Evidence based medicine (EBM) is under critical debate, and person centered healthcare (PCH) has been proposed as an improvement. But is PCH offered as a supplement or as a replacement of EBM? Prima facie PCH only concerns the practice of medicine, while the contended features of EBM also include methods and medical model. I here argue that there are good philosophical reasons to see PCH as a radical alternative to the existing medical paradigm of EBM, since the two (...) seem committed to conflicting ontologies. This paper aims to make explicit some of the most fundamental assumptions that motivate EBM and PCH, respectively, in order to show that the choice between them ultimately comes down to ontological preference. While EBM has a solid foundation in positivism, or what I here call Humeanism, PCH is more consistent with causal dispositionalism. I conclude that if there is a paradigmatic revolution on the way in medicine, it is first of all one of ontology. (shrink)

BackgroundThe concept of evidence-based medicine has strongly influenced the appraisal and application of empirical information in health care decision-making. One principal characteristic of this concept is the distinction between "evidence" in the sense of high-quality empirical information on the one hand and rather low-quality empirical information on the other hand. In the last 5 to 10 years an increasing number of articles published in international journals have made use of the term "evidence-based ethics", making a (...) systematic analysis and explication of the term and its applicability in ethics important.DiscussionIn this article four descriptive and two normative characteristics of the general concept "evidence-based" are presented and explained systematically. These characteristics are to then serve as a framework for assessing the methodological and practical challenges of evidence-based ethics as a developing methodology. The superiority of evidence in contrast to other empirical information has several normative implications such as the legitimization of decisions in medicine and ethics. This implicit normativity poses ethical concerns if there is no formal consent on which sort of empirical information deserves the label "evidence" and which does not. In empirical ethics, which relies primarily on interview research and other methods from the social sciences, we still lack gold standards for assessing the quality of study designs and appraising their findings.ConclusionThe use of the term "evidence-based ethics" should be discouraged, unless there is enough consensus on how to differentiate between high- and low-quality information produced by empirical ethics. In the meantime, whenever empirical information plays a role, the process of ethical decision-making should make use of systematic reviews of empirical studies that involve a critical appraisal and comparative discussion of data.

Evidence-based medicine has been rapidly and widely adopted because it claims to provide a method for determining the safety and efficacy of medical therapies and public health interventions more generally. However, as others have noted, EBM may be riven through with cultural bias, both in the generation of evidence and in its translation. We suggest that technological and scientific advances in medicine accentuate and entrench these cultural biases, to the extent that they may invalidate the evidence (...) we have about disease and its treatment. This creates a significant ethical, epistemological and ontological challenge for medicine. (shrink)

Contesting that a debate on evidence-based health care has taken place, this article charts three paths to the future: continuing avoidance of debate by proponents of evidence-based medicine (EBM); conflict, which the EBM movement courts and critics have espoused, and dialogue. The last portal allows for integration, which would end the disagreement between EBM and its critics and make a debate unnecessary. In search of integration, I sketch a bridge whose construction requires not compromise but a (...) win- win approach. The bridge is a medicine of meaning (MOM). Consolidating multiple pillars of evidence to unify questions that are not necessarily the same for protagonists and critics of EBM, a MOM contends that the purpose or meaning of medicine is always healing and helping, and each party finds meaning in medicine by contributing to this common purpose in its own distinctive way.

Gilbert et al. have raised important questions about the empirical grounding of neuroethical analyses of the apparent phenomenon of Deep Brain Stimulation ‘causing’ personality changes. In this paper, we consider how to make neuroethical claims appropriately calibrated to existing evidence, and the role that philosophical neuroethics has to play in this enterprise of ‘evidence-based neuroethics’. In the first half of the paper, we begin by highlighting the challenges we face in investigating changes to PIAAAS following DBS, explaining (...) how different trial designs may be of different degrees of utility, depending on how changes to PIAAAS following DBS are manifested. In particular, we suggest that the trial designs Gilbert et al. call for may not be able to tell us whether or not DBS directly causes changes to personality. However, we suggest that this is not the most significant question about this phenomenon; the most significant question is whether these changes should matter morally, however they are caused. We go on to suggest that neuroethical analyses of novel neuro-interventions should be carried out in accordance with the levels of evidence hierarchy outlined by the Centre for Evidence-Based Medicine, and explain different ways in which neuroethical analyses of changes to PIAAAS can be evidence-based on this framework. In the second half of the paper, we explain how philosophical neuroethics can play an important role in contributing to mechanism-based reasoning about potential effects on PIAAAS following DBS, a form of evidence that is also incorporated into the CEBM levels of evidence hierarchy.

