The Medical Birth Register is updated yearly. The main results are published biannually and in specific articles. Integration Registers similar to the Danish one are being compiled in other Nordic countries. There is close cooperation. The Clearinghouse was founded in 1974 as a means of rapid communication among the various malformation monitoring or surveillance programmes around the world.
Extensive information is exchanged and data are compared.
Abortions and malformations have not been analysed sufficiently in relation to work hazards. The two registers can create important statistical data for such studies. The user may print out data or a copy it to a computer disc, provided that such copy is for his own personal use or internal corporate use only.
