Abstract
OBJECTIVES: We examined (1) disparities in obstructive sleep apnea (OSA) care by insurance coverage, and by child race and ethnicity among Medicaid-insured children (MIC), and (2) healthcare utilization changes after OSA care. METHODS: IBM MarketScan insurance claims were used to index OSA care 1-year before and after initial OSA diagnosis in 2017 among 2-17-year-old children (n = 31,787, MIC: 59%). OSA care and healthcare utilization analyses adjusted for child age, sex, obesity, and complex chronic conditions. RESULTS: We identified 8 OSA care pathways, including no care, which occurred in 34.4% of the overall sample. MIC had 13% higher odds of no OSA care compared to commercially-insured children (CIC). MIC had 32-48% lower odds of any treatment pathway involving specialty care, but a 13-46% higher likelihood of receiving surgical care without polysomnogram (PSG) and PSG only. In MIC, non-Latinx Black/African American (Black) and Hispanic/Latinx children were 1.3-2.2 times more likely than White children to receive treatment involving specialty care and/or PSG, while Black children were 31% less likely than White youth to undergo surgery. In the full sample, surgical care was associated with less outpatient and emergency healthcare utilization compared to those untreated or not surgically treated. CONCLUSIONS: Varied OSA management by insurance coverage suggests disparities in access to and engagement in care and potentially greater disease burden among MIC. Surgical care is associated with reduced healthcare utilization. The lower odds of surgery in Black MIC should be further evaluated in the context of OSA severity, healthcare biases, and family preferences.
