SNOMED CT Delta Module Dependency Reference Set

$79 / year

This dataset describes the Release File structure of SNOMED CT, referred to as Release Format 2 (RF2). The US Edition of SNOMED CT is the official source of SNOMED CT for use in US healthcare systems. The US Edition is a standalone release that combines the content of both the US Extension and the International release of SNOMED CT.

The Module dependency reference set is used to represent dependencies between modules, taking account of module versioning.

Complexity

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.

In addition to 363 new concepts specific for the US, the March 2018 SNOMED CT US Edition also contains all of the content from the January 2018 SNOMED CT International Edition. Approximately 200 requests for terminology additions and updates were submitted via the US Content Request System (US CRS) to support US clinical health information data exchange.

NameDescriptionTypeConstraints
Reference_Set_Member_IdA 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.stringrequired : 1
Effective_DateThe inclusive date at which this version of the identified reference set member became the current version.daterequired : 1
Is_ActiveThe state of the identified reference set member as at the specified Effective_Date. If active= 1 (true) the reference set member is part of the current version of the set, if active=0 (false) the reference set member is not part of the current version of the set.booleanrequired : 1
Module_IdIdentifies the SNOMED CT module that contains this reference set member as at the specified Effective_Date.integerrequired : 1 level : Nominal
Refset_IdIdentifies the reference set to which this reference set member belongs.integerrequired : 1 level : Nominal
Referenced_Component_IdThe identifier of a target module on which the dependent module (identified by Module_Id) depends.integerrequired : 1 level : Nominal
Source_Effective_DateThe effective date of the dependent source module (identified by Module_Id). This specifies a version of that module, consisting of all components that have the same Module_Id as this refset member in their states as at the specified Target_Effective_Date.daterequired : 1
Target_Effective_DateThe effective date of the target module required to satisfy the dependency (identified by Referenced_Component_Id). This specifies a version of that module, consisting of all components with the moduleId specified by Referenced_Component_Id in their states as at the specified Target_Effective_Datedaterequired : 1
