Clinical decisionmaking includes reasoning from prescientific or scientific theories, reasoning from uncontrolled or controlled experience, and reasoning based on empathic understanding and moral beliefe. The development of contemporary clinical thinking is discussed, and it is found that successive generations of medical practitioners have had different views of the rationality and relative importance of these modes of reasoning: that which is considered rational by one generation of doctors is sometimes denounced by the next. The author's book, Rational Diagnosis and Treatment (...) , which is an example of clinical thinking in the 1960s and early 70s, is used to illustrate one particular view of clinical decisionmaking.

ABSTRACTMedical diagnosis is sometimes used by critical realists and others as an exemplar of a form of inference across time in which a current empirical observation points backwards to the conditions of its emergence and forwards to a possible future outcome or progression. Accordingly, its practice warrants critical exploration to confirm its legitimacy as a philosophical reference point. The strengths and weakness of the exemplar are appraised using case brief case studies. The limitations of medical diagnosis are discussed (...) in the wider context of the sociology of medical knowledge, the social determinants of ill-health and the role of commercial interests in shaping diagnostic practice. The conclusion is cautious, not nihilistic. Diachronic inference in medicine, as in other disciplines working in and with open systems, can be respected for its advantages to humanity. However, this brings with it the perennial caution of epistemic humility and a needed tolerance of uncertainty.. (shrink)

The aim of this essay is to elaborate philosophical and ethical underpinnings of posthumous diagnosis of famous historical figures based on literary and artistic products, or commonly called retrospective diagnosis. It discusses ontological and epistemic challenges raised in the humanities and social sciences, and attempts to systematically reply to their criticisms from the viewpoint of clinical medicine, philosophy of medicine, particularly the ontology of disease and the epistemology of diagnosis, and medical ethics. The ontological challenge focuses on (...) the doubt about the persistence of a disease over historical time, whereas the epistemic challenge disputes the inaccessibility of scientific verification of a diagnosis in the past. I argue that the critics are in error in conflating the taxonomy of disease and the act of diagnosing a patient. Medical diagnosis is fundamentally a hypothesis-construction and an explanatory device that can be generated under various degrees of uncertainty and limited amount of information. It is not an apodictic judgment as the critics presuppose, but a probabilistic judgment with varying degrees of plausibility under uncertainty. In order to avoid this confusion, I propose that retrospective diagnosis of a historical figure be syndromic without identifying underlying disease, unless there is justifiable reason for such specification. Moreover it should be evaluated not only from the viewpoint of medical science but also in a larger context of the scholarship of the humanities and social sciences by its overall plausibility and consistency. On the other hand, I will endorse their concerns regarding the ethics and professionalism of retrospective diagnosis, and call for the need for situating such a diagnosis in an interdisciplinary scope and the context of the scholarship of the historical figure. I will then enumerate several important caveats for interdisciplinary retrospective diagnosis using an example of the retrospective diagnosis of Socrates for his life-long intermittent neurologic symptoms. Finally, I will situate the present argument in a larger context of the major debate among the historians of medicine and paleopathologists, and discuss the similarities and differences. (shrink)

Now in its fourth edition, Rational Diagnosis and Treatment: Evidence-Based Clinical Decision - Making is a unique book to look at evidence-based medicine and the difficulty of applying evidence from group studies to individual patients._ The book analyses the successive stages of the decision process and deals with topics such as the examination of the patient,_the reliability of clinical data, the logic of diagnosis, the fallacies of uncontrolled therapeutic experience and the need for randomised clinical trials and meta-analyses. (...) It is the main theme of the book that, whenever possible, clinical decisions must be based on the evidence from clinical research, but the authors also explain the pitfalls of such research and the problems involved in applying evidence from groups of patients to the individual patient._ For this new edition, the sections on placebo and meta-analysis and on alternative medicine have been thoroughly updated, and there is more focus on insufficient reporting of harms of interventions. The sections on different research designs describe advantages and limitations, and the increased medicalisation and the effects of cancer screening on health people are noted. A section on academic freedom when clinicians collaborate with industry and ghost authors is added._ This essential reference work integrates the science and statistical approach of evidence-based medicine with the art and humanism of medical practice; distinguishing between data, sets of data, knowledge and wisdom, and their application. Such an intellectually challenging book is ideal for both medical students and doctors who require theoretical and practical clinical skills to help ensure that they apply theory in practice.

