We examined the effect of the expansion of Medicaid eligibility under the Affordable Care Act on health insurance coverage and labor supply of low‐educated and low‐income adults. We found that the Medicaid expansions were associated with large increases in Medicaid coverage, for example, 50 percent among childless adults, and corresponding decreases in the proportion uninsured. There was relatively little change in private insurance coverage, although the expansions tended to decrease such coverage slightly. In terms of labor supply, estimates indicated that the Medicaid expansions had little effect on work effort despite the substantial changes in health insurance coverage. Most estimates suggested that the expansions increased work effort, although not significantly.

The federal Strong Start for Mothers and Newborns initiative supported alternative approaches to prenatal care, enhancing service delivery through the use of birth centers, group prenatal care, and maternity care homes. Using propensity score reweighting to control for medical and social risks, we evaluated the impacts of Strong Start's models on birth outcomes and costs by comparing the experiences of Strong Start enrollees to those of Medicaid-covered women who received typical prenatal care. We found that women who received prenatal care in birth centers had lower rates of preterm and low-birthweight infants, lower rates of cesarean section, and higher rates of vaginal birth after cesarean than did the women in the comparison groups. Improved outcomes were achieved at lower costs. There were few improvements in outcomes for participants who received group prenatal care, although their costs were lower in the prenatal period, and no improvements in outcomes for participants in maternity care homes.

Objective. To estimate the effects of Medicaid managed care (MMC) programs on Medicaid enrollees' access to and use of health care services at the national level. Data Sources/Study Setting. 1991-1995 National Health Interview Surveys (NHIS) and a 1998 Urban Institute survey on state Medicaid managed care programs. Study Design. Using multivariate regression models, we estimated the effect of living in a county with an MMC program on several access and use measures for nonelderly women who receive Medicaid through AFDC and child Medicaid recipients. We focus on mandatory programs and estimate separate effects for primary care case management (PCCM) programs, health maintenance organization (HMO) programs, and mixed PCCM/HMO programs, relative to fee-for-service (FFS) Medicaid. We control for individual and county characteristics, and state and year effects.

No abstract

The effects of Medicaid managed care vary with the type of program, and policy makers should not expect programs that rely on PCCMs to have the same effects as those that incorporate mandatory HMO enrollment. Moreover, none of the program models had strong and consistent effects across the indicators of access and use that we considered.

This DataWatch examines the health insurance coverage of former welfare recipients who left welfare between January 1995 and mid-1997, using data from the 1997 National Survey of America's Families. Although the majority of women who left welfare were working, only 33 percent of these women obtained health coverage through their jobs. Rates of uninsurance increase with the number of months since leaving welfare and with declines in Medicaid coverage. A year or more after leaving welfare, 49 percent of women and 30 percent of children were uninsured.

Objectives:Medicaid pays for about half the births in the United States, at very high cost. Compared to usual obstetrical care, care by midwives at a birth center could reduce costs to the Medicaid program. This study draws on information from a previous study of the outcomes of birth center care to determine whether such care reduces Medicaid costs for low income women. Methods:The study uses results from a study of maternal and infant outcomes at the Family Health and Birth Center in Washington, D.C. Costs to Medicaid are derived from birth center data and from other national sources of the cost of obstetrical care. Results:We estimate that birth center care could save an average of $1,163 per birth (2008 constant dollars), or $11.6 million per 10,000 births per year. Conclusions:Medicaid is the leading payer for maternity services. As Medicaid faces continuing cost increases and budget constraints, policy makers should consider a larger role for midwives and birth centers in maternity care for low-risk Medicaid pregnant women.

Local community providers can play an important role in outreach and enrollment for Medicaid. Availability and cost of ESI constrain private coverage for Medicaid-eligible children. Policies that encourage offers of insurance coverage by employers, decrease premiums, and encourage adoption of managed care could have important positive effects on coverage for this population.
