Renal function after nephrectomy for Wilms'' tumor]

In times of reduced monetary resources of the current German health system, it is more and more difficult for the German physicians to comply with the high medicinal care standard and to practice economically. Nevertheless, the economical reasons cannot deny the high medical quality standards. Regarding the principle of the unity of jurisdiction, the validity of the social welfare law, that a performance has to be "just sufficient and suitable", must concur with the demand of liability law of "indication of the medical service". The economical duties reach their limit when they increase the risk for the patient. On the other hand, the economy interests have to be regarded by the "principle of the allowed risk". Therefore, it should be considered that in every single case the severity and probability of the risk has to be weighed against the cost aspect.     

Postoperative nausea and vomiting. A retrospective analysis in patients undergoing elective craniotomy

CONTEXT: Managed care and capitation have placed new responsibilities on primary care physicians, including formally acting as "gatekeepers" for specialty services and tests. Previous studies have not examined whether primary care physicians who provide services to patients under many coverage arrangements feel differently about caring for patients covered under capitation vs those covered through more traditional forms of insurance. An understanding of whether California primary care physicians feel that they deliver a different level of quality to capitated patients could help signal whether variations in care for patients with different coverage forms are evolving. OBJECTIVE: To evaluate whether primary care physicians in California capitated groups report different satisfaction levels with quality of care for patients in their overall practice than for patients covered by capitated contracts and to examine whether physicians' satisfaction with capitated care quality is influenced by the characteristics of the practice setting. DESIGN: Cross-sectional questionnaire. SETTING: A total of 89 California physician groups with capitated contracts. PARTICIPANTS: A total of 910 primary care physicians (80% response rate). MAIN OUTCOME MEASURE: Satisfaction with 4 aspects of quality of care provided to patients covered by capitated contracts vs patients overall. RESULTS: Physicians reported lower satisfaction with all 4 aspects of care for patients covered by capitated contracts than for patients in their overall practice: 71% were very or somewhat satisfied with relationships with capitated patients (compared with 88% for overall practice), 64% were very or somewhat satisfied with the quality of care they provided to capitated patients (compared with 88% for overall practice), 51% were very or somewhat satisfied with their ability to treat capitated patients according to their own best judgment (compared with 79% for overall practice), and 50% were very or somewhat satisfied with their ability to obtain specialty referrals (compared with 59% for overall practice) (P< or =.001 for all comparisons). Being in a medical group practice (vs an independent practice association) and having a larger percentage of capitated patients were independently associated by multivariate analysis with higher levels of satisfaction with capitated quality of care (P< or =.005). CONCLUSION: These California primary care physicians were less satisfied with the quality of care they deliver to patients covered by capitated contracts than with the quality of care they deliver to patients covered by other payment sources. However, those in medical group practices and with a higher percentage of capitated patients were more satisfied with capitated care. National expansion of capitation should be accompanied by efforts to ensure that the satisfaction of practicing physicians with the care they deliver does not decline.     

Evidence-based medicine. How to use biomedical literature to solve clinical problems. Italian Group on Evidence-Based Medicine-GIMBE

Clinical practice is constantly changing, the rate of changing is accelerating and consequently it may even take years before the results of clinical research will be incorporated in day-to-day practice. So, there is a large gap between what the biomedical literature contains and the care that most of patients receive. The gap is widened by the extensive processing that results of clinical research require before they can be used. Evidence-based medicine is a new approach to health care promoting the collection, interpretation, and integration of valid, important and applicable research-derived evidence. The best available evidence, moderated by patient circumstances and preferences, is applied to improve the quality of clinical judgements. There are many information tools that facilitate the practice of evidence-based medicine. These include users' guides to the medical literature, strategies to improve the yield of MEDLINE searches, standardized formats for abstracts of journal articles and guidelines, new journals, systematic reviews and meta-analyses, resources on-line and software tools bringing high quality information to the point of clinical decision making. However, these tools are poorly spread and physicians lack of necessary skills for their effective utilization. In this article the authors describe guidelines for efficient and effective utilization of biomedical information tools to solve clinical problems and improve the quality and the cost/effectiveness of health care.     