A diagnostic process is an investigative process that takes a clinical picture as input and outputs a diagnosis. We propose a method for distinguishing diagnoses that are warranted from those that are not, based on the cognitive processes of which they are the outputs. Processes designed and vetted to reliably produce correct diagnoses will output what we shall call ‘warranted diagnoses’. The latter are diagnoses that should be trusted even if they later turn out to have been wrong. Our (...) work is based on the recently developed Cognitive Process Ontology and further develops the Ontology of General Medical Science. It also has applications in fields such as intelligence, forensics, and predictive maintenance, all of which rely on vetted processes designed to secure the reliability of their outputs. (shrink)

1. GENERAL The term "diagnostics" refers to the general theory of diagnosis, not to the study of specific diagnoses but to their general framework. It borrows from different sciences and from different philosophies. Traditionally, the general framework of diagnostics was not distinguished from the framework of medicine. It was not taught in special courses in any systematic way; it was not accorded special attention: students absorbed it intuitively. There is almost no comprehensive study of diagnostics. The instruction in (...) class='Hi'>diagnosis provided in medical schools is exclusively specific. Clinical instruction includes (in addition to vital background information, such as anatomy and physiology) specific instruction in nosology, the theory and classification of diseases, and this includes information on diagnoses and prognoses of diverse diseases. What is the cause of the neglect of diagnostics, and of its integrated teaching? The main cause may be the prevalence of the view of diagnostics as part-and parcel of nosology. In this book nosology is taken as a given, autonomous field of study, which invites almost no comments; we shall freely borrow from it a few important general theses and a few examples. We attempt to integrate here three studies: ll of the way nosology is used in the diagnostic process; of the diagnostic process as a branch of applied ethics; ~ of the diagnostic process as a branch of social science and social technology.

Diagnosis of dementia in primary care is both difficult and important. The recommendations by several authors to improve the diagnosis of dementia by general practitioners are important, but insufficient. It is argued that perhaps the disease concept in itself is a cause of confusion for clinicians. Primary care physicians need an adapted procedure, gradually leading to the final diagnosis of dementia. It has to be a stepwise labelling strategy, using global descriptions and non-disease specific labels in the (...) beginning, ending up with well-defined disease criteria. In this process, there is circularity: previous diagnoses have to be kept in mind because symptoms and signs may gradually change during the progression of the disease, leading to reconsideration of previous deleted options. To frame this properly, the primary care physician needs to adopt a broad frail elderly geriatric concept. Implementation of this concept not only helps the diagnostic process, but also stimulates the care for dementing patients and their caregivers. Relevant arguments for early diagnostic involvement of primary care physicians can be put forward on condition that a new concept, adapted procedures and adapted instruments are used. (shrink)

Este artículo esboza una suerte de impresión diagnóstica de la figura del filósofo. Aunque esta tarea pueda convocar a otras ramas del conocimiento humano, no constituye un estudio psicológico de personalidad ni mucho menos la propuesta para una nueva nosología.

Si se habla (...) de diagnosis, se hace en un sentido figurado más que clínico. Si se habla de especie, es desde la lógica aristotélica. Y para responder a la pregunta cómo es un filósofo, de entre todos sus exponentes, Nietzsche se erige como la principal guía, ya que fue él quien resumió con un adjetivo, de gran polivalencia metafórica, cómo es, cómo ha de ser, un filósofo: un intempestivo.

ABSTRACT:How does the diagnosis process work? This essay traces the philosophical underpinnings of diagnosis from Hume through Kant, Peirce, and Popper, analyzing how pathologists amalgamate sensibility, intuition, and imagination to form new hypotheses that can be tested by evidence and experience.

In this paper I argue that ethics and evidence are intricately intertwined within the clinical practice of differential diagnosis. Too often, when a disease is difficult to diagnose, a physician will dismiss it as being “not real” or “all in the patient’s head.” This is both an ethical and an evidential problem. In the paper my aim is two-fold. First, via the examination of two case studies (late-stage Lyme disease and Addison’s disease), I try to elucidate why this kind (...) of dismissal takes place. Then, I propose a potential solution to the problem. I argue that instead of dismissing a patient’s illness as “not real,” physicians ought to exercise a compassionate suspension of judgment when a diagnosis cannot be immediately made. I argue that suspending judgment has methodological, epistemic, and ethical virtues and therefore should always be preferred to patient dismissal in the clinical setting. (shrink)

Two versions of the argument that prenatal diagnosis discriminates against the disabled are distinguished and analysed. Both are shown to be inadequate, but some valid concerns about the social effects of prenatal diagnosis are highlighted.

