Project Description

Clinical Practice Research Datalink (CPRD)

The DSRU has a licence to access to CPRD, the NHS observational data service, based in the UK. Our epidemiologists have experience of working with CPRD data and will be pleased to discuss a potential CPRD study with no commitment  – contact us.

CPRD provides unique opportunities for researchers to harness the power of large multi-linked observational datasets, while protecting patient confidentiality:

  • all data are anonymised
  • CPRD collects fully-coded patient electronic health records from GP practices across the UK
  • over 5 million currently registered and active patients
  • representative of the UK population with respect to age, gender and ethnicity
  • linkage to secondary care and registry data available

The DSRU team uses CPRD data in a variety of study designs, to investigate various research questions in pharmacovigilance and pharmacoepidemiology, including:

  • Studies to fulfill post-authorisation regulatory requirements (PASS studies)
  • Pre-authorisation applications
  • Drug utilisation studies
  • Safety studies investigating exposures and outcomes of interest over time
  • We were approached by a company which requested a CPRD study to support extension of a product licence to a new age group of patients.
  • CPRD was chosen because it reflects real-world use from electronic medical records and can provide information on use in groups which are not covered by the current licence.
  • Real-world data is becoming used more frequently to support licence extension applications and has several advantages over clinical trials, including lower costs.
  • The DSRU was able to advise that regulators frequently accept this type of study to support license extension applications.
  • A CPRD study was proposed to provide data on safety and utilisation of the medicinal product in an age group not covered by the current licence.
  • The study population comprised patients who received the product in the primary care setting in the UK within the new age group of interest.
  • Variables collected included age, sex, daily dose, duration of treatment, concomitant medications, prior medications, medical history, safety events, weight at baseline, test results at baseline and 3 months after starting treatment.
  • The DSRU team conducted the study on the CPRD GP Online Data (GOLD) database in the UK.
  • The study was completed within 8 weeks, including data extraction, preparation, analysis and production of final report.
  • We were approached by a company which requested a CPRD study to support the application for a variation of a product licence to add a new therapeutic indication for use in a specific age group of patients.
  • The DSRU advised that regulators frequently accept this type of study to support license variation applications.
  • A CPRD study was proposed to provide data on demographic, safety and utilisation of the medicinal product within this age group.
  • The study population comprised patients who received the product in the primary care setting in the UK.
  • Variables collected included age, sex, daily dose, duration of treatment, concomitant medications, prior medications, medical history, safety events, weight at baseline.
  • The DSRU team conducted the study on the CPRD GP Online Data (GOLD) database in the UK.
  • The study was completed within 8 weeks, including data extraction, preparation, analysis and production of final report.

The DSRU is in good company: CPRD data are used worldwide by regulators, academic researchers and the life science industry for observational and interventional public health studies. Over 1,800 studies have been published to date.
