0528 Use of Inpatient Sleep Studies Decreases Time to Treatment in Patients with Obstructive Sleep Apnea (OSA)

Abstract Introduction OSA remains underdiagnosed in the general population and when left untreated, can have an effect on chronic illnesses including exacerbation of disease processes, potentially increasing hospitalization. The diagnosis of OSA in patients admitted to the hospital is important, however the time from hospital discharge to sleep study and then to OSA treatment can be prolonged. We aim to assess differences in outcomes between hospital admitted patients who undergo OSA workup during admission vs in the outpatient setting . Methods retrospective chart review with prospective component Results 65 patients included all seen by sleep medicine service while admitted to the hospital and required workup for OSA; 57 received outpatient workup- 11/57 completed their sleep study (19%), all of which were prescribed PAP therapy for OSA. 2/57 (3.5%) had subsequent follow up by 6 months. Average time to diagnosis was 46 +/- 48 days and time to CPAP prescription was 56 +/- 53 days. 8 patients underwent inpatient OSA workup. All obtained a sleep study while in the hospital within 1 day of the consult; 6/8 were diagnosed with OSA all of which had the process started for CPAP set up within 2 days of sleep study. The time to diagnosis and start to treatment process was significantly less than the outpatient group (p 0.05). We are currently collecting data on long term health outcomes for these patients. Conclusion Inpatient sleep studies for OSA work up has the potential to decrease time to OSA diagnosis and time to treatment for patients. This new workflow may have the potential to improve long term health outcomes. Support (if any)