The purpose of this paper is to offer a diagnosis and a resolution to generality problem. I state the generality problem and suggest a distinction between criteria of relevance and what I call a theory of determination. The generality problem may concern either of these. While plausible criteria of relevance would be convenient for the externalist, he does not need them. I discuss various theories of determination, and argue that no existing theory of determination is plausible. This provides a (...) case for the no determination view: there are no facts that determine relevant types. This is the diagnosis of the generality problem. The externalist, however, may embrace the no determination view. This is what provides a resolution to the generality problem. (shrink)

The Diagnosis Confirmation Model includes a dual-pricing mechanism designed to support value-based pricing of novel antibiotics while improving the alignment of financial incentives with their optimal use in patients at high risk of drug-resistant infections. DCM is a market-based model and complementary to delinked models. Policymakers interested in stimulating antibiotic innovation could consider tailoring the DCM to their reimbursement systems and incorporating it into the suite of incentives to improve the economics of antibiotics.

Prenatal diagnosis challenges the issue of parental autonomy. Two ethical aspects of the parental decision making process with reference to PND have been taken into consideration: the duty to know and the right not to know. Whilst the first approach has been widely discussed in literature, the latter seems to be overlooked. In order to find good moral reasons supporting the right not to know, firstly the duty to know approach was critically analysed. Subsequently, the emphasis was put on (...) the unconditional parental love and the issue of child’s best interests as the features supporting parental right not to know. The clarification of what is good parenthood was presented as the best normative approach supporting the parental right not to know in case of PND. Apart from parental autonomy, raising the question of the right not to know is important in the debate about the place and role of people with disabilities in society. (shrink)

Prenatal Diagnosis (PD) includes diagnostic procedures carried out during the antenatal period, together with Preconception Screening (PS) of prospective parents, and prenatal genetic diagnosis (PGD). The purpose of all these procedures is to provide prospective parents with opportunities to decide whether or not to have a child who will be diseased or disabled. Selection decisions determine what kinds of children are brought into existence; the ability to make these decisions is of huge ethical significance. It raises connected questions (...) about discrimination, the social status of disabled people and the medicalisation of disability; patient vulnerability and the power of the medical and counselling professions to influence decision-making; and the conceptualisation of selection as a public health measure and even as eugenic. In this paper, I outline the ethical issues raised by prenatal diagnosis and describe some of the arguments which have been elaborated in relation to the permissibility of selecting against (and occasionally for) diseases and disabilities. I conclude that there are no good arguments against the prevention of disability through PD but that providing adequate information for decision-making and facilitating uncoerced individual decisions requires further attention.

In The Anticipatory Corpse, Jeffrey Bishop claims that modern medicine has lost formal and final causality as the dead body has become epistemologically normative, and that a singular focus on efficient and material causality has thoroughly distorted modern medical practice. Bishop implies that the renewal of medicine will require its housing in alternate social spaces. This essay critiques both Bishop’s diagnosis and therapy by arguing, first, that alternate social imaginaries, though perhaps marginalized, are already present within the practice of (...) medicine. And second, the essay argues that alternate social imaginaries in medicine can be reclaimed not through separatist communities but in the re-narration of conceptually underdetermined practices. Given Bishop’s invitation for theology to engage medicine, this essay then draws from theologian Dietrich Bonhoeffer for the kind of diagnosis and therapy currently needed, concluding with a contemporary example of how an alternate social imaginary is being instantiated in modern medicine.

In this chapter, our focus is the role played by notions of rationality in the diagnosis of mental disorders, and in the practice of overriding patient autonomy in psychiatry. We describe and evaluate different hypotheses concerning the relationship between rationality and diagnosis, raising questions about what features underpin psychiatric categories. These questions reinforce widely held concerns about the use of diagnosis as a justification for overriding autonomy, which have motivated a shift to mental incapacity as an alternative (...) justification. However, this approach too has recently been criticized from a mental disability rights perspective. Our analysis of the relationship between mental capacity and rationality is used to illuminate these concerns, and to investigate further the relationship between rationality and psychiatric diagnosis.

Definitive diagnosis of malaria requires the demonstration through laboratory tests of the presence within the patient of malaria parasites or their components. Since malaria parasites can be present even in the absence of malaria manifestations, and since symptoms of malaria can be manifested even in the absence of malaria parasites, malaria diagnosis raises important issues for the adequate understanding of disease, etiology and diagnosis. One approach to the resolution of these issues adopts a realist view, according to (...) which the needed clarifications will be derived from a careful representation of the entities on the side of the patient which form the ultimate truthmakers for clinical statements. We here address a challenge to this realist approach relating to the diagnosis of malaria, and show how this challenge can be resolved by appeal to Basic Formal Ontology (BFO) and to the Ontology for General Medical Science (OGMS) constructed in its terms.

