Disability certificates in India: a challenge to health privacy.

A "disability certificate" is necessary to access benefits afforded under the Persons with Disabilities Act (1995) in India. This paper analyses this requirement and concludes that it constitutes a major challenge to maintaining privacy of health information especially for persons with mental health disabilities in India and recommends modifications in the certificate's format and use, to reduce the magnitude of privacy infringement for those using the disability certificate to access benefits to which they are legally entitled.

Trial design and informed consent for a clinic-based study with a treatment as usual control arm.

Employing the National Institute of Mental Health-funded Prevention of Suicide in Primary Care Elderly Collaborative Trial as a case study, we discuss 2 sets of ethical issues: obtaining informed consent for a clinic-based intervention study and using treatment as usual (TAU) as the control condition. We then address these ethical issues in the context of the debate about the quality improvement efforts of health care organizations. Our analysis reveals the tension between ethics and scientific integrity involved with using TAU as a control condition and the difficulty in designing high-quality research in a community-based setting.

Treatment as usual (TAU) control practices in the PROSPECT Study: managing the interaction and tension between research design and ethics.

The use of treatment as usual (TAU) as a control condition may pose the considerable challenge of maintaining both scientific rigor and meeting high ethical standards in experiments on human subjects. The authors illustrate the tension and explore the relationship between research design and ethics, especially the interaction between the two, in the NIMH-funded PROSPECT study (Prevention of Suicide in Primary Care Elderly - Collaborative Trial). The goal of PROSPECT is to determine whether placement of a depression health specialist in primary care practices will have a favorable impact on rates of depression, hopelessness and suicidal ideation in elderly primary care patients with major or persistent minor depression. PROSPECT randomly assigns practices either to an intervention arm (which includes the provision of depression health specialists) or to an enhanced care arm (TAU, with the addition of screening and assessment services). TAU, enhanced by the provision of screening and assessment services, is to be used as a benchmark for measuring the effectiveness of PROSPECT's intervention. However, TAU in the epidemiological and clinical literature has also been linked to high rates of suicide in the elderly related to unrecognized and untreated or under-treated depression. The authors present their approach to managing the tension, or interaction, between the use of TAU for scientific and public health purposes and the requirement for beneficence, that is, the duty to assure the safety of human subjects in research and to do no harm. Through enhancements of TAU, by the provision of information to primary care physicians concerning the psychiatric status of their patients, the investigators attempt to meet the challenge of maintaining rigor and meeting high ethical standards.

Ethical concerns in the research and treatment of complex disease.

Research on and treatment of complex diseases raise familiar ethical issues concerning informed consent, privacy, confidentially, insurability, employability and social stigma. Consideration of the family as the unit of study, or point of medical intervention, presents some additional twists to these common ethical concerns. In addition, complex diseases present particular ethical challenges because different social and political incentives accompany placing emphasis on either the genetic or the environmental components of the diseases (e.g. in allocating research funds or ascribing responsibility for illness).

Breast cancer genetic screening and critical bioethics' gaze.

This paper illustrates a role that bioethics should play in developing and criticizing protocols for breast cancer genetic screening. It demonstrates how a critical bioethics, using approaches and reflecting concerns of contemporary philosophy of science and science studies, may critically interrogate the normative and conceptual schemes within which ethical considerations about such screening protocols are framed. By exploring various factors that influence the development of such protocols, including politics, cultural norms, and conceptions of disease, this paper and the critical bioethics' approach it endorses illuminate and critically assess some of the competing worldviews informing protocol development. One of the frequently neglected worldviews in traditional bioethics' treatment of protocols concerning breast care is constituted by women's own views of their breasts and breast cancer, both within the technologically-oriented social practice of American medicine and in light of the social construction of their breasted experience in American society. This paper attempts to redress and critically assess this neglect on the part of traditional bioethics. Finally, in contrast to traditional bioethics, critical bioethics critically interrogates its own normative and conceptual commitments. In this final capacity, a critical bioethics' approach makes a valuable contribution to the evolution of bioethics.

The Consortium Ethics Program: an approach to establishing a permanent regional ethics network.

This paper describes the first three-year experience of the Consortium Ethics Program (CEP-1) of the University of Pittsburgh Center for Medical Ethics, and also outlines plans for the second three-year phase (CEP-2) of this experiment in continuing ethics education. In existence since 1990, the CEP has the primary goal of creating a cost-effective, permanent ethics resource network, by utilizing the educational resources of a university bioethics center and the practical expertise of a regional hospital council. The CEP's conception and specific components stem from recognition of the need to make each hospital a major focus of educational efforts, and to provide academic support for the in-house activities of the representatives from each institution.

Bioethics for human geneticists: models for reasoning and methods for teaching.

The ethical issues raised by the Human Genome Project (HGP) and by human genetics in general are not entirely novel. In fact, the ethical issues surrounding genetic research and the provision of genetic services fit into the evolution of bioethics, a field of inquiry which has its roots in concerns of the 1970s, concerns about the dignity and self-determination of individuals and about the development of medical technologies. Although bioethics has been largely occupied with patient-centered concerns, attention is currently shifting toward socially oriented issues, such as the justice of the existing health-care system. Genetic counseling has already incorporated many of the lessons of early bioethics and, as a profession, adheres to a consultand-centered ethic which reflects the values incorporated into the doctrine of informed consent, which is a cornerstone of bioethics. The mandate of the Ethical, Legal, and Social Implications Program of the HGP--to anticipate ethical problems arising from advances in genetics and to educate the public about genetics--reflects not only the nonpaternalistic approach of early bioethics but also bioethics' increasing attention to the ethical import of systemic and institutional factors, as well as an anticipatory and preventive approach to dealing with ethical concerns. Because bioethics has so much to contribute to current consideration of ethical issues in human genetics, it is important to provide training in ethics to those working in the field. Guidelines for using a case-oriented approach are suggested.

Alpha thalassaemia in the Maori: a family study.

Twelve members of a Maori family were investigated for alpha-thalassaemia after a provisional diagnosis of thalassaemia had been made on the basis of chronic hypochromic microcytic red cell indices. Ten family members were shown to have the 3.7 kb deletion form of alpha-thalassaemia; two of these were homozygous for this deletion (-alpha/-alpha); eight had the single deletion (-alpha/alpha alpha). While anaemia was not a significant finding, the degree of hypochromicity and microcytosis correlated well with the alpha globin gene status of individual family members. This and other studies provide evidence that alpha-thalassaemia is a significant contributor to the chronic mild anaemia of the Maori.

Uptake of Tc-99m MAA by the liver during a thromboscintigram/lung scan.

A young man with a swollen left leg was referred to us for a thromboscintigram/lung scan. The unexpected visualization of the liver during the flow study after intravenous injection of Tc-99m MAA into the dorsal veins of both feet provided the clue to his underlying problem. He was shown to have extensive venous collateralization in the left pelvis, and to a lesser degree on the right, due to a large pelvic mass. This was shown to consist of metastases from a previously treated testicular carcinoma. Venous drainage from the legs was shunted into the mesenteric circulation, which them emptied into the portal vein, thereby carrying the radiopharmaceutical to the liver. No uptake was seen in the spleen.
