How men view genetic testing for prostate cancer risk: findings from focus groups.

OBJECTIVE: To determine the values, beliefs, and attitudes that influence a man's intention to undergo or defer genetic testing for prostate cancer risk. DESIGN: Qualitative, using focus group interviews 12 focus groups were conducted to identify key values and beliefs about genetic testing for prostate cancer risk in anticipation of its future availability. SETTING: Medium-sized, mid-west, US city. PARTICIPANTS: Community sample of 90 lay men of diverse educational, ethnic, and age backgrounds. ANALYSIS: Descriptive statistics and immersion/crystallization to identify themes and sub-themes. RESULTS: The major areas of concern were distilled into the following. THEMES: beliefs about consequences, expectations, benefits for patients, beliefs about barriers, and susceptibility concerns. CONCLUSION: Identifying these men's values will help health professionals anticipate the informational and ethical needs of patients in the informed consent process. Men will need to understand how such testing may affect their planning regarding future prostate health, and how medical information is used outside of the physician patient relationship.

Influence of religious and spiritual values on the willingness of Chinese-Americans to donate organs for transplantation.

The rate of organ donation among minority groups in the United States, including Chinese-Americans, is very low. There is currently very little data in the biomedical literature that builds on qualitative research to quantify the attitudes of Chinese Americans toward organ donation. The present study quantitatively assesses the religious and cultural reasons that Chinese-Americans appear to be less willing to donate their organs than other populations. It also seeks to determine whether Confucian, Buddhist, or Daoist ideals are a significant factor in their overall reluctance to donate organs among respondents in this sample. A questionnaire distributed to Chinese American adults asked about general feelings toward organ donation and Buddhist, Confucian, Christian, Daoist, and other spiritual objections. The results suggest that Chinese-Americans are indeed influenced by Confucian values, and to a lesser extent, Buddhist, Daoist, and other spiritual beliefs, that associate an intact body with respect for ancestors or nature. Another significant finding is that the subjects were most willing to donate their organs after their deaths, to close relatives, and then in descending order, distant relatives, people from their home country, and strangers. This 'negotiable' willingness has enormous implications for clinicians, who may be able to increase organ donation rates among Chinese-Americans by, first, recognizing their diverse spiritual beliefs, and, second, offering a variety of possibilities for the organ procurement and allocation.

Holding the present and future accountable to the past: history and the maturation of clinical ethics as a field of the humanities.

Clinical ethics, like bioethics more generally, until recently has tended to focus on the present and future, with little attention to the history of moral thought about health care that preceded bioethics. As a consequence, clinical ethics and bioethics lack maturity as fields of the humanities. The papers in this year's clinical ethics issue of the Journal put contemporary clinical ethics in critical dialogue with the past, making the former accountable to the latter. The six papers in this issue of the Journal are briefly described, with an emphasis on how they contribute to the maturation of clinical ethics as a field of the humanities.

Informed consent and neuroanatomic correlates of intentionality and voluntariness among psychiatric patients.

The authors examine the less-studied components of patients' autonomous decision making, or decisional autonomy, in the light of current research in psychiatry and neuropsychology and developments in the construct of informed consent. The three components of decisional autonomy-understanding, intentionality, and noncontrol or voluntariness-are related to clinical constructs in psychiatry and neuropsychology, in particular to executive control functions. The authors review studies that examine deficits in prefrontal cerebral function in schizophrenia, depression, and some anxiety disorders that are related to intentionality and voluntariness. Assessment of decisional autonomy should encompass evaluation of impaired intentionality and voluntariness, not simply impaired understanding. The main response to finding such impairments should be to provide treatment to ameliorate them. New strategies for psychiatric care should be developed to address the clinical challenges of an increasingly complex view of decisional autonomy.

Clinical and ethical implications of impaired executive control functions for patient autonomy.

The authors identify the clinical and ethical implications of impaired executive control functions for patient autonomy. Executive control functions are processes that orchestrate relatively simple ideas, movements, or actions into complex goal-directed behavior, and impairments in these functions are becoming more common as the population ages. The authors examine difficulties that individuals with impaired executive control functions may have in making treatment decisions and describe a practical, ethically justified framework for making treatment decisions for patients with impairments in these functions. Three components of autonomy are identified-intentionality, understanding, and voluntariness. Intentionality and voluntariness are especially affected by impaired executive control functions. Impairments of these aspects of autonomy may often be overlooked when only traditional mental status examinations are employed, with adverse consequences for the health of patients wrongly thought to possess intact ability to make and carry out plans of care. Two case vignettes illustrate the complexities faced by clinicians intervening with patients who have deficits in decision-making capacity caused by impaired executive control functions.

Qualitative analysis of value judgments in interpreting cervicovaginal smears using the Bethesda system.

CONTEXT: We hypothesize that there are unrecognized value judgments that influence cytopathologists in interpreting borderline cervicovaginal smears and that these judgments contribute to the well-documented variation among cytopathologists regarding such diagnoses. OBJECTIVE: To identify and map these values. DESIGN: Survey consisting of Kodachromes and histories for 5 borderline smears. Respondents were asked to give their diagnoses, recommendations for treatment, and reasoning. RESULTS: We demonstrated a wide variation in interpretation of borderline smears similar to previous studies. We then used inductive qualitative analysis to identify the clinical reasoning and value judgments that influenced the responses. CONCLUSIONS: We mapped those diagnostic value judgments that should be used in evaluation borderline cases. We believe this map can be used to rigorously manage and standardize the use of such judgments.

Ethical challenges in the managed practice of obstetrics and gynecology.