Diagnosis theory reasons about incomplete knowledge and only considers the past. It distinguishes between violations and non-violations. Qualitative decision theory reasons about decision variables and considers the future. It distinguishes between fulfilled goals and unfulfilled goals. In this paper we formalize normative diagnoses and decisions in the special purpose formalism DIO(DE)2 as well as in extensions of the preference-based deontic logic PDL. The DIagnostic and DEcision-theoretic framework for DEontic reasoning DIO(DE)2 formalizes reasoning about violations and fulfillments, and is used (...) to characterize the distinction between normative diagnosis theory and (qualitative) decision theory. The extension of the preference-based deontic logic PDL shows how normative diagnostic and decision-theoretic reasoning — i.e. reasoning about violations and fulfillments — can be formalized as an extension of deontic reasoning.

Human beings rely on metaphor as a primary cognitive device for interpreting the world around them. Metaphors figure especially strongly in discourse around health, illness, and medicine. It is not just that patients use metaphors to describe their personal experience of being unwell, or that medical professionals employ metaphor to convey a diagnosis, describe a treatment, or explain the function of an organ to their patients. Metaphor, it is argued, lies at the heart of the process of diagnosis. (...) Moreover, diagnosticians employ competing metaphors in the early stages of diagnosis to speculate on alternative ways of viewing a puzzling set of symptoms. Diagnosis is often defined as a process of ordering and classifying, while metaphor is a device for playing with classifications. The medical systems of different cultures depend on different sets of fundamental metaphors. Modern Western biomedicine is organized around a series of basic metaphors: the body as machine, the body as the site of battle, and the body as a communication system. Traditional Chinese medicine, on the other hand, uses images of flow and blockage, balance and imbalance, and works by analogy with five elements: wood, fire, earth, metal, and water. Psychologists are sometimes able to detect from a patient’s own use of metaphor, or inability to use or recognize metaphor, clues to a diagnosis of psychosis or autism. With conditions such as anorexia nervosa, therapists may actually work to modify the dysfunctional metaphors by which patients depict themselves, with the purpose of establishing positive metaphors for envisaging recovery.

In clinical medicine, a diagnosis can offer an explanation of a patient's symptoms by specifying the pathology that is causing them. Diagnoses in psychiatry are also sometimes presented in clinical texts as if they pick out pathological processes that cause sets of symptoms. However, current evidence suggests the possibility that many diagnostic categories in psychiatry are highly causally heterogeneous. For example, major depressive disorder may not be associated with a single type of underlying pathological process, but with a range (...) of different causal pathways, each involving complex interactions of various biological, psychological, and social factors. This paper explores the implications of causal heterogeneity for whether psychiatric diagnoses can be said to serve causal explanatory roles in clinical practice. I argue that while they may fall short of picking out a specific cause of the patient's symptoms, they can nonetheless supply different sorts of clinically relevant causal information. In particular, I suggest that some psychiatric diagnoses provide negative information that rules out certain causes, some provide approximate or disjunctive information about the range of possible causal processes, and some provide causal information about the relations between the symptoms themselves.

Electromechanical actuators are more and more widely used as actuation devices in flight control system of aircrafts and helicopters. The reliability of EMAs is vital because it will cause serious accidents if the malfunction of EMAs occurs, so it is significant to detect and diagnose the fault of EMAs timely. However, EMAs often run under variable conditions in realistic environment, and the vibration signals of EMAs are nonlinear and nonstationary, which make it difficult to effectively achieve fault diagnosis. This (...) paper proposed a fault diagnosis method of electromechanical actuators based on variational mode decomposition multifractal detrended fluctuation analysis and probabilistic neural network. First, the vibration signals were decomposed by VMD into a number of intrinsic mode functions. Second, the multifractal features hidden in IMFs were extracted by using MFDFA, and the generalized Hurst exponents were selected as the feature vectors. Then, the principal component analysis was introduced to realize dimension reduction of the extracted feature vectors. Finally, the probabilistic neural network was utilized to classify the fault modes. The experimental results show that this method can effectively achieve the fault diagnosis of EMAs even under diffident working conditions. Simultaneously, the diagnosis performance of the proposed method in this paper has an advantage over that of EMD-MFDFA method for feature extraction. (shrink)

Fast and effective detection of the causative agent of malaria in humans, protozoan Plasmodium parasites, is of crucial importance for increasing the effectiveness of treatment and to control a devastating disease that affects millions of people living in endemic areas.

