The National Data Opt-out (NDOO) is a central registry of patients who do not want their medical information to be used by any organisations for research or future planning.

Patients have to register at Registration for opt out. This will ensure that their data is removed from any searches carried out centrally before patient data is shared to be used for research or planning purposes.
