In this article we compare the recording of 30 common childhood conditions in two general practice databases of anonymised computerised medical records based on fundamentally different systems--the Doctor's Independent Network (DIN) database (Torex system) and the General Practice Research Database (GPRD) (In Practice Systems). Analysing the records of all children born 1990-1993 and followed for 5 years we found comparable results for most conditions, but differences between the hierarchical structures of the diagnostic coding systems (Read in DIN, OXMIS in GPRD) led to some differences between the databases. Practice variation was marked, but comparable between databases. Variation was greatest in conditions that are poorly defined clinically.