However, there is a high demand for alternative diagnostic methods that are simple, fast, highly sensitive, ideally do not rely on blood‐drawing and can potentially be (...) conducted by the patients themselves. Here, the history of Plasmodium detection is discussed, and advantages and disadvantages of diagnostic methods that are currently being applied are assessed. (shrink)

In the area known as model-based diagnosis, a system is described by-means of a set of formulas together with assumptions that all the components are functioning correctly. When we observe a behavior of the system which is inconsistent with the system description, we must relax some of the assumptions. In previous work, we have presented operations of belief change which only affect the relevant part of a belief base. In this paper, we propose the application of the same strategy (...) to the problem of model-based diagnosis. We Erst isolate the subset of the system description which is relevant for a given observation. By doing this, we reduce the size of the problem and then solve the diagnosis problem for the relevant subset. (shrink)

Medicine maintains a distinction between the medical symptom -- the patient''ssubjective experience and expression, and the privileged medical sign -- the objective findings observable by the doctor. Although the distinction is not consistently applied, it becomes clearly visible in the undefined, medically unexplained disorders of women patients. Potential impacts of genderized interaction on the interpretation of medical signs are addressed by re-reading the diagnostic process as a matter of social construction, where diagnosis results from human interpretation within a sociopolitical (...) context. The discussion is illustrated by a case story and empirical evidence of the gendering in the doctor-patient relationship. The theoretical analysis is supported by semiotic perspectives of bodily signs, feminist theory on experience, and Foucault''sideas about medical perception and gaze, and concludes that a medical diagnosis is seldom a biological fact, but the outcome of a process where biological, cultural and social elements are interwoven. Further deconstruction of the chain of signs from a feminist perspective, assigning validity to the voice of the woman patient, might broaden the understanding of women''shealth, illness and disease.

Self-diagnosis in psychiatry is where individuals diagnose themselves rather than rely upon official diagnosticians to supply a psychiatric diagnosis. The accuracy of self-diagnosis is a contested topic. In this paper, I outline what arguments are needed to see self-diagnosis as accurate and how different approaches to self-diagnosis require different arguments. I show how different arguments are required to justify accuracy for an autistic individual judging they are autistic compared to non-autistic individuals judging they are not (...) autistic. Different arguments are required if a self-diagnosing individual accepts or rejects official diagnostic criteria. Finally, different arguments are required depending upon whether diagnoses are seen as objective entities, the product of theoretical virtues or practically useful groupings. All these approaches require unique arguments to justify the accuracy of self-diagnosis. Identifying the required arguments for different approaches is a stepping stone toward establishing whether those arguments and which of those arguments can be successfully justified. (shrink)

This target article considers the ethical implications of providing prenatal diagnosis (PND) and antenatal screening services to detect fetal abnormalities in jurisdictions that prohibit abortion for these conditions. This unusual health policy context is common in the Latin American region. Congenital conditions are often untreated or under-treated in developing countries due to limited health resources, leading many women/couples to prefer termination of affected pregnancies. Three potential harms derive from the provision of PND in the absence of legal and safe (...) abortion for these conditions: psychological distress, unjust distribution of burdens between socio-economic classes, and financial burdens for families and society. We present Iran as a comparative case study where recognition of these ethical issues has led to the liberalization of abortion laws for fetuses with thalassemia. We argue that physicians, geneticists and policymakers have an ethical and professional duty of care to advocate for change in order to ameliorate these harms. (shrink)

Most of us want to have children. We want them to be healthy and have a good start in life. One way to achieve this goal is to use preimplantation genetic diagnosis . PGD enables people engaged in the process of in vitro fertilisation to acquire information about the genetic constitution of an early embryo. On the basis of this information, a decision can be made to transfer embryos without genetic defects to the uterus and terminate those with genetic (...) defects.1However, is it morally acceptable to use PGD to reduce the probability of children with severe genetic diseases being born? Is the current routine use of PGD in public healthcare services to select against severe genetic diseases like anencephaly, spina bifida, cystic fibrosis and Down’s syndrome morally acceptable?These are complex questions involving a range of difficult ethical issues—for instance, critical discussions about the morality of embryo research and embryo termination.2 They also involve awkward conceptual issues concerning such matters as the meaning of words such as “disability”3 and “severe” in “severe genetic diseases”,4 which will not be discussed here.In this paper I examine an argument which aims to show that efforts to prevent the birth of severely disabled children using PGD are morally unacceptable. Essentially, this argument appeals to our concern for disabled people and the belief that PGD, through a slippery slope process, will have bad consequences for them. I conclude that the argument is problematic for a number of reasons. But before I examine the argument itself, it will be helpful to separate two types of slippery slope argument since these involve different kinds of reasoning.TWO TYPES OF ARGUMENTMany of the arguments against PGD point to the bad consequences it can be expected to have for disabled people.

Computer-based diagnostic systems are widely regarded as having only a supportive role in assisting physicians make diagnostic decisions. Continuing progress in the design of diagnostic software, however, may not only produce systems which have heuristic and consultative value, but which may render the traditional role of the physician as a ‘polyfunctional practitioner’ obsolete should it become feasible to replace practitioner-dependent diagnostic skill with more accurate, reliable and cost-effective computer-based programs. Should the implementation of such programs prove to be both a (...) more practical and beneficial alternative than continuing to rely upon the exercise of practitioner-specific diagnostic skill, it would be unethical if the traditional role of the physician qua diagnostician were not phased out and supplanted by a more modular approach to medical decision making.

