Observational Data

Increase Font Size Decrease Font Size

The CPRD offers unique opportunities for health researchers to draw on the power of large multi-linked observational datasets on a previously unprecedented scale. Access is provided to support clinical innovation, strengthen evidence of effectiveness and improve health outcomes as well as safeguard public health and enable health services research.

Observational data are currently available from a range of primary and secondary care settings, including disease registries, linked to key demographic and socioeconomic datasets. Data are provided online and via study specific data sets depending on the requirements of the researchers.
For more information click on access and linkage options.

It is the vision of the CPRD to optimise research outputs by maximally linking person level data from different healthcare domains. Whilst the CPRD primarily focuses on health and social care, data from external domains will be considered for new linkages where the advantage for research is clear. All linkages are subject to required approvals. If you would like us to investigate use of data from a different domain, contact CPRD Enquiries for more information ().

There will be an incremental approach to increasing the population cover of, particularly, Primary Care data and the introduction of the extended on-line data.
