Clinical Practice Research Datalink (CPRD)
Clinical Practice Research Datalink (CPRD) is a UK Government research service, jointly supported by the National Institute for Health Research and the Medicines and Healthcare products Regulatory Agency. CPRD provides access to anonymised NHS data for observational and interventional public health research.
Primary care data held by CPRD includes over 20 million patient lives, of which 5 million are currently registered patients, representative of the UK population with respect to age, gender and ethnicity.
For over 30 years, hundreds of GP practices across the UK have contributed information in patient records to the CPRD to support medical research to improve patient and public health including:
- Answering important questions about what causes illness and how to prevent and treat it
- Monitoring the safety of vaccines and medicines
- Understanding possible side effects of treatments in patients
Only anonymised patient data is provided to researchers.
