The Vision
To enhance the health of human-kind by facilitating better health information management
To contribute to improved delivery of care by clinical and social care professions
To facilitate the accurate sharing of clinical and related health information, and the semantic interoperability of health records

Just some of the challenges ...
What is the patient’s problem list? Is a new drug safe to prescribe? What are the latest test results? Is recommended preventive care due? How long are patients waiting? Are there emerging patterns in infectious disease outbreaks?

Achieving the Vision will require
A globally co-ordinated effort Agreement on a core Terminology for recording and
sharing of health information Pooling of resources to share the costs and benefits
relating to the development and maintenance of the Terminology Products
Consistent promotion of the uptake and correct use of the Terminology
Active harmonization activity with other SDOs

What is SNOMED CT?
Systematized Nomenclature of Medicine Clinical Terms® (SNOMED CT)
A comprehensive clinical terminology covering diseases, clinical findings, and procedures
Represents the meaning of concepts using formal definitions Helps to structure and computerize health records allowing for a
consistent way of indexing, storing, retrieving and aggregating clinical data

How big is SNOMED CT?
More than 310,000 concept codes About 800,000 active terms (descriptions) More than 1.3 million active defining relationships
Scale is a major issue in developing, using and maintaining the terminology … and we expect growth in use, in localization, in translation, etc.

OHT Charter Project: SNOMED CT Tooling
![Page 12: Working Together to Advance Terminology Tooling Presentation to OHT Board, Birmingham Jennifer Zelmer & Karen Gibson.](https://reader030.fdocuments.in/reader030/viewer/2022032605/56649e725503460f94b71d51/html5/thumbnails/12.jpg)
SNOMED CT Tooling Project
Goal: Provide 2nd generation tools to develop, maintain, promote and enable the uptake and correct use of SNOMED CT in health systems around the world Enable fast and efficient development of SNOMED CT content Provide tools to support uptake and implementation Provide tools to facilitate and encourage the encoding of EHRs Encapsulate best practice in the implementation of SNOMED CT
Initial sponsors: IHTSDO, NEHTA, NHS First focus on SNOMED CT Modular Workbench

SNOMED CT Modular Workbench
Need for progress on a technical infrastructure to support the needs of IHTSDO and its members identified as a priority
Founded on technical architecture established by IHTSDO Technical Committee and more detailed specifications developed by Working Groups and others

Technical Architecture
![Page 15: Working Together to Advance Terminology Tooling Presentation to OHT Board, Birmingham Jennifer Zelmer & Karen Gibson.](https://reader030.fdocuments.in/reader030/viewer/2022032605/56649e725503460f94b71d51/html5/thumbnails/15.jpg)
Workbench Guiding Principles
Role based - an individual signs on in a particular role; Secure - the role is used by the various applications on the bench to
control user behaviour; Context aware - various applications “know” what objects the user is
working with and to what ends; Session aware – the ability to pick up exactly where one left off; Distributed - objects and the applications deployed both centrally
and locally Collaborative - the ability for authorised users to work together Published Interfaces – open architecture encouraged but will assess
offerings on their merits; expectation of published interfaces.
