ICF history - the ICIDH and its redevelopment
The predecessor of the ICF was the ICIDH (International Classification of Impairments, Disabilities and Handicaps) which was originally proposed to describe the effects of chronic conditions such as arthritis and the long-term effects of rehabilitation. In 1980 the ICIDH was published by the WHO, as a 'manual of classification relating to the consequences of disease' (and injuries and other 'disorders') and as a 'conceptual framework for information'. Since its release, a number of review articles described the potential applications and uses of the ICIDH, including:
- conceptual development in interdisciplinary fields related to disability;
- medical and rehabilitation monitoring systems;
- survey research;
- data base development;
- clinical diagnosis and rehabilitation assessment; and
- programme evaluation.
By 1994 the ICIDH had been translated into 13 languages. However, some criticism was levelled at the ICIDH, in particular from people with disabilities and many professionals who were critical of the inadequate recognition given to the role of the environment in the creation of disability. Seven years of revision and testing ensued.
A summary of the ICF revision process, focussing on the contribution made by the Australian Collaborating Centre, is outlined in the following pages.
AIHW hosts a workshop on 'measurement disability' and is subsequently invited to extend our Terms of Reference as a WHO Collaborating Centre to include ICIDH revision. In November, AIHW attends its first ICIDH revision meeting and is asked to taken an interest in Participation and Environment.
AIHW reports to WHO on work to establish the Disability Data Reference and Advisory Group (DDRAG). A paper is presented on applications in Australia.
AIHW comments on alpha draft and WHO '15 issues', advised by DDRAG.
1997 to 1998
Beta 1 (ICIDH-2) draft is published
AIHW attends meetings and
On the basis of extensive testing and discussion, AIHW reports to WHO several times during the year.
AIHW September 1998 report on Beta 1 testing:
Key findings of March 1998 - still applicable to ICIDH revision
The draft ICIDH-2 is a useful, integrating conceptual framework and represents an improvement on ICIDH-1
The draft ICIDH-2 could provide a framework for the relatable data collections in Australia.
'Personal factors', while important, should not be included as contextual factors.
The word 'disability' is entrenched in Australian terminology and legislation and is unlikely to be replaced by 'disablement' except as a more theoretical word to denote the process of becoming disabled.
Key findings of March which have since developed further on the basis of Beta testing
Editorial effort is needed to:
clarify the purpose of the classification, and its location in relation to health and other WHO classifications, and to the UN Standard Rules on the Equalisation of Opportunity;
remove perceived overlap between P and A;
improve the structure of P domains.
Developmental work is needed to:
While further work has now been done on the development of Participation qualifiers, more work is needed to ensure that
the importance of the role of the individual in the classification process is recognised (whatever the outcome of Option 15a testing);
in relation to the role of 'choice' in Participation, that there is clarification on how to approach the classification when choice itself is limited by social attitudes; and
the Participation qualifiers are made more useable in practice.
A final AIHW report to WHO in December 1998 confirms these main issues.
AIHW participants vigorously in the lead up to finalising a 'Beta 2 draft'.
Recommendations to WHO and revision meeting:
Annual ACC report to WHO 1999 (141K DOC)
The final position of the Australian Collaborating Centre on the Beta 2 draft will depend on our satisfaction with our three main areas of concern: the Introduction, the Participation/Activity overlap, and the qualifiers.
Activity qualifiers should preserve the concepts of 'difficulty' and 'assistance'.
We recommend adoption of the Australian proposals for Participation qualifiers, namely
Extent of participation (in relation to the person's goals) - essentially Option 15a; and
Extent of participation adoption (external rating or comparisons to statistical averages) - essentially the 1997 Beta draft qualifier.
We support the Environment facilitator/barrier qualifier proposed by the E Task Force.
None of the tests currently proposed for Beta 2 testing should be made 'compulsory'.
The involvement of people with disabilities in Beta 2 testing is essential.
The present 'clinical emphasis of the proposed tests is inadequate and unsatisfactory.
Our suggestions for other tests (above) should be included in the package of possible tests.
Various proposals for resolving the perceived overlap of Activity and Participation are put forward by various Centres.
AIHW conducts conference on health and related classifications and a paper on the ICIDH is presented.
A paper is presented at the North American Collaborating Centre Meeting on potential users of ICIDH in Australia.
Beta 2 (ICIDH-2) draft published in mid 1999
In terms of its contents, the AIHW probably had most success with the main schematic diagram and the E qualifiers which owe their origin to work we did on the P qualifiers. A number of detailed comments and contributions had an effect, combined with other similar comments.
AIHW makes plans for Beta 2 testing using WHO protocols.
Beta 2 testing starts.
AIHW reports to WHO interim meeting in June on ICIDH Beta testing conducted so far and suggested changes to the classification. (This is essentially the final report, with a subsequent final report on Study 3 testing submitted separately).
In May 2000 WHO circulates a paper on 'ICIDH-2 development options', outlining new issues to be addressed in final draft e.g. health and health status measurements, leading to new concepts and qualifiers. Debate among Collaborating Centres ensues.
In October WHO releases a new 'prefinal' draft
After Australian intervention at a meeting on health status measurement in Ottawa in October, Collaborating Centres and WHO begin to work on a compromise to preserve the best of the Beta 2 and the WHO proposal.
Final revision meeting held in November in Madrid. Several centres (Netherlands, US, Canada, UK and Australia) propose a 'compromise' which is further developed in out-of-session meetings.
WHO Executive Board meeting results in disentangling the recommendation to endorse the ICIDH from possible recommendations about measurement.
The World Health Assembly officially endorses the International Classification of Functioning, Disability and Health and the acronym ICF in May 2001:
The Fifty-fourth World Health Assembly,
- ENDORSES the second edition of the 'International Classification of Functioning, Disability and Health' (ICF)
- URGES Member States to utilize the ICF in their research, surveillance and reporting as appropriate, taking into account specific situations in Member States, and, in particular, in view of potential future revisions.
- REQUESTS the Director General to assist Member States, on request, to make use of ICF.
A UN seminar on measurement of disability is held in New York in June. An Australian paper is given on ICF implementation issues.
The first meeting of the WHO Family of International Classifications is hosted by the North American Collaborating Centre in Bethesda.
Australian papers presented are:
- Bethesda.09.doc: Annual report of the Australian Collaborating Centre (Richard Madden, AIHW)
- Bethesda.55.doc: Implications for the ICD of the ICF (Family Development Committee)
- Bethesda.58.doc: Possible application of International Classification of Functioning, Disability and Health in Rehabilitation (Catherine Sykes, Ros Madden and Jenny Hargraves, AIHW)
- Bethesda.60.doc: ICF Australian User Guide - An outline for discussion (Ros Madden and Louise York, AIHW)
- Bethesda.61.doc: National information agreements, data dictionaries and quality of health and welfare data (Ching Choi, AIHW)
Note: Papers from the Bethesda meeting are available from the World Health Organization website.
The Australian launch of the ICF was held in Canberra in December 2001.
