Outcome and Cost Analysis of Sacral Nerve Modulation for Treating Urinary and/or Fecal Incontinence

Sacral nerve modulation (SNM) is an established treatment for urinary and fecal incontinence in patients for whom conservative management has failed.This study assessed the outcome and cost analysis of SNM compared to alternative medical and surgical treatments.Clinical outcome and cost-effectiveness analyses were performed in parallel with a prospective, multicenter cohort study that included 369 consecutive patients with urge urinary and/or fecal incontinence. The duration of follow-up was 24 months, and costs were estimated from the national health perspective. Cost-effectiveness outcomes were expressed as incremental costs per 50% of improved severity scores (incremental cost-effectiveness ratio).The SNM significantly improved the continence status (P0.005) and quality of life (P0.05) of patients with urge urinary and/or fecal incontinence compared to alternative treatments. The average cost of SNM for urge urinary incontinence was ∈8525 (95% confidence interval, ∈6686-∈10,364; P = 0.001) more for the first 2 years compared to alternative treatments. The corresponding increase in cost for subjects with fecal incontinence was ∈6581 (95% confidence interval, ∈2077-∈11,084; P = 0.006). When an improvement of more than 50% in the continence severity score was used as the unit of effectiveness, the incremental cost-effectiveness ratio for SNM was ∈94,204 and ∈185,160 at 24 months of follow-up for urinary and fecal incontinence, respectively.The SNM is a cost-effective treatment for urge urinary and/or fecal incontinence.
