PREVALENCE OF SLEEP APNEA IN A PRIMARY CARE CLINIC POPULATION

本研究将调查初级保健诊所人群中睡眠呼吸暂停的患病率，并评估筛查和诊断睡眠呼吸暂停的不同策略的成本效益。该研究还将测量有睡眠呼吸暂停和没有睡眠呼吸暂停的患者在诊断测试前后的健康结果，以确定研究患者在基线时和被告知有睡眠呼吸暂停后的生活质量。我们将使用详细的健康史问卷和脉搏血氧仪筛查初级保健诊所患者的睡眠呼吸暂停，并以标准多导睡眠图作为参考标准评估这些筛查工具的预测准确性。我们将使用详细的健康结果评估问卷对研究对象进行功能评估，以确定生活质量和感知健康问题。我们假设，在护理诊所中看到的轻度至中度睡眠呼吸暂停患者的患病率将高于社区，健康，就业的成年人。我们假设，与没有睡眠呼吸暂停的患者相比，未确诊的睡眠呼吸暂停患者更有可能频繁地就诊。我们还假设，有睡眠呼吸暂停的患者在基线时的生活质量测量得分比没有睡眠呼吸暂停的患者低，而且在被告知诊断后的重复测试中得分也比基线时低。

This study will investigate the prevalence of sleep apnea in a primary care clinic population and evaluate the cost-effectiveness of different strategies for screening and diagnosing sleep apnea. The study will also measure health outcomes in patients with and without sleep apnea, before and after the diagnostic testing to determine the quality of life in the study patients at baseline and after being told of having sleep apnea. We will screen for sleep apnea in primary care clinic patients with a detailed health history questionnaire and pulse oximetry and evaluate the predictive accuracy of these screening tools using standard polysomnography as the reference standard. We will perform functional assessment of the study subjects with a detailed health outcomes assessment questionnaire to determine the quality of life and perceived health problems. We hypothesize that the prevalence of mild to moderate sleep apnea in patients seen in the care clinic setting will be higher than that of a community-based, healthy, employed adults. We hypothesize that patients with undiagnosed sleep apnea are more likely to be more frequent of the clinic compared to those without sleep apnea. We also hypothesize that patients with sleep apnea are more likely to score lower in quality of life measurements at baseline than without sleep apnea and also more likely to score lower than at baseline on repeat testing after they are being told of the diagnosis.
