(1/4142) Selecting subjects for participation in clinical research: one sphere of justice.
Recent guidelines from the US National Institutes of Health (NIH) mandate the inclusion of adequate numbers of women in clinical trials. Ought such standards to apply internationally? Walzer's theory of justice is brought to bear on the problem, the first use of the theory in research ethics, and it argues for broad application of the principle of adequate representation. A number of practical conclusions for research ethics committees (RECs) are outlined. Eligibility criteria in clinical trials ought to be justified by trial designers. Research ethics committees ought to question criteria that seem to exclude unnecessarily women from research participation. The issue of adequate representation should be construed broadly, so as to include consideration of the representation of the elderly, persons with HIV, mental illness and substance abuse disorders in clinical research.

(2/4142) Views of managed care--a survey of students, residents, faculty, and deans at medical schools in the United States.
BACKGROUND AND METHODS: Views of managed care among academic physicians and medical students in the United States are not well known. In 1997, we conducted a telephone survey of a national sample of medical students (506 respondents), residents (494), faculty members (728), department chairs (186), directors of residency training in internal medicine and pediatrics (143), and deans (105) at U.S. medical schools to determine their experiences in and perspectives on managed care. The overall rate of response was 80.1 percent. RESULTS: Respondents rated their attitudes toward managed care on a 0-to-10 scale, with 0 defined as "as negative as possible" and 10 as "as positive as possible." The expressed attitudes toward managed care were negative, ranging from a low mean (+/-SD) score of 3.9+/-1.7 for residents to a high of 5.0+/-1.3 for deans. When asked about specific aspects of care, fee-for-service medicine was rated better than managed care in terms of access (by 80.2 percent of respondents), minimizing ethical conflicts (74.8 percent), and the quality of the doctor-patient relationship (70.6 percent). With respect to the continuity of care, 52.0 percent of respondents preferred fee-for-service medicine, and 29.3 percent preferred managed care. For care at the end of life, 49.1 percent preferred fee-for-service medicine, and 20.5 percent preferred managed care. With respect to care for patients with chronic illness, 41.8 percent preferred fee-for-service care, and 30.8 percent preferred managed care. Faculty members, residency-training directors, and department chairs responded that managed care had reduced the time they had available for research (63.1 percent agreed) and teaching (58.9 percent) and had reduced their income (55.8 percent). Overall, 46.6 percent of faculty members, 26.7 percent of residency-training directors, and 42.7 percent of department chairs reported that the message they delivered to students about managed care was negative. CONCLUSIONS: Negative views of managed care are widespread among medical students, residents, faculty members, and medical school deans. (+info)
(3/4142) The relation between funding by the National Institutes of Health and the burden of disease.
BACKGROUND: The Institute of Medicine has proposed that the amount of disease-specific research funding provided by the National Institutes of Health (NIH) be systematically and consistently compared with the burden of disease for society. METHODS: We performed a cross-sectional study comparing estimates of disease-specific funding in 1996 with data on six measures of the burden of disease. The measures were total mortality, years of life lost, and number of hospital days in 1994 and incidence, prevalence, and disability-adjusted life-years (one disability-adjusted life-year is defined as the loss of one year of healthy life to disease) in 1990. With the use of these measures as explanatory variables in a regression analysis, predicted funding was calculated and compared with actual funding. RESULTS: There was no relation between the amount of NIH funding and the incidence, prevalence, or number of hospital days attributed to each condition or disease (P=0.82, P=0.23, and P=0.21, respectively). The numbers of deaths (r=0.40, P=0.03) and years of life lost (r=0.42, P=0.02) were weakly associated with funding, whereas the number of disability-adjusted life-years was strongly predictive of funding (r=0.62, P<0.001). When the latter three measures were used to predict expected funding, the conclusions about the appropriateness of funding for some diseases varied according to the measure used. However, the acquired immunodeficiency syndrome, breast cancer, diabetes mellitus, and dementia all received relatively generous funding, regardless of which measure was used as the basis for calculating support. Research on chronic obstructive pulmonary disease, perinatal conditions, and peptic ulcer was relatively underfunded. CONCLUSIONS: The amount of NIH funding for research on a disease is associated with the burden of the disease; however, different measures of the burden of disease may yield different conclusions about the appropriateness of disease-specific funding levels.