Background The increase in empirical methods of research in bioethics over the last two decades is typically perceived as a welcomed broadening of the discipline, with increased integration of social and life scientists into the field and ethics consultants into the clinical setting, however it also represents a loss of confidence in the typical normative and analytic methods of bioethics. Discussion The recent incipiency of "Evidence-Based Ethics" attests to this phenomenon and should be rejected as a solution to (...) the current ambivalence toward the normative resolution of moral problems in a pluralistic society. While "evidence-based" is typically read in medicine and other life and social sciences as the empirically-adequate standard of reasonable practice and a means for increasing certainty, I propose that the evidence-based movement in fact gains consensus by displacing normative discourse with aggregate or statistically-derived empirical evidence as the "bottom line". Therefore, along with wavering on the fact/value distinction, evidence-based ethics threatens bioethics' normative mandate. The appeal of the evidence-based approach is that it offers a means of negotiating the demands of moral pluralism. Rather than appealing to explicit values that are likely not shared by all, "the evidence" is proposed to adjudicate between competing claims. Quantified measures are notably more "neutral" and democratic than liberal markers like "species normal functioning". Yet the positivist notion that claims stand or fall in light of the evidence is untenable; furthermore, the legacy of positivism entails the quieting of empirically non-verifiable considerations like moral claims and judgments. As a result, evidence-based ethics proposes to operate with the implicit normativity that accompanies the production and presentation of all biomedical and scientific facts unchecked. Summary The "empirical turn" in bioethics signals a need for reconsideration of the methods used for moral evaluation and resolution, however the options should not include obscuring normative content by seemingly neutral technical measure.

Evidence-based policy is gaining support in many areas of government and in public affairs more generally. In this paper we outline what evidence—based policy is then discuss its strengths and weaknesses. In particular, we argue that it faces a serious challenge to provide a plausible account of evidence. This account needs to be at least in the spirit of the hierarchy of evidence subscribed to by evidence-based medicine (from which evidence—based (...) policy derives its name and inspiration). Yet evidence-based policy’s hierarchy needs to be tailored to the kinds of evidence relevant and available to the policy arena. The evidence required for policy decisions does not easily lend itself to randomised controlled trials (the "gold standard" in evidence-based medicine), nor, for that matter, being listed in a single all—purpose hierarchy.

This article tries to present a broad view on the values and ethicalissues that are at stake in efforts to rationalize health policy on thebasis of economic evaluations (like cost-effectiveness analysis) andrandomly controlled clinical trials. Though such a rationalization isgenerally seen as an objective and `value free' process, moral valuesoften play a hidden role, not only in the production of `evidence', butalso in the way this evidence is used in policy making. For example, thedefinition of effectiveness of medical (...) treatment or health care serviceis heavily dependent on dominant individual or social views about thegoals of the particular treatment or service. There is also a concernthat a reliance on EBM in health policy will occur at the expense ofwidely shared social values like equity and solidarity. Moreover, thereis a concern that when economic considerations and rational proceduresbecome more influential, various `outside' groups third parties likeinsurance companies and policy makers will get a stronger influence onmedical practice which may lead to a change in the patient-providerrelationship. The authors conclude that social values and patientpreference should be explicitly addressed when health policy making isbased on economic and other scientific evidence. (shrink)

ANGUS J, HODNETT E and O’BRIEN-PALLAS L. Nursing Inquiry 2003; 10: 218–228Implementing evidence-based nursing practice: a tale of two intrapartum nursing unitsDespite concerns that the rise of evidence-based practice threatens to transform nursing practice into a performative exercise disciplined by scientific knowledge, others have found that scientific knowledge is by no means the preeminent source of knowledge within the dynamic settings of health-care. We argue that the contexts within which evidence-based innovations are implemented are (...) as influential in the outcomes as the individual practitioners who attempt these changes. A focused ethnography was done in follow-up to an earlier trial that evaluated the effectiveness of a marketing strategy to encourage the adoption of evidence-based intrapartum nursing practice. Bourdieu's (1990, 1991) concepts of habitus, capital and social field were used in our refinement of the analysis of the ethnographic findings. Nursing leadership, interprofessional struggle with physicians, the characteristics of the community and the physical environment were prominent issues at all of the sites. Detailed descriptions of the sociohistorical context and of the experiences at two sites are presented to illustrate the complexities encountered when implementing innovations. (shrink)

