Abstract
Introduction and hypothesis
The purpose of this study was to assess cost utility of duloxetine versus tension-free vaginal tape (TVT) as a second-line treatment for urinary stress incontinence.
Methods
A Markov model was used to compare the cost utility based on a 2-year follow-up period. Quality-adjusted life year (QALY) estimation was performed by assuming a disutility rate of 0.05.
Results
Under base-case assumptions, although duloxetine was a cheaper option, TVT gave a considerably higher QALY gain. When a longer follow-up period was considered, TVT had an incremental cost-effectiveness ratio (ICER) of £7,710 ($12,651) at 10 years. If the QALY gain from cure was 0.09, then the ICER for duloxetine and TVT would both fall within the indicative National Institute for Health and Clinical Excellence willingness to pay threshold at 2 years, but TVT would be the cost-effective option having extended dominance over duloxetine.
Conclusions
This model suggests that TVT is a cost-effective treatment for stress incontinence.
