$395 / 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.

An Association reference set is a component reference set used to represent represents a set of unordered associations of a particular type between components.

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 Snapshot release contains the most recent version of every component released up to the time of the snapshot. The version of each component contained in a snapshot is the most recent version of that component at the release time. The ‘Snapshot’ release is useful for a simple installation but does not provide a history or retrospective view of the terminology. There are valid use cases for each Release Type. Each International release will incorporate all three of these Release Types, allowing users to choose the most appropriate format.

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.

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= true, the reference set member is part of the current version of the set, if active=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 the source component of the association.integerrequired : 1 level : Nominal
