559After severe brain injury, one of the key challenges for medical doctors is to determine the patient’s prognosis. Who will do well? Who will not do well? Physicians need to know this, and families need to do this too, to address choices regarding the continuation of life supporting therapies. However, current prognostication methods are insufficient to provide a reliable prognosis. Functional Magnetic Resonance Imaging (MRI) holds considerable promise for improving the accuracy of prognosis in …Read more

104Unethical Author AttributionCambridge Quarterly of Healthcare Ethics 12 (1): 124-130. 2003.I am an M.D/Ph.D. student and work as a research assistant for the director of a division of the school of medicine who is an M.D. He assigned me to research a certain topic and gave me no guidelines or guidance as to how to do it. Nevertheless, I did the research and wrote it up. My supervisor liked the report and said that he thought it was so good that “I would like to offer you the opportunity to publish it and list you as the primary author.” Some bells went off when he so grandly offered t…Read more

91Refuting the net risks test: a response to Wendler and Miller's "Assessing research risks systematically"Journal of Medical Ethics 33 (8): 487-490. 2007.Earlier in the pages of this journal (p 481), Wendler and Miller offered the "net risks test" as an alternative approach to the ethical analysis of benefits and harms in research. They have been vocal critics of the dominant view of benefit-harm analysis in research ethics, which encompasses core concepts of duty of care, clinical equipoise and component analysis. They had been challenged to come up with a viable alternative to component analysis which meets five criteria. The alternative must (…Read more

91Why the Debate over Minimal Risk Needs to be ReconsideredJournal of Medicine and Philosophy 39 (4): 387-405. 2014.Minimal risk is a central concept in the ethical analysis of research with children. It is defined as the risks “. . . ordinarily encountered in daily life . . . .” But the question arises: who is the referent for minimal risk? Commentators in the research ethics literature often answer this question by endorsing one of two possible interpretations: the uniform interpretation or the relative interpretation of minimal risk. We argue that describing the debate over minimal risk as a disagreement b…Read more

82The publication of ethically uncertain research: attitudes and practices of journal editorsBMC Medical Ethics 13 (1): 4. 2012.Background: Publication of ethically uncertain research occurs despite well-published guidelines set forth in documents such as the Declaration of Helsinki. Such guidelines exist to aide editorial staff in making decisions regarding ethical acceptability of manuscripts submitted for publication, yet examples of ethically suspect and uncertain publication exist. Our objective was to survey journal editors regarding practices and attitudes surrounding such dilemmas. Methods: The Editor-in-chief of…Read more

80Rehabilitating EquipoiseKennedy Institute of Ethics Journal 13 (2): 93-118. 2003.: When may a physician legitimately offer enrollment in a randomized clinical trial (RCT) to her patient? Two answers to this question have had a profound impact on the research ethics literature. Equipoise, as originated by Charles Fried, which we term Fried's equipoise (FE), stipulates that a physician may offer trial enrollment to her patient only when the physician is genuinely uncertain as to the preferred treatment. Clinical equipoise (CE), originated by Benjamin Freedman, requires that th…Read more

76Ethical Criteria for Human Challenge Studies in Infectious Diseases: Table 1Public Health Ethics 9 (1): 92-103. 2016.Purposeful infection of healthy volunteers with a microbial pathogen seems at odds with acceptable ethical standards, but is an important contemporary research avenue used to study infectious diseases and their treatments. Generally termed ‘controlled human infection studies’, this research is particularly useful for fast tracking the development of candidate vaccines and may provide unique insight into disease pathogenesis otherwise unavailable. However, scarce bioethical literature is currentl…Read more

64Ethics of neuroimaging after serious brain injuryBMC Medical Ethics 15 (1): 41. 2014.Patient outcome after serious brain injury is highly variable. Following a period of coma, some patients recover while others progress into a vegetative state (unresponsive wakefulness syndrome) or minimally conscious state. In both cases, assessment is difficult and misdiagnosis may be as high as 43%. Recent advances in neuroimaging suggest a solution. Both functional magnetic resonance imaging and electroencephalography have been used to detect residual cognitive function in vegetative and min…Read more

