Summary

Objective:
To analyze an efficiency of prenatal diagnostics of selected types of birth defects in the Czech Republic in 1994 – 2006 period.

Design:
A retrospective epidemiological study and a prenatal diagnostics efficiency analysis.

Setting:
Department of Medical Genetics, Thomayer’s University Hospital, Prague.

Chair of Medical Genetics, Postgraduate Medical Institute, Prague, Czech Republic.

Methods:
Data were collected from National Birth Defects Register (Institute of Health Information and Statistics). Incidences of selected types of birth defects were analyzed.

Results:
In 1994 – 2006, totally 1 132 567 children were born in the Czech Republic, out of which more than 42 000 with a birth defect. A mean incidence was 339 per 10 000 live births with a maximum of 414.58 per 10 000 in 2003. In the same time period, 6113 cases of birth defect prenatal diagnostics (49.3 per 10 000 live biths) were reported.

Conclusion:
In a comparison of 1980 – 1993 and 1994 – 2006 periods, a significant increase of prenatal diagnostics efficiency was recorded.
