Current Knowledge/Study Rationale: While the prevalence of OSA in the US is estimated at approximately 25%, it is likely that the prevalence in the in-hospital population is higher. This is because OSA is associated with many medical conditions, such as congestive heart failure, cardiovascular and cerebrovascular disease, postoperative complications, and exacerbations of chronic conditions. Despite this, the prevalence of undiagnosed OSA among hospitalized patients is unknown. Moreover, studies show screening for sleep complaints does not routinely occur in either the clinic or hospital setting.
Study Impact: Understanding the prevalence of OSA as well as the relationship of OSA with inpatient sleep quality is important for recognizing high-risk inpatients as well as diagnosing and treating those who may have OSA. Also, by better understanding where physician knowledge of screening for OSA is lacking, we can hopefully increase awareness of this shortfall and train hospital staff nationwide to recognize and screen patients for sleep disorders.
