A Data Dictionary Change Notice (DDCN) is a notice of a change to the NHS Data Model and Dictionary which is not appropriate for Data Alliance Partnership Board publication as an Information Standards Notice, as the change does not relate to an individual standard.

The Data Dictionary Change Notices can be downloaded from: Data Dictionary Change Notices.

Further information on Data Dictionary Change Notices can be found on the NHS Data Model and Dictionary Service part of the NHS England website at: Policies: Data Dictionary Change Notice guidance.
