Cost and accessibility of empiric food elimination diets for treatment of eosinophilic oesophagitis.

Aim: This study aimed to investigate and compare the cost, affordability, and accessibility of three elimination diet approaches for the treatment of patients with eosinophilic esophagitis: the two-, four- and six-food elimination diets and with comparison to a standard diet.

Methods: An evidence-based modelling process was undertaken for costing and accessibility, including the development of three hypothetical reference families; four food baskets were modified from an established benchmark for each diet. Baskets were costed across eastern Melbourne, Australia.
