Factors influencing survival after gamma knife radiosurgery for patients with single and multiple brain metastases

BACKGROUND: Significant changes are restructurng the U.S. health care delivery system. National health reform is now extending itself into the public sector. Increased health and medical costs by federal and state governments are forcing a reevaluation of major entitlement programs, especially Medicaid. METHODS/RESULTS: Because Medicaid is the single largest item in many state budgets, states are now enrolling Medicaid patients into managed and coordinated care arrangements as a means to control costs and increase access to care. HMOs are not only competing for private patients but also actively seeking the Medicaid population. Nationally, almost one-fourth of all Medicaid patients are now enrolled in managed care plans. Various models and approaches have been developed by individual states. CONCLUSIONS: Because managed care enrollment in the Medicaid program has increased substantially in recent years, selected services including vision care are no longer rendered by any practitioner willing to accept Medicaid fees. Freedom of choice is now restricted to pre-selected and panel practitioners participating with the managed care program. The rules, regulations, billing procedures, fees, and program requisites will differ under managed care programs. Private optometric practitioners must consider entering economic and organizational relationships and linkages that make them attractive to managed care organizations.

OBJECTIVES: To assess the likelihood of health care legislation in the forthcoming 105th Congress in 5 areas: health care coverage, tax and Employee Retirement Income Security Act (ERISA) policy, Medicaid, Medicare, and managed care. DESIGN: Informal, semistructured conversations that took place in the months prior to the 1996 elections. POPULATION: Congressional health staff and administration officials. OUTCOME MEASURES: Unofficial, off-the-record personal opinions. RESULTS: Health care coverage initiatives to benefit children and unemployed persons are likely to be proposed, but have little chance of enactment; children are seen as well provided for under current Medicaid law, the strong economy and high employment levels lower concern for unemployed issues, and the effort required to pass the Kassebaum-Kennedy legislation needs time to settle. Tax proposals, such as medical savings accounts (MSAs), and ERISA amendments have no constituency; also, the MSA demonstration in Kassebaum-Kennedy will forestall further action. Medicaid is far less an issue than in the previous Congress, because spending has fallen unexpectedly, the bitter fight over block grants makes them unlikely to be revisited, and the administration is likely to enhance state flexibility through waivers. Medicare will be the subject of substantial action to defer impending insolvency temporarily, but there is virtually no chance that definitive long-term solutions will be enacted even though the underlying fiscal problems are thoroughly understood and recognized. Managed care will be the venue for numerous proposals designed to address specific consumer and quality issues. CONCLUSIONS: Four bitter years of fighting over health care issues has raised awareness of the problems, but has produced a political chemistry that is too rancorous to permit passage of significant legislation in the near future.     

Medicaid policy: Psychology's overlooked agenda.

Although psychologists are recognized as autonomous providers under almost every major federal health care initiative, they are not federally recognized as such under Medicaid because of Medicaid's unique federal–state partnership. State-by-state information on the access to psychologists under state Medicaid regulations are presented. As the move toward national health care reform becomes increasingly evident in the 1990s, psychologists have the responsibility and the opportunity to design innovative, behaviorally oriented health care delivery models in response to the national concerns of adequate coverage, access, and quality care. To do this, psychology as a profession must gain formal recognition under the various state Medicaid plans, either on a state-by-state basis or by way of federal mandates (as it was achieved by professional nursing).

A monoarthritis model in rabbits induced by repeated intra-articular injections of lipopolysaccharide

In recent years, states have increasingly turned to managed care arrangements for financing and delivering health services to Medicaid beneficiaries. In 1996, approximately 40% of all Medicaid recipients were enrolled in some form of managed care. The rapid escalation of managed care in this population has been fueled by states' desire to slow the growth of Medicaid expenditures and by the trend toward managed care enrollment in the private health insurance industry. The effect of managed care on cost containment in the Medicaid program may be limited, however, because 85% to 90% of Medicaid managed care enrollees are women of childbearing age and children, who together account for 69% of Medicaid recipients, but only 26% of program costs. Nonetheless, the increase in managed care enrollment in this population may have a profound impact on health service delivery and health outcomes for U.S. children, approximately 20% of whom received health benefits through the Medicaid program in 1995. In the future, the proportion of Medicaid-eligible children enrolled in managed care will likely increase as a result of recent legislation that relaxed the requirement that states seek federal approval prior to mandating managed care enrollment for Medicaid beneficiaries. More states are relying on fully capitated arrangements as the preferred type of managed care for Medicaid recipients, despite the relative lack of experience many of these plans have in serving this low-income population. Moreover, managed care organizations have few incentives to enroll chronically or disabled children with higher-than-average expected costs. Without mechanisms in place that adequately adjust capitated rates to account for these higher-cost enrollees, managed care organizations may lose money, and children with the greatest health care needs may be underserved. As mandatory managed care enrollment for Medicaid recipients increases nationwide, states should carefully monitor changes in program costs and quality as well as implications for the delivery of pediatric health services and health outcomes.     

