Approved studies using CPRD Data

Applications to access CPRD data for observational research are reviewed by the Independent Scientific Advisory Committee (ISAC). Approval by ISAC is required for researchers to carry out their proposed studies.

A summary of all ISAC-approved protocols, including a lay and technical summary of the proposed research, is published three months after researchers have access to the data to begin their study.

The table below includes all ISAC-approved protocols submitted to CPRD from 1st July 2015. Searches can be carried out using applicant names, approval date or by using key words within the protocol title. Protocols below are listed in order of date of approval.

Peer-reviewed publications from research using CPRD data will be listed on our bibliography page
