Methods of reducing the financial risk of physicians under capitation.

In today's rapidly changing medical marketplace, managed care plans are not the only entities assuming risk for the care of enrollees through capitation. Increasingly, managed care plans are transferring this risk to their primary care and specialty physicians by paying them on a fully or partially capitated basis. Although capitation provides a strong incentive for physicians to provide cost-effective care, there are concerns that capitation may place some physicians at considerable financial risk. Our purpose is to familiarize physicians with issues they will want to consider when they evaluate capitation options and methods that are available to reduce their financial risk. Specifically, we analyze 3 issues: the range of services that are capitated, who accepts the risk, and size of patient panel. We conclude with a discussion of 3 methods for reducing or limiting risk--reinsurance, "carve outs," and risk adjustment.

Y2 receptors for neuropeptide Y in the nucleus of the solitary tract mediate depressor responses.

In anesthetized, spontaneously breathing rats, microinjections of selective agonists of neuropeptide Y (NPY) receptor subtypes were made into the medial region of the caudal nucleus of the solitary tract (NTS) at the level of the area postrema. This region of the rat NTS exhibits very high densities of NPY binding sites. Microinjections of the long C-terminal NPY fragment, NPY(13-36), a selective agonist at Y2 receptors, into the caudal NTS elicited pronounced, dose-related reductions in blood pressure and respiratory minute volume. Moreover, the specific pattern of cardiorespiratory responses elicited by NPY(13-36) was remarkably similar, over approximately the same dosage range, with the cardiorespiratory response pattern elicited by intact NPY. In contrast to the potent NTS-mediated responses evoked by NPY(13-36), similar microinjections conducted with either NPY(26-36), an inactive C-terminal NPY fragment, or [Leu31,Pro34]NPY, a NPY analog with specific agonist properties at Y1 receptors, into the same caudal NTS sites did not appreciably affect cardiorespiratory parameters even at 10-20-fold higher dosages. The present results with selective agonists for NPY receptor subtypes suggest that the depressor responses and reductions in minute volume elicited by microinjections of intact NPY and NPY(13-36) were mediated by Y2 receptors in the caudal NTS, likely distributed at presynaptic sites in the medial region of the subpostremal NTS.

The costs of children with sickle cell anemia: preparing for managed care.

PURPOSE: To anticipate the clinical challenges and financial risks facing physicians and managed care organizations who care for children with chronic illnesses, such as sickle cell anemia (SCA), under capitated managed care arrangements. PATIENTS AND METHODS: A cross-sectional study based on claims data from the Washington State Medicaid Program (WSMP) and the Federal Employees Health Benefits Program (FEP). Expenditure patterns were compared for children 18 years of age or younger for whom a claim with a diagnosis of SCA was submitted and paid in the State of Washington during fiscal year 1993 (FY1993) or by the FEP during FY1992 to expenditure patterns for all children. RESULTS: Children with SCA had mean expenditures 8.8 times the mean expenditures for all children in WSMP. There was wide variation in the annual expenditures among children with SCA; the most expensive 10% of children accounted for 56% of total expenditures. Ninety-seven percent of the expenditures were concentrated in four broad categories: 72% for inpatient care, 11% for outpatient care, 11% for physician payments, and 3% for prescription drugs. Examination of expenditure and utilization patterns for children with sickle cell anemia enrolled in the FEP yielded similar results. CONCLUSIONS: Unless managed care organizations and capitated pediatricians receive payment rates that reflect the higher expected expenditures of caring for these children, access to and quality of care may suffer. Analyses of practice guidelines and utilization patterns suggest that newborn screening, regular access to specialty facilities, and comprehensive education programs are critical areas that are vulnerable to reductions under capitation.

DRGs and specialized nutrition support. Prospective payment and nutritional support: the need for reform.

The Medicare Prospective Payment System does not recognize the use of parenteral and enteral nutrition services as an explicit factor to be used in determination of DRG payment rates. When the DRGs were originally created, the use of parenteral and enteral nutrition services (PENS) was not coded in discharge data sets. As a result, it was impossible to determine whether patients who received PENS were more expensive to treat. Data we have collected indicate that patients who receive PENS tend to have high hospital costs--costs that often exceed the DRG payments established by the Health Care Financing Administration (HCFA). The potential for a hospital to incur a financial loss as a result of treating patients who require PENS could make such patients less attractive to hospitals and thus could adversely affect patients requiring these services. In order to minimize this possibility, we suggest several alternative modifications to the DRG payment system. The modifications would provide higher payments for patients who require PENS, thereby reducing the possibility of discrimination against these patients. By readjusting the DRG prices for patients who do not require PENS, the entire payment modification can be made budget-neutral.

