Change Control/Definitions Liaison

Data Definitions and References

NHS National Services Scotland ISD Scotland & NHS National Services Scotland

Change Control Group/Definitions Liaison Group

Changes or enhancements to definitions follow a similar process of consultation. In the past there was a formal Definitions Liaison Group which met regularly, but consultations are now mainly virtual and are shared via email. If you do not already get this kind of communication from Data Advice then please contact

Changes to the SMR dataset go through a process of approval which involves consultation internally and externally culminating in an ISD Change Control meeting and a separate external Change Control meeting where representatives from the Health Boards are encouraged to attend. Usually such meetings only occur once a year - November and January respectively. There is also a fast track process that any change can follow if necessary.

The DLG Archive is a help-system that allows users to refer to definitional and data recording queries raised by NHS boards in NHSScotland between 1996 and 2010.

Such queries are usually discussed at the Change Control Group/Definitions Liaison Group at ISD. Any queries that have led to changes in data recording guidance, validation, or the initiation of a new project are published in the Definitions, Reference Files & Standards Bulletin (formerly QDV Newsletter).

Please note that the DLG Archive is available on the Data Dictionary Opens in new window.
