Type 1 opt-out: medical records held at your GP practice

You can also tell your GP practice if you do not want your confidential patient information held in your GP medical record to be used for purposes other than your individual care. This is commonly called a type 1 opt-out. This opt-out request can only be recorded by your GP practice.

Type 2 opt-out: information held by NHS Digital

Previously you could tell your GP practice if you did not want us, NHS Digital, to share confidential patient information that we collect from across the health and care service for purposes other than your individual care. This was called a type 2 opt-out.

The type 2 opt-out was replaced by the national data opt-out. Type 2 opt-outs recorded on or before 11 October 2018 have been automatically converted to national data opt-outs.
