CPRD (Clinical Practice Research Datalink)

CPRD (Clinical Practice Research Datalink) is a research-ready dataset of UK primary care health records, with available linkage to other health-related data. The dataset includes 60 million patients representative of the UK population, of which 18 million are currently registered, and 25 per cent have at least 20 years of follow-up. CEG has secured a Multi Study Licence that gives Queen Mary researchers access to CPRD data at a reduced cost. Barts Charity will support the licence until 2027 as part of the Precision Health: Population Health Data Science research programme, jointly led by CEG and Barts Cancer Institute. 

Who can access the Multi Study Licence? 

Anyone with a substantive post at Queen Mary University of London and an approved CPRD project is eligible to access CPRD data via the Queen Mary Multi Study Licence. 

Included in the licence

The Multi Study Licence provides access to:

• CPRD Aurum (from GP practices using EMIS)
• CPRD Gold (from GP practices using Vision)

Plus linked data from:

• Hospital Episode Statistics Admitted Patient Care (HES APC)
• Small area level data (Index of Multiple Deprivation, Townsend Deprivation Index, Carstairs Index, Rural-Urban Classification)

Other linked data

Other than those mentioned above, linked datasets are not included in the Multi Study Licence. But CPRD can provide other linked data for additional cost, including cause of death, COVID-19, cancer, hospital outpatients, A&E and diagnostic imaging. Researchers wishing to use linked datasets not included in the Multi Study Licence will need to pay CPRD directly to access them: cprd.com/pricing.
