ABSTRACT
INTRODUCTION:
The aim is to perform an economic evaluation alongside a randomized controlled trial comparing guided self-help cognitive behavioral therapy-enhanced (CBT-E) for binge-eating disorder (BED) to a waiting list control condition.METHODS:
BED patients (N = 212) were randomly assigned to guided self-help CBT-E or the 3-month waiting list. Measurements took place at baseline and the end-of-treatment. The cost-effectiveness analysis was performed using the number of binge-eating episodes during the last 28 days as an outcome indicator according to the eating disorder examination. A cost-utility analysis was performed using the EuroQol-5D.RESULTS:
The difference in societal costs over the 3 months of the intervention between both conditions was 679 (confidence interval [CI] 50-1330). The incremental costs associated with one incremental binge eating episode prevented in the guided self-help condition was approximately 18 (CI 1-41). From a societal perspective there was a 96% likelihood that guided self-help CBT-E led to a greater number of binge-eating episodes prevented, but at higher costs. Each additional quality-adjusted life year (QALY) gained was associated with incremental costs of 34,000 (CI 2494-154,530). With a 95% likelihood guided self-help CBT-E led to greater QALY gain at higher costs compared to waiting for treatment. Based on the National Institute for Health and Clinical Excellence willingness-to-pay threshold of 35,000 per QALY, guided self-help CBT-E can be considered cost-effective with a likelihood of 95% from a societal perspective.DISCUSSION:
Guided self-help CBT-E is likely a cost-effective treatment for BED in the short-term (3-month course of treatment). Comparison to treatment-as-usual is recommended for future research, as it enables an economic evaluation with a longer time horizon. PUBLICSIGNIFICANCE:
Offering treatment remotely has several benefits for patients suffering from binge-eating disorders. Guided self-help CBT-E is an efficacious and likely cost-effective treatment, reducing binge eating and improving quality-of-life, albeit at higher societal costs.Palabras clave
