Abstract: Rationale: Food allergy is documented to result in considerable morbidity, negative impact on quality of life, and substantial medical care costs. Although anecdotal data suggest widely varying practices in the diagnosis and management of food allergies, the diversity and relative frequency of these practices have not been documented. Methods: A questionnaire was developed evaluating allergists’ management approaches of individuals with peanut allergy (PA) in Germany (DE), France (FR), and the United Kingdom (UK). Results: Here, we report the survey results from a total of 109 allergists from DE, FR and the UK. They reported to confirm PA at initial diagnosis using skin prick test (≥60%), while allergists from DE and FR reported using allergen-specific IgE testing more (>86%) compared to the UK ( 75%). Half of the responders reported assessing the patient’s quality of life. 63% allergists reported retesting for PA resolution at a later date, with 45% allergists indicated to recommend ingestion of a normal serving of peanut regularly upon resolution. Lack of effective PA treatment was reported to be a ‘very significant’ barrier for optimal PA treatment, with allergists being less than ‘moderately familiar’ with data from clinical trials testing new treatments options for PA. Lastly, allergists stated that the severity of patient’s PA ranked as the most important factor in their decision to recommend oral immunotherapy for PA treatment. Conclusions: This survey provides essential insights into the practice of allergists and highlights some areas that would inform strategies for education and improving PA healthcare.