Obstetrics and gynecology has been transformed from a fee-for-service, unmanaged system to a prepaid managed system. This change poses significant ethical challenges, which we address. We show that obstetrician-gynecologists and medical institutions are moral co-fiduciaries of female and pregnant patients, that the obstetrician-gynecologist should be economically disciplined without capitulating to managed care, and that managed care organizations have an obligation to support the medical education and research from which they benefit.

Ethics in fetal medicine.

In this chapter we provide an overview of current ethical issues in fetal medicine. We begin with an introduction to the language and concepts of ethics. We then show how ethical principles can be applied to fetal medicine. In this part of the chapter we introduce the concept of the fetus as a patient and explain its implications for directive versus non-directive counselling. We then take up two current clinical controversies, routine obstetric ultrasound and termination of third trimester pregnancy.

A basic concept in the clinical ethics of managed care: physicians and institutions as economically disciplined moral co-fiduciaries of populations of patients.

Managed care employs two business tools of managed practice that raise important ethical issues: paying physicians in ways that impose conflicts of interest on them; and regulating physicians' clinical judgment, decision making, and behavior. The literature on the clinical ethics of managed care has begun to develop rapidly in the past several years. Professional organizations of physicians have made important contributions to this literature. The statements on ethical issues in managed care of four such organizations are considered here, the American Medical Association, the American College of Physicians, the American College of Obstetricians and Gynecologists, and the American Academy of Pediatrics. Three themes common to these statements are identified and critically assessed: the primacy of meeting the medical needs of each individual patient; disclosure of conflicts of interest in how physicians are paid; and opposition to gag orders. The paper concludes with an argument for a basic concept in the clinical ethics of managed care: physicians and institutions as economically disciplined moral co-fiduciaries of populations of patients.

Hume's influence on John Gregory and the history of medical ethics.

The concept of medicine as a profession in the English-language literature of medical ethics is of recent vintage, invented by the Scottish physician and medical ethicist, John Gregory (1724-1773). Gregory wrote the first secular, philosophical, clinical, and feminine medical ethics and bioethics in the English language and did so on the basis of Hume's principle of sympathy. This paper provides a brief account of Gregory's invention and the role that Humean sympathy plays in that invention, with reference to key texts in Gregory's work. The paper also considers two interesting and perhaps provocative ways in which Hume can be read through Gregory: first, sympathy as a principle of scientific discovery in Hume's science of man and moral physiology; and sympathy as gendered feminine in Hume's moral philosophy. Hume's principle of sympathy is at the core of Gregory's medical ethics and the histories of Western medical ethics and bioethics pivot on Gregory--and, therefore, on Hume--as it does on few other figures.

Ethical consideration of maternal participation in clinical research.

This review explores some of the implications for a balanced approach to the ethics of maternal participation in clinical research, from the perspective of the fetus as a patient, which is a central concept in obstetric ethics. The review therefore begins with an account of this topic, followed by an examination of some of its ethical implications for a balanced approach to the ethics of clinical research that involves pregnant women.

Attitudes toward neurosurgical procedures for Parkinson's disease and obsessive-compulsive disorder.

Similar neurosurgical procedures exist for Parkinson's disease (PD) and obsessive-compulsive disorder (OCD). Because PD is seen as a brain disease and OCD as a disease of the mind, neurologists and psychiatrists may be more aware of and more optimistic toward neurosurgery for PD than for OCD. A questionnaire was sent to randomized American Psychiatric Association and American Academy of Neurology members, and 569 of 1,188 eligible members (47.9%) responded. Some 82.8% of the psychiatrists and 27.4% of the neurologists were aware of neurosurgical procedures for OCD, whereas 84.7% of psychiatrists and 99.4% of neurologists were aware of neurosurgery for PD (P < 0.001). Of psychiatrists, 74.1% would refer appropriate patients for OCD neurosurgery, 67.4% for PD neurosurgery (P = 0.15); of neurologists, 25.6% would refer for OCD, 94.3% for PD (P < 0.001). Specialty affected willingness to refer for OCD neurosurgery. Specialty and degree of contact with neurosurgeons affected willingness to refer for PD neurosurgery. There is poor physician awareness of neurosurgical options for OCD compared with PD, as well as a risk-benefit bias against OCD surgery by the neurologists surveyed.

Moral authority, power, and trust in clinical ethics.

Moral concerns about the authority, power, and trustworthiness of physicians have become important topics in clinical ethics during the past three decades. These concerns have come to greater prominence with the increasing involvement of large-scale private institutions in the organization and delivery of medical services, especially managed care organizations, and with the increasing involvement of government in the payment for and organization and delivery of medical services. When physicians act as the agents of large institutions or governments. the power of physicians over their patients increases. The purposes of this article are (1) to reflect briefly on the historical origins of the moral problem of physicians' power in medicine, and (2) to introduce the articles in the 1999 annual number of the Journal of Medicine and Philosophy on topics in clinical ethics.

Ethical dimensions of ultrasound screening for fetal anomalies.

The ethical dimensions of the debate on routine ultrasound are analyzed. The central role of the informed consent process, based on a respect for the autonomy of the pregnant woman, is presented. Failure to offer quality ultrasound in clinical settings where it is available restricts access to pregnant women to the diagnosis of fetal anomalies and therefore restricts access to the options of abortion and fetal therapy. We show that beneficence- and justice-based considerations do not supersede respect for autonomy.

The physician's moral obligations to the pregnant woman, the fetus, and the child.

The moral obligations and ethical duties of health care professionals responsible for the care of a pregnant woman, a fetus, and a child are complex and evolve with gestation and birth. Well-intentioned physicians and others concerned with the interests of pregnant women and their fetuses may disagree about the moral status of the fetus and ethical duties owed to both the woman and fetus. This article lays out a framework for thinking about these issues from several perspectives.