Time to nursing home admission for persons with Alzheimer's disease: the effect of health care system characteristics

OBJECTIVE: To study the influence of state health care system characteristics on time to nursing home admission (NHA) for persons with Alzheimer's disease (AD). METHOD: Up to nine years of Consortium to Establish a Registry for Alzheimer's Disease (CERAD) data on 639 non-Latino White individuals were merged with longitudinal data from the 28 states in which the CERAD participants resided. The state variables reflected characteristics of each state's long-term care (LTC) system, including Medicaid LTC spending practices and the supply of LTC providers. Cox Proportional Hazards Models with time-varying covariates were used to evaluate the risk factors associated with time to NHA. RESULTS: There was differential influence of state variables by marital status. For unmarried non-Latino White persons with AD, a higher percentage of Medicaid LTC spending on home and community-based services (HCBS) was significantly associated with a longer time to NHA. For married persons, a greater number of home health agencies was associated with a longer time to NHA. Other associations also varied by marital status. CONCLUSION: Study findings support the utility of targeted continued expanded provision of HCBS by states and provide a basis for future research regarding the impact of changing state health care systems on LTC utilization for persons with AD.     

Is Medicaid pronatalist? The effect of eligibility expansions on abortions and births

CONTEXT: Income thresholds for Medicaid eligibility for pregnant women were raised in two phases between 1987 and 1991. During roughly the same period, the U.S. fertility rate rose and the abortion rate declined; changes were particularly marked among young women, raising the possibility that fertility increases were related to Medicaid expansions. METHODS: Pooled time-series cross-section regressions were used to examine the effects of the Medicaid eligibility expansions in 15 states on rates of abortions and births among unmarried women aged 19-27 with 12 or fewer years of schooling. Abortion data came from the National Center for Health Statistics or state health departments and were aggregated by women's age, race, marital status and schooling; data on births were from national natality tapes. RESULTS: The Medicaid expansions were associated with a 5% increase in the birthrate among white women, but did not influence the rate among black women. Overall, no effect on the abortion rate was evident, but in analyses restricted to a subsample of eight states with the most complete abortion data, the rate among white women showed a significant decline after the second phase of expansions. CONCLUSIONS: Subsidized health care for low-income pregnant women in these 15 states may have encouraged white women to have more children than they would have without coverage.     

Spending-down to Medicaid in the nursing home and in the community. A longitudinal study from Monroe County, New York

Medicaid spend-down continues to be of considerable interest in public policy discussions regarding long-term care financing reforms. Yet, "measuring" of spend-down has been difficult because of data limitations. This study focuses on patterns of spend-down affecting those who become Medicaid eligible both in nursing homes and in the community. The study uses a longitudinal, person-specific, merged Medicare and Medicaid claims and eligibility file constructed for Monroe County, New York. The analyses show that 27% of those who enter nursing homes as private pay can be expected to spend-down to Medicaid while in a nursing home. The spend-downers remain in nursing homes for a prolonged time, with 63% staying for more than 3 years. On admission, spend-downers appear somewhat more likely than those who remained private pay or Medicaid throughout to have been less disabled in terms of activities of daily living (ADL). The community-based spend-down group is larger, younger, and more heavily represented by those who are poor or marginally poor, than the nursing home-based spend-down population. Their spend-down to Medicaid appears to have been triggered principally by the cost of acute medical care not covered by Medicare or another third-party payer. It is this population of the elderly that would have been the principal beneficiary of the short-lived 1989 Medicare Catastrophic Coverage Act. The results of this study indicate that neither the existing private long-term care insurance policies nor the currently circulating public coverage proposals alone are sufficient to protect older persons, at risk of spend-down to Medicaid, from impoverishment. Effective long-term care financing reform will need to create partnerships between public and private insurance, rather than look at them as competing options.     

Health care in the 105th Congress: A hopeful look forward.

Addresses the issue of health care reform by both reviewing events of the past few years up to and including the 104th Congress and by discussing issues of health care reform facing the 105th Congress. Issues discussed include Medicare and Medicaid, insurance reform, the uninsured, quality and consumer protection, and long-term care.

