This essay explores the role of informal logicand its application in the context of currentdebates regarding evidence-based medicine. This aim is achieved through a discussion ofthe goals and objectives of evidence-basedmedicine and a review of the criticisms raisedagainst evidence-based medicine. Thecontributions to informal logic by StephenToulmin and Douglas Walton are explicated andtheir relevance for evidence-based medicine isdiscussed in relation to a common clinicalscenario: hypertension management. This essayconcludes with a discussion on the relationshipbetween clinical reasoning, rationality, andevidence. It is argued that (...) informal logic hasthe virtue of bringing explicitness to the roleof evidence in clinical reasoning, and bringssensitivity to understanding the role ofdialogical context in the need for evidence inclinical decision making.

Evidence-based medicine has beendefined as the conscientious and judicious useof current best evidence in making clinicaldecisions. This paper will attempt to explicatethe terms ``conscientious'''' and ``judicious''''within the evidence-based medicine definition.It will be argued that ``conscientious'''' and``judicious'''' represent virtue terms derived fromvirtue ethics and virtue epistemology. Theidentification of explicit virtue components inthe definition and therefore conception ofevidence-based medicine presents an importantstarting point in the connection between virtuetheories and medicine itself. In addition, aunification of virtue theories andevidence-based medicine will illustrate theneed for (...) future research in order to combinethe fields of virtue-based approaches andclinical practice.

This paper explores the relationship between concepts of probability and hermeneutics. It seeks to examine the relationship between subjective (Bayesian) views of probability and hermeneutic descriptions of understanding. It is argued that Gadamer'saccount of the prejudicial nature of understanding, derived from Heidegger'sanalysis of foreunderstanding, offers a provocative model of clinical reasoning. The implications of this model for evidence-based medicine are discussed in conclusion.

As health care embraces the tenets of evidence-based medicine it is important to ask questions about how evidence is produced and interpreted. This essay explores normative dimensions of evidence production, particularly around issues of setting the tolerable level of uncertainty of results. Four specific aspects are explored: what health care providers know about statistics, why alpha levels have been set at 0.05, the role of randomization in the generation of sufficient grounds of belief, and the role of observational studies. The (...) essay concludes with recommendations to acknowledge the value permeation of outcome measures and suggests that attention to reasoning and argument analysis can augment traditional evidence-based approaches in providing a robust critical approach to medical knowledge.

Are restrictive measures and duties to care ethically reasonably acceptable to faith-based organizations? This study describes the perceptions of individually interviewed spiritual leaders of the disease control measures used during the recent SARS outbreak in Toronto. Four central themes were identified: the relationship between religious obligation and civic responsibilities; the role of faith-based organizations in supporting public health restrictive measures; the reciprocal obligations of public health and religious communities during restrictions; and justifiable limits to duties to care. We conclude that, (...) within certain constraints, spiritual leaders find restrictive measures ethically reasonable and that spiritual leaders can play an important role during pandemic and epidemic control planning. Public health officials should therefore include them in the early and ongoing deliberations of the criteria and logistics for implementation during public health emergencies. (shrink)

Medical technologies and assistive devices such as ventilators and power wheelchairs are designed to sustain life and/or improve functionality but they can also contribute to stigmatization and social exclusion. In this paper, drawing from a study of ten men with Duchenne muscular dystrophy, we explore the complex social processes that mediate the lives of persons who are dependent on multiple medical and assistive technologies. In doing so we consider the embodied and emplaced nature of disability and how life is lived (...) through bodies coupled with technologies and experienced as 'techno-body-subjects in situ'. Normative implications for theory and research, including bioethics research, are discussed. (shrink)
