Healthcare Resource Utilization and Costs Associated With Eosinophilic Esophagitis Among Commercially Insured Patients in the United States.

ABSTRACT

INTRODUCTION: To evaluate real-world healthcare resource utilization (HCRU) and costs associated with eosinophilic esophagitis (EoE) in the United States. METHODS: Retrospective case-control cohort analysis of Optum Clinformatics claims data (January 2008-September 2020) comparing unadjusted and adjusted HCRU (visits per 1,000 patients per month) and all-cause costs (per patient per month). RESULTS: Patients with EoE incurred significantly higher monthly HCRU (adjusted Δ [95% confidence interval] inpatient visits, 2.8 [0.1-4.0]; emergency department visits, 14.7 [4.3-32.1]; outpatient visits, 388.8 [362.1-418.0]); and costs ($581 [$421-$600]) vs matched controls (all P < 0.001). DISCUSSION: EoE imposes substantial economic burden. More effective and targeted treatments that improve outcomes for patients are needed.
