0697 Gender Bias with Centers for Medicare and Medicaid Services Scoring Criteria when Diagnosing Obstructive Sleep Apnea

Introduction Women with obstructive sleep apnea (OSA) have less hypoxemia during sleep and a lower apnea-hypopnea index (AHI) when compared to men. Therefore, symptomatic women may be less likely than men to meet the Centers for Medicare and Medicaid Services (CMS) criteria for the diagnosis of OSA. We hypothesized that utilizing CMS criteria for diagnosing OSA, as compared to AASM scoring criteria, underestimates the prevalence of OSA in women and precludes symptomatic women from receiving therapy. Methods We reviewed retrospective data on 741 subjects (219 men and 522 women) who underwent a diagnostic polysomnography at an urban academic sleep center from January to November 2018. Included subjects were >18 years of age and had both a CMS and AASM AHI documented. A univariate logistic regression was performed to evaluate the association between the outcome (CMS score
