Join the growing network of GP practices contributing to CPRD

Trusted and government-backed


The Clinical Practice Research Datalink (CPRD) is a not-for-profit organisation, jointly funded by the National Institute for Health Research and the Medicines and Healthcare products Regulatory Agency, which has been providing anonymised healthcare records for public health research for over 25 years.

Hundreds of GP practices across the UK contribute anonymised patient data to CPRD. Data has been used in peer-reviewed research leading to improvements in drug safety and clinical guidelines, resulting in over 1,700 publications.

Joining CPRD is endorsed by the Royal College of GPs, the NIHR Clinical Research Network and NHS England.

Working with CPRD to increase the number of GPs contributing data is a commitment in NHS England’s 2017 research plan      .

How the data is used

Data is used for observational research to understand patient and public health outcomes and to develop evidence-based healthcare. Data is also used to support patient-consented clinical studies.

Some examples of how CPRD research benefits public health.

Benefits to GPs of joining CPRD

  • Anonymised primary care data from your practice will support vital public health research leading to advances in patient safety and delivery of care.
  • Your practice can take part in clinical studies – ranging from GP questionnaires to clinical trials - and earn extra income.
  • Your patients will have the opportunity to participate in clinical studies, demonstrating that your practice is at the forefront of evidence-based healthcare.
  • You can receive regular practice-level quality improvement feedback, helping you improve clinical outcomes for your patients.
  • Joining CPRD is a simple, one-off process. Data is then collected automatically with no burden to practice staff.

Safeguarding patient data

CPRD only receives and supplies anonymised patient data and complies with robust ethics, governance and security regulatory frameworks. Primary care data is linked  to other healthcare datasets by trusted third parties.

Data can only be supplied to bona fide researchers for public health research purposes. CPRD operates on a GP opt-in basis and individual patients have the right to opt out of their data being collected by CPRD for research.
