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.     

Changes in health plans serving Medicaid, 1993-1996

To better understand the Medicaid managed care market during a period of rapid change, we developed a new data set that links Medicaid enrollment data with health maintenance organization (HMO) industry data for 1993-1996 to analyze Medicaid enrollment in full-risk health plans. Nearly half of the Medicaid enrollees in a fully capitated managed care arrangement were in plans in which Medicaid makes up at least 75 percent of the total enrollment. In addition, the number of Medicaid-only plans has more than doubled since 1993. Commercial-based plans participated increasingly in Medicaid managed care during the period, yet more than half of the plans entering the Medicaid market were newly formed.     

Medicaid managed care in thirteen states

This study examines the recent expansion of Medicaid managed care from the perspective of the thirteen states in the Urban Institute's Assessing the New Federalism project. States are moving to managed care for Medicaid both to improve beneficiaries' access and to control the growth in program costs. However, we find that despite dramatic growth in enrollment during this decade, few states are enrolling the elderly or the disabled--the most expensive Medicaid beneficiaries. We also conclude that cost-savings objectives are often at odds with goals of contracting with mainstream plans and protecting safety-net providers.     

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.     

Beyond managing Medicaid costs: restructuring care

The apparent success of managed care plans in controlling medical costs has made the prospect of managed care for Medicaid recipients attractive for state health policy makers. However, because the principles upon which managed care was created do not apply to the most costly segments of the Medicaid population, efforts to address their needs through traditional managed care strategies are likely to be self-defeating. The Maryland Medicaid database was used to review and analyze the successes and failures of managed care Medicaid initiatives to date. This review led to the suggestion that the integration of specialized systems for specific subgroups of the Medicaid population into managed care, in conjunction with broader public policies, could lead to improved quality and lower costs.     

A dummy orbit for training in diagnostic procedures and laser surgery with enucleated eyes

OBJECTIVES: The purpose of this study was to analyze duration of coverage among new Medicaid enrollees. METHODS: The 1991 Survey of Income and Program Participation was used to examined the duration of coverage for individuals who did not have Medicaid in January 1991 and obtained coverage by May 1993. RESULTS: Of new Medicaid enrollees, 38% (90% confidence interval [CI] = 34%, 42%) remained covered 1 year later; 26% (90% CI = 21%, 31%) remained covered at 28 months. Of those older than 65 years, 54% (90% CI = 31%, 77%) retained Medicaid for 28 months, vs 20% (90% CI = 14%, 26%) of children. Of people who lost Medicaid, 54% (90% CI = 31%, 77%) had no insurance the following month. CONCLUSIONS: Almost two thirds of new Medicaid recipients lose coverage within 12 months. It is unlikely that Medicaid managed care will enhance continuity of care for new recipients.     

A longitudinal study of schoolchildren's experience in the North Carolina Dental Medicaid Program, 1984 through 1992

OBJECTIVES: This evaluation of a state Medicaid dental program describes dental treatment received, relates treatment needed to treatment received, and describes enrollment and use over an 8-year period. METHODS: Three databases were linked: (1) clinical records from a 1986/87 statewide epidemiological survey, providing data on treatment need; (2) Medicaid dental claims from 1984 through 1992, providing data on treatment received; and (3) Medicaid enrollment files from 1984 through 1992. RESULTS: Half of Medicaid-enrolled children never used dental services. Among users of dental services, 45% and 25% of children needed restorations in primary and permanent teeth, respectively. In this group, 29% had all needs met, 28% had needs partially met, and 43% had no needs met. Forty-six percent of children sought care for only 1 year. CONCLUSIONS: Federal guidelines for dental care are not met in this typical Medicaid population of short-term enrollees who use services sporadically. Programs should aim to increase use and ensure that all needed services, especially preventive procedures such as sealants, can be completed within the short period of time a child attends for care.     

Overview and implications of Medicaid managed care for people with developmental disabilities

The inclusion of people with developmental disabilities in managed care as part of general efforts by states to enroll and Medicaid recipients in such plans was reviewed. Managed care was defined and the processes by which managed care organizations deliver services were explained. Escalating costs and utilization were discussed as the primary reason for the shift to managed care. The use of Medicaid Section 1115 waivers by states to include Medicaid recipients was explored. The relation between acute health care and long-term care, and the utilization patterns in each, were briefly described. Finally, elements of managed care that are particularly important to people with developmental disabilities, such as care coordination, maintenance of quality, and individual and family support, were discussed.     