Comparison of risk adjusters for medicaid-enrolled children with and without chronic health conditions.

OBJECTIVE: Several capitation payment systems have been developed and implemented recently by public and private insurers as well as by individual managed care organizations. Many pediatricians have expressed concern that methods for establishing capitation rates may not adequately account for the higher expected expenditures for children with chronic health conditions. In this study, we evaluate a demographic- and 4 diagnosis-based models, paying particular attention to their performance for children with chronic health conditions. METHODS: We selected children 18 years of age and under who were enrolled in the Maryland Medicaid Program in 1995 and 1996. We defined the population of children with chronic health conditions using ICD-9 codes. Individual and group-level analyses were utilized to measure the ability of the different risk adjustment models to predict expenditures in 1996 based upon information available in 1995. RESULTS: All 4 diagnosis-based models significantly outperformed the demographic model for children overall and for children with chronic health conditions. Differences between diagnosis-based models were small, especially as the size of test populations increased. CONCLUSIONS: Risk adjustment methods that account directly for health status promise to reduce incentives to exclude children with chronic illnesses from managed care plans and to provide a foundation for more appropriate payments to pediatricians who care for these children.

In search of value: an international comparison of cost, access, and outcomes.

The United States spent the most resources on health care of all the twenty-nine industrialized countries in 1996 by a wide margin. Managed care and other recent initiatives have been credited with slowing the rate of increase in the U.S. health care spending in recent years. Although the rate of increase slowed, it was still more rapid than the rate in most other industrialized countries between 1990 and 1996. Among the twenty-nine industrialized countries, the United states had the lowest percentage of its population eligible for publicly mandated insurance in 1995. Since 1960 Greece, Korea, and Mexico have surpassed the United States on this measure. AMong the twenty-nine industrialized countries, only the United States had less than half of its population eligible for publicly mandated health insurance in 1995. The United States appears to be comparable to the other G7 countries in terms of access to physicians, in-patient hospital services, and pharmaceuticals. However, on outcomes indicators such as life expectancy and infant mortality, the United States is frequently in the bottom quartile among the twenty-nine industrialized countries, and its relative ranking has been declining since 1960.

Health spending, access, and outcomes: trends in industrialized countries.

In 1997 the United States spent $3,925 per capita on health or 13.5 percent of gross domestic product (GDP), while the median Organization for Economic Cooperation and Development (OECD) country spent $1,728 or 7.5 percent. From 1990 to 1997 U.S. health spending per capita increased 4.3 percent per year, compared with the OECD median of 3.8 percent. The United States has the lowest percentage of the population with government-assured health insurance. It also has the fewest hospital days per capita, the highest hospital expenditures per day, and substantially higher physician incomes than the other OECD countries. On the available outcome measures, the United States is generally in the bottom half, and its relative ranking has been declining since 1960.

Population aging: a comparison among industrialized countries.

Increasing longevity and declining fertility rates are shifting the age distribution of populations in industrialized countries toward older age groups. Some countries will experience this demographic shift before others will. In this DataWatch we compare the effects of population aging on health spending, retirement policies, use of long-term care services, workforce composition, and income across eight countries: Australia, Canada, France, Germany, Japan, New Zealand, the United Kingdom, and the United States. International comparisons suggest that the United States is generally well positioned to cope with population aging; however, three areas should be carefully monitored: heavy reliance on private-sector funding of retirement, coverage of pharmaceuticals for the elderly, and a high proportion of private long-term care financing.

State regulation of managed care: the impact on children.

As more and more children enroll in managed care, states have responded to concerns expressed by their constituents by passing legislation and developing credentialing requirements to assist families with children in receiving appropriate care from managed care plans. Although most of the legislation and credentialing requirements apply to the population generally, a few provisions apply specifically to children. The legislation and credentialing requirements attempt to improve both access to medical care and the quality of care by enacting access-to-care and quality-of-care provisions, reducing the financial incentives for providers to offer inappropriate care, and providing families with more information about their choices and opportunities to redress their grievances. Although there is no empirical evidence, analysis of similar types of legislation suggests that certain approaches will be more successful than others; one obvious indicator of success is the ability of the regulatory agency to develop clear, unambiguous, enforceable rules. Existing legislation varies widely across states in terms of the issues addressed and the specificity of the laws. For the most part, this legislation has been piecemeal, addressing specific issues as they arise. In the long run, state legislatures may not have the time or the expertise to regulate the managed care industry, and other regulatory bodies may be better equipped to address concerns about managed care. If utilized, however, existing regulatory bodies, which historically monitored fee-for-service medicine, will need to be redesigned to monitor managed care.
