Objectives:
We examined the cost-effectiveness of treating poorly controlled, severe, persistent asthma patients with bronchial thermoplasty (BT), a novel technology that uses thermal energy to reduce airway smooth muscle mass, with 5-year outcome data demonstrating a durable reduction in asthma exacerbations.
Study Design:
We conducted a model-based cost-effectiveness analysis assessing 5-year healthcare utilization, patient quality of life and adverse events.
Methods:
We utilized Markov modeling to estimate the costs and quality-of-life impact of BT compared with high-dose combination therapy among poorly controlled, severe, persistent asthma patients: those requiring high-dose combination therapy and having experienced an asthma exacerbation-related ER visit in the past year.
Results:
The cost-effectiveness of BT was US$5495 per quality-adjusted life year; and approximately 22% of sensitivity analysis iterations estimated BT to reduce costs and increase quality of life.
Conclusions:
BT is a cost-effective treatment option for patients with poorly controlled, severe, persistent asthma.
