摘要
Background: Children with allergic rhinitis (AR) often experience significant impairment in quality of life and health, which increases health care utilization. Objective: To determine whether allergen immunotherapy reduces health care utilization and costs in children newly diagnosed as having AR using a retrospective matched cohort design. Methods: Among children (age <18 years) with a Florida Medicaid paid claim between 1997 and 2007, immunotherapy-treated patients were selected who had newly diagnosed AR, who had not received immunotherapy before their first (index) AR diagnosis, who had received at least 2 immunotherapy administrations after their index AR diagnosis, and who had at least 18 months of data after their first immunotherapy administration. A control group of patients with newly diagnosed AR who had not received immunotherapy either before or subsequent to their index AR diagnosis also were identified, and up to 5 were matched with each immunotherapy-treated patient by age at first AR diagnosis, sex, race/ethnicity, and diagnosis of asthma, conjunctivitis, or atopic dermatitis. Results: Immunotherapy-treated patients had significantly lower 18-month median per-patient total health care costs ($3,247 vs $4,872), outpatient costs exclusive of immunotherapy-related care ($1,107 vs $2,626), and pharmacy costs ($1,108 vs $1,316) compared with matched controls (P < .001 for all). The significant difference in total health care costs was evident 3 months after initiating immunotherapy and increased through study end. Conclusions: This study demonstrates the potential for early and significant cost savings in children with AR treated with immunotherapy. Greater use of this treatment in children could significantly reduce AR-related morbidity and its economic burden. Ann Allergy Asthma Immunol. 2010; 104: 79-85.