Medical liability in the treatment of intensive care unit patients

Critical care medicine was practiced informally during several years, specially during war periods. Nowadays it is, however, a fundamental part of health systems in which patients attain care facilities of increasing complexity in a cost effective manner, according to their needs. The importance of this discipline in Chile, during its 30 years of development, has progressively increased and at the present time, intensive care units represent up to 30% of the total number of beds in some hospitals. Even though these units require great budgets and many resources, their place and the role of physicians who work in them has not been recognized adequately by the national medical community. The present document presents the official position of the Chilean Society of Intensive Medicine on the general objectives of this discipline. It indicates the scope of action of the specialty and the role of intensive care physicians, their relationship with other specialties, their duties and responsibilities with their patients.     

Biomedical ethics and the biomedical engineer: a review

Biomedical engineering is responsible for many of the dramatic advances in modern medicine. This has resulted in improved medical care and better quality of life for patients. However, biomedical technology has also contributed to new ethical dilemmas and has challenged some of our moral values. Bioengineers often lack adequate training in facing these moral and ethical problems. These include conflicts of interest, allocation of scarce resources, research misconduct, animal experimentation, and clinical trials for new medical devices. This paper is a compilation of our previous published papers on these topics, and it summarizes many complex ethical issues that a bioengineer may face during his or her research career or professional practice. The need for ethics training in the education of a bioengineering student is emphasized. We also advocate the adoption of a code of ethics for bioengineers.     

Quality and outcomes management in gastroenterology

The delivery of medical care is undeniably changing. Resources are becoming increasingly scarce, and the progressive rise of health care expenditures needs to be restrained. Although the field of outcomes assessment is not well understood, it is increasingly being applied to the practice of medicine. The underlying goal of outcomes management should be to improve quality by identifying the most efficient use of finite resources and integrating these into practice guidelines. Although reduction of health care costs is important, it should be a secondary goal. Providers of health care must take an active role in outcomes research and management both in understanding and in implementing these techniques in medical practice. In doing so, it is essential that physicians maintain the proper emphasis on quality patient care.     

Viability and recovery of peripheral blood mononuclear cells cryopreserved for up to 12 years in a multicenter study

Polish physicians-philosophers tried to find a compromise between medicine as a science and medicine as a healing art. They stated that clinical practice should be transformed into science, bearing in mind that there would be no medicine without the existence of the sick. A perfect physician is a good and wise person and not exclusively a proficient expert. Polish physicians exercised a science that they called philosophy of medicine. It included logic, psychology, and medical ethics. The Polish school claimed that the history of medicine and philosophy of medicine are necessary for future doctors. The historical and philosophical approach makes it possible to recognize the subject of medicine (health, disease, and the sick) and its aim (treatment, restoration of health or just alleviation of suffering). The ethics teaches what values are pursued by medicine, what moral duties a doctor has, and what role model to follow to become a good physician. Placing the sick in the focus of medical interest, the Polish school taught future physicians to see in them suffering fellow men who should be embraced with care, compassion, and Christian charity. Such an approach to the ethical aspect of medical philosophy became incorporated into an education towards humane values, responsibility for ones' life and health in the spirit of the ethics of care.     

