The State Children's Health Insurance Program (CHIP) was designed in 1997 to support working families by providing affordable, quality health coverage for their children in an efficient, effective, and coordinated way. This report examines the progress made in implementing CHIP nationwide. Information sources included the following: (1) federal data and reports on CHIP and Medicaid by Department of Health and Human Service agencies and the General Accounting Office; (2) state CHIP plans and reports; (3) reports and technical materials by national organizations; and (4) published research in peer-reviewed journals. Among the main findings of the report are the following: (1) every state and the District of Columbia have implemented a version of CHIP, with extensive state differences in plans; (2) rankings by state on their progress in increasing coverage were based on CHIP enrollment alone and CHIP and Medicaid enrollment combined; (3) the top 10 states, based on combined CHIP and Medicaid enrollment, were Alaska, Massachusetts, Maryland, New York, Louisiana, Maine, Missouri, Nebraska, North Carolina, and Arkansas; and (4) states with higher rankings generally adopted streamlined application and enrollment procedures early, had visible leadership from key state officials, and supported aggressive, community-based outreach. The report makes recommendations to increase enrollment and coverage of uninsured children in several areas, including coverage, eligibility, ease of enrollment, improved outreach, continuous enrollment, program coordination and integration, cultural competence, immigrant children, provider participation, accountability, information technology, and family coverage. Web sites and additional resources are appended. (Contains 79 references.) (KB)
