Food allergies affect 8% of the pediatric population in the United States with an estimated annual cost of US$25 billion. The low specificity of some of the main food allergy tests used in diagnosis may generate false positives incurring unnecessary costs. We examined the cost-effectiveness of oral food challenges (OFC) as confirmatory tests in the diagnosis of food allergy. Methods. We constructed a decision tree with a Markov model comparing the long-term (15 years) cost and effectiveness-in the form of quality-adjusted life years (QALY)-of confirmatory OFCs compared with immediate allergenic food elimination (FE) after a skin prick test or blood immunoglobulin E (IgE) level in children with suspected food allergy. For costs, we included the costs of OFCs and the reported annual costs of having a food allergy, including direct medical costs and costs borne by families. Results. The cost of OFC strategy was $8671 compared with $18 012 for the FE strategy for the length of the model. Also, the OFC strategy had a total QALY of 21.942 compared with 21.740 for the FE strategy. In the OFC strategy, the total cost was $9341 less than FE and the increase in QALY after OFCs led to a 0.202 higher effectiveness in the OFC strategy. Conclusion. In conclusion, our study shows that the confirmatory OFC strategy dominated the FE strategy and that a confirmatory OFC for children, within a year of diagnosis, is a cost-effective strategy that decreases costs and appears to improve quality of life.