Ethical care at the end of life

In treating dying patients, who by virtue of their physical and emotional situation are frail and vulnerable, physicians must meet a high standard of professional, ethical care. Such a standard is based upon a philosophy of care that recognizes the patients' inherent worth as human beings and their uniqueness as individuals. The ethical and virtuous physician will practice in accordance with the principles of biomedical ethics that form the foundations of thought and treatment approaches in this area and will seek to do the best for the patient and the family. "Doing the best" includes respecting autonomy through gentle truth-telling, helping the patient and family to set treatment goals, and providing for symptom control, continuing attentive care and accompaniment throughout the course of the illness. Total care includes physical, emotional and spiritual aspects, is sensitive to cultural values and is best provided by an interdisciplinary team. Practices of symptom control in routine care and in crisis situations, as well as the cessation and non-initiation of treatment, will have as their goals the relief and comfort of the patient. The ethical physician will not act with the intention of bringing about the death of the patient, whether by ordering medication in excess of that required for symptom control, administering a lethal injection or any other means.     

U. S. medical graduates versus foreign medical graduates. Are there performance differences in practice?

This study has attempted to determine the relationship between physicians' medical education and their performances (technical quality and utilization of medical care resources) in offices and hospitals. The sample consisted of 506 physicians of Hawaii, involving 18 specialty categories. The study finds little evidence of the influence of the type of medical schools on physicians' technical quality and utilization of medical resources in practice. The mean differences between the categories of medical schools were not statistically significant (except for the quality when specialists practiced within their own areas of specialization). There is no evidence that all categories of U.S. medical graduates provided a higher quality care and better utilization than all categories of foreign medical graduates. There was no consistent pattern of performances within the categories of U.S. medical schools and of foreign medical schools in these dimensions of performances.     

Applying Hamlet's question to the ethical conduct of research: A conceptual addendum.

Contends that decision models used to ensure cost–utility guidelines in research are insufficient because they fail to consider the cost–utility of not conducting a particular study. It is suggested that those who argue that a given study is unethical and should be prohibited should be prepared to answer in ethical and moral terms for the consequences of their decision. It is concluded that ethical responsibilities include protection of the integrity of work to insure that it measures up to the standards of good scientific practice and respect for the dignity of persons and values studied in the pursuit of scientific knowledge.

Review of the regulations on quality control of human albumin

PURPOSE: To assess medical students' perceptions of the ethical environment across four years of medical school. METHOD: In the spring of 1996, the authors distributed a questionnaire to all four classes at the Wake Forest University School of Medicine. The students provided demographic information and information about their exposures to or participation in unethical situations. Results were analyzed using multiple analysis of variance, univariate analysis of variance, Pearson correlation, and cross-tabulations. RESULTS: The response rate was 71%. The students reported that exposures to unethical behavior started early and continued to increase with each year in school. For example, 35% of the first-year students reported observing unethical conduct by residents or attending physicians. This percentage rose to 90% of the fourth-year students. The authors found no significant relationship between demographic variables other than the year in school and the ethical dilemma variables. CONCLUSION: Medical students face perceived ethical dilemmas beginning as early as the first year of medical school. Thus ethics instruction must begin in the freshman year. In addition, there must be changes to the environment in which clinical education is conducted to enhance the positive enculturation of students into the medical profession.     

Physicians' view of practice guidelines. A survey of Italian physicians

After more than 10 years of development, two different views of practice guidelines are emerging: either as an educational tool for the medical profession, or as a forum where health care issues can be debated by physicians and non-medical groups. Physicians use practice guidelines in the former model to set their own standards of good quality care, while the latter approach needs contributions from other components in order to decide what should be provided by our health care systems. In a survey of Italian physicians' opinions and attitudes toward practice guidelines, responders supported the "narrowest" model. More than 80% stated that improvement of quality of care and reduction of variation in clinical and practice styles should be the aim of practice guidelines, without representatives from outside the medical profession being involved (61%, 79% and 86% disagreed with a possible involvement, respectively, of patients, health care administrators and representatives of the public at large). Overall, 38% of physicians had a positive attitude toward guidelines viewed as a quality assurance tool for the medical profession. Overall, physicians seem to ignore that the need to rationalize health care calls for input from other professions and members of society. Indeed, most of the issues facing medicine today are mainly a matter of how much value our societies attach to the benefit expected from the available health services. The answers as to what should be done in health care probably cannot be left to the medical profession alone.     

