Background: Combined trisomy 21 screening in the first trimester is now the reference method since 2007 HAS’s recommendations. Sonographists must obtain an identification number given by the local perinatality health network through a professional practice assessment procedure (PPA). The aim of this study was to evaluate screening practices in Basse Normandie, obstacles to getting an EPP, the self-evaluation habits acquired by practitioners who got an EPP, and the way patients are informed about screening modalities. Methods: This descriptive study was conducted from May to August 2016. A questionnaire was sent to 78 sonographers practicing in Normandy. Results: We analyzed 47 questionnaires. We found that 36 practitioners had an identification number, 35 of them adhered to the perinatal network of Basse Normandie, and 29 routinely evaluated Herman’s score during nuchal translucency evaluation. Furthermore, 11 practitioners, 8 of whom did not join the network, did not perform combined screening, justifying this with a lack of screening practice and lack of time to get an EPP. Information on screening procedures was provided in 76.6 percent of cases. Conclusion: Seven years after the 2009 decree, full adherence to EPP programs for optimal and consistent screening is not being achieved. Registration of practitioners to perinatal networks seems to favor the validation of EPP. This quality control approach encourages the practitioners to learn how to self-assess their subsequent exercise and, thereby, improve the quality of screening.