63Equipoise and the duty of care in clinical research: A philosophical response to our criticsJournal of Medicine and Philosophy 32 (2). 2007.Franklin G. Miller and colleagues have stimulated renewed interest in research ethics through their work criticizing clinical equipoise. Over three years and some twenty articles, they have also worked to articulate a positive alternative view on norms governing the conduct of clinical research. Shared presuppositions underlie the positive and critical dimensions of Miller and colleagues' work. However, recognizing that constructive contributions to the field ought to enjoy priority, we presentl…Read more

63Placebo Orthodoxy in Clinical Research II: Ethical, Legal, and Regulatory MythsJournal of Law, Medicine and Ethics 24 (3): 252-259. 1996.Placebo-controlled trials are held by many, including regulators at agencies like the United States Food and Drug Administration, to be the gold standard in the assessment of new medical interventions. Yet the use of placebo controls in clinical trials has been the focus of considerable controversy. In this two-part article, we challenge a number of common beliefs concerning the value of placebo controls. Part I critiques statistical and other scientific justifications for the use of placebo con…Read more

61Stakeholder views regarding ethical issues in the design and conduct of pragmatic trials: study protocolBMC Medical Ethics 19 (1): 90. 2018.Randomized controlled trial trial designs exist on an explanatory-pragmatic spectrum, depending on the degree to which a study aims to address a question of efficacy or effectiveness. As conceptualized by Schwartz and Lellouch in 1967, an explanatory approach to trial design emphasizes hypothesis testing about the mechanisms of action of treatments under ideal conditions, whereas a pragmatic approach emphasizes testing effectiveness of two or more available treatments in real-world conditions. I…Read more

61Trust based obligations of the state and physician-researchers to patient-subjectsJournal of Medical Ethics 32 (9): 542-547. 2006.When may a physician enroll a patient in clinical research? An adequate answer to this question requires clarification of trust-based obligations of the state and the physician-researcher respectively to the patient-subject. The state relies on the voluntarism of patient-subjects to advance the public interest in science. Accordingly, it is obligated to protect the agent-neutral interests of patient-subjects through promulgating standards that secure these interests. Component analysis is the on…Read more

61Evolving Ethical Issues in Selection of Subjects for Clinical ResearchCambridge Quarterly of Healthcare Ethics 5 (3): 334-345. 1996.Wittgenstein, in his famous critique of philosophy, noted that the influence of an idea can be such that it alters the way that we see the world. “It is like a pair of glasses on our nose through which we see whatever we look at,” he said. “It never occurs to us to take them off.” This view of the power of an idea suggests that the interpretation of an event, and what response this event calls for, can depend upon the view one has of the world. A person who is naive about medical facts may, for …Read more

60Will the real Charles Fried please stand up?Kennedy Institute of Ethics Journal 13 (4): 353-357. 2003.: In response to the preceding commentary by Jerry Menikoff in this issue of the Journal , the authors argue that Fried's central concern is not that randomized clinical trials (RCTs) are conducted without consent, but rather that various aspects of the design and conduct of RCTs are in tension with physicians' duties of personal care to their patients. Although Fried does argue that the existence of equipoise cannot justify failure to obtain consent from research subjects, informed consent by i…Read more

60Assay Sensitivity and the Epistemic Contexts of Clinical TrialsPerspectives in Biology and Medicine 56 (1): 1-17. 2013.In February 2010, the World Medical Association hosted an international symposium on the ethics of placebo controls in clinical trials (WMA 2010). Despite years of debate, ethicists, clinical trialists, and policy makers remain divided over the ethical acceptability of using placebos in research when a proven, effective treatment is available. The protracted nature of this problem is due, at least in part, to a perceived conflict between the opposing demands placed on clinical research by scienc…Read more

58This paper addresses three questions central to the ethical analysis of risks and potential benefits in human subjects research: 1. How was the ethical analysis of risk understood by the members of the U.S. National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research (National Commission)? 2. What conceptual framework should guide the ethical analysis of risk? 3. What changes to U.S. regulations would the implementation of such a framework require?

53PURPOSE: The offer to return research results to participants is increasingly recognized as an ethical obligation, although few researchers routinely return results. We examined the needs and attitudes of parents of children with cancer and of adolescents with cancer to the return of research results. METHODS: Seven experts in research ethics scored content validity on parent and adolescent questionnaires previously developed through focus group and phone interviews. The questionnaires were revi…Read more
