Adoption of Complete Bilateral Salpingectomy for Permanent Contraception at Time of Cesarean Delivery in Rhode Island.

OBJECTIVE: Complete bilateral salpingectomy (CBS) can decrease the risk of developing ovarian cancer, although adoption of CBS at cesarean delivery (CD) for permanent contraception has been low. The primary objective was to measure the annual rates of CBS at CD before and after an educational initiative. The secondary objective was to assess rates of providers who offer CBS at CD and their comfort level with the procedure.

METHODS: We performed an observational study of OBGYN physicians who perform CD at a single institution. We compared the annual rates of CBS among CD with permanent contraception procedures from the year before and the year after an in-person OBGYN Grand Rounds presentation on December 5, 2019 reviewing the latest research on opportunistic CBS at the time of CD. To evaluate the secondary objectives, anonymous surveys were administered to physicians in-person the month before the presentation. The statistical analysis included chi-square, Fisher's exact test, T-test, ANOVA, and the Cochran-Armitage trend test.

RESULTS: After our educational intervention, annual rates of CBS at CD increased from 5.1% [12/05/2018-12/04/2019] to 31.8% [12/5/2019-12/4/2020] (p<0.001), and up to 52% in the last study quarter (p<0.001). Surgical outcomes were similar between tubal ligation and CBS, except for a 5-minute increased total operative time for CBS (p=0.005). Fifty physicians completed the survey prior to the presentation (93% response rate). All physicians offered CBS at time of hysterectomy and interval sterilization, while only 36% offered CBS at time of CD. More physicians felt comfortable performing a CBS with bipolar electrocautery (90%) than suture ligation (56%).

CONCLUSION: Our presentation-based educational initiative was associated with a significant increase in performance of CBS at the time of CD.
