Outdated | REPLACED_BY POSSIBLY_REPLACED_BY No suitable replacement identified | The inactivation reason “Outdated Concept” explicitly states that the inactivated concept (A) is an outdated concept that is no longer considered to be clinically acceptable or semantically interoperable internationally. It is possible that the original meaning of the outdated concept could be “REPLACED_BY” concept (B) that is semantically similar to or more general than the inactivated concept for the purposes of data healing and analysis of historical data. However, in some circumstances, there will be no suitable replacement concept and therefore no historical association is provided. |
- Is the concept outdated?
Careful research is needed to clearly differentiate between a true duplicate, where there is semantic equivalence between the two concepts, and where there is a true evolution in the understanding of the concept, and therefore, an evolution in the meaning, that warrants a more appropriate “REPLACED_BY” target concept.

| - Where there has been an update to a disorder classification, a substance or organism originally believed to be a single entity has, following further study been reclassified as 2 or more substances or organisms
- Use Outdated Concept with a historical association to 2 or more POSSIBLY_REPLACED_BY target concepts.
- It is also possible that outdated clinical concepts simply fall into disuse without any appropriate replacement, and therefore no historical association should be provided.
- Simple renaming of drugs or organisms where the meaning is unchanged should be dealt with by updating the FSN only using ‘Outdated component’ as the association type on the inactivated FSN description.
