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. 相似文献

Evidence-based medicine has been defined as the conscientious and judicious use of current best evidence in making clinical decisions. This paper will attempt to explicate the terms "conscientious" and "judicious" within the evidence-based medicine definition. It will be argued that "conscientious" and "judicious" represent virtue terms derived from virtue ethics and virtue epistemology. The identification of explicit virtue components in the definition and therefore conception of evidence-based medicine presents an important starting point in the connection between virtue theories and medicine itself. In addition, a unification of virtue theories and evidence-based medicine will illustrate the need for future research in order to combine the fields of virtue-based approaches and clinical practice. 相似文献

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.

Clinical research is now a global enterprise. However, research ethics capacity has lagged behind the growth and expansion
of clinical research in low and middle income countries. To address this mismatch, the Fogarty International Center of the
National Institutes of Health has created a program to fund education in research ethics. This series of articles describes
the experiences of graduates from 5 nations of the University of Toronto’s Joint Centre for Bioethics International Masters
of Health Science Program. The program has graduated 32 students to return to their institutions to build research ethics
capacity. 相似文献
