Study Objectives: Sleep-disordered breathing (SDB) may significantly impact the course of medical illness in hospitalized children. Polysomnography (PSG) is the gold standard for establishing diagnosis of SDB, but its availability is limited. The aim of this study was to explore the feasibility and utility of level III portable sleep studies in hospitalized children with SDB. Methods: A retrospective study was conducted at a tertiary hospital over the preceding 2 years in hospitalized children < 18 years who had undergone a level III sleep study using the Nox T3 system. The information obtained included demographic data, comorbidities, indication for admission and sleep study, time interval between the study ordered and done, adequacy of technical data from sleep study, study diagnosis, and subsequent management interventions for SDB. Results: A total of 51 hospitalized children had these studies; 32 were female and mean age was 4.3 years. Approximately 90% of children had significant comorbidities, including neurological and craniofacial abnormalities. The majority (80%) of studies were conducted within 24 hours of the time requested and 92.1% studies had technically adequate data for analysis. Thirty-nine (76.5%) children were identified with SDB; all but one patient underwent therapy for SDB during that same hospitalization, including supplemental oxygen (48.7%), positive airway pressure therapy (23%), surgical intervention (38.2%) or caffeine (10.2%). Twelve percent of children had more than one intervention done. Conclusions: The level III portable sleep study is readily available, sufficient to diagnose SDB, and help to provide appropriate medical and/or surgical therapies in hospitalized children with complex medical conditions.
