BACKGROUND: @entity27 ( @entity27 ) affects approximately 20% of US adults, of whom about 90% are undiagnosed. While @entity27 may increase risk of perioperative complications, its prevalence among surgical @entity1 is unknown. We tested the feasibility of screening surgical @entity1 for @entity27 and determined the prevalence of undiagnosed @entity27 . METHODS: In a prospective, observational study adult surgical @entity1 were screened for @entity27 in an academic hospital. @entity1 without an @entity27 diagnosis who screened high-risk were offered a home sleep study to determine if they had @entity27 . The results were compared with polysomnography (PSG) when available. Charts of high-risk @entity1 were examined for @entity260 . High-risk @entity1 received targeted interventions as part of a hospital safety initiative. RESULTS: There were 2877 @entity1 screened; 661 (23.7%) screened high-risk for @entity27 , of whom 534 (81%) did not have diagnosed @entity27 . The portable sleep study detected @entity27 in 170/207 (82%) high-risk @entity1 without diagnosed @entity27 . Twenty-six PSGs confirmed @entity27 in 19 of these @entity1 . Postoperatively there were no respiratory arrests, two unanticipated ICU admissions, and five documented respiratory complications. CONCLUSION: Undiagnosed @entity27 is prevalent in adult surgical @entity1 . Implementing universal screening is feasible and can identify undiagnosed @entity27 in many surgical @entity1 . Further investigation is needed into perioperative complications and their prevention for @entity1 with undiagnosed @entity27 .
