The following article is one of a series that deal with the provision of health care services around the world. Other countries in the series include Germany, Italy, Japan, Mexico, the Netherlands, and the United States. Countries scheduled for coverage in the series include Austria, France, Singapore, Spain, and the United Kingdom. The countries are described using a grid of characteristics so that comparisons may be made more easily. All of the analyses, along with further comparative data, will be gathered into a freestanding book to be published later in the year. Dr. Mendoza serves as editor for the project.  相似文献

Several countries have attempted to change human fertility through economic incentives. This paper presents simple mathematical models of the participation of couples in a locally funded program of economic incentives. The models take as a springboard China's one-child program. Localities with low per capita incentives attract few couples to the program, while localities with high incentives attract many couples at first, but the value of the benefits is then watered down. The models show that participation in the program may persistently oscillate or may decay to a stationary level. Which behavior occurs is determined by whether there are decreasing, constant, or increasing returns in the rates of participation in response to successive equal increments in the incentive offered, and by the extent to which prospective parents learn from experience with past oscillations in the incentives. The models raise many empirical questions about the dynamics of incentive programs.  相似文献

"This article discusses international migration from Java in the past and present and the role brokers have played in stimulating this movement. It describes legal and clandestine labor migration to Singapore, Malaysia, and Saudi Arabia, the influence of employment brokers on the process, and the organization of the recruitment networks. The involvement of brokers is crucial but not always beneficial for the migrants. Migrants are dependent on the brokers and risk exploitation. In the case of movement to Saudi Arabia, there is a linkage with religious institutions and the Islamic pilgrimage."  相似文献

The heated national health care reform debate of the summer of 1993 has now simmered down, but pieces of the debate are still percolating along at the state level. Within the past year, numerous states have introduced bills that would mandate insurance coverage for investigational cancer therapies--in particular high-dose chemotherapy and bone marrow transplant for breast cancer. The problem with these initiatives, well-intended though they may be, is that they threaten to spread unproven technologies at a rapid rate and at the same time miss the opportunity to collect data that would prove the safety and effectiveness of the methods. The author explores these issues and suggests how managed care companies can play a more aggressive role in parrying the threat.  相似文献

The Department of Justice has estimated that the government loses $100 billion annually in health care fraud. Consequently, the government's health care fraud enforcement activities with respect to all health care providers and suppliers continue to grow. Last year alone, the government collected more than $8 billion in settlements, fines, and penalties involving health care fraud. Recent settlements with the government have begun to include corporate compliance programs that require continued government oversight of the health care organization as an essential part of the settlement. The first section of this article describes the legal significance of health care companies' having corporate compliance programs. The second section provides a sample list of topics that should be included in any corporate compliance program. Finally, we describe various issues related to the creation and implementation of corporate compliance programs.  相似文献

Complaints of discrimination or harassment in the workplace have become almost commonplace in recent years, increasing in both frequency and variety. In the hospital setting, this trend is manifested in allegations against members of the medical staff by hospital employees as well as by patients or their families. Whether real or fancied, such allegations are reflective of a potentially disruptive undercurrent of organizational tensions. Left unresolved, they can erode the essential partnership between staff physicians and other members of the health care delivery team. Unsatisfactory patient experiences may also damage the reputation of the institution and thereby undermine its viability. With either group of complainants, allegations of malfeasance that are not resolved at the source in a timely manner are far more likely to result in expensive, time-consuming, and potentially damaging litigation.  相似文献

Physicians practicing in large, multispecialty medical groups share an organizational culture that differs from that of physicians in small or independent practices. Since 1980, there has been a sharp increase in the size of multispecialty group practice organizations, in part because of increased efficiencies of large group practices. The greater number of physicians and support personnel in a large group practice also requires a relatively more sophisticated management structure. The efficiencies, conveniences, and management structure of a large group practice provide an optimal environment to practice medicine. However, a search of the literature found no data linking a large group practice environment to practice outcomes. The purpose of the study reported in this article was to determine if physicians in large practices have fewer quality and utilization problems than physicians in small or independent practices.  相似文献

"The aim of this paper is, first, to give an overview of the local history approach developed in adult mortality differentials; secondly, to present its potentiality compared with a more usual approach.... Our methodology was applied to Norwegian data."  相似文献
