A Delphi consensus study among patients and clinicians in the Netherlands on the procedure of informing young breast cancer patients about Fertility Preservation

Background. The aim of this study was to obtain feedback from, and reach consensus among different experts who are or have been involved in information provision about FP, regarding the (procedure of) information provision about Fertility Preservation (FP) and use of a web-based decision aid (DA) about FP to create optimal conditions for the implementation of the DA-website, as we prepare to implement a DA about FP in the Netherlands. Material and methods. A two round Delphi study in which experts (patients and clinicians) rated their (dis) agreement with a list of statements (Rounds 1, 2), and additional online forum to discuss dissensus (Round 3). We assessed opinions about FP, web-based DAs, and about the procedure of informing patients. Answer categories ranged from 1 (totally disagree) to 5 (totally agree). Consensus was considered significant when at least 80% of the experts scored either the lowest or the highest two categories. Results. Experts reached rapid consensus on all five statements about the use of a DA (5/5; 100%), and all eight statements about which patients should be offered information about FP (8/8; 100%). However opinions about FP (4/11 statements; 36%), and procedural aspects such as who should inform the patient (6/10 statements; 60%) and when (3/10 statements; 30%) remained for discussion in round 3. In the online discussion some level of agreement was reached for these statements after all. Conclusion. It was deemed important that FP options exist. Every eligible patient should receive at least some (general) information about FP, soon after diagnosis. Detailed information should be provided by a fertility expert at a later moment. Exact timing and amount of information should be adjusted to patient's needs and situational context. A DA-website can offer a fair contribution to this.