Guidelines as a strategy for preserving professional autonomy

Practice guidelines are often perceived as a threat to physician autonomy. However, the true challenge to physician autonomy is the rising costs of health care, which in turn is the result of continued progress in medical research. Since, inevitably, choices must be made about how our limited resources are expended, an increasing number of physicians are concluding that health care providers should assume financial risk for providing care--so that providers can make the decisions about which interventions are used for which patients. In this context, groups of physicians are adopting practice guidelines as an important strategy for providing high quality and efficient care under capitation. At least in some areas, practice guidelines are emerging as a critical tool for physicians to assume financial risk, and thereby protect professional autonomy.     

Patient values: the guide to medical decision making

Physicians are increasingly challenged by issues surrounding medical decision-making for hospitalized patients. Advance directives express a patient's preferences regarding end-of-life care; when available, they should be used to guide medical treatment. Patients who lack decision-making capacity require special consideration to ensure maximal patient participation with appropriate surrogate involvement. An ethics committee consultation may be especially helpful to resolve conflicts that may arise regarding medical treatments. Physicians play a vital role in promoting earlier patient-physician discussions about end-of-life care preferences, increased completion of advance directives, and ongoing education for physicians to improve communication skills.     

Oxidative damage to the eye lens caused by cigarette smoke and fuel smoke condensates

The degree to which a reformed U.S. health care system relies on an adequate supply of primary care physicians will determine the urgency of change in the composition of the medical workforce. In many areas of the United States, the demand for primary care physicians, particularly in managed care settings, far exceeds the supply. In contrast, reports of reduced practice opportunities for medical and surgical subspecialists in the same settings are increasing. As opportunities for and incomes of primary care physicians are enhanced, some medical subspecialists may seek retraining in primary care. This article provides a context for understanding the development of physician retraining programs, examines precedents for retraining physicians, describes four possible pathways through which medical subspecialists might acquire primary care training, and emphasizes the importance of defining the scope of practice and necessary skills for providing primary care. Obstacles to retraining appear to be economic (Who will pay? Is the cost worth the benefit?) and jurisdictional (Who will define core competencies? Who will credential programs and trainees?). The current absence of demand for such retraining programs suggests either that marketplace-induced changes will not take place or that the notion of a primary care provider shortage and an oversupply of medical subspecialists is overstated. The inclusion of physician retraining programs in proposed health reform legislation suggests that policymakers are convinced that such programs offer one viable solution to the nation's medical workforce needs.     

Physician's attitudes toward the ill aged and nursing homes

A survey of physicians in private practice (exclusive of pediatricians) was conducted in a medium sized suburban city in the New York metropolitan area, to determine whether physicians' attitudes toward the ill aged and nursing homes were predictors of the quality of medical care available to area nursing home patients. Questionnaires were circulated to 302 practitioners. Of the 28 percent who responded, 32 percent were psychiatrists, 15 percent primary care physicians and 8 percent orthopedists. Physicians felt competent to manage the ill aged, although 50 percent had had no significant degree of exposure to geriatric medicine in their medical education, and 70 percent of the primary care group had had none. Primary care and older physicians were more likely to treat patients in nursing homes. Almost 40 percent viewed the nursing home as a place to die. Although 85 percent studied that physicians should be involved in the nursing home displacement process, only 21 percent believed that they continued to be in charge of their patients after placement. The findings demonstrate generalized medical disinterest in the care of ill aged patients in institutions. The persons responsible for awarding government grants and those involved in planning medical school curricula should pay more attention to the needs of the chronically ill aged.     