Proponents of evidence-based medicine (EBM) provide the “hierarchy of evidence” as a criterion for judging the reliability of therapeutic decisions. EBM's hierarchy places randomized interventional studies (and systematic reviews of such studies) higher in the hierarchy than observational studies, unsystematic clinical experience, and basic science. Recent philosophical work has questioned whether EBM's special emphasis on evidence from randomized interventional studies can be justified. Following the critical literature, and in particular the work of John Worrall, I agree (...) that many of the arguments put forward by advocates of EBM do not justify the ambitious claims that are often made on behalf of randomization. However, in contrast to the recent philosophical work, I argue that a justification for EBM's hierarchy of evidence can be provided. The hierarchy should be viewed as a hierarchy of comparative internal validity. Although this justification is defensible, the claims that EBM's hierarchy substantiates when viewed in this way are considerably more circumscribed than some claims found in the EBM literature.

Evidence-based medicine was developed to ensure that health-care decisions are based on the best available research evidence. Making this evidence available to patients is supposed to increase their autonomy by putting them in a position to make better-informed choices. In this paper, I draw on work in feminist bioethics to critique EBM’s approach to involving patients in decision making, in which patients are asked merely to select their preferences among various possible treatment outcomes but are (...) not encouraged to actively contend with the effects of illness on their lives as a whole. (shrink)

Acceding to the demand that public policy should be based on “the best available evidence” can come at significant moral cost. Important policy questions cannot be addressed using “the best available evidence” as defined by the evidence-based policy paradigm; the paradigm can change the meaning of questions so that they can be addressed using the preferred kind of evidence; and important evidence that does not meet the standard defined by the paradigm can get (...) ignored. We illustrate these problems in three contexts of evidence-based policy. (shrink)

How can philosophy of science be of more practical use? One thing we can do is provide practicable advice about how to determine when one empirical claim is relevant to the truth of another; i.e., about evidential relevance. This matters especially for evidence-based policy, where advice is thin—and misleading—about how to tell what counts as evidence for policy effectiveness. This paper argues that good efficacy results (as in randomized controlled trials), which are all the rage now, are (...) only a very small part of the story. To tell what facts are relevant for judging policy effectiveness, we need to construct causal scenarios about will happen when the policy is implemented. (shrink)

Proponents of evidence-based medicine have argued convincingly for applying this scientific method to medicine. However, the current methodological framework of the EBM movement has recently been called into question, especially in epidemiology and the philosophy of science. The debate has focused on whether the methodology of randomized controlled trials provides the best evidence available. This paper attempts to shift the focus of the debate by arguing that clinical reasoning involves a patchwork of evidential approaches and that the (...) emphasis on evidence hierarchies of methodology fails to lend credence to the common practice of corroboration in medicine. I argue that the strength of evidence lies in the evidence itself, and not the methodology used to obtain that evidence. Ultimately, when it comes to evaluating the effectiveness of medical interventions, it is the evidence obtained from the methodology rather than the methodology that should establish the strength of the evidence.

Public policymakers and institutional decision-makers routinely face questions about whether interventions “work”: does universal basic income improve people’s welfare and stimulate entrepreneurial activity? Do gated alleyways reduce burglaries or merely shift the crime burden to neighbouring communities? What is the most cost-effective way to improve students’ reading abilities? These are empirical questions that seem best answered by looking at the world, rather than trusting speculations about what will be effective. Evidence-based policy (EBP) is a movement that concretizes this (...) intuition. It maintains that policy should be based on evidence of “what works.” Not any evidence will do, however. Following on the heels of its intellectual progenitor, evidence-based medicine (EBM), EBP insists on the use of high-quality evidence produced in accordance with rigorous methodological standards. Though intuitively compelling, EBP has attracted significant criticism from methodologists, political scientists, and philosophers. This chapter provides a critical overview of EBP through a philosophical lens, reviewing and discussing some of the most pressing challenges that EBP faces and outlining some proposals for improving it. I first provide a brief overview of EBP and distinguish a broader and narrower understanding of it. I then review existing lines of criticism of EBP, two of which are considered in detail. The first elaborates how EBP struggles with extrapolation, that is, the use of evidence from study populations to make inferences about the effects of policies on novel target populations. The second maintains that EBP’s methodological tenets are deeply entwined with moral and political values, which can threaten EBP’s promise to promote objectivity in policymaking. Finally, I make some proposals for how EBP could be improved going forward. (shrink)

