National Data Opt Out

The national data opt-out policy was introduced on 25 May 2018, following recommendations from Dame Fiona Caldicott in the 'Review of data security, consent and opt-outs'. National data opt-out is a service which allows the public to opt out of their confidential information being used for purposes beyond their individual care and treatment. This review aimed to ensure the public can make choices on how their data is used for research and planning purposes.

The information collected about you when you use these services can also be used and provided to other organisations for purposes beyond your individual care, for instance to help with:

  • improving the quality and standards of care provided;
  • research into the development of new treatments;
  • preventing illness and diseases;
  • monitoring safety;
  • planning services.

This may only take place when there is a clear legal basis to use this information. All of these uses help to provide better health and care for you, your family and future generations. Confidential patient information about your health and care is only used like this where allowed by law.

Most of the time, anonymised data is used for research and planning so that you cannot be identified, in which case your confidential patient information is not needed.

You have a choice about whether you want your confidential patient information to be used in this way. If you are happy with this use of information you do not need to do anything. If you do choose to opt out your confidential patient information will still be used to support your individual care.
