BACKGROUND: Limited decision-support tools are available to help shared decision-making (SDM) regarding food oral immunotherapy (OIT) initiation. No current tool covers all foods, forms, and pediatric ages for which OIT is offered. METHODS: In compliance with International Patient Decision Aid Standards criteria, this pediatric decision-aid comparing OIT versus avoidance was developed in three stages. Nested qualitative data assessing OIT decisional needs were supplemented with evidence-synthesis from the OIT literature to create the prototype decision-aid content. This underwent iterative development with food allergy experts and patient advocacy stakeholders until unanimous consensus was reached regarding content, bias, readability, and utility in making a choice. Lastly, the tool underwent validated assessment of decisional acceptability, decisional conflict, and decisional self-efficacy. RESULTS: The decision-aid underwent 5 iterations, resulting in a 4-page written aid (Flesch-Kincaid reading level 6.1) explaining therapy choices, risks and benefits, providing self-rating for attribute importance for the options and self-assessment regarding how adequate the information was in decision-making. A total of n = 135 caregivers of food-allergic children assessed the decision-aid, noting good acceptability, high decisional self-efficacy (mean score 85.9/100) and low decisional conflict (mean score 20.9/100). Information content was rated adequate and sufficient, the therapy choices wording balanced, and presented without bias for a "best choice." Lower decisional conflict was associated with caregiver-reported anaphylaxis. CONCLUSIONS: This first pediatric OIT decision-aid, agnostic to product, allergen, and age has good acceptability, limited bias, and is associated with low decisional conflict and high decisional self-efficacy. It supports SDM in navigating the decision to start OIT or continue allergen avoidance.
