Clinical Practice Research Datalink (CPRD)

Information in patient records is important for medical research to develop new treatments and test the safety of medicines. This practice supports medical research by sending some of the information from patient records to the Clinical Practice Research Datalink (CPRD).

CPRD is a Government organisation that provides anonymised patient data for research to improve patient and public health. You cannot be identified from the information sent to CPRD.


If you do not want anonymised information from your patient record to be used in research you can opt out.