State health care reforms: how they affect children and adolescents with emotional disorders and their families

This article reports on the Health Care Reform Tracking Project, a national study designed to describe and analyze state health care reforms and their impact on children and adolescents with emotional disorders and their families. It summarizes the results of the baseline survey of states conducted in 1995, exploring the nature and extent of the reforms in which states are engaged, most of which involve applying managed care technologies to their Medicaid programs. Trends across states are identified with respect to mental health service delivery, particularly with respect to children and adolescents. The article concludes with a discussion of issues and concerns related not only to mental health service delivery for children and adolescents with emotional disorders and their families but also to the systems of care that have been developing over the past decade to serve them. Some of these concerns include the lack of pilots or demonstrations, limited mental health coverage in some reforms, the lack of integration between mental health and substance abuse systems, the lack of special provisions for children, the need for more reliable bases for deriving capitation rates, the limited incorporation of systems of care, the need to incorporate interagency treatment planning and service delivery approaches, the lack of outcome measures specific to and appropriate for children, and the need for greater family involvement in the planning and implementation of these reforms.     

Managed care and reproductive health

Managed care poses special challenges to midwives providing reproductive health care. This is owing to the sensitive nature of issues surrounding reproductive health and aspects of managed care that may impede a woman's ability to obtain continuous, confidential, and comprehensive care from the provider of her choice. Variations across payers (ie, Medicare, Medicaid, and commercial insurers) regarding covered benefits and reimbursement of midwifery services also may create obstacles. Furthermore, some physicians and managed care organizations are embracing policies that threaten the ability of midwives to function as primary health care providers for women. Despite these hurdles, midwives have the potential to remain competitive in the new marketplace. This article underscores the importance of being knowledgeable about legislation and policy issues surrounding the financing of midwifery services, quality performance measurement for HMOs as they pertain to reproductive health, and discussions regarding which clinicians should be defined as primary care providers.     

Carving-out mental health benefits to Medicaid beneficiaries: a shift toward managed care

Several states have designed and implemented innovative programs for Medicaid beneficiaries that carve-out the provision of mental health from general health care. This paper describes several such programs and outlines the choices states face in designing these services. Major decisions include the selection of a public or private agency, how that agency is chosen, reimbursement schemes, eligibility criteria, and benefits to be covered. While carve-out programs have yielded initial savings, more research is needed on their effect on quality of care and general health care costs.     

Psychotherapy research on Medicaid in Hawaii.

Describes the complex organizational and social conditions for conducting psychotherapy research in a state Medicaid program. Comparative data are offered on service delivery and utilization in Medicaid, the Civilian Health and Medical Program of the Uniformed Services, and the dominant employee health plan in Hawaii. It is suggested that the reporting of these data has led to extended coverage of psychologists under Hawaii Medicaid laws. The major overlap in types of procedures used by psychologists and psychiatrists and some indications of the impact of the extended coverage of psychologists on Medicaid health care costs are described.

Promoting choice: lessons from managed Medicaid

Drawing on the education, enrollment, and assignment experiences of seven states with mandatory Medicaid managed care programs, this paper finds that the vast majority of enrollees will choose their own health plan if the system is explicitly designed with this in mind (as in Minnesota and Oregon). These experiences provide lessons on ways to 1) align program design with state priorities; (2) increase the level of choice (by coordinating enrollment and eligibility processes, broad-based educational strategies, and personalized attention); (3) improve the quality of choice; and (4) design state contracting processes to support choice and continuity of care.     

Prader-Willi and Angelman syndromes. Disorders of genomic imprinting

OBJECTIVE: To develop estimates of state Medicaid expenditures attributable to smoking for fiscal year 1993. METHODS: The smoking-attributable fractions (SAFs) of state Medicaid expenditures were estimated using a national model that describes the relationship between smoking and medical expenditures, controlling for a variety of sociodemographic, economic, and behavioral factors. RESULTS: In fiscal year 1993, the SAF for all states (all types of expenditures) was 14.4%, with a range from 8.6% in Washington DC to 19.2% in Nevada. On average, SAFs ranged from a low of 7.9% for home health services expenditures to 21.7% for hospital expenditures. An estimated total of $12.9 billion of fiscal year 1993 Medicaid expenditures was attributable to smoking. The relative error of this estimate was 40.3%. CONCLUSIONS: Cigarette smoking accounts for a substantial portion of annual state Medicaid expenditures, with considerable variation among states. The range in expenditures among the states is due to differences in smoking prevalence, health status, other socioeconomic variables used in the model, and the level and scope of the Medicaid program.     