Evidence-based medicine (EBM) puts forward a hierarchy of evidence for informing therapeutic decisions. An unambiguous interpretation of how to apply EBM's hierarchy has not been provided in the clinical literature. However, as much as an interpretation is provided proponents suggest a categorical interpretation. The categorical interpretation holds that all the results of randomised trials always trump evidence from lower down the hierarchy when it comes to informing therapeutic decisions. Most of the critical replies to EBM react (...) to this interpretation. While proponents of EBM can avoid some of the problems raised by critics by suitably limited the claims made on behalf of the hierarchy, further problems arise. If EBM is to inform therapeutic decisions then a considerably more restricted, and context dependent interpretation of EBM's hierarchy is needed. (shrink)

In this paper we set out to examine thearguments for and against the claim thatEvidence-Based Medicine (EBM) will improve thequality of care. In particular, we examine thefollowing issues.

Evidence-based psychiatry (EBP) has arisen through the application of evidence-based medicine (EBM) to psychiatry. However, there may be aspects of psychiatric disorders and treatments that do not conform well to the assumptions of EBM. This paper reviews the ongoing debate about evidence-based psychiatry and investigates the applicability, to psychiatry, of two basic methodological features of EBM: prognostic homogeneity of clinical trial groups and quantification of trial outcomes. This paper argues that EBM may not be (...) the best way to pursue psychiatric knowledge given the particular features of psychiatric disorders and their treatments. As a result, psychiatry may have to develop its own standards for rigour and validity. This paper concludes that EBM has had a powerful influence on how psychiatry investigates and understands mental disorders. Psychiatry could influence EBM in return, reshaping it in ways that are more clinically useful and congruent with patients’ needs. (shrink)

Evidence‐based practice (EBP) first appeared on the healthcare horizon just over a decade ago. In 2003 its presence has intensified and extended beyond its initial relation to medicine embracing as it does now, nursing and the allied health disciplines. In this paper, I contend that its appearance and subsequent growth and development are the effects of potent ‘regimes of truth’, four of which bear the names: positivism, empiricism, pragmatism and economic rationalism. My aim is to show how EBP (...) generates the controversy it does because its nature and methods are inextricably interwoven with the way it has become politicised and professionalised. This exegesis is an attempt to outline how the combined effects of the four forms of rationality mentioned above allow for both the methods and objectives of EBP to be constructed as they are, while at the same moment producing the particular effects of knowledge and power in terms of who sells and who buys the idea of EBP in the culture of contemporary healthcare.

At first glance, Moritz Geiger’s reaction to Husserl’s Ideas I appears to be neither systematically articulated nor particularly original. Geiger talks about Husserl’s idealism in Ideas I in just a few passages from his book Die Wirklickheit der Wissenschaften und die Metaphysik, and in a short essay in praise of Alexander Pfänder, Alexander Pfänders Methodische Stellung. There, Geiger seems to follow a general line of criticism shared by several so-called early phenomenologists, and most fully articulated by Jean Hering, Roman Ingarden, (...) Theodor Celms and Max Scheler. In this paper I argue that Geiger’s reaction to Ideas I contains some well-developed and original contributions to phenomenological thought. In particular, I defend three theses. First, Geiger’s criticism of Husserl’s idealism is much more original and sophisticated than it at first appears, because it rests on a complex phenomenology of “attitudes” [Einstellungen]. Second, Geiger offers a unique account of phenomenology as a variation of “stance” [Haltung], rather than a variation of attitude. Third, Geiger points to an alternative kind of phenomenology, which I call certainty-based phenomenology as opposed to an evidence-based phenomenology. Elements of this certainty-based phenomenology can be found in thinkers such as Merleau-Ponty and Ricoeur, but many of their views are significantly anticipated by Geiger. (shrink)

The literature has recognised the fundamental role of teaching business ethics to students earning business administration degrees, but it is hard to find a methodology for teaching this topic successfully. We propose a new management tool—evidence-based administration—for the study of business ethics. The method developed on the basis of this management tool provides a practical vision to the students, motivates them, and favours the development of multiple facets of their education.

