Mediation between People, Languages, Cultures, and Machines Pieter E Zanstra Radboud University Nijmegen Medical Center Co-ordinator EU SemanticHEALTH Specific Support Action: Semantic Interoperability Deployment and Research Roadmap eHealth2006: High Level Conference and Exhibition, Malaga, May 12, 2006
2 Reviewed. Primip FT No ANC probs F/D at 08:45 Needed synto for contractions about 7cm Decent progress since. Epidural in-situ No urges to push really according to patient Contractions 4:10 but poor duration & strength (on 60 u/s /synto) PA: Ceph 0/5 VE: Head at +1 Caput +1 No ??? OA position Cx F/DNO DESCENT Tried pushing – poor maternal effort despite instruction Although epidural working well, doesn’t stop longstanding spasmodic hip pain. Very problematic FHR CTG No descent with attempts at pushing – poor effort. Plan…a) Push synto b) Need really try to push & work on technique c) reassess at interval 15 mins & D/W consultant Would not be happy to have to exert traction with Forceps when no effort & no descent Where are we coming from..
3 Competing demands on recording Record Categorise ICD, ICPM DRG Documentation Referral letters ? Grouper Classifier Reimburse Manage
4 What kind of business logic do we need? Record ICD, ICPM DRG Documentation Grouper Classifier Reference Terminology Service
5 CEN/ISSS eHealth FG Recommendation 13 (2005) The Member States, with the Commission, should: –ensure the Europe wide referencing and easy access to the content of existing health coding systems based on registration of such systems by the Eurorec Institute; –support the international convergence towards a common framework for formal representation, and eventually the development and maintenance of a multilingual clinical reference terminology. This effort should build on existing efforts in formal representation as GALEN, FMA and SNOMED, and be carried out in liaison with the WHO Family of International Classifications –make the targeted reference clinical terminology publicly available free of charge; –support a common approach to link national classifications of procedures, to support cross-border reimbursement of health care.
6 Clinical terminology A clinical terminology is the collection of standard terms with their synonyms, which in the context of patient care support the recording of complaints, signs, symptoms, circumstances, process of illness, interventions, results, diagnoses, as well as the decision making of the care providers
7 What binds Records, Interface, Reporting, Knowledge…? Interface Terminology Reporting Terminology (ICD) Reference Terminology Health Record Discharge Referral..
8 Record architecture terminology (mediation) Name, Context and Content physical examination breast palpation lump present CONTENT NAME CONTEXT
9 Sound semantics underpinning continuity in care
10 What is a term referring to? Blood pressure –Evaluation result (high, low) –Measurement (diastolic, systolic) Archetype/Template? –Guideline (how to measure?) Rheumatoid arthritis –Evaluation result –Measurement (criteria)
11 Reinhold A. Mainz, BMGS, Germany, Project Group Telematics – Health Card 14./15. February, Bruxelles, EC / WHO Workshop on Semantic Interoperability Semantic interoperability (example of drugs with different trade marks) The example: A patient coming from Switzerland to a German pharmacy is looking for a drug well known in Swiss: „DROSANA Resiston Trpf.“ The name of this drug is not known in German pharmacies! The pharmacist will not find this drug in his drug data bases, is not able to identify the ingredients of the drug, can not look for an equivalent drug available in Germany.
12 35 Multiprofessional Records and terminology Differences in vocabulary Differences in the meaning of the vocabulary Differences in aspects/abstractions –Nurse: ‘constipation’ is an elimination problem –Doctor: ‘constipation’ is a bowel function disorder Difference in operational significance –Reflecting differences in professional tasks
National Institute for Public Health and the Environment 13 Classification & Model of Use
National Institute for Public Health and the Environment 14 Classification & Model of Use
16 And there is more to come…… Official Inventory on IT systems –52 ‘exotic’ patient record systems –1 ‘summary-system’ used by 250 physicians of which 70 daily containing patients Inventory by students –Estimated 200 ‘exotic’ systems –At least 200 shortlists for diagnosis, treatment –Only some terminologies properly documented/maintained
18 The next Challenge: Adequate data capture ! Structured Data Entry File Edit Help What you hit Your Role Activity Location Cycling Accident

20 Some Myths Stage of development Open Source Evidence Based Medicine Open source will most definitely not be free of cost; A complex terminology is required, and we should not expect this to appear without significant investment The critical mass of skilled & dedicated contributors to a large Health terminology is too small for a sustainable system Only about 5-8% of present medical knowledge is based on sound evidence. RCT’s are very costly and time-consuming. We can not longer ignore the need for routinely collected observational data of high quality. Problem of finding ‘outliers’ in the literature
21 A bit of Archeology (1) 2 nd EU/CEN Workshop (1997) –Central resources - public or private - are urgently needed for European Industry to address a single market Central reference resource of concepts Multilingual lexicons Language independent development tools –A strategy to maximise European influence on international developments is needed New developments in HL7, CorbaMed, DICOM, UMLS Establishing evolutionary pathways from existing systems to future systems –Communication architectures should address mediation & conversion
22 A bit of Archeology (2) SESAME Committee (1990) –Medical Semantics Advisory Task (Mesat) –Establish national standardisation organisations for semantical aspects in medicine –European medical termbank (Eumet) –European Model of Health Care (Euromodel) –European Classification of Medical Procedures (Euclamep) –Harmonization of validation and coding rules for ICD
23 Still many open questions What level of detail is required Revolutionairy/evolutionairy implementation How do we cope technically How do we cope in the business process How do users cope cognitively How do we cope with version control in the new highly interdependent architectures
24 Observations Development still driven by ‘perceived need’ No yet hard evidence to prove added value For the next five year seen by industry as exhaustive list of fixed terms Growing evidence to reconsider the ontologies behind systems –Both SNomed CT and GALEN stem from early 90s Systems not plug and play –Significant cost of translation –Multitude of base cost goes into localisation
25 Clinical Terminology Summary Evolving use case –Epidemiology –Organising care –Documenting Care –Access to knowledge Unsolved Problems –Quality Assurance –Efficient data capture –Interrater variability –Cost Model Technological Barriers –Enumeration doesn’t scale –Computers can’t read –Humans can’t organise –Tower of Babel Evolving Technology –Enumeration – ICD –Interlingua – UMLS –Formal Ontology – SNOMED CT
26 Recommendation: Establish the process Focus on real immediate needs, and realistic time scales Be prepared to throw away what you loved and cherised! Be aware and secure solutions for different cultures/ languages Do not just select a single product, but join forces to redesign with best of breed Involve and explain to those who have the burden of recording (registration dividend) Without a well managed network of compentent expertise centres, the process is likely to fail
