Evaluation of a patient decision aid for opportunistic salpingectomy and salpingectomy as sterilization method to prevent ovarian cancer.

Abstract

Introduction: A patient decision aid on opportunistic salpingectomy and salpingectomy as a sterilization method has been developed to provide uniform counseling and reduce practice variation. The aim of this study was to evaluate the use of the patient decision aid in daily clinical practice to ensure its effectiveness and usability, as well as its influence on the decision-making process and the decision of opportunistic salpingectomy.

Material and methods: As part of the STOPOVCA-implementation study, we conducted a multicenter observational study in 16 hospitals between July 2020 and February 2024. Patients who were eligible for opportunistic salpingectomy were invited to use the decision aid while they considered whether or not to undergo opportunistic salpingectomy. Digital questionnaires were used to evaluate the decision aid, the decision process, and patients' decisions 6-8 weeks post-surgery.

Results: 425 out of 542 patients participated in the questionnaire. A majority of these 425 patients received (N = 357; 84%) and used the decision aid (N = 347; 82%). Two thirds (N = 234; 67%) of those who used the decision aid stated that it increased their knowledge of opportunistic salpingectomy. Patients considered the decision aid a usable aid, allocating a score of 8.1 out of 10 and would recommend it to other patients facing the decision regarding opportunistic salpingectomy. Patients considered the extent to which they were involved in the decision-making process as high, and the decisional conflict low. The majority of patients who used the decision aid opted for opportunistic salpingectomy (N = 326; 95%). Main reasons for choosing opportunistic salpingectomy were the risk-reducing effect of ovarian cancer (N = 311; 90%) and the lack of functionality of the fallopian tubes after childbearing (N = 320; 92%).

Conclusions: The patient decision aid was used by a majority of patients who received it. The decision aid was regarded by patients as user-friendly, and it was recommended to be used in the decision-making process for opportunistic salpingectomy. Patients stated that the decision aid provides reliable information and increases patients' knowledge of opportunistic salpingectomy.
