World Health Organization Classification Assessment Surveys & Terminology Group

1. World Health OrganizationClassification Assessment Surveys & Terminology Group ICF as the New Member in the WHO Family of International Classifications www.who.int/classification/icf

2. Basic Messages • ICF has been systematically revised in the last decade • large international and multidisciplinary participation • extensive field testing • guided by scientific principles • taxonomic guidelines: logic and terminology • practical utility: feasibility, ease of use, ethical guidelines • reliability, validity and comparability • When the rubber hits the road... • ICF can serve as a useful tool for Health Information Systems • evaluation: needs, outcomes, costs, quality, satisfaction • service provision, social policy • Application guidelines, training, tools are needed

3. World Health Assembly • Endorse and publish ICF • use the ICF in Member States in: • research • surveillance • reporting • Joint use with ICD • Operational subsets: • surveys • clinical encounters • Periodic revision

5. ICF Publications • 1. Main volume with glossary • - Full version 9999 cat. • - Short version 99 cat. • 2. Clinical Descriptions • & Assessment Guidelines • 3. Assessment Criteria • for Research • 4. Other versions • - Specialty adaptations • Children and Youth • 5. Dedicated • Assessment Tools

6. Aims • to provide a scientific basis for consequences of health conditions • to establish acommon language to improve communications • to permit comparison of dataacross: • countries • health care disciplines • services • time • to provide asystematic coding scheme for health information systems

7. Foundations of ICF Human Functioning - not merely disability Universal Model - not a minority model Integrative Model - not merely medical or social Interactive Model - not linear progressive Parity - not etiological causality Context - inclusive - notperson alone Cultural applicability - not western concepts Operational - not theory driven alone Life span coverage - not adult driven

8. Human Functioning not disability alone • Body functionsvsimpairments • Body Structures • Activitiesvsactivity limitation 1980 disability • Participationvshandicap

9. Participation or Handicap? • neutral language • “politically correct” • correct use • intervention • opportunity • positive aspects

10. Universal Model vs. Minority Model Everyone may have disability Continuum Multi-dimensional Certain impairment groups Categorical Uni-dimensional

11. Medical versus Social Model • PERSONAL problem vs SOCIAL problem • medical care vs social integration • individual treatment vs social action • professional help vsindividual & collective responsibility • personal vs environmental adjustment manipulation • behaviour vsattitude • care vs human rights • health care policy vs politics • individual adaptation vs social change

12. Impairments Disabilities Handicaps Sequence of Concepts ICIDH 1980 Disease or disorder

13. Body function&structure(Impairment) Activities (Limitation) Participation (Restriction) Environmental Factors Personal Factors Interaction of Concepts ICF 2001 Health Condition (disorder/disease)

14. Equity / Parity • Loss of limb landmines = diabetes = thalidomide • Missed days at usual activities flu =depression = back pain = angina • Stigma leprosy = schizophrenia = epilepsy =HIV

15. Contextual Factors • Environment • Products • Close milieu • Institutions • Social Norms • Culture • Built-environment • Political factors • Nature Person • gender • age • other health conditions • coping style • social background • education • profession • past experience • character style

16. Cultural Applicability • Conceptual and funtional equivalence of Classification • Translatability • Usability • International Comparisons

17. Comparability: equivalence across cultures • Conceptual equivalence: • similar understanding /meaning of concepts • Functional equivalence: • similar domains • Metric equivalence: • similar measurement characteristics

18. ICF Field Testing • 7 years 1994-2001 • 61 countries • ICF drafts translated into / tested in 27 languages • 38 National Consensus Conferences • 7 International Consensus Conf. • 2000 Live Case evaluations • 3500 Case Summary evaluations

25. ICF in health & disability statistics • Common Domains • Mobility - Cognition - Mood • Self Care - Usual Activities ... • link data from both health and disability • Multiple Components • overcomes the “impairment” focus • Environmental Factors • Comparability

26. ICF in clinical practice & management • Needs assessment • Outcome assessment • Utilization patterns • Comparison of different interventions • Consumer satisfaction • Service performance • outcomes • cost-effectiveness • Electronic records • Clinical terminology

27. ICF in policy making • assessment of population health • impact of disability • economic • social • evidence-base for policy makers on different policy interventions • responsiveness of services • efficiency • performance assessment

28. ICF research applications • joint assessment of disease and functioning • description of association • intervention response & synchrony of change • explanatory power on: • utilization • needs • costs • outcomes • Cost-effectiveness of interventions • Unified approaches
