Despite its phenomenal success since its inception in the early nineteen-nineties, the evidence-based medicine movement has not succeeded in shaking off an epistemological critique derived from the experiential or tacit dimensions of clinical reasoning about particular individuals. This critique claims that the evidence-based medicine model does not take account of tacit knowing as developed by the philosopher Michael Polanyi. However, the epistemology of evidence-based medicine is premised on the elimination of the tacit dimension from clinical judgment. This is demonstrated through (...) analyzing the dichotomy between clinical and statistical intuition in evidence-based medicine’s epistemology of clinical reasoning. I argue that clinical epidemiology presents a more nuanced epistemological model for the application of statistical epidemiology to the clinical context. Polanyi’s theory of tacit knowing is compatible with the model of clinical reasoning associated with clinical epidemiology, but not evidence-based medicine. (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)

In an overview of the essays in this project, a number of clinical ethics issues receive emphasis. (1) One cluster concerns the ethical concerns presented within the relationship between the providers (doctor, nurse, etc.) and patient (and family), as distinct from those associated with being a clinical ethics consultant invited into a situation to assist. (2) Distinct from these are ethical issues intrinsic to the ways in which clinical encounters are variously written about (from chart notes to published articles). (3) (...) Finally, there is a set of issues connected with the major characteristics of clinical encounters, in view of which it is imperative to be specifically attentive to the fine details and complex interactions among patient, doctor, family, and others, within a specific social context. Keeping these matters in mind helps to clarify the differences between consulting (talking and listening) and writing about consultations, as well as among the various kinds of writing about clinical encounters.

Perceptions are often merely regarded as the basic elements of knowledge. They have, however, a complex structure of their own and are far from being elementary. My paper will analyze two basic patterns of perception and some of the resulting medical implications. Most basically, all object perception is characterized by a mixture of knowledge and ignorance (Husserl). Perception essentially perceives with inner and outer horizons, brought about by the kinesthetic activity of the perceiving subject (Sartre). This first layer of perceptual (...) reality, the world of open perceptions, is the inescapable background for every rationality, every value, every existence (Merleau-Ponty). On an epistemological level a characteristic change of perceptual patterns in medicine was introduced by pathological anatomy (Foucault). The reference of medical perception to the dead body created the new possibility of absolute perception, allowing for more precise medical interventions, but at the same time coming into conflict with the open structures of ordinary, non-scientific perception patterns in everyday life. On the basis of these distinctions, an analysis of the different perceptual patterns in medicine becomes possible. Such an analysis would be the task of a sub-field in medical philosophy that could be called medical aesthetics having as its goal an art of perception understood as a technique of adequately applying different perceptual patterns in medical practice.
