Cost-effectiveness of Surgical Treatment Pathways for Prolapse.

Abstract

To evaluate the cost-effectiveness of surgical treatment pathways for apical prolapse. We constructed a stochastic Markov model to assess the cost-effectiveness of vaginal apical suspension, laparoscopic sacrocolpopexy, and robotic sacrocolpopexy. We modeled over 5 and 10 years, with 9 pathways accounting for up to 2 separate surgical repairs, recurrence of symptomatic apical prolapse, reoperation, and complications, including mesh excision. We calculated costs from the health care system's perspective. Over 5 years, compared with expectant management, all surgical treatment pathways cost less than the willingness-to-pay threshold of US $50,000 per quality adjusted life-years. However, among surgical treatments, all but 2 pathways were dominated. Of the remaining 2, laparoscopic sacrocolpopexy followed by vaginal repair for apical recurrence was not cost-effective compared with the vaginal-only approach (incremental cost-effectiveness ratio [ICER], >$500,000). Over 10 years, all but the same 2 pathways were dominated. However, starting with the laparoscopic approach in this case was more cost-effective with an ICER of US $6,176. If the laparoscopic approach was not available, starting with the robotic approach similarly became more cost-effective at 10 years (ICER, US $35,479). All minimally invasive surgical approaches for apical prolapse repair are cost-effective when compared with expectant management. Among surgical treatments, the vaginal-only approach is the only cost-effective option over 5 years. However, over a longer period, starting with a laparoscopic (or robotic) approach becomes cost-effective. These results help inform discussions regarding the surgical approach for prolapse.
