National Data opt-out
If you don’t want your data to be shared for purposes except for your own care, you can opt-out by registering a Type 1 Opt-out or a National Data Opt-out, or both. These opt-outs are different and they are explained further here https://digital.nhs.uk/data-and-information/data-collections-and-data-sets/data-collections/general-practice-data-for-planning-and-research/transparency-notice.
Your individual care will not be affected if you opt-out using either option.

As data controllers, GPs have fair processing responsibilities under the Data Protection Act and GDPR law 2018. This means ensuring that your personal confidential data (PCD) is handled in ways that are safe, transparent and what you would reasonably expect.