(4/4142) Research, ethics and conflicts of interest.
In this paper, I have tried to develop a critique of committee procedures and conflict of interest within research advisory committees and ethical review committees (ERCs). There are specific features of conflict of interest in medical research. Scientists, communities and the subjects of research all have legitimate stakeholdings. The interests of medical scientists are particularly complex, since they are justified by the moral and physical welfare of their research subjects, while the reputations and incomes of scientists depend on the success of their science. Tensions of this kind must at times produce conflict of interest. It is important to recognise that conflicts of interest may unwittingly lead to manipulation of research subjects and their lay representatives on research committees. It is equally important to recognise distinctions between the legal and moral aspects of conflict of interest. Some practical suggestions are made which may go some way towards resolving these difficulties. They indicate what might be needed to ensure the validity of ethical discourse, and to reduce the risks associated with conflict of interest. (+info)
(5/4142) Fraud, misconduct or normal science in medical research--an empirical study of demarcation.
OBJECTIVES: To study and describe how a group of senior researchers and a group of postgraduate students perceived the so-called "grey zone" between normal scientific practice and obvious misconduct. DESIGN: A questionnaire concerning various practices including dishonesty and obvious misconduct. The answers were obtained by means of a visual analogue scale (VAS). The central (two quarters) of the VAS were designated as a grey zone. SETTING: A Swedish medical faculty. SURVEY SAMPLE: 30 senior researchers and 30 postgraduate students. RESULTS: Twenty of the senior researchers and 25 of the postgraduate students answered the questionnaire. In five cases out of 14 the senior researchers' median was found to be clearly within the interval of the grey zone, compared with three cases for the postgraduate students. Three examples of experienced misconduct were provided. Compared with postgraduate students, established researchers do not call for more research ethical guidelines and restrictions. CONCLUSION: Although the results indicate that consensus exists regarding certain obvious types of misconduct the response pattern also indicates that there is no general consensus on several procedures.

(6/4142) Coverage by the news media of the benefits and risks of medications.
BACKGROUND: The news media are an important source of information about new medical treatments, but there is concern that some coverage may be inaccurate and overly enthusiastic. METHODS: We studied coverage by U.S. news media of the benefits and risks of three medications that are used to prevent major diseases. The medications were pravastatin, a cholesterol-lowering drug for the prevention of cardiovascular disease; alendronate, a bisphosphonate for the treatment and prevention of osteoporosis; and aspirin, which is used for the prevention of cardiovascular disease. We analyzed a systematic probability sample of 180 newspaper articles (60 for each drug) and 27 television reports that appeared between 1994 and 1998. RESULTS: Of the 207 stories, 83 (40 percent) did not report benefits quantitatively. Of the 124 that did, 103 (83 percent) reported relative benefits only, 3 (2 percent) absolute benefits only, and 18 (15 percent) both absolute and relative benefits. Of the 207 stories, 98 (47 percent) mentioned potential harm to patients, and only 63 (30 percent) mentioned costs. Of the 170 stories citing an expert or a scientific study, 85 (50 percent) cited at least one expert or study with a financial tie to a manufacturer of the drug that had been disclosed in the scientific literature. These ties were disclosed in only 33 (39 percent) of the 85 stories. CONCLUSIONS: News-media stories about medications may include inadequate or incomplete information about the benefits, risks, and costs of the drugs as well as the financial ties between study groups or experts and pharmaceutical manufacturers.

(7/4142) A national survey of policies on disclosure of conflicts of interest in biomedical research.
BACKGROUND: Conflicts of interest pose a threat to the integrity of scientific research. The current regulations of the U.S. Public Health Service and the National Science Foundation require that medical schools and other research institutions report the existence of conflicts of interest to the funding agency but allow the institutions to manage conflicts internally. The regulations do not specify how to do so. METHODS: We surveyed all medical schools (127) and other research institutions (170) that received more than $5 million in total grants annually from the National Institutes of Health or the National Science Foundation; 48 journals in basic science and clinical medicine; and 17 federal agencies in order to analyze their policies on conflicts of interest. RESULTS: Of the 297 institutions, 250 (84 percent) responded by March 2000, as did 47 of the 48 journals and 16 of the 17 federal agencies. Fifteen of the 250 institutions (6 percent)--5 medical schools and 10 other research institutions--reported that they had no policy on conflicts of interest. Among the institutions that had policies, there was marked variation in the definition and management of conflicts. Ninety-one percent had policies that adhered to the federal threshold for disclosure ($10,000 in annual income or equity in a relevant company or 5 percent ownership), and 9 percent had policies that exceeded the federal guidelines. Only 8 percent had policies requiring disclosure to funding agencies, only 7 percent had such policies regarding journals, and only 1 percent had policies requiring the disclosure of information to the relevant institutional review boards or to research subjects. Twenty journals (43 percent) reported that they had policies requiring disclosure of conflicts of interest. Only four federal agencies had policies that explicitly addressed conflicts of interest in extramural research, and all but one of the agencies relied primarily on institutional discretion. CONCLUSIONS: There is substantial variation among policies on conflicts of interest at medical schools and other research institutions. This variation, combined with the fact that many scientific journals and funding agencies do not require disclosure of conflicts of interest, suggests that the current standards may not be adequate to maintain a high level of scientific integrity.

(8/4142) Publication ethics and the research assessment exercise: reflections on the troubled question of authorship.
The research assessment exercise (RAE) forms the basis for determining the funding of higher education institutions in the UK. Monies are distributed according to a range of performance criteria, the most important of which is "research outputs". Problems to do with publication misconduct, and in particular, issues of justice in attributing authorship, are endemic within the research community. It is here argued that the research assessment exercise currently makes no explicit attempt to address these concerns, and indeed, by focusing attention on research outputs, may actually be fostering such ethical problems.
