BackgroundExpertise has been a contentious concept in Evidence-Based Medicine. Especially in the early days of the movement, expertise was taken to be exactly what EBM was rebelling against—the authoritarian pronouncements about “best” interventions dutifully learned in medical schools, sometimes with dire consequences. Since then, some proponents of EBM have tried various ways of reincorporating the idea of expertise into EBM, with mixed results. However, questions remain. Is expertise evidence? If not, what is it good for, if anything?MethodsIn this article, I (...) describe and analyze the three historical models of expertise integration in EBM and discuss the difficulties in putting each into practice. I also examine accounts of expertise from disciplines outside of medicine, including philosophy, sociology, psychology, and science and technology studies to see if these accounts can strengthen and clarify what EBM has to say about expertise.ResultsOf the accounts of expertise discussed here, the Collins and Evans account can do most to clarify the concept of expertise in EBM.ConclusionsWith some additional clarification from EBM proper, theoretical resources from other disciplines might augment the current EBM account of expertise.

Surgery is an important part of contemporary health care, but currently much of surgery lacks a strong evidence base. Uptake of evidence-based medicine (EBM) methods within surgical research and among practitioners has been slow compared with other areas of medicine. Although this is often viewed as arising from practical and cultural barriers, it also reflects a lack of epistemic fit between EBM research methods and surgical practice. In this paper we discuss some epistemic challenges in surgery relating to this lack (...) of fit, and investigate how resources from feminist epistemology can help to characterize them. We point to ways in which these epistemic challenges may be addressed by gathering and disseminating evidence about what works in surgery using methods that are contextual, pluralistic, and sensitive to hierarchies.

Adjustments of everyday life in order to prevent disease or treat illness afflict partly unconscious preferences and cultural expectations that are often difficult to change. How should one, in medical contexts, talk with patients about everyday life in ways that might penetrate this blurred complexity, and help people find goals and make decisions that are both compatible with a good life and possible to accomplish? In this article we pursue the question by discussing how Habermas’ theory of communicative action can (...) be implemented in decision-making processes in general practice. The theory of deliberative decision-making offers practical guidelines for what to talk about and how to do it. For a decision to be rooted in patients’ everyday life it has to take into consideration the patient’s practical circumstances, emotions and preferences, and what he or she perceives as ethically right behaviour towards other people. The aim is a balanced conversation, demonstrating respect, consistency and sincerity, as well as offering information and clarifying reasons. Verbalising reasons for one’s preferences may increase awareness of values and norms, which can then be reflected upon, producing decisions rooted in what the patient perceives as good and right behaviour. The asymmetry of medical encounters is both a resource and a challenge, demanding patient-centred medical leadership, characterised by empathy and ability to take the patient’s perspective. The implementation and adjustments of Habermas’ theory in general practice is illustrated by a case story. Finally, applications of the theory are discussed. (shrink)

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.

Reflection has been proclaimed as a means to help physicians deal with medicine’s inherent complexity and remedy many of the shortcomings of medical education. Yet, there is little agreement on the nature of reflection nor on how it should be taught and practiced. Emerging neuroscientific concepts suggest that human thought processes are largely nonconscious, in part inaccessible to introspection. Our knowledge of the world is fraught with uncertainty, ignorance and indeterminacy, and influenced by emotion, biases and illusions, including the illusion (...) of not having illusions. Neuroscience also documents that lifelong learning processes may hone nonconscious cognition to high levels of sophistication, allowing rapid and precise perceptions, judgments and actions in complex situations. We argue that knowledge of mechanisms underlying human thought may be useful in designing educational programs to foster desired attributes such as curiosity, critical self-awareness and intuitive acumen in medical professionals. The juxtaposition of neuroscientific insights with ideas from Kant on reflective judgement, van Manen on tact, and Aristotle on phronésis, supports a concept of reflection that manifests as wise practice. We suggest that reflection in medical education should be an imperative for educators seeking to guide learners to manage the complexity and “messiness” of medical practice, and a role-modelling mode of medical practice characterized by self-correcting behaviors that culminate in good and right professional actions. An example illustrates reflective practice in the teaching and learning of physicianship. (shrink)

