Mediating the meaning of evidence through epistemological diversity Nursing's disciplinary recognition of ‘multiple ways of knowing’ reflects an epistemological diversity that supports nursing praxis. Nursing as praxis offers a conceptual way to explore what it is about the interface of practice, knowledge and evidence in nursing that distinguishes us as a discipline. I suggest that the relationship between evidence and knowledge is defined and mediated by the same epistemological diversity that supports nursing as praxis. Just as the meaning and truth‐value (...) of evidence is evaluated from within the body of existing disciplinary knowledge, new evidence may prompt an evaluation of the meaning and truth‐value of extant nursing knowledge. Nursing practice that relies on scientific evidence as a singular basis of practice knowledge is susceptible to exploitation by the diverse agendas operating within an ideology of evidence‐based practice and the healthcare system. Mediating the meaning of evidence for nursing practice through acknowledgement of the diverse epistemologies that underpin nursing knowledge will contribute to a disciplinary‐specific definition of what constitutes evidence for nursing, and will better direct how evidence is integrated into a disciplinary body of knowledge.

Philosophers and others have questioned whether or not expertise in morality is possible. This debate is not only theoretical, but also affects the perceived legitimacy of clinical ethicists. One argument against moral expertise is that in a pluralistic society with competing moral theories no one can claim expertise regarding what another ought morally to do. There are simply too many reasonable moral values and intuitions that affect theory choice and its application; expertise is epistemically uniform. In this article, we discuss (...) how similar concerns have recently threatened to undermine expertise in medicine and science. In contrast, we argue that the application of values is needed to exercise medical, scientific, and moral expertise. As long as these values are made explicit, worries about a pretense to authority in the context of a liberal democracy are ill-conceived. In conclusion, we argue for an expertise that is epistemically diverse. (shrink)

This paper explores some of the important parallels between recent reforms to legal rules for the admissibility of scientific and expert evidence, exemplified by the US Supreme Court's decision in Daubert v Merrell Dow Pharmaceuticals, Inc. in 1993, and similar calls for reforms to medical practice, that emerged around the same time as part of the Evidence-Based Medicine (EBM) movement. Similarities between the “movements” can be observed in that both emerged from a historical context where the quality of medicine and (...) legal approaches to science were being subjected to growing criticism, and in the ways that proponents of both movements have used appeals to “folk epistemologies” of science to help legitimate their reform aspirations. The term folk epistemology is used to describe the weaving together of formal and informal images of scientific method with normative and pragmatic concerns such as eradicating “junk science”, and promoting medical best practice. Perhaps unsurprisingly, given the unfocused breadth of these aspirations the implications of these “reforms” for medical and legal practice have not been straightforward, although they do represent an important new set of rhetorical resources to critique and or legitimate expertise in medical and legal domains. Discussion closes, by noting the growth of calls for these movements to reciprocate in areas where law and medicine intersect, such as medical negligence litigation. (shrink)

Good medical practice requires evidence of effectiveness to address deficits in care, strive for further improvements, and justly apportion finite resources. Nevertheless, the potential of palliative care is still held back by a paucity of good evidence. These circumstances are largely attributable to perceived ethical challenges that allegedly distinguish dying patients as a special client class. In addition, practical limitations compromise the quality of evidence that can be obtained from empirical research on terminally ill subjects.This critique aims to appraise the (...) need for focused research, in order to develop clinical and policy decisions that will guide health care professionals in their care of dying patients. Weighted against this need are tenets that value the practical and ethical challenges of palliative care research as unique and insurmountable. The review concludes that, provided investigators compassionately apply ethical principles to their work, there is no justification for not endeavouring to improve the quality of palliative care through research.
