Impact of race and socioeconomic deprivation on clinical outcomes and healthcare utilization in pediatric multiple sclerosis.

Background: Health disparities in adult-onset multiple sclerosis have been identified in the Black/African American (AA) population. A higher relapse rate has been suggested in Black/AA patients with pediatric-onset MS (POMS), but little work explores healthcare utilization and social determinants of health (SDOH).

Objective: To evaluate racial, ethnic, and socioeconomic disparities in POMS outcomes.

Methods: Retrospective chart review identified 31 eligible patients diagnosed with POMS at Children's of Alabama between 2013 and 2023. Demographics, outcomes, and healthcare utilization over 2 years from diagnosis were collected. Patient addresses were connected to SDOH measures from the US Census. Bivariate analysis was performed using Fisher's Exact Test, Wilcoxin Test, and 2-sided t-test.

Results: Black/AA children had a higher Expanded Disability Status Scale (EDSS) at first presentation (p = 0.0276) and were more likely to initiate fingolimod vs. glatiramer acetate (p = 0.0464). Living further from Children's of Alabama was associated with a higher most recent EDSS (p = 0.0301) and fewer neurology appointments (p = 0.0167). Families living in more socioeconomically deprived census tracts had significantly more hospital admissions.

Conclusion: Black/AA POMS patients had a more severe initial presentation and were started on higher efficacy medication. We identified disparities in EDSS and healthcare utilization based on SDOH data linked to a child's home address.
