Description
SNOMED CT (SNOMED Clinical Terminology) provides a common language that assists with the electronic exchange of clinical health information. It enables a consistent way of indexing, storing, retrieving, and aggregating clinical data across specialties and sites of care. SNOMED CT Can be mapped to other coding systems, such as ICD-10, which helps facilitate semantic interoperability.
A Delta release contains only those component versions created, inactivated or changed since the previous release. The ‘Delta’ release is much smaller than a ‘Full’ release and is ideal for updating a ‘Full’ release of the previous version. Adding a ‘Delta’ release to the previous version’s ‘Full’ release will update the installation to a ‘Full’ release of the current Version.

Data Fields
Name | Description | Type | Constraints |
---|---|---|---|
Reference_Set_Member_Id | A field, uniquely identifying this reference set member. Different versions of a reference set member share the same id but have different Effective_Date. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time. | string | required : 1 |
Effective_Date | The inclusive date at which this version of the identified reference set member became the current version. | date | required : 1 |
Is_Active | The state of the identified reference set member as at the specified Effective_Date. If "true" the reference set member is part of the current version of the set, if "false" the reference set member is not part of the current version of the set. | boolean | required : 1 |
Module_Id | Identifies the SNOMED CT module that contains this reference set member as at the specified Effective_Date. | integer | level : Nominalrequired : 1 |
Refset_Id | Identifies the reference set to which this reference set member belongs. | integer | level : Nominalrequired : 1 |
Referenced_Component_Id | A reference to the SNOMED CT component to be included in the reference set. | integer | level : Nominalrequired : 1 |
