The use of placebo controls in surgical research, or ‘sham surgery’ as it sometimes described, raises a number of ethical issues. Despite such issues, sham surgery is presently being employed, albeit very rarely, in surgical research. In this paper, the ethical implications of such control groups are discussed in the context of research into various conditions, including Parkinson's Disease and arthritis. Conflicting ethical considerations include: i) patients' best interests in relation to the harms and risks involved; ii) the need for (...) more rigorous methods in surgical research, and iii) the question of patient autonomy. Contextual features which may influence the ethical acceptability of a specific sham-controlled surgical trial are discussed. (shrink)

In the research ethics literature, there is strong disagreement about the ethical acceptability of placebo-controlled trials, particularly when a tested therapy aims to alleviate a condition for which standard treatment exists. Recently, this disagreement has given rise to debate over the moral appropriateness of the principle of clinical equipoise for medical research. Underlying these debates are two fundamentally different visions of the moral obligations that investigators owe their subjects.Some commentators and ethics documents claim that physicians, whether acting as care givers (...) or researchers, have the same duty of beneficence towards their patients and subjects: namely, that they must provide optimal medical care. In discussing placebo surgery in research on refractory Parkinson's disease, Peter Clark succinctly states this view: “The researcher has an ethical responsibility to act in the best interest of subjects.”.

During the past decennium, one of the main issues discussed in research ethics has been focused on the care that should be provided to the control group in a clinical trial. This discussion is also called the standard of care debate . Current international research ethics guidelines contain a wide variety of standards for the standard of care—including the provision of the highest attainable, the best available, the best current, a proven , and an established effective treatment. In this article, (...) we systematically review the currently used standards and argue that none of the current standards is adequate to serve as a universal standard for the standard of care. Alex London has made a substantial proposal for a universal standard, but universally adopting his standard is problematic. In this article, we propose a revised version of London's standard.

One of the most important questions in the ethics of human clinical research asks what obligations investigators owe the people who enroll in their studies. Research differs in many ways from standard care - the added uncertainties, for instance, and the nontherapeutic interventions such as diagnostic tests whose only purpose is to measure the effects of the research intervention. Hence arises the question whether a physician engaged in clinical research has the same obligations toward research subjects that he owes his (...) medical patients, or whether they differ in any fundamental way.Perhaps the most common answer is that the relationship is the same. Investigators, like physicians, are said to be fiduciaries of the volunteers who enroll in research trials. Each owes the best available medical care, which means that a physician can only justify enrolling his patient in research if the study meets the requirements of clinical equipoise, namely, that there is legitimate disagreement within the medical community as to whether the standard treatment or the investigational intervention is superior.

Physician-researchers are bound by professional obligations stemming from both the role of the physician and the role of the researcher. Currently, the dominant models for understanding the relationship between physician-researchers' clinical duties and research duties fit into three categories: the similarity position, the difference position and the middle ground. The law may be said to offer a fourth.
