Association of Race and Ethnicity With Emergency Room Rate of Migraine Diagnosis, Testing, and Management in Children With Headache.

BACKGROUND AND

objectivesHeadache evaluation and treatment are believed to be influenced by race and ethnicity. Specific headache diagnosis assigned in the pediatric emergency department (ED) may compound disparities. We sought to investigate racial and ethnic disparities in the diagnosis, testing, and treatment of pediatric patients with headache presenting to the ED.

methodsWe performed a cross-sectional analysis of ED visits from 49 children's hospitals between 2016 and 2022 from the Pediatric Health Information System, an administrative database of ED and hospitalized encounters within children's hospitals in the United States. Index encounters in the ED from patients (aged 5-21 years, median age 13 [10-15]) with a primary diagnosis of migraine, headache, new daily persistent headache, or tension-type headache were included. Encounters with trauma, infection, and malignancy where secondary headache was possible were excluded. The primary outcomes were the rates of migraine diagnosis, testing, and treatment. We used generalized estimating equations to estimate associations between race and ethnicity and outcomes after adjusting for demographic factors, medical complexity, visit timing, and final headache diagnosis.

resultsA total of 309,678 encounters were included while 61,677 repeat visits, 81,821 visits with diagnoses suggestive of secondary headache, and 5,714 visits from 3 hospitals with sparse data on patient race/ethnicity were excluded. Of 160,466 eligible visits (59.8% female), 41% were by non-Hispanic White (NHW) children, 24.8% non-Hispanic Black (NHB), and 26.0% Hispanic/Latino (HL). NHW children were more frequently diagnosed with migraine (45.5% vs NHB 28.2% and HL 28.3%, DISCUSSION: NHB and HL children in the pediatric ED with headache receive fewer migraine diagnoses, less testing, and less intensive treatment compared with NHW children. Beyond affecting headache management, this inequity in migraine diagnosis requires further consideration to include children from marginalized racial and ethnic groups in future migraine research.
