Abstract

Background: Although atopic diseases and associated comorbidities are prevalent in children, little is known about racial differences in emergency department (ED) visitation.

Objective: We sought to examine racial differences in ED visitation among children with allergic comorbidities.

Methods: We conducted a retrospective study of patients (<21 years) who visited the ED at a large pediatric hospital for atopic dermatitis (AD), food allergy (FA), asthma, allergic rhinitis (AR), and eosinophilic esophagitis (EoE) from 2015 to 2019. We determined the probability of ED encounter-free survival time using hazard ratios (HRs) and time to recurrence (TTR) of ED encounter for patients identified as Black/African American (AA) and White/European American (EA). We assessed potentially underlying allergic, demographic, and place-based factors and potential interactions between factors.

Results: A total of 30,894 patients (38% AA and 62% EA) had 83,078 ED encounters (38,378 first ED encounters and 44,700 recurrent ED encounters) during the study period. Asthma and AR showed the highest rate of comorbidity in ED encounters in both AA and EA children. AA children exhibited a higher HR for encounter following index AD and asthma encounters. We found an interaction between the type of insurance and race in ED encounters for AD, FA, AR, and EoE. In AA children, those insured by Medicaid demonstrated a higher HR for any encounter than those with commercial insurance. Conversely, in EA children, those with Medicaid insurance showed a lower HR than their commercially insured peers. Regardless of race, allergic comorbidity increased the HR of ED encounter (1.12-1.62) for all allergic diseases. At 5-year follow-up, mean differences in TTR were shorter in AA children than EA children in AD, FA, and asthma.

Conclusions: Identification of disease-specific racial disparities in ED visitation related to atopic diseases is a necessary first step toward the design and implementation of interventions capable of equitably reducing emergency care in atopic comorbid children.