In lieu of an abstract, here is a brief excerpt of the content:Hypatia 16.3 (2001) 172-176 [Access article in PDF] Book Review Diagnosis: Difference: The Moral Authority of Medicine Diagnosis: Difference: The Moral Authority of Medicine. By Abby L. Wilkerson. Ithaca: Cornell University Press, 1998. In this compact volume, Abby Wilkerson makes several important contributions to the burgeoning literature of feminist (bio)ethics by providing substantive arguments in support of some of the key intuitive beliefs that are central to (...) much feminist bioethics thinking. Most centrally, she carefully fleshes out a feminist case for re-framing traditional bioethics approaches to the relation between health and justice. Particularly valuable is her richly detailed argument establishing the importance of bringing to the realm of health and health care Iris Marion Young's (1990) important insight that justice involves far more than questions of distribution.At the same time, Wilkerson demonstrates another major feminist tenet: that ethics and epistemology are intimately related. This connection is developed [End Page 172] through a second major theme in which she systematically tracks medicine's tendency to extend its accepted epistemic authority over physical ailments into a general authority over many other aspects of life. She documents examples of medicine's success in leveraging its scientific knowledge about certain aspects of the body into a broader ideological vision through which it claims epistemic authority in the personal and moral realm. By making explicit the gaps between medical knowledge and moral knowledge, she is able to challenge the moral authority and social power that are now granted to medical experts.While these arguments are important, they are not the whole story of the book, for its message is as much about process in bioethics as it is about conclusions. Wilkerson insists that the specific perspective of the theorist affects her/his reasoning. She demonstrates the importance of this fact by using her own distinct position as a bisexual woman to make visible the implicit acceptance and perpetuation of several ideological norms by those in dominant positions in both medicine and bioethics. The central method of the book is what she calls "material-semiotic." It involves the assumption that all human experience is mediated by culture, and the body (specifically the medicalized body) must be recognized as a political site subject to a variety of social values. We must, therefore, attend to the cultural meanings of health and illness and explore the ways that society labels and responds to these conditions. This requires investigation of the specific bodily (material) effects of these meanings in both individual and social experience.The book begins with the epistemological frame of the argument in which Wilkerson claims that medicine is deeply infected by the values and biases of the dominant culture, including its tendencies towards sexist, racist, classist, homophobic, and ablist attitudes. She explores ways in which medical theory and practice stigmatize bodily experiences common to women (in gynecology, obstetrics, and the treatment of victims of sexual or domestic violence). Medicalizing so many aspects of women's experience has the effect of obscuring women's subjective experiences and replacing them with medicine's normative perspectives of appropriate psychological norms. Moreover, the norm of femaleness promoted is a heterosexual, middle class, white variety such that other forms of social difference (e.g., non-white, non-heterosexual) must then also be medicalized and stigmatized; that is, the medical model requires explanations of difference that render pathological most variations on the privileged norm. Hence, alternative sexualities, like differences in class, abilities, race, and gender are interpreted through a medical lens that is thoroughly value-laden. In such ways, the epistemological authority granted to medicine is conflated into an unjustified form of moral authority. Although similar biases are common to every powerful social institution in the United States, they are especially pernicious within medicine because of the enormous influence it exerts in shaping knowledge about the nature of difference between social [End Page 173] groups. This immense social power may be directed towards reducing inequalities and promoting social justice, but, all too often, it is used to convey beliefs and norms that serve the interests of the privileged.Wilkerson's criticism is not reserved...

Today, French public debate and bioethics research reflect an ongoing controversy about eugenics. The field of reproductive medicine is often targeted as pre-implantation genetic diagnosis (PGD), prenatal diagnosis, and prenatal detection are accused of drifting towards eugenics or being driven by eugenics considerations. This article aims at understanding why the charge against eugenics came at the forefront of the ethical debate. Above all, it aims at showing that the charge against prenatal diagnosis is groundless. The point of (...) view presented in this article has been elaborated jointly by a geneticist and a philosopher. Besides a survey of the medical, bioethical, philosophical and social sciences literature on the topic, the methodology is founded on a joint analysis of geneticist’s various consults. Evidence from office visits demonstrated that prenatal diagnosis leads to case-by-case decisions. As we have suggested, this conclusion does not mean that prenatal diagnosis is devoid of ethical issues, and we have identified at least two. The first is related to the evaluation of a decision to abort. The second line of ethical questions arises from the fact that the claim for “normality” hardly hides normative and ambiguous views about disability. As a conclusion, ethical dilemmas keep being noticeable in the field of reproductive medicine and genetic counselling, but an enquiry about eugenic tendencies probably does not allow us to understand them in the proper way.

