In this paper I am concerned with risk–benefit analysis; that is, the comparison of the risks of a situation to its related benefits. We all face such situations in our daily lives and they are very common in medicine too, where risk–benefit analysis has become an important tool for rational decision-making. This paper explores risk–benefit analysis from a logical point of view. In particular, it seeks a better understanding of the common view that decisions should be made by weighing risks (...) against benefits and that an option should be chosen if its benefits outweigh its risks. I devote a good deal of this paper scrutinizing this popular view. Specifically, I demonstrate that this mode of reasoning is logically faulty if “risk” and “benefit” are taken in their absolute sense. But I also show that arguing in favour of an action because its benefits outweigh its risks can be valid if we refer to incremental risks and benefits. (shrink)

The present and future rapid increase in the hospital population of geriatric patients is discussed with particular reference to the problem of advanced brain degeneration. The consequences of various clinical management options are outlined and it is suggested that extreme attempts either to preserve or terminate life are medically, morally and socially unacceptable. The preservation of life in senile patients has important economic consequences. In achieving a decision on the medical management of patients with advanced brain decay it is suggested (...) that substantial help would be derived from: knowledge of the previously declared wishes of individual patients; improvements in geriatric assessments; broader consultation with relatives, and greater use of inter-disciplinary discussion in the preparation of criteria for terminating medical efforts to maintain survival.

A dissociated area of medical research warrants bioethical consideration: a proposed transplantation of a donor’s entire body, except head, to a patient with a fatal degenerative disease. The seeming improbability of such an operation can only underscore the need for thorough bioethical assessment: Not assessing a case of such potential ethical import, by showing neglect instead of facing the issue, can only compound the ethical predicament, perhaps eroding public trust in ethical medicine. This article discusses the historical background of full-body (...) transplantation, documents the seriousness of its current pursuit, and builds an argument for why prima facie this type of transplant is bioethically distinct. Certainly, this examination can only be preliminary, indicating what should be a wide and vigorous discussion among practitioners and ethicists. It concludes with practical suggestions for how the medical and bioethics community may proceed with ethical assessment. (shrink)
