This retrospective study is conducted to assess actual uptake of counseling and performance of OS using electronic medical records (EMR) from January 2015 through December 2018 in six different Dutch hospitals: two academic hospitals, two large teaching hospitals, and two non‐teaching hospitals. The year 2015 was considered as representative baseline because three large cohort studies were published at that time showing a risk reduction for EOC after bilateral salpingectomy.6, 7, 8 This prompted several gynecological societies to recommend discussion of OS during abdominal gynecological surgery for other medical indications. During the study period (2015–2018) national guidelines concerning OS had not been issued in the Netherlands, and the nationwide Stop Ovarian Cancer (STOPOVCA) implementation project (ClinicalTrials.gov; NCT04470921) had not started. The aim of STOPOVCA is to optimize implementation of OS by evaluating both healthcare experiences with OS and its influencing factors, and the effect of implementation efforts on the number of eligible women who have actually been counseled about OS.
Informed consent from each patient was not required on account of causing unnecessary harm. Supposedly informing these women of their risk of ovarian cancer and OS that they no longer have access to might cause redundant concerns.
