International Survey on Evaluation and Management of Eosinophilic Esophagitis

Background: : Recommendations regarding evaluation and management of eosinophilic esophagitis (EoE) remain incompletely defined. This survey assesses: how providers across the world diagnose, evaluate, and treat EoE and how educational activities affect management.

Methods: : A web-based survey was sent to the members of World Allergy Organization, American College of Allergy, Asthma, and Immunology, and American Academy of Allergy, Asthma, and Immunology. A χ analysis compared responses based on personal and practice demographics and participation in educational activities.

Results: : Of the 200 respondents, 68.5% were from the United States. The majority were allergists, who require biopsy to diagnose EoE, perform allergy testing, and obtain follow-up biopsy after treatment. The following variables had significant differences: (1) US practitioners were more likely to test for immediate-type hypersensitivity to foods and obtain follow-up endoscopic biopsies after the initial treatment; (2) Practitioners encountering patients with EoE more frequently were more likely to ask about personal and family history of atopy, test for immediate-type hypersensitivity to aeroallergens and foods, and recommend follow-up biopsy after treatment; and (3) Practitioners who participate more often in EoE workshops were more likely to perform patch testing for foods, while attendance at EoE lectures increased EoE management confidence.

Conclusions: : Diagnostic and management strategies differ based on practice location, EoE patient load, and participation in educational activities. Practitioners who attend more EoE lectures are more confident managing EoE.
