The National data opt-out is a service that allows patients to opt out of their confidential patient information being used for research and planning.
Your health records contain a type of data called confidential patient information. This data can be used to help with research and planning. However, you can choose to stop your confidential patient information being used for this. You can do this either by following the link or collecting a form from the surgery which once completed you will need to bring back to us.
