The Clinical Practice Research Datalink (CPRD) is the world's best database of anonymised longitudinal medical records from primary care. Containing comprehensive observational data from clinical practice, it is a valuable tool for academic research in a broad range of areas including clinical epidemiology, disease patterns, disease management, outcomes research, and drug utilisation. CPRD is a highly valued resource by pharma and biotech companies because of its high quality longitudinal person specific records that enable drug safety, outcomes and economic research. The ability to link data from hospital or disease registers adds to this capability.
