Given the complexity of federal Medicaid law and the limitations it imposes on state flexibility, it is likely that states will continue to ask the Secretary to grant waivers under Section 1115 to allow them to pursue new approaches to health care reform. The results of currently operational Section 1115 projects involving statewide managed care systems will be useful in evaluating the Medicaid reform measures currently under discussion in other states and at the federal level. In particular, the ability of the states to control Medicaid and indigent care costs and to utilize federal dollars more efficiently should prove important in evaluating a block grant approach to federal Medicaid funding. Moreover, Section 1115 project results that bear on the sufficiency of various Medicaid capitation rate methodologies will also be of value as more states expand the use of managed care arrangements for their Medicaid populations.  相似文献

Hospitals tempted to operate their own physician incentive plans are reminded that, under OBRA 1986, they are precluded from paying physician incentives of any kind to reduce or limit Medicare or Medicaid covered services. In light of the proposed regulations and the guidance of the preamble, hospitals should review their incentive plans to determine whether physicians providing direct patient care are receiving prohibited payments. Further, supervising physicians who are receiving incentives for certain hospital departments may not influence direct care over patients served by those departments, even through other physicians. Some risk may also exist if incentives are based on a formula that considers patients of the supervising physician's medical group. Finally, it may be useful to develop a utilization and quality of care review program specifically designed to assure that patient undertreatment does not occur as a result of any supervising physician incentive program.  相似文献

While the regulations are revolutionary in their use of "substantial compliance," the interpretation and application of HCFA's new remedial scheme are still uncertain, as states are given broad discretion in defining important terms and in applying and interpreting the criteria to select remedies. Further complicating the issue is the fact that some states, including California, intend to seek waivers from HCFA to substitute their own state enforcement systems for most, if not all, of the new federal system. Based upon these uncertainties, the enforcement of nursing facility standards will likely be in a state of flux for some time to come.  相似文献

In the West economically motivated crime is usually perceived as a matter for the police while the performance of the economy is a matter for the political authorities. This paper argues that the growth and evolution of the modern underground economy has made such a distinction obsolete. Not only have the frontiers between the legitimate and the criminal sectors of the economy blurred, but the distinction between the explicitly criminal and the merely informal aspects of the modern underground economy has become largely meaningless. Given the tremendous growth of underground activity, this means that the issue must now be addressed not just on the enterprise level, as a police matter, but on the level of the economy as a whole, by economic policy makers. This in fact is something that many developing countries long ago realized. The paper therefore asks whether developing countries have been any more successful in using monetary, fiscal and balance of payments policy to mitigate the adverse social and economic impact of widespread underground economic activity than have Western countries who have relied mainly on the sanction of criminal law. It concludes that both approaches are deficient in so far as they neglect the degree to which modern underground activity can no longer be seen as a manifestation of deviant economic behavior so much as a virtual economic insurgency against the status quo distribution of income and wealth and the codes of economic behavior which accompany it. However dramatic are the financial manifestations of the spread of enterprise crime, ultimately the challenge it poses must be addressed as the political and ideological level.  相似文献
