Documentation
The CPRD Primary Care and Linked Data OMOP CDM database contains longitudinal routinely-collected health records (EHR data) from UK primary care practices, and hospital episode data provided by NHS England. The data has been transformed into a common format (data model) using an open community data standard and structure from the OHDSI standardised vocabularies. The approach allows organisation, standardisation and common representation of medical terms and variables that have been obtained from various clinical data sources. Access to anonymised data from CPRD is subject to a full licence agreement containing detailed terms and conditions of use. Anonymised patient datasets can be extracted for researchers against specific study specifications, following protocol approval.
