  • Data collection arrangements

    The CPRD database contains coded and anonymised data from GP practices capturing information on demographic characteristics, diagnoses and symptoms, prescriptions, vaccination history, laboratory tests, referrals to hospital and specialist care. No identifiable patient information (i.e., name, address, exact date of birth or medical notes) is collected. CPRD also provides access to securely linked healthcare datasets including hospital care and death registry data. The data linkage process is carried out by NHS Digital, the body in England able to receive identifiable information, to ensure that CPRD only receives and provides anonymised data.
    As of October 2021, over 2,000 GP practices across the UK, equating to 1 in every 4 GP practices, have chosen to share their anonymised patient data with CPRD for vital public health research. The CPRD database continues to expand as more GP practices elect to share their data with CPRD. In 2021 the Database encompasses data on over 60 million patients, of whom 16 million are registered at GP practices currently contributing data to CPRD on a daily basis.
