The national data opt-out publication provides statistics on the volumes of national data opt-outs. The national data opt-out was introduced on 25 May 2018 following recommendations from the National Data Guardian and indicates that a patient does not want their confidential patient information to be shared for purposes beyond their individual care across the health and care system in England. The service allows individuals to set a national data opt-out or reverse a previously set opt-out. It replaced the previous type 2 opt-outs which patients registered via their GP Practice. Previous type 2 opt-outs have been converted to national data opt-outs.

Please note this publication is no longer released monthly. Instead it will be released annually or when the national opt-out rate changes by more than 0.1 per cent.