Comparison of public/private health care insurance parameters for independent psychological practice.

Managed care cost-cutting strategies are more prevalent in the private (employer provided) than public (Medicare/Medicaid) health care sectors. The main organizational managed care strategy pertaining to the independent practice of psychology has been the separation of the administration of mental from medical health care though behavioral health carve-outs. These organizations typically offer lower reimbursement rates and have greater preauthorization requirements than non-managed care public plans for the same psychological service. Dispute resolution in the private sector involves lawsuits and state consumer protection programs while public plans utilize internal review and are subject to investigations of provider billing fraud and abuse. Behavioral health carve-outs have reduced mental health care utilization rates with unknown effects upon outcome. There is some evidence that psychologists have chosen to limit practice within the private sector, but national data on the overall effect is lacking.

A critical analysis of studies of state drug reimbursement policies: research in need of discipline

Concerns over pharmaceutical costs and appropriateness of medication use have led state Medicaid programs to restrict drug reimbursement. This article critically reviews 20 years of research on cost sharing, drug reimbursement limits, and administrative limitations on access to particular drugs via formularies, category exclusions, or prior authorization requirements; evaluates their methodological rigor; summarizes the state of current knowledge; and proposes future research directions. Drug reimbursement caps and modest cost sharing can reduce the use of both essential and less important drugs in Medicaid populations; severe reimbursement caps may precipitate serious unintended effects. Limitations on access to particular drugs can cause both rational and irrational drug substitution effects; it is unclear whether such limits reduce expenditures either for drugs or for overall health care.     

Rethinking psychology and the schools: Implications of recent national policy.

Social reforms affecting society often are played out in America's schools. Within the past 3 years, the federal government and many states have passed massive social reforms, all of which affect schools, children, and families. This article explores 2 converging reform movements: education and health care reform. Education reform, which is addressed nationally in the Goals 2000: Educate America Act of 1994, the Improving America's Schools Act of 1994, the School-to-Work Opportunities Act of 1994, and the pending reauthorization of the Individuals With Disabilities Education Act (1994), is producing dramatic transformations at federal, state, and local levels. Although comprehensive national health care legislation has failed to gain passage, many states and national groups are promoting schools as health service delivery sites. Thus, social reform movements in education and health care are converging within the single social institution that touches the lives of every American citizen—the schools. This article explores the challenges and opportunities for psychology in addressing social reforms associated with the schools. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The role of Medicaid in ensuring children's access to care

CONTEXT: Congress enacted a series of laws beginning in the mid 1980s to expand Medicaid eligibility for children, especially those in poor families. As a result, Medicaid enrollment of children has nearly doubled over the past decade. OBJECTIVE: To assess the effectiveness of Medicaid in improving access to and use of health services by poor children. DESIGN: Analysis of cross-sectional survey data from the 1995 National Health Interview Survey. Poor children with Medicaid were compared to poor children without insurance and nonpoor children with private insurance. SETTING AND PARTICIPANTS: A total of 29711 children younger than 18 years (3716 poor children with Medicaid, 1329 poor children without insurance, 14609 nonpoor children with private insurance, and 10057 children with other combinations of poverty and insurance status) included in a nationally representative stratified probability sample of the US noninstitutionalized population. MAIN OUTCOME MEASURES: Usual source of care, access to a regular clinician, unmet health needs, and use of physician services. RESULTS: Poor children with Medicaid compared to poor children without health insurance experienced superior access across all measured dimensions of health care, including presence of a usual source of care (95.6% vs 73.8%), frequency of unmet health needs (2.1 % vs 5.9%), and use of medical services (eg, > or =1 physician contact in past year) (83.9% vs 60.7%). Poor children with Medicaid compared to nonpoor children with private insurance used similar levels of physician services (83.9% vs 84%), but were more likely to have unmet health needs (2.1 % vs 0.6%) and were less likely to have a usual source of care (95.6% vs 97.4%). CONCLUSION: Medicaid is associated with improvements in access to care and use of services. However, there remains room for improvement when Medicaid is judged against private health insurance. The Balanced Budget Act of 1997 contains several Medicaid provisions that could stimulate further improvements in access for poor children.     

The reforming states group and the promotion of federalism

Since 1991, leaders in health policy from the legislative and executive branches of state government have come together, with financial support and staff collaboration from the Milbank Memorial Fund, to share their experiences and to work on practical solutions to pressing health care problems. What began with a handful of states at the forefront of health reform is now the Reforming States Group (RSG), a bipartisan, voluntary association that includes leaders from over 40 states. This article describes the origins, history, and future prospects of the RSG.
