• Structure and Content Guide:
  • This part of the guide provides reference material on the technical design of glossary-ref

    . These design features provide the foundation for the services described in subsequent parts of the guide.

    content.
• Editorial Guide:
  • This part of the guide describes the ways in which technical design of glossary-ref

    Gloss
    t SNOMED

    CT

    is populated with content. The glossary-ref

    Gloss
    t Concept

    Model

    specifies the main hierarchies in which glossary-ref

    Gloss
    t concepts

    are arranged and the types of the glossary-ref

    Gloss
    t relationships

    that are permitted between them.
  • This glossary-ref

    Gloss
    t Concept

    Model

    is directly relevant to implementation because it determines the types of clinical ideas that can be expressed using glossary-ref

    Gloss
    t SNOMED

    CT

    and the ways in which these ideas can be refined to represent more detailed information.
• Terminology Services Guide :
  • This part of the guide describes the types of services required to access and make use of glossary-ref

    Gloss
    t SNOMED

    CT

    . It also provides practical advice on effective ways to deliver these services based on practice experience.
  • These services include: importing distribution files, determining the status and properties of selected components, searching for glossary-ref

    , navigating hierarchies, testing and using glossary-ref

    Gloss

    between glossary-ref

  • As part of the consideration of storage, communication and retrieval, this part of the guide also discusses the integration of the terminology with a well-designed information model. It is now widely recognized that this is crucial element in design and development of a glossary-ref

• Change Management Guide:
  • This part of the guide addresses requirements that arise from changes to the content, structure and use of glossary-ref

    Gloss

    .
  • The first significant change management challenge relates to glossary-ref

    Gloss
    t migration

    from other coding schemes or from a less structured electronic record system. Decisions must be made about retaining or converting records, queries and protocols originally created using a terminology other than glossary-ref

    Gloss
    t SNOMED

    CT

    .
  • Each release of glossary-ref

    Gloss
    t SNOMED

    CT

    introduces some changes to content. From time to time there will also be changes designed to increase the expressivity of the glossary-ref

    Gloss
    t Concept

    Model

    . Occasionally there may also be additional technical artifacts or specification developed to meet emerging requirements.
  • As systems evolve and as the content and structure of glossary-ref

    Gloss

    CT

    are enhanced there is a continuing requirement to address to manage changes smoothly and without loss of information or functionality.
• Extension Services Guide:
  • This part of the guide describes additional services which some advanced users or implementers may require to allow them to create or maintain glossary-ref

    Gloss
    t Extensions

    for use in a particular country, organization or specialty.
  • The most common of these requirements will be to support the creation and maintenance of specialized glossary-ref