Psychologists' reactions to Medicaid managed care: Opinion and practice change after 1 year.

How do psychologists adapt over time to a new managed care program? Reactions of Iowan psychologists to a managed mental health care program for Medicaid recipients were examined. The program was generally perceived negatively, although perceptions improved over time. Psychologists in private practice decreased the proportion of Medicaid patients they treated. Psychologists who continued to treat Medicaid patients reported decreased levels of job autonomy and satisfaction. A new managed care program presents psychologists with difficult ethical decisions, in which the quality of care provided to clients must be weighed against the negative aspects of participating in a managed care program.

Medicaid managed care and community providers: new partnerships

Growing enrollment in managed care plans among Medicaid recipients represents a new market for these plans but presents challenges to those providers that traditionally have served this population. To continue serving Medicaid patients, community-based providers must develop contracts or other types of partnerships with Medicaid-contracting health plans. This paper reviews the challenges to such collaboration and discusses the practical issues that plans and community-based providers must resolve to develop productive working relationships. Keys to successful collaboration are identified. Ways in which federal and state governments can help the collaborative process are suggested.     

Medicare managed care: past, present, and future

Medicare managed care enrollment has mushroomed in the past few years, tripling from 1993 to 1997. The payment rates have allowed plans to offer valuable extra benefits to beneficiaries at little or no additional cost; employers have provided inducements for their retirees to enroll; and many of the new Medicare beneficiaries are already in managed care plans when they enter the program. The Balanced Budget Act of 1997 and other factors could cause enrollment trends to change in either direction. More kinds of plans, including physician service organizations and preferred provider organizations, may be more attractive; new educational efforts may make more beneficiaries aware of managed care plans; and employers may continue to move their retirees into managed care. On the other hand, lower than expected Medicare payment rates to the plans may reduce the additional benefits they offer; consumer dissatisfaction with managed care is growing; and employers are dropping retiree benefits altogether. The future of Medicare managed care is hard to predict.     

Medicaid managed care and the marketplace

In 1994 and 1995, Tennessee, Hawaii, Rhode Island, and Oklahoma began massive expansions of Medicaid managed care, growing from three health plans covering a few enrollees to 27 plans covering the great majority a year later. Some firms aggressively pursued expansion, while others had very limited business objectives. Although established insurers often dominated the Medicaid markets, newly developed firms, some provider-sponsored, were also important. Despite the relatively low Medicaid capitation rates in the 1996-97 period, Medicaid plans in three states had an average 1% net profit margin.     

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.     

How expensive is unlimited mental health care coverage under managed care?

OBJECTIVES: To study costs, access, and intensity of mental health care under managed care carve-out plans with generous coverage; compare with assumptions used in policy debates; and simulate the consequences of removing coverage limits for mental health care as required by the Mental Health Parity Act. DESIGN: Claims data from 1995 and 1996 for 24 managed care carve-out plans; all plans offered unlimited mental health coverage with minimal co-payments. OUTCOME MEASURES: Probability of care, intensity of care, and total costs broken down by service type and type of enrollee. RESULTS: Assumptions used in last year's policy debate overstate actual managed care costs by a factor of 4 to 8. In the plans studied, costs are lower owing to reduced hospitalization rates, a relative shift to outpatient care, and reduced payments per service. However, access to mental health specialty care increased (7.0% of enrollees) compared with the preceding fee-for-service plans (6.5%) or free care in the RAND Health Insurance Experiment (5.0%). Removing an annual limit of $25000 for mental health care, which is the average among plans currently imposing limits, will increase insurance payments only by about $1 per enrollee per year. Children are the main beneficiaries of expanded benefits. CONCLUSIONS: Concerns about costs have stifled many health system reform proposals. However, policy decisions were often based on incorrect assumptions and outdated data that led to dramatic overestimates. For mental health care, the cost consequences of improved coverage under managed care, which by now accounts for most private insurance, are relatively minor.     