The question what scientific progress means for a particular domain such as medicine seems importantly different from the question what scientific progress is in general. While the latter question received ample treatment in the philosophical literature, the former question is hardly discussed. I argue that it is nonetheless important to think about this question in view of the methodological choices we make. I raise specific questions that should be tackled regarding scientific progress in the medical sciences and demonstrate their importance (...) by means of an analysis of what evidence-based medicine (EBM) has, and has not, to offer in terms of progress. I show how critically thinking about EBM from the point of view of progress can help us in putting EBM and its favoured methodologies in the right perspective. My conclusion will be that blindly favouring certain methods because of their immediately tangible short-term benefits implies that we parry the important question of how best to advance progress in the long run. This leads us to losing sight of our general goals in doing research in the medical sciences. (shrink)

Evidence-Based Medicine (EBM) is defined as the conscious, and judicious use of current best evidence in making decisions about the care of individual patients. The greater the level of evidence the greater the grade of recommendation. This pioneering explicit concept of EBM is embedded in a particular view of medical practice namely the singular nature of the patient-physician relation and the commitment of the latter towards a specific goal: the treatment and the well being of his (...) or her client. Nevertheless, in many European countries as well as the United States, this integration of the best evidence from systematic research with clinical expertise and patient values appears to be re-interpreted in light of the scarcity of healthcare resources. The purpose of this paper is double. First, to claim that from an ethical perspective EBM should be a guideline to clinical practice; and second, that in specific circumstances EBM might be a useful tool in macro-allocation of healthcare resources. Methodologically the author follows Norman Daniels' theory of democratic accountability to justify this assumption. That is, choices in healthcare must be accountable by democratic procedures. This perspective of distributive justice is responsible for the scope and limits of healthcare services. It follows that particular entitlements to healthcare — namely expensive innovative treatments and medicines —may be fairly restricted as long as this decision is socially and democratically accountable and imposed by financial restrictions of the system. In conclusion, the implementation of EBM, as long as it limits the access to drugs and treatments of unproven scientific results is in accordance with this perspective. The use of EBM is regarded as an instrument to facilitate the access of all citizens to a reasonable level of healthcare and to promote the efficiency of the system. (shrink)

It is important and urgent to question therelationship between evidence-based medicineand power shifts in health care systems.Although definitions of EBM are phrased as ascientific approach to medicine, EBM is anormative concept: it aims to improve medicineand health care. Both proponents and opponentsuse a normative concept. More particularly,they provide particular views on positions,responsibilities, possibilities, norms andrelationships between professionals, patientgroups, governments and other parties in healthcare and society. From this perspective, wewant to analyse the role of EBM in modernwestern societies. (...) By using citizenshiptheory, we will argue that the role of EBM isnot fixed but depends on the relation betweenstate and society. We will first analyse thefundamental change in western societies duringthe past decades, from modern to post-modernsocieties. Then, we will elaborate a fourfoldmodel of possible relationships between stateand society, and discuss the issue of how EBM mayfit in, by giving some examples of the practiceof EBM in different European countries. On thisbasis, we conclude to consider EBM as a publicforum where proponents and opponents of EBMdiscuss diverse and possibly conflicting waysof changing medicine, health care, and healthpolicy. This requires the incorporation of theperspective of citizens and their socialnetworks, professionals with practical andtacit knowledge, and diverse public views onwhat is regarded as `a good life'. Inasmuch asEBM is expected to be practically relevant, itought to be tied to rather than separated fromthe normative world of emancipated patients anddiverse health care practices. Proponents andopponents of EBM should be prepared to defendthe normative claims and power effects that areinherently tied to any presentation ofevidence. (shrink)

This paper explores the reasons why the notion of 'evidence-based' practice has gained prominence in educational research.

