Popis: Introduction The prevalence of Obstructive Sleep Apnea (OSA) among medical intensive care unit (MICU) patients is unknown. However, OSA prevalence in the general population and in conditions that are frequently comorbid in ICU populations (e.g., diabetes and cardiovascular disease) suggests that OSA may be common among MICU patients. Our objective is to prospectively examine the prevalence and severity of OSA in patients admitted to a tertiary academic MICU. Methods This was a prospective observational study that included patients admitted to the MICU from July to December 2022. Patient charts were reviewed for patient demographics, clinical characteristics, and evidence of pre-existing OSA. Pre-existing OSA was assessed via in depth review of the electronic medical record and included data fields such as the past medical history, documentation of OSA treatment, description of OSA diagnosis in outpatient provider notes, and/or sleep study records. Based on chart review, we also assigned confidence ratings for the OSA diagnosis (high versus low) and noted patients for whom outpatient providers had a high clinical suspicion for OSA in the absence of definitive sleep evaluation. Results Herein, we present preliminary analysis of 345 MICU patients. Mean age (SD) was 64 (18) years; 49% were female, 23% were Black, and 67% were White. Acute respiratory failure (36%) and septic shock (24%) were the leading reasons for admission. Mean (SD) APACHE II severity of illness score was 19.6 (8.8) and body mass index was 27.5 (8.5). Pre-existing OSA was identified in 19% of patients; 63% of pre-existing OSA patients were characterized as “high confidence” in OSA diagnosis. An additional 6% of patients had high clinical suspicion of OSA. Severity data was sparse in the chart with only 17% of OSA patients having severity data available; OSA severity distribution was as follows: mild 9%, moderate 27%, and severe 64%. Conclusion Our preliminary analysis indicates that OSA is notably prevalent among MICU patients. We hypothesize that OSA is under-recognized and consequently undertreated in MICU patients. With this in mind, future directions include investigation of the recognition, treatment, and outcomes related to pre-existing OSA in critically ill patients. Support (if any) NHLBI, NIH T35HL007649
