Thank you very much, Madam Chair. My apologies for being a little late in arriving this morning. I was battling the traffic on the Queensway.
I'm very pleased to be here this morning from the Public Health Agency of Canada to provide you and the subcommittee members with an overview of the agency's work on surveillance of autism spectrum disorders.
I will start by briefly giving you an overview of health surveillance generally. Then I will focus on the development of the autism surveillance program.
As many of you will know, health surveillance is a core public health function, and it is a critical part of the work we do at the Public Health Agency of Canada. What is surveillance? Surveillance is the ongoing, systematic process of data collection; expert analysis and interpretation; and, most importantly, communication of the resulting information for public health action.
The information we use may include rates of a health condition; emerging trends over time; variations in the occurrence of a health condition according to specific populations or geography--where those populations live; information about risk and protective factors, and so on. There are many ways we do surveillance and many types of data that we collect.
With our surveillance information, governments, health care providers, public health practitioners, researchers, and Canadians can take action to prevent disease and promote health. The responses may be in the form of policy and program development, changes in clinical or public health practices, provision of advice and education to the public, or research. As you can see, there's a broad range of uses for the surveillance information we provide, and we are very careful to collect that information to meet the needs.
I will now focus on the development of a national autism spectrum disorder surveillance program. Autism spectrum disorder, as you know, is a group of neurodevelopmental conditions that typically occur before three years of age. These conditions are characterized by impaired verbal and non-verbal communication, impaired social interaction, and repetitive behaviours. Rates of autism spectrum disorders in Canada have been estimated at 6.5 per 1,000, based on studies by researchers such as Fombonne, and studies from the Senate Standing Committee on Social Affairs, Science and Technology, in their 2007 report.
The lack of complete and reliable epidemiologic data on autism spectrum disorders in Canada resulted in the identification of the need for a national surveillance system that would be equipped to fill information gaps and provide reliable information in three areas. First is the prevalence of autism spectrum disorders: how common are these disorders, and how do they differ in prevalence across the country? Second is to describe the population of children with autism spectrum disorders. Third is to understand changes in prevalence of these disorders over time.
We have a strong foundation in the agency and with our partners, on which we are building. The national epidemiologic database for the study of autism in Canada was established in 2001 and is coordinated by Queen's University. Researchers, clinicians, and government agencies in six regions of Canada are collaborating to better understand and estimate the prevalence of autism spectrum disorders.
A prerequisite for successful surveillance is standardization of case definitions and data collection. We want all of the people participating in surveillance to be collecting the same thing, according to the same definition, in the same way, so those data are reliable. We are working with Queen's University to develop and test surveillance methodologies for ASD based on their experience with the national epidemiologic database.
We have consulted with key stakeholders, including parents, caregivers, individuals with autism spectrum disorders, health and service providers, researchers and clinicians, and other persons affected by these conditions.
In brief, the priorities for a surveillance system of developmental disorders should include a valid case definition based upon scientific evidence, and a comprehensive selection of indicators that accurately describe the spectrum of disorders and enable an accurate estimation of the burden of illness in Canada.
In November, we attended the Geneva Centre for Autism's international symposium in Toronto, Autism 2010, and had an opportunity to hear first hand the needs of patients and families and from organizations working to provide services to children with developmental disorders such as autism. Through meeting with international counterparts and national experts, we learned first hand of the need for a coordinated national approach towards assessing the burden of disease related to the spectrum of autistic disorders in Canada.
At this point we're in the process of establishing our scientific advisory committee for the autism surveillance program. We will work with this committee to identify and confirm the measures or indicators we should be monitoring. This will be building on work we're already doing with Queen's University.
This process will define the specific data needs and our approach to data collection. We will benefit from the considerable depth of expertise on autism spectrum disorders that exists in Canada in research, clinical care, social services, and through organizations representing the needs of children and families.
This includes the work of the Canadian Autism Spectrum Disorders Alliance and Autism Speaks Canada. As you know, members of these organizations are committed to the establishment of a national autism surveillance program. We are working with these organizations to ensure the information from the surveillance program is communicated to stakeholders, that we receive their feedback, and that opportunities for ongoing dialogue are established.
To accelerate our efforts in establishing our surveillance program, we have dedicated a senior epidemiologist to manage the development of the program. The most important next step is the establishment of our scientific advisory or steering committee. This committee will begin its work early next year to identify and confirm the measures and indicators that will form the basis of our program. It will help us determine the best ways to collect these data. Our plan is to build upon the considerable depth of expertise that already exists in order to build a surveillance program that will accurately assess the burden of illness in Canada.
Thank you, Madam Chair. I would be happy to answer any questions from the committee.
