As reauthorization of the State Children’s Health Insurance Program (SCHIP) looms, we examine the program’s first decade and identify changes needed so that SCHIP can better serve its target population. We conclude that by many objective standards, SCHIP has been a success, but the challenge will be to maintain and build upon that success. Critical issues include the level and structure of federal funding; the continued problem of uninsurance among low-income children; the lack of information on quality, access, and costs; and whether SCHIP can serve as the foundation for addressing broader health care needs among low-income families.

This article examines experiences under Medicaid and the State Children's Health Insurance Program (SCHIP), drawing on surveys of over 3,000 enrollees in California and North Carolina in 2002. In both States, Medicaid enrollees were less likely than SCHIP enrollees to have parents who were covered by employer-sponsored insurance (ESI). With the exception of dental care and provider perceptions, access experiences were fairly comparable across the two programs, despite differences in the characteristics of the children served by the two programs. Relative to being uninsured, Medicaid enrollment was found to improve access to care along a number of different dimensions, controlling for other factors. Furthermore, this study emphasizes the need for continued evaluation of access to care for both programs.

This study examines the effects of new and higher premiums on SCHIP enrollment in Kansas, Kentucky, and New Hampshire—three states that implemented premium changes in 2003. We used state administrative enrollment records from 2001 to 2004–2005 to track changes in total caseloads, new enrollments, and disenrollment timing in premium-paying categories of SCHIP before and after the premium changes were implemented. Premium hikes were associated with lower caseloads in all three states and with earlier disenrollment in Kentucky and New Hampshire. Premium increases appeared to have greater disenrollment effects for lower-income children in New Hampshire and for nonwhite children in Kentucky.

This study uses 2000 to 2004 Current Population Survey data to examine the effects of public premiums on the insurance coverage of children whose family incomes are between 100% and 300% of the federal poverty level. The analysis employs multinomial logistic models that control for factors other than premium costs. While the magnitude of the estimated effects varies across models, the results consistently indicate that raising public premiums reduces enrollment in public programs, with some children who forgo public coverage having private coverage instead and others being uninsured. The results indicate that public premiums have larger effects when applied to lower-income families.

Objectives. We examined the ways in which levels of preventive dental care and unmet dental needs varied among subgroups of low-income children. Methods. Data were drawn from the 2002 National Survey of America’s Families. We conducted bivariate and multivariate analyses, including logistic regression analyses, to assess relationships between socioeconomic, demographic, and health factors and receipt of preventive dental care and unmet dental needs. Results. More than half of low-income children without health insurance had no preventive dental care visits. Levels of unmet dental needs among low-income children who had private health insurance coverage but no dental benefits were similar to those among uninsured children. Children of parents whose mental health was rated as poor were twice as likely to have unmet dental needs as other children. Conclusions. Additional progress toward improving the dental health of low-income children depends on identifying and responding to factors limiting both the demand for and the supply of dental services. In particular, it appears that expanding access to dental benefits is key to improving the oral health of this population.

Understanding the impacts of Medicaid managed care on pregnant women is critical because Medicaid covers more than a third of all births nationally, many under managed care arrangements. We sought to examine the impacts of mandatory Health Maintenance Organization (HMO) enrollment on prenatal care use, smoking, and birth weight for Medicaid-covered pregnant women in Ohio. Impact estimates are derived from a pre-post design with a comparison group, using Ohio birth certificate data linked to Medicaid enrollment files. Between April 1993 and April 1995 is the baseline period and October 1997 to June 1998 is the post-period. The treatment group consists of deliveries in 6 counties that implemented mandatory HMO enrollment in the mid 1990s; the comparison group consists of deliveries in 4 counties with voluntary HMO enrollment. Medicaid-covered deliveries to 24,799 non-Hispanic white women with no college education living in Ohio. Seven outcomes are analyzed: first trimester care; last trimester or no care; adequate prenatal care; inadequate prenatal care; smoking during pregnancy; and birth weight. Our findings indicate that mandatory HMO enrollment in Ohio's Medicaid program had positive effects on prenatal care and led to reductions in maternal smoking. No effects were found on birth weight. Even with the improvements related to Medicaid managed care, rates of inadequate prenatal care and maternal smoking remain relatively high. Addressing the underlying risk factors that are facing poor women and further expanding public programs may be critical to achieving further progress.

This paper examines successes and shortcomings of the State Children’s Health Insurance Program (SCHIP). SCHIP is a source of coverage for millions of children, improving their access to health care and sparking innovation in program design and improvements in Medicaid. However, SCHIP adds to the complexity of the insurance system and introduces new inequities in access to insurance; it is imperfectly targeting eligible children who are uninsured; and its financing is problematic because of the block-grant funding structure and use of SCHIP funds to cover adults. These issues need to be addressed during the SCHIP reauthorization process.
