Budget impact analysis of high-flow nasal cannula for infant bronchiolitis: the Colombian National Health System perspective
Methods: A budget impact analysis was performed to evaluate the potential financial impact deriving from high-flow nasal cannula during 2020. The analysis considered a 5-year time horizon and Colombian National Health System perspective. The incremental budget impact was calculated by subtracting the cost of the new treatment, in which a high-flow nasal cannula is reimbursed, from the cost of the conventional treatment without a high-flow nasal cannula (supplemental oxygen through a nasal cannula up to a maximum of 2 liters per minute). Univariate one-way sensitivity analyses were performed.
Results: In the base-case analysis the 5-year costs associated with high-flow nasal cannula and no- high-flow nasal cannula were estimated to be US$159,585,618 and US$172,751,689 respectively, indicating savings for Colombian National Health equal to US$13,166,071 if the high-flow nasal cannula is adopted for the routine management of patients with acute bronchiolitis. This result was robust in univariate sensitivity one-way analysis.
Conclusion: High-flow nasal cannula was cost-saving in emergency settings for treating infants with acute bronchiolitis. This evidence can be used by decision-makers in our country to improve clinical practice guidelines and should be replicated to validate their results in other middle-income countries.
