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

"This analysis considers some aspects of the international migration of Mexican women, seen under the light of two recent statistical sources: the [U.S.] 1990 census and the 1993-1994... International Migration Survey at the Mexican Northern Border. The joint analysis of migrations and migrant inventories reveals the hidden scope of feminine exile, as well as some of its peculiarities, and offers numerical answers to two questions: How does sex differentiate Mexican immigrants in the United States? How does the migration affect work, marriage, child-bearing, etc. of Mexican women? The results suggest the need to address migration no longer as an action of individuals, but of families (most immigrants are married), and to place the mother or the wife at the gravity center of the household migratory space."
