Question 7: What Other Infrastructure and Surveillance Needs Must Be Met?
- What infrastructure systems need to be supported, strengthened, or built to support this plan?
- How can we ensure that resources and data are shared to support the scientific research process?
- How can we ensure that findings are communicated to the public in a responsible and timely manner?
- How can we improve autism surveillance efforts?
What do we know and what do we need?
Current infrastructure may be insufficient to adequately support the research programs outlined in this plan. Additional investment in infrastructure is necessary to collect and share data among researchers, to encourage and enable individuals with ASD and their families to participate in research, and to improve the speed with which findings are disseminated and the extent to which findings are translated into practice and policy.
In 2006, the National Institutes of Health (NIH) launched the National Database for Autism Research (NDAR) to improve sample sizes and enable researchers to share data for increased analyses. The NIH-supported national Autism Centers of Excellence (ACE), as well as the grants funded under the "Research to Address the Heterogeneity in Autism Spectrum Disorders" Request for Applications as part of the American Recovery and Reinvestment Act (ARRA), receive funding contingent upon acceptable plans and means for data sharing. Incentives are needed, however, to encourage data submission by other researchers. It will also be necessary to link other significant ASD databases with NDAR. In addition, databases that collect information and coordinate recruitment of people with ASD and their families to participate in research studies need to be enhanced and expanded. Programs to support contribution of data for recruitment, healthcare, education, social services and administrative databases, like the Interactive Autism Network (IAN), should be encouraged. Collecting information about people with ASD will facilitate the study of whether early diagnosis, entry to services and type of intervention affects the course of ASD over time. Multiple data sources from existing research or service systems (e.g., education, Medicaid, etc.) currently operate in isolation. Compiling and sharing data from existing data sources need to address data standardization as well as important privacy and ethical issues. Methods for merging such databases and linking investigator-recruited samples to these merged databases have been used in other populations and in specific locales with success and need to be further developed.
Many in the field have highlighted the need to establish nationally coordinated strategies for the collection and preservation of post-mortem tissue from both people with and without ASD. The existing brain and tissue bank resources must be expanded to meet the high and continuously increasing demand for post-mortem tissue by scientific investigators. More well-preserved brains are needed from people at various stages of development and particularly from those with few co-occurring disorders. Additional matched controls are needed, as well, to supplement the limited supply in existing repositories.
In addition, it will be necessary to develop methods, standards and protocols for collecting and storing other biological specimens such as blood and urine which might be used to study biological differences or signatures, and skin fibroblasts for creation of pluripotent stem cells.
Autism surveillance provides important estimates on the numbers of children affected with ASD and helps describe the characteristics of the people with autism spectrum disorders in the general population. Surveillance must be sustained over a period of many years in order to track trends in prevalence estimates over time, and is an essential building block for population-based research - providing clues about potential risk factors that warrant further study. Surveillance provides important data regarding early identification of children with autism, and informs education and health systems regarding areas in which programs can be modified in order to improve early identification and intervention. Surveillance data also provide critically important information for communities to use when planning for services.
In 2007, CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network published the first and most comprehensive summary of autism prevalence estimates in the United States (CDC, 2007). These data showed that between 1 in 100 to 1 in 300 (with an average of 1 in 150 children) were identified with ASD. In October 2009, investigators from HRSA and CDC reported that ASD occurs in an estimated 1.1% of children 3 to 17 years, based on parent-report during the National Survey of Children's Health (NSCH), sponsored by HRSA (Kogan et al., 2009). Updated estimates from CDC's ADDM Network, published in December 2009, confirmed that approximately 1% of children were identified with an ASD (between 1 in 80 to 1 in 240 children with an average of 1 in 110) (CDC, 2009). There was an increase of 57% in identified ASD prevalence from 2002 to 2006 in multiple areas of the US. While these data provide important information for service planning, and begin to help us understand that the increases are not fully accounted for by improved identification, many questions related to the multiple causes of ASD increases remain.
There are a number of areas in which prevalence studies could be improved, including the continued estimation and evaluation of prevalence in the same population over time; assessment of ASD prevalence in the context of other neurodevelopmental disorders; further analyses of existing datasets to examine the multiple identification and potential risk factors as they vary by prevalence; collection of data beyond core ASD symptoms, including genetic data and co-occurring medical, dental, and behavioral conditions; and expansion of studies across ages.
Supporting international autism surveillance activities, prevalence estimates, and epidemiologic research will also be important, in order to compare prevalence estimates and epidemiologic characteristics across countries.
Communication and Dissemination
Research data regarding autism is now being published at a rapid rate. It is critical that new findings are communicated promptly and appropriately to the public so that research findings can be better translated into practice as appropriate. Effective translation is important so that new findings can be utilized to improve risk assessment and implementation of individualized interventions to reduce the disabling symptoms and promote a positive developmental trajectory as early as possible. Additional attention needs to be paid to improving the communication channels between scientists, practitioners, people with ASD and their families.
There is also need to build a system for rapid replication studies concerning key findings. In addition, there is still not agreement about meaningful subtypes or about how to individualize treatment. As more professionals become involved in autism research, there is a need for organized input from established scientists to provide guidance and expertise.
In addition, it will be necessary to identify and address the wide range of ethical and clinical issues related to the diagnosis, assessment, and communication of genetic, environmental, and clinical risk for autism.
Research Workforce Development
In order to accomplish the necessary research in the field of autism, it will also be important to develop an adequate scientific workforce. While much autism research is already underway, there are several areas of research that are new and growing, including interdisciplinary research, where additional researchers will be needed in the coming years. In fiscal year 2009, there were 92 trainees (graduate students and postdoctoral fellows) supported by specific NIH training and fellowship grants to study autism. These are in addition to the trainees supported on more than 300 NIH research grants focused on autism. The continued expansion and development of this research workforce will be essential to fulfilling the goals laid out in the IACC Strategic Plan.
Short-Term and Long-Term Objectives
