Geographic disparities in performance of pediatric polysomnography to diagnose obstructive sleep apnea in a universal access health care system

Diagnostic polysomnography (PSG) is recommended prior to adenotonsillectomy (AT) for children with obstructive sleep apnea (OSA) and certain high-risk characteristics, but resource limitations often prevent this practice.

Description
Summary:Diagnostic polysomnography (PSG) is recommended prior to adenotonsillectomy (AT) for children with obstructive sleep apnea (OSA) and certain high-risk characteristics, but resource limitations often prevent this practice. We performed a population-based assessment of children across Ontario, Canada to describe and quantify disparities in PSG. This retrospective cohort study was performed using provincial health administrative data held at ICES. We identified children 0–10 years old who underwent PSG and AT between 2009 and 2018, and those with a PSG within 18 months prior to and/or 12 months following AT. We calculated the odds of PSG prior to/following AT after adjustment for demographics, medical comorbidities, geographic and socioeconomic characteristics. Our main predictor was driving time/distance to the nearest pediatric sleep centre ascertained using spatial analysis and geographic information systems. We identified 27,837 children
