International Classification of Diseases (ICD)

ICD-10 was endorsed by the Forty-third World Health Assembly in May 1990 and came into use in WHO Member States as from 1994. The classification is the latest in a series which has its origins in the 1850s. The first edition, known as the International List of Causes of Death, was adopted by the International Statistical Institute in 1893. WHO took over the responsibility for the ICD at its creation in 1948 when the Sixth Revision, which included causes of morbidity for the first time, was published.

The ICD has become the international standard diagnostic classification for all general epidemiological and many health management purposes. These include the analysis of the general health situation of population groups and monitoring of the incidence and prevalence of diseases and other health problems in relation to other variables such as the characteristics and circumstances of the individuals affected.

It is used to classify diseases and other health problems recorded on many types of health and vital records including death certificates and hospital records. In addition to enabling the storage and retrieval of diagnostic information for clinical and epidemiological purposes, these records also provide the basis for the compilation of national mortality and morbidity statistics by WHO Member States.

Provincial Ministry of Health Report listing Autism as a disease

The Institute for Clinical Evaluation Services was solicited by the Ministry of Health and Long Term Care to prepare a report regarding Autism prevalence rates in Ontario using the O.H.I.P. data base. ICES informed FEAT that no cover page to the report ever existed. When FEAT asked if anyone from the Ministry or any Ministry followed up on the report to rebut any of it’s findings, specifically medical wording in the document, FEAT was told that there had never been any further consultation or inquiry from the Ministry regarding this document. The Ministry accepted the classification of autism as a “disease” as outlined in the report. While ICES warns against accuracy of the prevalence rates in the report due to different billing structures by physicians the reason FEAT has included it under diagnosis to show that the Government of Ontario accepted in whole this telling report from this highly reputable source.

Diagnosis

Autism is diagnosed in a variety of ways, using a number of different measures.  (In North America, the DSMIV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition).   This is put out by the American Psychiatric Association.  In Europe and other parts of the world, the ICD-10 (International Classification of Deaseses) is commonly used. 

One measure that has particular appeal is the CHAT.

The CHAT is a HIGHLY accurate and elegant autism screening tool for early autismdiagnosis. Research supporting the CHAT is published in the British Journal of Psychiatry (1996, 168, pp. 158-163; 1992, 161, pp. 839-843).   These studies have found that the CHAT is 85% accurate in diagnosing children with autism and 100% accurate in diagnosing a developmental delay in general. 

This important tool can be given to primary care physicians and pediatricians who see young children first and are the entry point into the health care system for infants and toddlers. The earlier they can confirm a diagnosis of autism, the more effectivebehavioural treatment is likely to be.  Physicians can use the CHAT on children 18 months of age or older.
