This report assesses the effects on peripheral oxygen saturation and heart rate that positional restraint induces when a person is prone, handcuffed, and "hog-tied." Peripheral oxygen saturation and heart rate were monitored at rest, during exercise, and during recovery from exercise for 10 adult subjects. The effects of positional restraint produced a mean recovery time that was significantly prolonged. Consequently, the physiological effects produced by positional restraint should be recognized in deaths where such measures are used.  相似文献

This paper compares the Medicare prospective payment system (PPS) to four all-payer rate-setting systems that operated under HCFA waiver authority. The study examines the experience of Medicare, Medicaid, and commercial insurers under the two approaches. Data from several American Hospital Association surveys and from Medicaid 2082 report forms are analyzed. The paper concludes that the all-payer waiver programs have been as successful as PPS in controlling the rate of growth in Medicare costs. In addition, Medicaid programs are more successful in controlling their outlays in all-payer rate-setting environments than when they "go alone." Finally, there is no evidence to suggest that hospitals can increase charges in response to greater financial need under either PPS or the state waivers. Nevertheless, it appears that commercial insurers are better able to compete with Blue Cross plans in all-payer rate-setting states than elsewhere.  相似文献

Assessment of competency for execution presents two compelling ethical questions for mental health professionals: whether clinicians can ethically provide such assessment, and if so, how it should be done in order to maximize quality and minimize ethical conflict. In this article we address the issue of whether to participate and, if so, how. The question of whether to participate is discussed by summarizing the arguments for and against participation and offering guidelines for making a decision. The question of how to proceed is discussed in two contexts: preadjudication (before a formal decision about competency) and postadjudication (following a determination of "incompetent" and transfer of the offender to another facility for treatment and further assessment). Finally, recommendations are made regarding research that would improve the quality of execution competency assessments.  相似文献

Rapidly escalating health-care inflation and congressionallymandated expansions have led to large increases in spendingfor Medicaid, the federal-state program of health care for thepoor. These increases came at a time when state budgets werealready under recession-induced stresses. In addition, 1991brought new pressures for Medicaid spending from the courtsand closer federal scrutiny and control over revenues used forthe program's state "match." Yet the Medicaid picture is farfrom bleak. Diversity, innovation, and an emerging stale policyrole also characterize the program in ways that epitomize thestrengths and weaknesses of the American intergovernmental system.  相似文献
