Are adults benefiting from state coverage expansions?

This study provides a rigorous evaluation of state efforts to expand insurance coverage in California, Massachusetts, New Jersey, and Wisconsin. Overall, parents in Wisconsin and parents and childless adults in Massachusetts experienced the largest expansions in public coverage, with few, if any, offsetting reductions in private coverage. In contrast, the coverage expansions for parents in California and New Jersey led to increased enrollment, but often at the expense of private coverage. Because constraints on state resources are putting pressure on expansion efforts, we find evidence that cutbacks will place more adults at risk of being uninsured.

Toward universal coverage in Massachusetts.

This paper presents several options designed to help the Commonwealth of Massachusetts move to universal health insurance coverage. The alternatives all build upon a common base that includes an expansion of the Medicaid program, income-related tax credits, a purchasing pool, and government-sponsored reinsurance. These measures in themselves would not yield universal coverage, nor would an employer mandate by itself. We show that an individual mandate, and an employer mandate combined with an individual mandate, both would yield universal coverage with a relatively small increase in government costs relative to state gross domestic product and current health spending. The cost of an employer mandate--with a "pay or play" design--is sensitive to the payroll tax rate and base, the number and kind of exemptions, and whether workers whose employers "pay" receive discounts when they purchase health insurance. The development of these alternatives and their analyses contributed to the eventual health care compromise that emerged in Massachusetts in April 2006.

National estimates of the effects of mandatory Medicaid managed care programs on health care access and use, 1997-1999.

OBJECTIVE: We sought to explore how mandatory Medicaid managed care programs affect access to care and use among full-year Medicaid beneficiaries not receiving SSI or Medicare. RESEARCH DESIGN: We used data from the 1997 and 1999 National Survey of America's Families. To establish what Medicaid beneficiaries' access and use would have been in the absence of Medicaid managed care (MMC) and to control for unobserved county differences, we estimated difference-in-difference models using a comparison group of privately insured individuals who we would not expect to be affected by MMC. RESULTS: We found weaker effects of MMC programs for children than adults. The strongest result is that mandatory HMO programs lower the probability of Medicaid adults using emergency rooms, when implemented alone or in combination with Primary Care Case Management (PCCM) programs. PCCM programs reduced the number of visits among adults but had little effect on other measures of access and use. There was less preventive care in mandatory HMO counties for women, suggesting that the federally required external quality review may be appropriate. CONCLUSION: 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.

The effect of Medicaid payment generosity on access and use among beneficiaries.

OBJECTIVE: This study examines the effects of Medicaid payment generosity on access and care for adult and child Medicaid beneficiaries. DATA SOURCE: Three years of the National Surveys of America's Families (1997, 1999, 2002) are linked to the Urban Institute Medicaid capitation rate surveys, the Area Resource File, and the American Hospital Association survey files. STUDY DESIGN: In order to identify the effect of payment generosity apart from unmeasured differences across areas, we compare the experiences of Medicaid beneficiaries with groups that should not be affected by Medicaid payment policies. To assure that these groups are comparable to Medicaid beneficiaries, we reweight the data using propensity score methods. We use a difference-in-differences model to assess the effects of Medicaid payment generosity on four categories of access and use measures (continuity of care, preventive care, visits, and perceptions of provider communication and quality of care). PRINCIPAL FINDINGS: Higher payments increase the probability of having a usual source of care and the probability of having at least one visit to a doctor and other health professional for Medicaid adults, and produce more positive assessments of the health care received by adults and children. However, payment generosity has no effect on the other measures that we examined, such as the probability of receiving preventive care or the probability of having unmet needs. CONCLUSIONS: Higher payment rates can improve some aspects of access and use for Medicaid beneficiaries, but the effects are not dramatic.

Characteristics of occasional and frequent emergency department users: do insurance coverage and access to care matter?

OBJECTIVE: The objective of this study was to explore how insurance coverage, access to care, and other individual characteristics are related to the large differences in emergency department (ED) use among the general population. MATERIALS AND METHODS: We used the 1997 and 1999 National Survey of America's Families, a nationally representative sample. People were classified into 3 ED use levels based on the number of visits over the 12 months before the survey: non-ED users (zero visits), occasional users (1 or 2 visits), or frequent users (3 or more visits). We used a multinomial logit model to estimate the effect of insurance status and other factors on levels of ED use, and to compute the odds ratios of being occasional and frequent users as opposed to nonusers among various subpopulations. RESULTS: People in fair/poor health are 3.64 times more likely than others to be frequent ED users as compared with nonusers. The uninsured and the privately insured adults have the same risk of being frequent users, but publicly insured adults are 2.08 times more likely to be frequent users. Adults who made 3 or more visits to doctors are 5.29 times more likely to be frequent ED users than those who made no such visits. CONCLUSION: The uninsured do not use more ED visits than the insured population as is sometimes argued. Instead, the publicly insured are overrepresented among ED users. Frequent ED users do not appear to use the ED as a substitute for their primary care but, in fact, are a less healthy population who need and use more care overall.