The article draws on historical, sociological and first-person perspectives regarding psychiatric diagnosis in order to emphasise the conceptual—and potentially ethical—benefits of ambivalence vis-à-vis the achievements and problems of psychiatric diagnosis.

Despite several decades of debate, the concept of disease remains hotly contested. The debate is typically cast as one between naturalism and normativism, with a hybrid view that combines elements of each staked out in between. In light of a number of widely discussed problems with existing accounts, some theorists argue that the concept of disease is beyond repair and thus recommend eliminating it in a wide range of practical medical contexts. Any attempt to reframe the ‘disease’ discussion should answer (...) the more basic sceptical challenge, and should include a meta-methodological critique guided by our pragmatic expectations of what the disease concept ought to do given that medical diagnosis is woven into a complex network of healthcare institutions. In this paper, we attempt such a reframing, arguing that while prevailing accounts do not suffer from the particular defects that prominent critics have identified, they do suffer from other deficits—and this leads us to propose an amended hybrid view that places objectivist approaches to disease on stronger theoretical footing, and satisfies the institutional-ethicaldesiderataof a concept of disease in human medicine. Nevertheless, we do not advocate a procrustean approach to ‘disease’. Instead, we recommend disease concept pluralism between medical and biological sciences to allow the concept to serve the different epistemic and institutional goals of these respective disciplines.

Psychiatrists diagnose mental illness in patients against a climate of opinion in which the value of diagnosis is questioned and non-medical formulations of the problems of psychiatric patients are put forward.

They may also object to standard methods of treatment. Given this situation the right of the patient to a full explanation of the (...) diagnosis and the rationale of the treatment offered seems to be incontrovertible. If this information were given to patients it would, in addition, help them to make sense out of their often puzzling experiences and indicate that fellow sufferers existed. (shrink)

The public, mental health consumers, as well as mental health practitioners wonder about what kinds of values mental health professionals hold, and what kinds of values influence psychiatric diagnosis. Are mental disorders socio-political, practical, or scientific concepts? Is psychiatric diagnosis value-neutral?

Alarm over the prospect that prenatal diagnostic techniques, which permit identification of fetal sex and facilitate abortion of healthy but unwanted female fetuses has led some to urge their outright prohibition. This article argues against that response. Prenatal diagnosis permits timely action to preserve and enhance the life and health of fetuses otherwise endangered, and, by offering assurance of fetal normality, may often encourage continuation of pregnancies otherwise vulnerable to termination. Further, conditions in some societies may sometimes render excusable (...) the inclination to abort certain healthy female fetuses. In places where abortion for fetal sex alone is recognised as unethical, however, medical licensing authorities already possess the power to discipline, for professional misconduct, physicians who prescribe or perform prenatal diagnosis purely to identify fetal sex, or those who disclose fetal sex when that is unrelated to the fetus's medical condition.

The paper is devoted to develop a connection between the Sozialphilosophie of Axel Honneth and Plato’s Republic. The main point is that Honneth’s research of a non formal theory of justice, connected with the idea of good life or eudaimonia, which permits a diagnosis of social pathologies, finds fecund confluences in the Plato’s doctrine.

In this paper I present an argument in favour of a parental duty to use preimplantation genetic diagnosis (PGD). I argue that if embryos created in vitro were able to decide for themselves in a rational manner, they would sometimes choose PGD as a method of selection. Couples, therefore, should respect their hypothetical choices on a principle similar to that of patient autonomy. My thesis shows that no matter which moral doctrine couples subscribe to, they ought to conduct the (...) PGD procedure in the situations when it is impossible to implant all of the created embryos and if there is a significant risk for giving birth to a child with a serious condition. (shrink)

Definitive diagnosis of malaria requires the demonstration through laboratory tests of the presence within the patient of malaria parasites or their components. Since malaria parasites can be present even in the absence of malaria manifestations, and since symptoms of malaria can be manifested even in the absence of malaria parasites, malaria diagnosis raises important issues for the adequate understanding of disease, etiology and diagnosis. One approach to the resolution of these issues adopts a realist view, according to (...) which the needed clarifications will be derived from a careful representation of the entities on the side of the patient which form the ultimate truthmakers for clinical statements. We here address a challenge to this realist approach relating to the diagnosis of malaria, and show how this challenge can be resolved by appeal to Basic Formal Ontology (BFO) and to the Ontology for General Medical Science (OGMS) constructed in its terms.

