- What is Subset?
- A subset is a set of members all of which are members of another set (from set theory in mathematics), but generally, in clinical terminologies, it is a set of concepts or terms taken from a larger set of terms or concepts
- Types of Subsets
Subsets can be grouped into categories. The categories listed below are different ways of looking at subsets and are not mutually exclusive:
- Data capture vs Data retrieval subsets
- Physician specialty vs Electronic health system-specific field subset
- Intensional vs Extensional subsets SNOMED CT Example
- Concept/Code Subsets vs Clinician Descriptions Subsets
- These subsets types can be created by many methods, but here are a few commonly used
- Manual inclusion, using search and browse methods
- An existing subset, used as a starting point for further manual inclusion and update
- Lexical queries, to identify candidate members, followed by manual verification and update
- Hierarchical queries, to identify descendants of a given concept (e.g. descendants of <73211009 |diabetes mellitus|)
- Attribute queries, to identify concepts with a specific attribute value (e.g. disorders with a finding site of 80891009 |heart structure|
- SNOMED CT queries, using the SNOMED CT Expression Constraint or Query languages, which offer additional query functionality.

- Additional Terminology Subsets (what are they and CHI role)
Infoway supports organizations and Jurisdictions to publish their Terminology Artefacts on the Terminology Gateway. Once published, jurisdictions are requested to maintain their subsets as part of the Infoway Maintenance Cycle. These subsets may be leveraged by other organizations and jurisdictions to support interoperability EHR solutions in their organization or jurisdiction. The shared subsets would be vendor-neutral, decrease the cost of creating and maintaining a new subset and support the EHR Blueprint.
