hierarchy tag

A parenthetical notation at the end of a fully specified name indicating the relevant domain.

Notes

• The purpose of hierarchy tags is to disambiguate concepts that contain the same commonly used words or phrases.

Examples

• 55903007 | Acute atrophy (morphologic abnormality)| with the hierarchy tag , morphologic abnormality in the body structure domain

• 89305009 | Abdominal paracentesis (procedure)| with the hierarchy tag , procedure

• Semantic tag

An HL7 project that developed the "HL7 Version 3 Implementation Guide: Using SNOMED CT in HL7 Version 3" as a Draft Standard for Trial Use (DSTU).

• The guide is an the HL7 Version 3 draft standard for achieving semantic interoperability to communicate clinical information represented by SNOMED CT concepts.

• TermInfo

healthcare professional

A person who provides health care services based on formally recognized training, experience and qualifications.

Notes

• This general definition is used in SNOMED International documentation. However, a more specific definition may apply in individual countries and organizations.

human readable concept model

A rendering of the machine readable concept model rules designed to be included in guidance documents.

Notes

• The human readable concept model is generated by processing the machine readable concept model to ensure that it accurately reflects the rules.

• The human readable concept model is presented in tables that organize the information from the perspective of concept model domains and attributes. These tables include:

  • Expression constraint language representations of domains and ranges;

  • Constraints on attribute cardinality and attribute in group cardinality.

• Selected human readable concept model tables are included in the SNOMED CT Editorial Guide and will also appear where relevant in other SNOMED CT guides.

• HRCM

healthcare episode

A grouping of one or more healthcare encounters, in which a subject of care receives health care services for one or more health problems or disorders from a healthcare provider.

Notes

• A healthcare episode may be part of another healthcare episode. For example, a healthcare episode may include several outpatient encounters and one or more inpatient episodes.

• This general definition applies to SNOMED International documentation but it should be interpreted taking account of more specific national or organizational definitions of healthcare episode. This is particularly important as these definitions may have specific legal or financial implications.

This is an abbreviation for Common Terminology Services 2.

An application programming interface (API) specification of the basic functional requirements used to query and access terminological content.

• CTS2 * Is an abbreviation for Common Terminology Services 2. * Is used by healthcare software implementers. * Defines the functional requirements of a set of service interfaces to allow the representation, access, and maintenance of terminology content either locally, or across a federation of terminology services nodes._ _ * Is specified as an API, rather than a set of data structures. This enables a wide range of terminological content to be integrated within a common framework, without the need for significant migration or revision. * Was developed from the original HL7 CTS specification and is now a joint initiative between HL7 and the .

• HL7 V3 RIM

This is an abbreviation for Health Level 7 Version 3.

A standard for communication of electronic health information developed by HL7.

• Version 3 is based on a formal development framework in which the communication structures are derived as refinements from a Reference Information Model (HL7 V3 RIM).

• Health Level 7 is not-for-profit and ANSI-accredited.

An arrangement of nodes in which each node is linked to one or more parent nodes.

• In SNOMED CT the nodes are concepts linked to their more general parent concepts by relationships.

• Concepts with the most general meanings are presented at the top of the hierarchy , with the concepts linked to them at the level beneath, and so on. At each level down, the meanings of the concepts are increasingly more specific or specialized.

• HL7 V3

A reference set that provides information about concepts or descriptions that have been inactivated.

• There are two types of historical reference sets :

  • Inactivation Reference Sets which indicate the reason for inactivation of a particular component.

  • Historical Association Reference Sets which associate inactive concepts with one or more active concepts that represent the same, similar or a possible meaning of an inactive concept.
