Eurocat

Eurocat (European Registration of Congenital Anomalies and Twins) is a European network of population-based registries for the epidemiologic surveillance of congenital anomalies. Established in 1979, Eurocat's main objective is to monitor the frequency of congenital anomalies, identify potential teratogens, and facilitate the study of causes of congenital anomalies. The network provides a crucial platform for the collection, analysis, and dissemination of data related to congenital anomalies across Europe, aiming to improve the health and well-being of pregnant women and their children.

Overview

Eurocat's mission is to provide high-quality data that can be used to prevent congenital anomalies and improve the diagnosis and treatment of these conditions. The network achieves this by:

• Monitoring trends in the prevalence of congenital anomalies.
• Identifying and investigating clusters of cases that may indicate new teratogens.
• Facilitating research into the causes of congenital anomalies.
• Supporting public health planning and the evaluation of preventive measures.

Membership

Eurocat comprises over 40 registries from more than 20 European countries, covering approximately one-third of the European birth population. Each registry collects data on live births, fetal deaths from 20 weeks of gestation, and terminations of pregnancy for fetal anomaly (TOPFA) after prenatal diagnosis. The data collected include detailed information on the type of anomaly, the gestational age at diagnosis, and potential risk factors.

Data Collection and Reporting

The data collected by Eurocat registries are standardized to ensure comparability across different countries and regions. This standardization includes the classification of congenital anomalies according to the International Classification of Diseases (ICD) and the use of specific Eurocat guidelines for case definition and classification.

Eurocat publishes annual reports and scientific papers that provide valuable insights into the epidemiology of congenital anomalies in Europe. These publications cover topics such as the prevalence of specific anomalies, temporal trends, geographic variations, and the impact of prenatal screening programs.

Research and Surveillance

Eurocat plays a key role in the surveillance of congenital anomalies in Europe. The network's research activities include:

• Investigating the causes of congenital anomalies, including genetic and environmental factors.
• Monitoring the impact of public health interventions, such as folic acid supplementation and vaccination programs.
• Studying the effects of exposure to potential teratogens, such as medications, alcohol, and environmental pollutants.

Public Health Implications

The work of Eurocat has significant public health implications. By monitoring the prevalence of congenital anomalies and identifying risk factors, Eurocat helps to inform public health policies and preventive strategies. This includes the promotion of preconception care, the optimization of prenatal screening programs, and the prevention of exposures to known teratogens.

Conclusion

Eurocat is an essential resource for the surveillance and research of congenital anomalies in Europe. Through its collaborative network of registries, Eurocat provides valuable data that contribute to the understanding of congenital anomalies, supports public health planning, and promotes the development of effective prevention strategies.
