CPRD GOLD Source file January 2022

The source data are provided to organisations that hold CPRD multi-study licences to enable researchers to ascertain which patients are eligible for linkage and to clarify the coverage periods for each data source. The linkage eligibility file (linkage_eligibility.txt) only includes patients from practices that have consented to take part in the linkage process. The file contains flags to indicate whether the patient is eligible for each individual linked data source. Some patients will not be eligible for any of the linked data sources, whereas others may be eligible for some/all of them. These data are provided so that users can determine the appropriate population to include in their study. The linkage coverage file (linkage_coverage.txt) indicates the start and end of coverage for each individual linked data source.
Access to source data is available to nominated users only. Further information is available at https://www.cprd.com/linked-data.
The November 2024 source file reflects patients at practices who were contributing to CPRD in January 2022
