RESUMO
OBJECTIVE: Using data from the Canadian Bronchiolitis Epinephrine Steroid Trial we assessed the cost-effectiveness of treatments with epinephrine and dexamethasone for infants between 6 weeks and 12 months of age with bronchiolitis. METHODS: An economic evaluation was conducted from both the societal and health care system perspectives including all costs during 22 days after enrollment. The effectiveness of therapy was measured by the duration of symptoms of feeding problems, sleeping problems, coughing, and noisy breathing. Comparators were nebulized epinephrine plus oral dexamethasone, nebulized epinephrine alone, oral dexamethasone alone, and no active treatment. Uncertainty around estimates was assessed through nonparametric bootstrapping. RESULTS: The combination of nebulized epinephrine plus oral dexamethasone was dominant over the other 3 comparators in that it was both the most effective and least costly. Average societal costs were $1115 (95% credible interval [CI]: 919-1325) for the combination therapy, $1210 (95% CI: 1004-1441) for no active treatment, $1322 (95% CI: 1093-1571) for epinephrine alone, and $1360 (95% CI: 1124-1624) for dexamethasone alone. The average time to curtailment of all symptoms was 12.1 days (95% CI: 11-13) for the combination therapy, 12.7 days (95% CI: 12-13) for no active treatment, 13.0 days (95% CI: 12-14) for epinephrine alone, and 12.6 days (95% CI: 12-13) for dexamethasone alone. CONCLUSION: Treating infants with bronchiolitis with a combination of nebulized epinephrine plus oral dexamethasone is the most cost-effective treatment option, because it is the most effective in controlling symptoms and is associated with the least costs.