Genetic testing practices are increasingly advancing clinical medicine. This process of ‘routinisation of genetics’ has been conceived as a medical and ethical problem mainly because of the assumption that non-geneticists might lack the necessary skills to provide these services. In particular, the relevant theoretical knowledge in clinical genetics is viewed as insufficient in general practitioners and physicians from other specialities. Empirical findings seem to indicate significant variations not only in theoretical but also in practical knowledge between geneticists and non-geneticists. Several (...) fields of practical knowledge—regarding for example the focus of clinical action, the relevance of therapeutic action or the normative framework—can be identified that are or could be areas of conflict when the routinisation of genetic services proceeds. From an ethical point of view, these variations in know how and background are especially relevant whenever the respective genetic service is concerned with medical information of exceptional normative quality, such as, for example, in prenatal genetic screening and diagnosis of untreatable conditions. Here, the clinically acquired practical knowledge of the non-geneticist could be particularly misleading insofar as there is no relation to therapy and—in a narrow sense—no clinical utility to be assessed. Non-geneticists need a chance to acquire the relevant theoretical and practical knowledge in order to understand and fulfil their own duties in the respective situations in a way that secures the important rights at stake of their patients and clients.

The aim of this article is to present a conceptual review and analysis of symptom understanding. Subjective bodily sensations occur abundantly in the normal population and dialogues about symptoms take place in a broad range of contexts, not only in the doctor’s office. Our review of symptom understanding proceeds from an initial subliminal awareness by way of attribution of meaning and subsequent management, with and without professional involvement. We introduce theoretical perspectives from phenomenology, semiotics, social interactionism, and discourse analysis. Drew (...) Leder’s phenomenological perspectives deal with how symptom perception occurs when any kind of altered balance brings forward a bodily attention. Corporeality is brought to explicit awareness and perceived as sensations. Jesper Hoffmeyer’s biosemiotic perspectives provide access to how signs are interpreted to attribute meaning to the bodily messages. Symptom management is then determined by the meaning of a symptom. Dorte E. Gannik’s concept “situational disease” explains how situations can be reviewed not just in terms of their potential to produce signs or symptoms, but also in terms of their capacity to contain symptoms. Disease is a social and relational phenomenon of containment, and regulating the situation where the symptoms originate implies adjusting containment. Discourse analysis, as presented by Jonathan Potter and Margaret Wetherell, provides a tool to notice the subtle ways in which language orders perceptions and how language constructs social interaction. Symptoms are situated in culture and context, and trends in modern everyday life modify symptom understanding continuously. Our analysis suggests that a symptom can only be understood by attention to the social context in which the symptom emerges and the dialogue through which it is negotiated. (shrink)

Rufus of Ephesus's treatise Quaestiones Medicinales is unique in the known corpus of ancient medical writing. It has been taken for a procedural handbook serving an essentially operational purpose. But with its insistent message that doctors cannot properly understand and treat illnesses unless they supplement their own knowledge by questioning patients, and its distinct appreciation of the singularity of each patient's experience, Rufus's work shows itself to be no mere handbook but a treatise about the place of questioning in the (...) clinical encounter. This paper concentrates on two aspects of Rufus's thought that are unusual by comparison with other ancient medical texts: his distinctively person-centred rather than disease-based concept of questioning, and his extension of ‘habits’ beyond the dietary and occupational to include an indeterminate range of individual characteristics whose relevance to illness is not immediately obvious. In his quest for subjective information to set alongside ob.. (shrink)

What clinicians, biomedical scientists, and other health care professionals know as individuals or as groups and how they come to know and use knowledge are central concerns of medical epistemology. Activities associated with knowledge production and use are called epistemic practices. Such practices are considered in biomedical and clinical literatures, social sciences of medicine, philosophy of science and philosophy of medicine, and also in other nonmedical literatures. A host of different kinds of knowledge claims have been identified, each with different (...) uses and logics of justification. A general framework is needed to situate these diverse contributions in medical epistemology, so we can see how they fit together. But developing such a framework turns out to be quite tricky. In this survey, three possible frameworks are considered along with the difficulties associated with each of them. The essay concludes with a fourth framework, which considers any epistemology as part of a practice that is oriented toward overcoming errors that emerge in antecedently given practices where knowledge is developed and used. As medicine indirectly advances health by directly mitigating disease, so epistemology indirectly advances knowledge by directly mitigating error. (shrink)

