The new BPA classification.

a supplement to ICD. This combined more detailed subdivision of diagnostic categories of interest to paediatricians with the elimination of diagnoses not commonly encountered in children. It was first available in 1962, known initially as the 'Cardiff classification'. The most recent extensive revision was published in 1979. In 1990, with a new revision of ICD in production (ICD-10), the International Paediatric Association requested that the BPA produce a paediatric adaptation of this. A project was, therefore, established to produce a new paediatric diagnostic classification for the 1990s and beyond.
