CPRD ISAC Applications Guidance

The Guidance on the content of CPRD ISAC applications has been updated and can be found under the ISAC section of our website. A PDF copy is also available for download. Changes and additions to the previous guidance document are highlighted - we would urge all applicants including regular CPRD users to read the updates.

ISAC audit of publications

The ISAC will be undertaking an audit of all publications in 2013 which resulted from studies using CPRD data. The primary purpose of the audit is for ISAC to better understand the level of concordance between approved protocols and the resultant studies. The ISAC guidance on amendments to approved protocols is available under the ISAC section of our website.
