Abstract
Study objectives: Sleep-disordered breathing is prevalent in children with sickle cell disease (SCD) and is associated with worse outcomes. This study aimed to compare the outcomes of polysomnography (PSG) performed for pediatric patients with SCD at 3 US centers.
Methods: We included patients with SCD aged 0-21 years who underwent PSG at 3 American Academy of Sleep Medicine-accredited centers, the University of Alabama at Birmingham, the University of Florida, and Duke University Hospital, between 2012 and 2022. Descriptive statistics were used as appropriate to compare the baseline characters and PSG outcomes among the different centers.
Results: A total of 210 children with SCD from the 3 centers were included, with comparable sex, SCD genotypes, hemoglobin, hematocrit levels, and chronic transfusion. Children from the different centers exhibited variations in age (P < .001), body mass index (P < .05), mean corpuscular volume (P < .05), and hydroxyurea usage (P < .05) at the time of the PSG. Overall, the 3 centers showed significantly different PSG outcomes. Patients from the University of Florida had worse obstructive sleep apnea, oxygenation, and periodic leg movement events, together with lower hydroxyurea usage, and those from Duke University Hospital showed higher hypoventilation and arousal indices.
Conclusions: This multicenter study underscores variations in PSG outcomes among pediatric SCD patients at different centers in the southeastern United States. These findings emphasize the need for standardized approaches to screen for sleep-disordered breathing, refer to PSG, and interpret the results in children with SCD. These conclusions may apply to other genetic disorders associated with an increased risk of sleep-disordered breathing.

期刊介绍：
Journal of Clinical Sleep Medicine focuses on clinical sleep medicine. Its emphasis is publication of papers with direct applicability and/or relevance to the clinical practice of sleep medicine. This includes clinical trials, clinical reviews, clinical commentary and debate, medical economic/practice perspectives, case series and novel/interesting case reports. In addition, the journal will publish proceedings from conferences, workshops and symposia sponsored by the American Academy of Sleep Medicine or other organizations related to improving the practice of sleep medicine.
