Objectives: Opportunistic salpingectomy is a cost-effective strategy recommended for ovarian cancer (OvCa) risk reduction at the time of gynecologic surgery in women who have completed childbearing. We aimed to evaluate the cost-effectiveness of opportunistic salpingectomy compared to standard tubal ligation (TL) during cesarean delivery. Study design: A cost-effectiveness analysis using decision modeling to compare opportunistic salpingectomy to TL at the time of cesarean using probabilities of procedure completion derived from a trial. Probability and cost inputs were derived from local data and the literature. The primary outcome was the incremental cost-effectiveness ratio (ICER) in 2017 U.S. dollars per quality-adjusted life year (QALY) at a cost-effectiveness threshold of $100,000/QALY. One- and two-way sensitivity analyses were performed for all variables. A probabilistic sensitivity analysis determined the proportion of simulations in which each strategy would be cost-effective. Results: Opportunistic salpingectomy was cost-effective compared to TL with an ICER of $26,616 per QALY. In 10,000 women desiring sterilization with cesarean, opportunistic salpingectomy would result in 17 fewer OvCa diagnoses, 13 fewer OvCa deaths, and 25 fewer unintended pregnancies compared to TL – with an associated cost increase of $4.7 million. The model was sensitive only to OvCa risk reduction from salpingectomy and TL. Opportunistic salpingectomy was not cost-effective if its cost was >$3163.74 more than TL, if the risk-reduction of salpingectomy was <41%, or if the risk-reduction of TL was >46%. In probabilistic sensitivity analysis opportunistic salpingectomy was cost effective in 75% of simulations. Conclusions: In women undergoing cesarean with sterilization, opportunistic salpingectomy is likely cost-effective and may be cost-saving in comparison to TL for OvCa risk reduction.
