Many children with developmental problems and their families are not receiving all of the services they need because their primary care provider is not making sufficient use of clinical, educational, and family support resources in the community. Through a review of published and unpublished papers and extensive interviews with key individuals, the investigators will determine how successful links are formed with community-based services. Clinicians and health systems will receive practical guidance on connecting families to such services as well as case studies describing effective models around the country. Policymakers, meanwhile, will be informed of ways to promote and facilitate adoption of these models. The project's findings will be useful in establishing protocols and standards for systems that link pediatric care to related services for children and families.
