Background: Peanut allergy (PA) affects ∼1.6 million US children. The current standard of care is strict avoidance and prompt reaction treatment. PA healthcare costs and healthcare resource utilization (HCRU) are poorly understood. Objective: To estimate PA healthcare costs and HCRU using a nationally representative commercial payer database. Methods: The IBM MarketScan ® Commercial Claims and Encounters Database was examined for PA diagnosis/reaction codes between January 2011 and October 2015 in patients ≤64 years, with age cohort-matched controls. Outcomes were measured 12 months before and after the first claim date. Healthcare costs and HCRU were compared using Student's t-tests and chi-square tests. Results: Patients with a PA-related diagnostic code (n=41,675) incurred almost double all-cause healthcare costs versus controls ($6436 vs $3493, P <0.001), mainly from inpatient and outpatient medical costs ($5002 vs $2832, P <0.001). Over 1/3 of the PA group patients (36%) had a code indicative of an anaphylactic reaction during follow-up. Mean PA or reaction-related code costs per visit totaled $7921 for hospitalizations and $1115 for emergency department (ED) visits. Costs were 30% lower in patients with asthma codes without PA codes versus those with both codes ($5678 vs $8112, P <0.001); all-cause ED costs were more than double in patients with atopic dermatitis codes with PA codes versus those without PA codes ($654 vs $308, P <0.001). Conclusion: National commercial payer claims data indicate a significant healthcare burden associated with a PA-related code, including over $6400/patient in annual allcause costs and increased healthcare utilization.
