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

Nikrowa is a riverine village located in Ovia North-East Local Government Area of Edo State. This paper examines the relationship between the environment and the health status of women and children in the village. Data used in this essay were obtained mainly in focus groups from a study of women and health service utilization in Nikrowa. Women in Nikrowa farm, fish, collect water and firewood, and process and prepare food. They also bear many children. Their hard physical labor causes them to suffer continuous body aches and pains. Environment-related illnesses such as malaria, measles, dysentery, and diarrhea are prevalent among children. The geographical isolation of Nikrowa limits access to modern health care facilities, so traditional therapies are used to treat prevailing illnesses. It is suggested that women have access to fertilizers in order to improve soil fertility and agricultural yields. Fuelwood and adequate and safe water supplies should be made readily available to women. Moreover, access roads to rural areas should be improved to facilitate transport to modern health care facilities, and rural primary health care facilities should be helped to provide efficient services by providing trained staff and ensuring regular supplies of drugs. 相似文献

The conventional wisdom strongly suggests a health care provider food chain for the future: Primary care physicians (PCPs), principally family practitioners, on the top playing the lead role, distantly followed by specialists, with hospitals and other ancillary services even further down the line. Is this a reasonable expectation? Will PCPs dominate the new systems? Or will they be but one of many equally necessary components of these developing integrated health care delivery organizations? Looking at the various models now developing, it would seem that future integrated delivery systems will utilize both PCPs and specialists, but with strong augmentation from a diverse assortment of other health care professionals, including nonphysician providers, educators, and administrators. To separate the illusion of primary care dominance of the coming health care system from the likely reality, we should first determine what is driving the apparent present demand for primary care physicians. Next, we will examine the possible and probable reactions to that demand from an economic standpoint and from the points of view of both health care professionals and the public. Finally, we must try to picture how health care provider organizations of the future are likely to look and how they will integrate their health care professionals. 相似文献

Thompson RE 《Physician executive》1995,21(11):9-11
When the author gazed into the proverbial mirror and asked if the U.S. health care system was the fairest of them all, it shattered. In this article, Thompson tells why the system is broken and what failure to fix it means to physician executives. He suggests that we, as Americans, must reinvent ourselves by realigning our value systems and and stifling our obsession with profit before trying to reinvent health care. 相似文献

Suppose that social welfare function f satisfies the Pareto condition and has complete and transitive values. On a domain satisfying the free quadruple property, if the outcome set X has m< outcomes, then the set of pairs of distinct alternatives on which f satisfies both independence and nondictatorship contains at most the fraction 2/m of all pairs. On a domain satisfying the free six-tuple property, if X is a subset of Euclidean space then the set of pairs on which f satisfies both independence and nondictatorship has Lebesgue measure zero.Campbell's research was financed by the National Science Foundation, grant SES 9209039. 相似文献
