1053 Patients’ Sleep Perception and Its Correlation with Unattended Ambulatory Testing in the Inpatient Setting

Abstract Introduction Obstructive sleep apnea is an increasingly prevalent condition today, with many cardiopulmonary consequences. In the ambulatory setting when a patient reports poor sleep quality on the night of the study, repeat testing is usually sought out. Here, we examine the differences in AHI, ODI and comorbidities among patients who perceived they slept well versus patients who perceived they slept poorly and compare it to outpatient PSG follow up. Methods A retrospective chart review of 1351 patients enrolled in a formal hospital sleep medicine program between September 2019 and October 2022, was conducted. The sleep medicine team asked each patient how they perceived they slept that night, using three options: slept well, slept but not well, or slept very poorly. Patients who slept but not well and patients who slept very poorly were combined to make a category of slept poorly. From there, each patient’s AHI, ODI, Stop-Bang score, ESS score and comorbidities were monitored. Results Of the 1351 patients 304 of these patients had outpatient follow up with PSG. The STOP-BANG score for patients who slept well and slept poorly was 5.17 and 5.48, respectively. In the patients who slept poorly, 73% had a mean AHI >5 on confirmatory PSG compared to 79% while inpatient. The patients who slept well, 79% had a mean AHI >5 on confirmatory PSG compared to 73% while inpatient. Conclusion The variables used to measure sleep apnea were not significantly different among patients who believed they slept well versus patients who believed they slept poorly. Current thought is that inpatient sleep medicine can lead to false positive results, as patients are sicker in the inpatient setting, leading to poorer sleep quality and disruption that could alter their unattended sleep study. In this retrospective chart review, there seemed to be little difference when comparing patients’ hospital sleep studies to their outpatient ones. Only 22% of patients completed outpatient follow up. This needs further evaluation to see if streamlined care for the patients leads to better outcomes and cost-effective care. Support (if any)
