Registration of congenital anomalies in Switzerland by EUROCAT.

Abstract

Since 1988 the epidemiological surveillance of congenital anomalies (malformations, chromosomal aberrations, metabolic diseases, hereditary diseases, neurosensorial defects, etc.) is carried out by the Swiss registry of EUROCAT (European Registry of Congenital Anomalies and Twins). Several Swiss cantons collaborate through their own local registry, transmitting data to the central registry in Lausanne. We present the main objectives and methods of registration and give the global prevalence rates for the main malformations for 1996 and the period 1993-1996.
