Health Information Systems: Analog to Digital How do we optimize our health services
ICD-11 Revision Goals Evolve a multi-purpose and coherent classification 1. – – Mortality, morbidity, primary care, clinical care, research, public health… Consistency & interoperability across different uses 2. Serve as an international and multilingual reference standard for scientific comparability and communication purposes 3. Ensure that ICD-11 will function in an electronic health records environment. • Link ICD logically to underpinning terminologies and ontologies (e. g. SNOMED, GO, …) • ICD Categories “defined” by "logical operational rules" on their associations and details
Construction of ICD-10: Revision Process in the 20 th Century • 8 Annual Revision Conferences (1982 - 89) • 17 – 58 Countries participated – 1 - 5 person delegations – mainly Health Statisticians • Manual curation – List exchange – Index was done later • " Decibel" Method of discussion • Output: Paper Copy • Work in English only • Limited testing in the field
Construction of ICD-11: Revision Process in the 21 st Century • Internet-based permanent platform – All year round – Open to all people in a structured way – Content experts focus • Digital curation – Wiki enabled collaboration – Ontology based • Enhanced discussion & peer review – TAGs serve as the Editorial Group • Electronic copy print version • Work in multiple languages • Planned field tests – Based on Use Cases
Definition of Disease a set of dysfunction(s) in any of the body systems including: • with a known pattern of signs, symptoms & findings » symptomatology - manifestations • probably with an underlying explanatory mechanism » etiology • a distinct pattern of development over time » course and outcome • a known pattern of response to interventions » treatment response • with linkage to underlying genetic factors » genotypes, phenotypes and endophenotypes • with linkage to interacting environmental factors
What is Ontology? • Ontology (philosophy) – the Organization of Reality • !!! Ontology (computer science) – the explicit – operational description of the conceptualization of a domain: • Concepts: entity and quality (properties and attributes) • An ontology defines: – a common vocabulary a shared understanding/exchange: • among people • among software agents • between people and software – to reuse data - information – to introduce standards to allow interoperability

Why work together? – WHO & IHTSDO – – – Coverage & Adequacy Quality – Reliability - Utility Multi. Lingual Applicability Interoperability Sustainability – Member States: Enable health care delivery and compile health information SNOMED & WHO Classifications are synergistic and not antagonistic
ICD & WHO FIC • International Public Good – Openly Accessible – Free for WHO Member States • Available in multiple formats: – Printed Book editions – Internet-edition – Various computerized tools
ICD & WHO FIC – Simultaneous development in Multiple Languages – ﺍﻟﺘﺼﻨﻴﻒ ﺍﻟﺪﻭﻟﻲ ﻟﻸﻤﺮﺍﺽ – 國際疾病與相關健康問題統計分類 – International Classification of Diseases – Classification internationale des maladies – Международная классификация болезней – Clasificación internacional de enfermedades
ICD & WHOFIC • Multiple Settings: – Primary Care – Clinical Services – Research • Specialty Adaptations: – Children and Youth – – – Oncology Mental Health Neurology Musculoskeletal Dermatology Dentistry e. g. ICD-10 Diagnostic Guidelines for Mental Health in Primary Care
Desiderata for a global terminology (1) 1. Comprehensiveness: – Coverage for all aspects of health care 2. Adequacy: – Is it fit or purpose – multiple purposes? – Does it have a good information model and ontological basis? 3. Multilingual applicability – language independent formal concept representation – Representation in multiple languages – more than translation 4. Utility: – Is it beneficial for: • Care providers • Consumers • Policy/Decision Makers 5. Reliability: : decision making, outcome evaluation : participation – ownership – evaluation – risk reduction : informed decision making on costs, benefits, efficiency – does it give the same results in different users
Desiderata for a global terminology (2) 6. Validity: – Does it indicate the right things – and does the indication make sense 7. Comparability • Does the data in different context have same properties to be compared? 8. Interoperability – Technical: Can information systems exchange information and use it? – Semantic: Can information systems interpret the data with the same meaning? 9. Quality Assurance – Product: Annotation and Content – Process: Use and Usability 10. Sustainability – Secured maintenance: commitment to stability with earlier versions – Openness to address emerging technical issues
