Further validation of information recorded on a general practitioner based computerized data resource in the united kingdom

Abstract

Abstract Studies have been carried out to evaluate the quality and completeness of the data recorded by GPs on VAMP computers for the purpose of carrying out drug safety studies. In an earlier study of 58 practices we found that clinical diagnoses reflecting the diagnoses noted in the consultant letters were present on the computer 87% of the time. We have now evaluated a further 35 practices. Agreement between the information in the consultant letter and that on the computer was present in 121 of 126 (96%) instances.