This paper explores the bioethical issues associated with the diagnosis and treatment of vulvar cancer for Indigenous women in East Arnhem Land, Northern Territory, Australia. Based on a qualitative study of a vulvar cancer cluster of Indigenous women, the article highlights four main topics of bioethical concern drawn from the findings: informed consent, removal of body parts, pain management, and issues at the interface of Indigenous and Western health care. The article seeks to make a contribution towards Indigenous health (...) and bioethics and bring to light areas of further research. (shrink)

The objective of the paper is to implement and validate diagnosis in the medical field via refined neutrosophic fuzzy logic (RNFL). As such, we have proposed a Max-Min composition (MMC) method in RNFL. This method deals with the diagnosis under certain constraints like uncertainty and indeterminacy. Further, we have considered the diagnosis problems to validate the sensitivity analysis of the novel multi attribute decision-making technique. Finally, we gave the graphical representations and compared the obtained results with other (...) existing measures in refined neutrosophic fuzzy sets. (shrink)

Prenatal diagnosis utilizes invasive procedures such as amniocentesis, chorionic villus sampling, cord blood sampling and pre-implantation genetic diagnosis. These techniques can diagnose serious foetal illnesses and this therefore provides valuable information to couples, helping them to prepare for the birth of an affected child. It also affords women the freedom to decide whether to terminate a pregnancy. The selective termination of foetuses with serious disabilities does not represent disability discrimination because women and parents are actually rejecting the disability, (...) rather than the foetus itself More significantly, the choice to abort a foetus with a serious illness or disability is an intensely private and personal exercise that does not and cannot be reflective of a wider public morality. Exactly the same can be said of the choice to selectively abort foetuses based solely on their sex. The private choice of women in this respect does not amount to the social devaluation of women. Firstly, it is an erroneous assumption that women in Australia prefer male babies. Secondly, even if there is a preference for male babies, banning prenatal sex selection would be treating just one of many symptoms of sexism, rather than curing the primary causes. The moral right of all women to reproductive freedom is an embodiment of their equal value in society. (shrink)

The goal of this article is to present the possibility of using Diagnosis- Related Groups (DRG) in the hospital management process and to analyse the need for business performance management on the part of hospital management staff. The following research methods were used: literature analysis, case studies, and poll analysis. It is not possible to increase the effectiveness of operation of healthcare entities without increasing the importance of IT systems and using DRG more effectively in the management process. Training (...) users in IT and the use of DRGs is important to achieving hospital effectiveness. The increased importance of analyses and planning in a hospital should be reflected in the organisational structure of service providers. Hospital controllers should have a similar role to those present in most companies in other industries. (shrink)

In 1947, the Cornell psychiatrist Keeve Brodman and a handful of colleagues began developing what would become one of the most widely used health questionnaires of its time—the Cornell Medical Index (CMI). A rigidly standardized form, the CMI presented 195 yes-no questions designed to capture the health status of “the total patient.” Over the following decades, Brodman’s project of standardizing medical history taking gradually evolved into a project of mathematizing and computerizing diagnosis: out of the CMI grew the Medical (...) Data Screen (MDS), one of the first computerized methods of deriving diagnoses from patient data. This essay follows the life course of these tools through the second half of the twentieth century. It argues for a genealogy of biomedical computing and computerized diagnosis that takes more seriously the continuities between computer-based digital practices and paper-based analog ones. The computerized MDS evolved from, and rested upon, paper data practices associated with questionnaires and surveys. The interlocking histories of the CMI and the MDS prompt a reconsideration of the material and temporal parameters within which the history of computerized medicine has conventionally been understood.

No apologies are needed for returning to the subject of brain death and its definition. There has been so much public discussion that it is important for public confidence that the issues should be clarified. In the following two contributions - one from a professor of neurosurgery and the other from a lawyer - an attempt is made to convince doctors (if that is needed) and lay people alike that what appears to be a new bogy is not one at (...) all but a confusion of thought arising from the use of new technology to treat brain-damaged patients. This, however, might not be the view of Mr Skegg (Journal of medical ethics, 2, 190) who, fearful of the situation, has argued for a statutory definition of death. Professor Jennett discusses the findings of a conference of the Royal Colleges of the United Kingdom which met to try and remove uncertainty surrounding the diagnosis of brain death. In his view the Colleges' document is to be welcomed for `its authority and its practicality' and `should lead to more humane medical practice'. Mr Kennedy, from a legal position, comes to the same conclusion, that with a good code of practice, as advocated by the Royal Colleges, no legislation is called for. (shrink)

Progress in recombinant DNA technology and in mapping of the human genome makes it possible to diagnose genetic defects as early as 8–10 weeks after conception for an increasing number of genetic diseases. Further developments will bring wider applicability and increased sensitivity, making widespread application of this type of diagnosis possible. Logistical and ethical problems will however arise in the course of this development.
