Influence de la formation des echographistes sur le dépistage des cardiopathies congénitales (12 ans d'étude dans la population générale)

Abstract

Objective: Multidisciplinary prenatal diagnosis centers were created in France in 1998 and offer an opportunity of training to ultrasonographers. We aimed to measure the impact of their creation on the prenatal detection rates of congenital heart diseases (CHD).Methods: We analyzed the sensitivity of the screening performed by first level ultrasonographers (FLU) between 1994 and 2006 by comparing CHD prenatal diagnoses and CHD observed after birth in Angers universitary hospital. Two groups of FLU were compared (those attending the training and a control group of those who didn t). The evolution of these 2 groups detection rates was analyzed on two periods of 6 years (1994-1999 & 2000-2006) for significant CHD.Results: Of 947 CHD, 438 (46%) were detected prenatally. The control group sensitivity was 16% versus 37% for the FLU attending the training course. Concerning significant CHD, the control group didn t improve its sensitivity between the two periods whereas the other did (54% vs 75%, p<0.05).Conclusion : this study quantifies the beneficial effect of multidisciplinary prenatal diagnosis centers, not only for their primary purpose, management of pathological pregnancies or threatened fetuses, but also as learning centers which help FLU to improve their practice.ANGERS-BU Médecine-Pharmacie (490072105) / SudocPARIS-BIUM (751062103) / SudocSudocFranceF
