Theoretical Medicine

Professional autonomy is often described as a claim of professionalsthat has to serve primarily their own interests. However, it can also beseen as an element of a professional ideal that can function as astandard for professional, i.e. medical practice. This normativeunderstanding of the medical profession and professional autonomy facesthree threats today. 1) Internal erosion of professional autonomy due toa lack of internal quality control by the medical profession; 2)the increasing upward pressure on health care expenses that calls for ahealth care policy that could imply limitations for the professionalautonomy of physicians; 3) a distorted understanding of theprofession as being based on a formal type of knowledge and relatedtechnology, in which other normative dimensions of medical practice areneglected and which frustrates meaningful communication betweenphysicians and patients. To answer these threats a normative structureanalysis of medical practice is presented, that indicates whichprinciples and norms are constitutive for medical practice. It isconcluded that professional autonomy, normatively understood, should bemaintained to avoid the lure of the technological imperative and toprotect patients against third parties' pressure to undertreatment.However, this professional autonomy can only be maintained if members ofthe profession subject their activities and decisions to a criticalevaluation by other members of the profession and by patients and ifthey continue to critically reflect on the values that regulate today'smedicine.

Some nonparametric allocation methods are proposed for use in computer-aided medical diagnostics. It may be expected that the replacement of the widely employed parametric models by these methods leads to more realistic results, because the assumptions which are used by parametric models and which are never fulfilled in practice become unnecessary. The overestimation of the discriminating power arising from the non-fulfillment of parametric assumptions are avoided.

Psychiatric researchers typically assume that the modelling of psychiatric symptoms is not influenced by psychiatric categories; symptoms are modelled and then grouped into a psychiatric category. I highlight this primarily through analysing research domain criteria (RDoC). RDoC’s importance makes it worth scrutinizing, and this assessment also serves as a case study with relevance for other areas of psychiatry. RDoC takes inadequacies of existing psychiatric categories as holding back causal investigation. Consequently, RDoC aims to circumnavigate existing psychiatric categories by directly investigating the causal basis of symptoms. The unique methodological approach of RDoC exploits the supposed lack of influence of psychiatric categories on symptom modelling, taking psychiatric symptoms as the same regardless of which psychiatric category is employed or if no psychiatric category is employed. But this supposition is not always true. I will show how psychiatric categories can influence symptom modelling, whereby identical behaviours can be considered as different symptoms based on an individual’s psychiatric diagnosis. If the modelling of symptoms is influenced by psychiatric categories, then psychiatric categories will still play a role, a situation which RDoC researchers explicitly aim to avoid. I discuss four ways RDoC could address this issue. This issue also has important implications for factor analysis, cluster analysis, modifying psychiatric categories, and symptom based approaches.

Những thay đổi động trong hệ thống chăm sóc sức khỏe của Mỹ sâu sắc hơn nhiều so với sự phát triển công nghệ đơn thuần. Người tiêu dùng, các bác sĩ và các nhà bảo hiểm bên thứ ba đều đang đảm nhận những vai trò mới trong hệ thống. Cân bằng quyền kiểm soát y tế đang bị thay đổi một cách căn bản. Trừ khi ba bên này hợp tác với nhau trong một quan hệ đối tác chung, những cải tiến cần thiết sẽ không xảy ra và những điều hiện tại tốt đẹp trong hệ thống sẽ bị mất đi. Chìa khóa cho mối quan hệ đối tác quan trọng này chính là người tiêu dùng.

In an article recently published in this journal, I raised a puzzle about the control of genetic information, suggesting a situation in which it might turn out that we have a duty to remain in ignorance about at least some aspects of our own genome. In this article, I propose a way that would make sense of how the puzzle arises, and offer a way to resolve it and similar puzzles in future: in essence, we would consider genetic information to be something the distribution of which may be more or less just. We would not know in advance what a just distribution would be, though, and in some cases there might still be a justice-based reason to deny a person genetic information about himself. However, others might also have justice-based claims to be able to access that information. This suggests that there is a possible world in which one person is entitled to at least some genetic information about another, while that other person—to whom the information refers—is not, and that this world would be just.

The development of the philosophy of medicine in the Federal Republic of Germany since 1945 is presented in a thematic form. The first two decades were characterized by the evolution of an anthropological school of thought that aimed at relating physician and patient in a more personal and existential form than had hitherto been the case. In the last years, this tendency to demand deeper psychic and broader social involvement with medical problems had increased. Somatic disorders were considered to be fundamentally caused by socially induced mental stress. After a brief period during which the theme of organisms in general and phenomenologically grasped living-body of human beings in particular were discussed, there followed since the mid-seventies an essential preoccupation with the methodology and epistemology of medicine. According to this trend, medicine is to be analyzed in terms of the theory of action, with its conceptual and strategic orientation towards practice and not, as generally believed, towards the standards of scientific truth. The concepts of disease, diagnosis and therapy are therefore relative and their validity is dependent on time, persons and circumstances involved. Thus, the highest criteria of utility for medical actions cannot but be the affected patient and society.
