title: Follow-up validation study of the Victorian Congenital Malformations Register.
abstract: OBJECTIVE
  To determine whether there has been an improvement in ascertainment of malformations in the Victorian Congenital Malformations Register (VCMR).
  
  
  METHODS
  The medical records of 500 children under 4 years of age admitted consecutively to two paediatric teaching hospitals in Victoria in 1992 were viewed to determine whether these cases had been notified to the Register.
  
  
  RESULTS
  Over three-quarters of the defects recorded had been notified to VCMR. There was 100% ascertainment of chromosomal anomalies and a high proportion of major structural malformations were notified.
  
  
  CONCLUSIONS
  This study repeats the validation study completed in 1986 and shows marked improvement in ascertainment of malformations in the VCMR by 1992.
