1 WHO Agenda: Classifications – Terminologies - Standards
Digital Health and Electronic Medical Records: Aligning the EU and UK Agendas 15th July 2010, RCP London, UK WHO Agenda: Classifications – Terminologies - Standards Nenad Kostanjsek World Health Organization

2 Placing WHO Classifications in HIS & IT of the 21st Century
KRs Mappings Terminologies e-Health Record Systems ICD ICPS ICF ICTM ICHI Population Health Births Deaths Diseases Disability Risk factors Clinical Decision Support Integration of care Outcome Administration Scheduling Resources Billing Reporting Cost Needs Classifications 2

3 The desiderata for a WHO FIC in 21st Century
Evolve a multi-purpose and coherent WHO classification which are consistent yet adaptable and interoperable across different uses (public health, service management, research) the spectrum of health care (Primary, Secondary, Tertiary) in developing and developed countries compatible with other WHO classifications Serve as an international and multilingual reference standard for scientific comparability and communication purposes Ensure that WHO classification will function in an electronic health records environment. Link WHO FIC logically to underpinning terminologies and ontologies (e.g. SNOMED, GO, …) WHO FIC categories “defined” by "logical operational rules" on their associations and details

4 Key workstreams & elements for developing WHO FIC
Use cases Content model (parameter & value set) Population & peer review of content model Web based collaborative authoring tool (iCAT) Ontology development

5 ICD 11 is no longer just lists…it is based on a content model

6 THE CONTENT MODEL Any Category in ICD is represented by:
ICD Concept Title: Name of disease, disorder, or syndrome Classification Properties: Parents, Type, Use Textual Definition(s): Fully Specified Name Terms: synonyms, Index, inclusion, exclusion Clinical Description: Body System(s), Body Part(s), [Anatomical Site(s), Histopathology Manifestation Properties: Signs & Symptoms, Findings Causal Properties: etiology type, agents, mechanisms, genomic characteristics; risk factors Temporal Properties: age of occurrence & occurrence Frequency, development course Severity Properties Functioning Properties Specific Condition Properties Treatment Properties Diagnostic Criteria External Causes Maintenance attributes Unique identifier Mapping relationships Linkages to other systems like SNOMED etc. Other rules 6 6

7 ICD 11 Foundation Component and Linearizations
ICD-11 content model parameters - Definitions, synonyms - Clinical descriptions - Manifestation properties - Causal properties - Functional properties Specialty Adaptation Primary Care Linearizations Morbidity Mortality Value Set SNOMED-CT, International Classification of Functioning, Disability and Health (ICF), International Classification of External Causes of Injury (ICECI)…

8 Web based collaborative authoring tool (iCAT)
display & browse taxonomy with its content model rubrics allow user to comment on the content allow users editing the content and facilitate the use of value sets derived from other classifications and terminologies allow user restructuring the classification Incorporates multiple level of user access supports multilingual representation ontology tooling interface with description logic technology

9 Making WHO FIC ontology based Example: ICPS ontology development
has cause Hazard Incident type Incident has type has circumstances Contextual Factors has impact has consequence Harm Action is a is a Patient outcome Managing action Preven. action Org. outcome Injury Adverse Reaction Disease Disability is a

10 WHO classification development in the 20th Century Construction of ICD-10 & ICF:
ICD: 8 Annual Revision Conferences ( ) ICF: 7 int. & 38 nat. Revision Conferences ( ) ICD: 17 – 58 Countries participated 1- 5 person delegations mainly Health Statisticians ICF: 61 Countries participated Multi-disciplinary Manual curation List exchange Index was done later "Decibel" ? Method of discussion ICF: Concept driven Output: Paper Copy Work in English only ICD: Limited testing in the field ICF: drafts translated into / tested in 27 languages post-coordinated development of linkages to related classification, terminologies and assessment instruments

11 WHO classification development in the 21th Century
Internet-based permanent platform All year round Open to all people in a structured way Linkages to related classification, terminologies and assessment instruments Content experts & users are empowered Digital curation Wiki enabled collaboration Ontology Enhanced discussion & peer review Electronic copy  print version Work in multiple languages field tests based on Use Cases
