UKTC SNOMED CT Query Table and History Substitution Table

This pack contains two related derivatives of the UK Edition of SNOMED CT 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 some 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 by UKTC 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.