These implications are discussed in relation to the close parallel between the major components of the evidence-based framework and (...) the current Ethical Principles of Psychologists and Code of Conduct. The evidence-based framework is discussed as an ideology that promotes lifelong learning and best prepares graduate students for ethical clinical practice throughout their careers as psychologists.

“Evidence based medicine” is often seen as a scientific tool for quality improvement, even though its application requires the combination of scientific facts with value judgments and the costing of different treatments. How this is done depends on whether we approach the problem from the perspective of individual patients, doctors, or public health administrators. Evidence based medicine exerts a fundamental influence on certain key aspects of medical professionalism. Since, when clinical practice guidelines are created, costs affect (...) the content of EBM, EBM inevitably becomes a form of rationing and adopts a public health point of view. This challenges traditional professionalism in much the same way as managed care has done in the US. Here we chart some of these major philosophical issues and show why simple solutions cannot be found. The profession needs to pay more attention to different uses of EBM in order to preserve the good aspects of professionalism. (shrink)

L’ Evidence-Based Medicine (EBM) est définie comme « l’utilisation consciencieuse et judicieuse des meilleures données actuelles de la recherche clinique dans la prise en charge personnalisée de chaque patient ». L’EBM met en œuvre des standards de qualité du plus haut niveau par le tri actif de toutes les études cliniques disponibles. D’un côté, elle remet en question le fondement des savoirs pratiques basé sur l’intuition, l’expérience clinique et le mécanisme des maladies. D’un autre, elle refuse l’autorité des (...) experts et leurs recommandations. Si l’intention de l’EBM d’améliorer la pratique clinique est louable, elle ne peut résoudre la question cruciale de l’expertise clinique. En se concentrant sur les études cliniques, l’EBM oublie que le savoir clinique nécessite de rassembler plusieurs formes de savoirs. Dès lors, il manque à l’EBM une connaissance tacite, non formalisable, qu’elle rejette pour son absence supposée d’objectivité. L’expertise clinique comme incorporation de gestes à la fois intellectuels et techniques nécessite un travail de synthèse entre les connaissances implicites et explicites afin de revenir à son but : le soin au patient dans sa particularité.

Decisions in healthcare are made against the background of cultural and philosophical definitions of disease, sickness and illness. These concepts or definitions affect both health policy and research , as well as individual encounters between patients and physicians . It is therefore necessary for evidence-based medicine to consider whether any of the definitions underlying research prior to the hierarchisation of knowledge are indeed compatible with its own epistemological principles.

Toward evidence‐based policy decisions: a case study of nursing health human resources in Ontario, CanadaThis paper reflects how health services research ‘evidence’ was used to influence decisions in the province of Ontario, Canada. The process involved interaction among a variety of stakeholders and decision‐makers with researchers to reduce uncertainty and to substantiate emerging service provision issues in the province. The issues presented here focus specifically on an analysis of the nursing situation completed in 1998 for the Minister (...) of Health’s Nursing Task Force, which examined key issues in service delivery. The issues were: restructured work environments; nurse supply and declining enrollments; labour trends and utilization of the nursing workforce; patient acuity and complexity of work environments and the influence on workload; and the paucity of reliable and valid data bases for analysis of nursing’s contribution to the health system. Ontarians can be confident that the Task Force recommendations were born from solid research‐based evidence and now the challenge becomes to monitor the implementation of these resolutions over time.

Evidence-based medicine (EBM) has long deemphasized mechanistic reasoning and pathophysiological rationale in assessing the effectiveness of interventions. The EBM+ movement has challenged this stance, arguing that evidence of mechanisms and comparative studies should both be seen as necessary and complementary. Advocates of EBM+ provide a combination of theoretical arguments and examples of mechanistic reasoning in medical research. However, EBM+ proponents have not provided recent examples of how downplaying mechanistic reasoning resulted in worse medical results than would have (...) occurred otherwise. Such examples are necessary to make the case that EBM+ responds to a problem in clinical practice that urgently demands a solution. In light of this, we examine the failed rollout of efavirenz as a first-line HIV treatment in Zimbabwe as evidence of the importance of mechanistic reasoning in improving clinical practice and public health policy decisions. We suggest that this case is analogous to examples commonly given to support EBM. (shrink)