Health service access, use, and insurance coverage among American Indians/Alaska Natives and Whites: what role does the Indian Health Service play?

OBJECTIVES: We compared access and utilization of health services among American Indians/Alaska Natives (AIANs) with that among non-Hispanic Whites. METHODS: We used data from the 1997 and 1999 National Survey of America's Families to estimate odds ratios for several measures of access and utilization and the effects of Indian Health Service (IHS) coverage. RESULTS: AIANs had less insurance coverage and worse access and utilization than Whites. Over half of low-income uninsured AIANs did not have access to the IHS. However, among the low-income population, AIANs with only IHS access fared better than uninsured AIANs and as well as insured Whites for key measures but received less preventive care. CONCLUSIONS: The IHS partially offsets lack of insurance for some uninsured AIANs, but important needs were potentially unmet.

MassHealth succeeds in expanding coverage for adults.

This study provides the first rigorous evaluation of the impacts of MassHealth, Massachusetts' ambitious effort in the late 1990s to expand coverage to the entire low-income population. We find clear evidence that MassHealth led to an expansion of insurance coverage relative to what was happening to similar populations in comparison states. The success of MassHealth provides support for the value of investing in ambitious new state efforts to find effective strategies to reach the remaining uninsured populations. While current budget shortfalls have forced many states, including Massachusetts, to scale back their expansion efforts, the current economic downturn is not permanent. Understanding the impacts of the expansion efforts in Massachusetts adds to the base of knowledge that will be critical for guiding states when the economy recovers and the resources needed for expansion again become available.

Has Medicaid managed care affected beneficiary access and use?

This paper uses data from the 1997 National Survey of America's Families to examine the effects of the various forms of mandatory Medicaid managed care on access and use among beneficiaries not receiving Supplemental Security Income or Medicare benefits. The results show that mandatory health maintenance organization (HMO) programs have had a positive impact on both children and adults, particularly when compared to Medicaid fee-for-service plans. We observed less dependence on emergency rooms as a usual source of care, a greater probability of visiting a doctor and, for children, greater use of preventive care. In contrast, mandatory primary care case management plans (PCCM) provided some benefits to children, but appeared to have very little impact on adult Medicaid beneficiaries. Mandatory programs that use both HMOs and PCCM produced mixed results. With the exception of mandatory HMO programs, discrepancies in access and use continue to exist between Medicaid managed care enrollees and low-income privately insured people.

Why is there state variation in employer-sponsored insurance?

Using the National Survey of America's Families in 1997 and 1999, we investigate the sources of variation in employer-sponsored health insurance across states. We find that demographics and family characteristics (such as race/ethnicity and citizenship status), individual employment characteristics (such as firm size and labor-force attachment), and local labor market characteristics (such as unionization) consistently explain the relative position of all of the states with either high or low rates of employer coverage. Income plays a smaller role in explaining the state variation but is still an important determinant, especially among states whose average income is far from the national average.

Changes in medicaid physician fees, 1998-2003: implications for physician participation.

After slow growth during much of the 1990s, Medicaid physician fees increased, on average, by 27.4 percent between 1998 and 2003. Primary care fees grew the most. States with the lowest relative fees in 1998 increased their fees the most, but almost no states changed their position relative to other states or Medicare. Physicians in states with the lowest Medicaid fees were less willing to accept most or all new Medicaid patients in both 1998 and 2003. However, large fee increases were associated with primary care physicians' greater willingness to accept new Medicaid patients.

Three years of state fiscal struggles: how did Medicaid and SCHIP fare?

During 2003-05, states faced some of the largest budget shortfalls since World War II. With a focus on Medicaid and SCHIP, we examine budget decisions in eight states during this period. Increasing Medicaid enrollment because of the economic down-turn and rising health care costs compounded state budget shortfalls as state revenues dropped; problems peaked in 2004. States, however, were reluctant to confront their budget deficits as long-term problems and implemented a variety of one-time revenue strategies and spending reductions that push fiscal problems into the future. The arrival of federal fiscal relief in late 2003 helped states avoid deeper cuts but did not eliminate cutbacks.

Physician-owned specialty hospitals: a market signal for Medicare payment revisions.

Jean Mitchell's findings show that physician-entrepreneurs respond to financial incentives and take advantage of variations in profitability within Medicare's hospital payment system. The growth of physician-owned specialty hospitals can be seen as the reflection of parallel growth in profit opportunities. As Medicare plans to do, payments should be revised to squeeze out excess profits. Prohibiting physicians' use of hospitals they own might be unnecessary and could make it harder to identify future distortions in Medicare prices. If squeezing out excess profits threatens general hospitals' social missions, then new and explicit ways of identifying and funding social missions must be found.
