The State Children's Health Insurance Program

PURPOSE OF REVIEW: The State Children's Health Insurance Program expanded public health insurance to children who are ineligible for Medicaid yet unable to afford private health insurance. The program was a natural experiment, offering the opportunity to study the effects of expanding health insurance to a large population of children who would otherwise be uninsured. The State Children's Health Insurance Program is reviewed in the context of program goals, evaluation dimensions, past and current findings, and future directions. The studies and findings fall into five dimensions: (1) outreach/enrollment/uptake and profile of enrollees, (2) impact on insurance coverage and uninsured rates, (3) coverage dynamics, (4) impact on outcomes, and (5) costs. RECENT FINDINGS: Older studies focused on outreach, enrollment, characteristics of enrollees, disenrollment, and coverage dynamics. Current studies report the impact of the program on outcomes--including access to care, quality, satisfaction, unmet need, and health outcomes--for the overall population of children and for vulnerable subgroups, including racial and ethnic minorities and children with chronic illness. A smaller number of studies address costs. SUMMARY: The State Children's Health Insurance Program is evolving with demonstrated successes and areas for improvement. This information can enhance practicing pediatricians' understanding of barriers that face low-income children and families in seeking care for their children, can offer insight into what health insurance can and cannot do in terms of ameliorating those barriers, can provide insight into the prior experiences and current medical needs that a new enrollee in the program might have at the first visit to a practitioner, and can illuminate the challenges that low-income children and families may face in obtaining and maintaining health insurance coverage.
