Data Standards Change Notices


A Data Standards Change Notice (DSCN) is a mandate to NHS and partner organisations and system suppliers to ensure that they are able to support a new or changed data standard. 

DSCNs are issued to the Service once new or changed data standards, sponsored by the Welsh Government Department of Health, Social Service & Children, are approved by the Welsh Information Standards Board (WISB).
