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. COVID-19 research protocols are being fast-tracked and all approved summaries are published within 72 hours to ensure transparency and to help avoid unnecessary duplication.

The table below includes all ISAC-approved protocols submitted to CPRD from 1st July 2015. Protocols below are listed in order of date of approval. Please click on the study title for more details.

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