1 An IHTSDO perspective for CIMI/SHN on information modeling and terminology activities David Markwell Head of Implementation & Education IHTSDO International Health Terminology Standards Development Organisation

2 Changes in IHTSDO  New CEO Don Sweete  “IHTSDO is open for business”  Key focus on Customers – the 26 Members of IHTSDO  More internal capacity reduced external dependencies

3 Implementation & Education  Staff  David Markwell  Linda Bird  Tom Seabury  SNOMED CT Implementation Advisor Scheme  Six people on 2014 SIA Scheme  Eleven people went through SIA scheme in 2012 & 2013  In 2014 main focus of Implementation & Education  Information models, analytics, terminology binding & expressions  Adoption, adaption and sharing of subsets  Represented as Simple Refsets  Need for descriptive data about sharable resources  Online education  Presentations and skills assessments

4 Useful EHR systems don’t just display raw data, they also deliver derived knowledge about the current situation … but, a chess board view derived from that record of moves makes the current situation understandable 1. d4 Nf6 2. c4 g6 3.

5 Geographic knowledge linkage  A map, a satellite view, crime statistics, photographs, local restaurants

6 Linked knowledge in action  Longitude and latitude provide a common reference model for geographic information that we now take for granted Journey log Drive times InferenceInference Road conditions KnowledgeKnowledge Route advice and local information DrivingDriving Route selection Latitude & Longitude Satellite mapping

8 Recognising interdependencies  Practical consequences of interdependency between terminology and structural information models are often underestimated  Information models cannot be terminology neutral  SNOMED CT implementation is dependent on tight integration with standard information models  Developers of clinical terminologies and clinical information models should adopt policies that facilitate ‘dependency aware evolution’ of their contributions 8 IHTSDO Concept Model Special Interest Group April 2008 There must be collaborative development between the SNOMED CT Concept Model and an information model in order for effective implementation of SNOMED CT

9 How many bridges? How many bridge building techniques?

10 IHTSDO … open for business on information models and terminology binding  Information modelling and terminology binding is on the IHTSDO work plan for 2014  Additional strength in the team  Linda Bird joining as Implementation Specialist  + several SIAs with relevant skills and experience  but …  Which group(s) to work with and how

11 Puzzling questions for IHTSDO!  Who to work with?  How many groups to work with?  Which model/pattern representations? (prefer ONE)  Which representation of terminology components?  Precoordination – one code  Postcoordinated expressions  Postcoordination in models  How much of the model interests IHTSDO?  Terminology of course … but also structural elements impact semantics … where are the boundaries  Very little interest in demographics

12 There are big mountains to climb …

13 What our customers need  What do IHTSDO Members need?  Meeting immediate needs  Simplification without compromise  What are the clinical use cases?  Many and varied but they follow several common patterns  What are the vendor drivers?  Need scalable implementation approach  Growth of market plus … retention or growth of market share  Improvement of SNOMED CT while avoiding disruptive change  Stepwise implementation from simplistic code use to rich semantics  An accessible base-camp and a route towards a summit
