Access to CPRD data is subject to protocol approval by an Independent Scientific Advisory Committee (ISAC). Approval is required if access to anonymised patient level data is being requested for research purposes.
This includes access to the following:
For further clarifications please contact the ISAC Secretariat at firstname.lastname@example.org
All protocols must be submitted to the ISAC Secretariat using the Protocol Application Form. Applicants should ensure that the latest version of the forms are used. Applications for data access will not be accepted in any other format. In addition, a brief curriculum vitae and conflict of interest statement for each researcher named on the application should be included using the template provided.

Some uses of data, such as conducting analyses for submissions to regulatory bodies, are exempt from ISAC review.
Analysis for regulatory bodies
In general, ISAC approval is required prior to release of CPRD data to any third party, so as to ensure that the standard of studies carried out using CPRD data is maintained. However, there are some types of aggregate data necessary for regulatory work that is suitable for exemption from this requirement, such as:
- Counts of patients receiving prescriptions for a certain substance;
- Counts of prescriptions for a certain substance / substances;
- Distribution of number of prescriptions per patient (mean, median, minimum, maximum, interquartile range etc…);
- Distribution of prescription duration;
- Distribution of patient time at risk;
- Counts of patients with a particular clinical event.
