OSA first. Meanwhile, it enhances the cost effective management of
disease especially with limited resources in our society.
