The ethics of managed care: a dose of realism

This article examines the ethics of medical practice under managed care from a pragmatic perspective that gives physicians more useful guidance than existing ethical statements. The article begins by stating the authors' starting premises and framework for constructing a realistic set of ethical principles: namely, that bedside rationing in some form is permissible; that medical ethics derive from physicians' role as healers; that actual agreements usually trump hypothetical ones; that ethical statements are primarily aspirational, not regulatory; and that preserving patient trust is the primary objective. The authors then articulate the following concrete ethical guides: financial incentives should influence physicians to maximize the health of the group of patients under their care; physicians should not enter into incentive arrangements that they would be embarrassed to describe accurately to their patients or that are not in common use in the market; physicians should treat each patient impartially, without regard to source of payment, and in a manner consistent with the physician's own treatment style; if physicians depart from this ideal, they must tell their patients honestly; and it is desirable, although not mandatory, to differentiate medical treatment recommendations from insurance coverage decisions by clearly assigning authority over these different roles and by having physicians to advocate for recommended treatment that is not covered.     

The use of expensive health technologies in the era of managed care: the remarkable case of neonatal intensive care

The use of neonatal intensive care (NIC) continued to rise rapidly in the 1990s despite the concerns of observers about its cost effectiveness and its successes being mostly in facilities with high volume and capabilities. The objective of this study is to test the effects of insurance type, competition among hospitals, and market pressure from managed care plans on the supply and cost of NIC. The analysis uses logistic and linear models with techniques to avoid bias from (a) market area definitions based on actual patient flows and (b) self-selection of hospitals by patients with unmeasured risk of needing NIC. The data source contains all births in short-term hospitals in New Jersey during 1990 and 1994. Both the number of days and charges for NIC are reported. Key findings are that the decision of a hospital to offer NIC was associated with teaching status, the proportion of infants in the market area with documented high risk, and the market concentration of major competitors. The market share of managed care plans and the concentration of enrollment were not associated with either NIC being offered or with the standardized charges. Whether a particular patient was given to a NIC depended on patient risk factors and whether a NIC unit was present, but not on payer group. The results are consistent with the hypothesis that young insured parents (with the advice of their obstetricians) prefer hospitals with NIC and also are relatively profitable enrollees for health plans. In conclusion: using the results here and in other research, public and private policy makers may consider several ways to strengthen the incentives for health plans to contract for cost-effective birth-related services. The results also raise questions for a number of regulatory and payment policies and call for better public data on costs and outcomes for NIC.     

State Medicaid managed care enrollment: understanding the political calculus that drives Medicaid managed care reforms

The objective of this article is to understand the political motivations underlying Medicaid managed care reforms by examining the determinants of enrollment of beneficiaries in managed care plans in the fifty states. To highlight the role of the model variables, including measures of the political environment, public interest, and special interests, a distinction is made between capitated and fee-for-service managed care enrollment. The results show that cost containment within the context of the Medicaid program is perceived as strongly favored by voters. Accordingly, the relative cost and tax price of providing Medicaid services are important factors in states' decision to enroll Medicaid beneficiaries in managed care plans, particularly capitated ones. The results also indicate a surprisingly significant influence by labor unions that generally oppose managed care enrollment for fears of lost jobs. The recipient population and provider groups also play an important role in shaping the Medicaid managed care landscape. The influence of variables measuring states' ability and willingness to pay and median voter preferences suggest that, within the context of Medicaid managed care enrollment, the public's interests are being served; however, the results also point toward inequities within the program and implications concerning financing arrangements between states and the federal government.     

Effects of Tennessee Medicaid managed care on obstetrical care and birth outcomes

A comparative study was conducted in two neighboring states, Tennessee and North Carolina, to determine whether Medicaid managed care (implemented in Tennessee as TennCare) affected prenatal care, care patterns at labor-delivery, and birth outcomes. A pre- and post-design coupled with a difference-in-difference approach--using North Carolina as a control--was used to assess TennCare's effects for all births and for three categories of high-risk mothers (under age eighteen, unwed, or living in high poverty areas). Data from 328,296 singleton births in birth files and matched birth-death files for 1993 and 1995 in both states were used to analyze a number of variables related to maternal behavior during pregnancy, utilization of care before and after labor-delivery, patterns of obstetrical care at delivery, and birth outcomes. Under TennCare, Tennessee mothers were relatively more likely to obtain no prenatal care or to wait and initiate third trimester care as compared to those in North Carolina. Relative utilization of specific prenatal procedures declined, Apgar scores fell very slightly, and birth abnormalities increased in the poverty subsample. TennCare had no significant effect on infant mortality. Utilization reductions in obstetrical services were achieved with apparent spillovers to non-TennCare births, but without adverse effects overall. TennCare was neither a panacea nor an unmitigated disaster. It is a model worth examining, but not uncritically.
