SNOMED CT UK Query Table and History Substitution Table

Releases of this item contain 2 related derivatives of the SNOMED CT UK Edition to aid the processing of inactive content within systems and data repositories.

The History Substitution Table provides a single table identifying valid substitutions for concepts that are now inactive, along with metadata about that substitution; it is computed using the historical relationships within the main SNOMED CT release but presented as a simpler look-up table.

The Query Table is an extension to a normal SNOMED CT transitive closure table, taking into account the History Substitutions Table and other data. It provides a mechanism to achieve optimal data retrieval, regardless of inactive and active concept status in data or query definitions. The Query Table is recommended as a mechanism for ensuring inactive content is still returned in searches, and is specifically recommended by the Joint GP IT Committee for use in primary care systems.

Status: Supported