Managed care and unintended pregnancy

This article assesses the adequacy of coverage of contraceptive services and supplies for US women in the various types of managed care plans, with special attention to Medicaid. Between 1993 and 1995, the percent of insured private-sector employees enrolled in managed care plans rose from 51% to 73%. By 1996, the health care of 40% of low-income Medicaid recipients was also under managed care administration. Although 84% of managed care plans cover oral contraceptives--a rate substantially higher than that for traditional indemnity plans, several logistic factors impede access to this and other reproductive health benefits. The requirement of preauthorization may delay access to care when timely presentation is essential to the prevention of unwanted pregnancy. Some plans restrict members to one visit per year with an obstetrician-gynecologist. Coordination of an enrollee's total health care through the primary care physician can raise confidentiality problems for those who seek sensitive reproductive health services. There are fewer restrictions on the access of Medicaid recipients to family planning providers and services, but treatment of sexually transmitted diseases may not be part of the reproductive health package. The explosion of managed care onto the US health care market has led to public sector regulation legislation--a process that is proceeding in a piecemeal rather than comprehensive way. Because of the importance of reproductive health care to the lives of women, communities, and the broader society, more systematic action on this front is essential.     

Mental health services in managed care: quality questions remain

Primary care physicians are often the professionals to whom older patients turn for advice about medical coverage in Medicare managed care health plans. To assist in this dialogue, these authors outline current characteristics and financial arrangements for psychiatric and mental health services in Medicare managed care. Advantages and disadvantages of Medicare managed care for enrollees with mental disorders are outlined. Mental health "carve-out" and "carve-in" models are defined, and questions are raised about the number of psychiatrists and other mental health care providers needed to provide appropriate care for a plan's enrollees.     

The impact of payor/provider type on health care use and expenditures among the frail elderly

OBJECTIVES: This study examined whether health care expenditures and usage by the frail elderly differ under three payor/provider types: Medicare fee for service, Medicare health maintenance organization (HMO), and dual Medicare-Medicaid enrollment. METHODS: In-home interviews were conducted among 450 frail elderly patients of a San Diego, Calif, health care system. Cost and use data were collected from providers. RESULTS: Analyses revealed no difference in total expenditures between fee-for-service and HMO enrollees, but Medicare-Medicaid beneficiaries' expenditures were 46.8% higher than those for HMO enrollees and 52.2% higher than those for the fee-for-service group. Fee-for-service participants were less than half as likely as HMO enrollees to have two or more hospital admissions, but hospital usage rates between those two payor/provider groups did not differ. Not were there payor/provider differences in access to home health care, but HMO home health care users received significantly fewer services than the others. CONCLUSIONS: The care provided to these HMO beneficiaries resulted in a combination of restricted home health use and higher multiple hospitalizations. This raises compelling questions for future research. For the dually enrolled, stronger cost containment may be required.     

Chemical synthesis of 15 beta-hydroxytestosterone and its derivatives using a (4-methoxyphenyl)methyl protecting group

This article describes the Community Nursing Organization, a federal health care model designed to provide specific ambulatory and outpatient services to medicare beneficiaries via a nurse managed delivery system under capitated financing. A primary nurse provider, working with the elderly client, family, physician, health care service providers, and community organizations, assesses the need for care and arranges for appropriate services. This nurse must also authorize payment of those services covered by the Community Nursing Organization (CNO). A 3-year demonstration project is currently under way. Findings at 1 year indicate that the system may have a positive effect on client health status.     

Some early lessons from the rise of managed behavioral health care in the United States

In the 1990s the United States has, because of an unacceptable surge in health care costs, made a revolutionary shift of the reimbursement process from fee-for-service to managed care's restricted, discounted and capitated payment approaches. Mental health care has for 150 years largely been subsidized by tax supported hospitals and clinics. Federal and state governments have recently instead begun to direct much of their monies to for-profit national managed mental health care companies. While efficiency has improved and the steep rise in costs has been eased, the major drawback of this change is a too enthusiastic focus on corporate profits. Since on the whole managed care organizations do not reinvest profits into medical education or research and may pull out of the health care business once the business is no longer so profitable, clinicians and academicians must become more successful in urging politicians and the citizenry to better manage managed care.
