Component Inactivation
When components of SNOMED CT are deemed out of scope or inappropriate for a particular SNOMED CT Edition, it is the responsibility of SNOMED CT authors to inactivate the component, specify an appropriate reason for inactivation and in some cases, identify proper replacements.
Practical requirements for a high quality inactivation process
- Authors of SNOMED CT content need to understand the available reasons for inactivation and be able to apply these consistently.
- Authors of SNOMED CT need to be able to prioritize inactivation values consistently in cases where multiple reasons occur.
- Authors need to identify proper replacements for specific cases of inactivation
Identifying Impact of Inactivation
Resolving Inactivation Issues
Developing services to identify inactivated components and their replacements
to identify inactivated components and their replacements which can be presented to end users and systems in real time Development of robust audit trails which ensure a complete concept history which may include textual supporting information Development of appropriate notification to end users of clinical records where concept inactivation may impact the meaning of existing records | ||
