Perceived barriers to elective single embryo transfer among IVF professionals: a national survey.

BACKGROUND After initial years of improvement, the multiple pregnancy rate after in vitro fertilization (IVF) in Europe now remains stable at 23% with single embryo transfer (SET) constituting 19% of all IVF cycles. Although elective SET prevents multiple pregnancies after IVF, couples and professionals apparently often decide to transfer more embryos. Previous qualitative research has identified factors that impede the use of elective SET. The aim of this study was to quantify those barriers among IVF professionals and to identify predictors of professionals' willingness to perform elective SET. METHODS A national survey among all Dutch IVF professionals quantified the barriers suggested by a previous qualitative study and assessed characteristics of the professionals and clinics. Multivariate analysis identified predictors related to the willingness of IVF professionals to perform elective SET. RESULTS In total, 107 professionals participated. The most frequently mentioned barriers to elective SET use were suboptimal success rates associated with cryopreservation (96%), not seeing twin pregnancies as a complication (79%) and lack of a SET protocol (78%). Two variables seem to predict the professionals' willingness to perform elective SET: university hospital of the initial fertility training (P< 0.01) and high scores of perceived barriers, e.g. professionals' attitudes and skills (P < 0.01). The explained variance of these two variables was 25%. CONCLUSIONS This study has identified the main barriers to elective SET use and predictors for willingness of professionals to perform elective SET. This insight into the decision-making process could be critical in terms of increasing the use of elective SET.
