The evolution in medical technology for children with special health care needs has been accompanied by an evolution in concepts of care. Broadened diagnostic categories, comprehensive concern for the whole child, and coordinated services that are family-centered and community-based have become part of the national agenda. During the 1980s this agenda was advanced both by congressional action and by joint activities of the U.S. Public Health Service and the private sector. Much remains to be accomplished. Increased parent participation and activism, an integral part of the future, will require vigilant nurturing and support.
