FoodCHOMP (Food Challenge—at HOme or in Medical Practice): a pilot multicentre randomised controlled trial evaluating home versus clinic-based food allergy challenges in low-risk adults–study protocol

Abstract

Introduction Approximately 6%–10% of adults carry food allergy labels. Many such labels are unverified and may be incorrect, contributing to delays in appropriate care, significant dietary restriction, anxiety and unnecessary use of emergency medications. Oral food challenges (OFCs) are the gold standard for confirming or excluding food allergy, but the current model of clinic-based challenges often has long wait times and logistical barriers. This study aims to investigate the feasibility and safety of home-based OFCs compared with standard in-clinic challenges in adults with negative skin-prick testing. Methods and analysis Food Challenge at HOme or in Medical Practice is a pilot multicent..