Ethical conflicts reported by registered nurse/certified diabetes educators: a replication

The purpose of this study was to identify types of ethical conflicts reported by certified diabetes educators who are also registered nurses (RN/CDEs) and to examine their relationship with demographic, educational and practice setting variables. This study is a replication of an earlier pilot study. Ethical conflicts expressed by RN/CDEs in active practice in New York and Pennsylvania were analysed according to four themes. Disagreement with medical practice was by far the most dominant clinical context for the conflicts (61%), as it had been in the pilot study (75%). Participants believed that 32% of the ethical conflicts were resolved. Ethics committees and consultants were very rarely used. Of the relationships between the kinds of conflicts and their resolution, and demographic, educational and practice setting variables of the participants, only kind of position was significantly (P < 0.005) related to practice context of the ethical conflict.     

The measurement of constitutive and facultative skin pigmentation and estimation of sun exposure in Caucasians with basal cell carcinoma and cutaneous malignant melanoma

OBJECTIVES: The purpose of this study was to examine the dimensions of physician work satisfaction across a variety of medical specialties and practice settings. METHODS: A modified version of the Scheckler et al survey instrument was mailed to all physicians in Marion County, Indiana. Forty-two percent (777) of the eligible physicians responded. Exploratory factor analysis and internal consistency measures were used to assess the instrument's validity and reliability. Multivariable linear regression was used to predict global and summary scale scores. RESULTS: Four dimensions of physician work satisfaction were identified: relationships with patients (k = 6, alpha = 0.81), autonomy in clinical decision-making (k = 8, alpha = 0.81), office resources (k = 7, alpha = 0.87), and professional relationships (k = 5, alpha = 0.82). Most (73%) of the physicians were satisfied with their overall practice, and the majority were also satisfied with their income. Significant differences were observed in the sources and magnitude of physician work satisfaction across medical specialty, practice setting, and financial arrangement. Physicians in private practice were most satisfied with their overall practice and office resources, whereas physicians in health maintenance organizations (HMOs) were most satisfied with their autonomy in clinical decision-making. Physicians not working in HMOs but having a large percentage of patients with capitated reimbursement were not enthusiastic about the effect of managed care on their medical practice. Among primary care physicians, family practitioners and general internists were generally less satisfied, and general pediatricians were generally more satisfied with most aspects of their medical practices. CONCLUSIONS: The modified version of the Scheckler et al instrument is a reliable and valid measure of physician work satisfaction. Increases in the market share of managed care have differentially affected the work satisfaction of physicians based on their medical specialty, practice setting, and financial arrangements.     

Effects of the growth of managed care on academic medical centers and graduate medical education

The author offers insights into how the proliferation of competitive health care financing and service delivery systems based on managed care affects the financial support available to academic medical centers (AMCs), especially to their programs in graduate medical education (GME). The paper is based largely on case studies of AMCs conducted by the author in the summer of 1994 in the health care markets of San Diego, California, Minneapolis-St. Paul, Minnesota, and Washington, D.C., complemented by a review of the literature. In sum, the investigator found consensus among all parties that in the current market, managed care plans neither are willing nor feel able to pay much, if any, premium for the services of AMCs, particularly when established, respected alternatives exist, as they typically do for most services in major urban markets. Relatively few short-term adverse effects on AMCs were found from the growth of competitive systems, but AMCs are nevertheless very concerned that managed care will put them at a disadvantage. They are thus seeking ways to position themselves for the future. The AMCs are concerned that at some point, the cost reductions they are making will hinder the fulfillment of their unique traditional mission, since they believe that the costs of their GME programs can be reduced only so far without harming residents' training. Many managed care plans, however, question the AMC mission, taking issue particularly with the training AMCs provide and its relevance to current needs for primary and ambulatory care. The investigators also found considerable support for pooled funding for GME among diverse parties, but no consensus on how this funding should be structured, who should receive it, or what it should support. Potential conflicts were also identified between national, state, and market objectives for provider supply and specialty distribution because these objectives can embody different criteria for assessing the handling and locations of specialists' training. In addition, the findings indicate that it could be unwise to consider AMC policy independent of workforce objectives; doing so could create conflicts about the kinds of physicians who should be trained. The author concludes with a list of approaches to future research that may be constructive.