The evidence-based medicine movement advocates basing all medical decisions on certain types of quantitative research data and has stimulated protracted controversy and debate since its inception. Evidence-based medicine presupposes an inaccurate and deficient view of medical knowledge. Michael Polanyi’s theory of tacit knowledge both explains this deficiency and suggests remedies for it. Polanyi shows how all explicit human knowledge depends on a wealth of tacit knowledge which accrues from experience and is essential for problem solving. Edmund Pellegrino’s classic treatment of (...) clinical judgment is examined, and a Polanyian critique of this position demonstrates that tacit knowledge is necessary for understanding how clinical judgment and medical decisions involve persons. An adequate medical epistemology requires much more qualitative research relevant to the clinical encounter and medical decision making than is currently being done. This research is necessary for preventing an uncritical application of evidence-based medicine by health care managers that erodes good clinical practice. Polanyi’s epistemology shows the need for this work and provides the structural core for building an adequate and robust medical epistemology that moves beyond evidence-based medicine. (shrink)

Most clinicians take for granted a simple, reductionist understanding of medical knowledge that is at odds with how they actually practice medicine; routine medical decisions incorporate more complicated kinds of information than most standard accounts of medical reasoning suggest. A better understanding of the structure and function of knowledge in medicine can lead to practical improvements in clinical medicine. This understanding requires some familiarity with epistemology, the study of knowledge and its structure, in medicine. Michael Polanyi's theory of tacit knowing (...) is advanced as the basis for developing a more accurate understanding of medical knowledge. Tacit knowing, which explores the taken-for-granted background knowledge that underlies all human knowing, is explained in detail with a focus on its relevance for clinical medicine. The implications of recognizing tacit knowing in medicine and medical decisions are discussed. These include the ability to explain the importance of the clinical encounter in medical practice, mechanisms for analysing patient and doctor as persons, and the need for humility given the uncertainty that the tacit dimension injects into all medical decisions. This more robust medical epistemology allows clinicians to better articulate the nature and importance of patient-centred care, to avoid pitfalls inherent in reductionist approaches to medical knowledge, and to think more clearly about the relationships between medicine and health care at the individual and population levels.

Effective person-centred care requires recognition of the personhood not only of patients but of practitioners. This chapter explores the consequences of this recognition for major debates in medical epistemology, regarding clinical reasoning and the relationship between research and practice. For too long these debates have been dominated by false dichotomies - subjectivity versus objectivity, judgement versus evidence, reason versus emotion. Based on flawed understandings of such core concepts as “objectivity” and “engagement”, this distorted dissection of the subject-object relationship has served (...) to depersonalise practice. The costs of this depersonalisation include over-regulation and micromanagement of healthcare processes by administrators and payers at the same time that information from clinical research remains under-utilized and the personhood of patients risks being ignored. Science is a human practice, founded in a broader conception of human reasoning, ontologically dependent on human beings living and engaging with the world in social, emotional and ethical contexts. After looking at different conceptions of epistemic hierarchies and their uses in the analysis and evaluation of reasoning in a range of practice contexts, we propose a “nested hierarchy” that effectively turns upside-down the flawed evidence hierarchies that have helped to depersonalise care. T.S. Eliot’s “wisdom, knowledge, information” scheme (to which we add “data” below “information”) provides a model for a person-centred epistemic hierarchy. This crucial, person-centred inversion represents levels of awareness that characterise more or less developed thinking and judgement on the part of the particular practitioner. (shrink)

This paper considers the view that medicine is both “science” and “art.” It is argued that on this view certain clinical knowledge – of patients’ histories, values, and preferences, and how to integrate them in decision-making – cannot be scientific knowledge. However, by drawing on recent work in philosophy of science it is argued that progress in gaining such knowledge has been achieved by the accumulation of what should be understood as “scientific” knowledge. I claim there are varying degrees of (...) objectivity pertaining to various aspects of clinical medicine. Hence, what is often understood as constituting the “art” of medicine is amenable to objective methods of inquiry, and so, may be understood as “science”. As a result, I conclude that rather than endorse the popular philosophical distinction between the art and science of medicine, in the future a unified, multifaceted epistemology of medicine should be developed to replace it.
