Register of Approved Data Releases

Our data release register is a record of all the data we have shared with other organisations.

NHS Digital's Release Register is published every quarter and provides information on data released under Data Sharing Agreements. It covers activity for the preceding three months plus any amendments/additions to older releases.

It lists organisations by name, the type of data released, the legal basis for release, the purpose for which the data was provided and an indication whether patient opt-outs were applied to the dataset before release. In the main, the Release Register includes a line per physical file disseminated.

Our patient opt-out policy explains when opt-outs do and do not apply in more detail.

When reviewing the Release Register the application of opt-outs may, at face value, appear inconsistent because the application is determined by considering the combination of data items being released. For example, whether the data are classed as confidential patient information, and the legal basis under which those data are released. Certain specific legal bases are exempt from having opt-outs applied.

Please review the 'Read me' tab at the front of the Release Register for details of other changes.
