Approved studies using CPRD Data

Access to CPRD data, including UK Primary Care Data, and linked data such as Hospital Episode Statistics, is subject to protocol approval via CPRD’s Research Data Governance (RDG) Process. Independent scientific and patient advice is provided by Expert Review Committees (ERCs) and the Central Advisory Committee (CAC). 

A summary of all approved protocols, including a lay and technical summary of the proposed research, is published three months after RDG approval. 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. 

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.
