Motivating Donors to Genetic Research? Anthropological Reasons to Rethink the Role of Informed Consent

In this article we explore the contribution from social anthropology to the medical ethical debates about the use of informed consent in research, based on blood samples and other forms of tissue. The article springs from a project exploring donors’ motivation for providing blood and healthcare data for genetic research to be executed by a Swedish start-up genomics company. This article is not confined to empirical findings, however, as we suggest that anthropology provides reason to reassess the theoretical understanding of autonomy as generally defined by Beauchamp and Childress. Careful consideration of the trust expressed by donors through the act of donation, furthermore, suggests that there is reason to redirect the ethical scrutiny from informed consent to issues concerning institutional arrangements and social responsibility. In particular, we suggest that an anthropological approach could facilitate a reconsideration of the political implications of using informed consent as a regulatory practice in tissue-based research.     

Changing constructions of informed consent: qualitative research and complex social worlds

Informed consent is a concept which attempts to capture and convey what is regarded as the appropriate relationship between researcher and research participant. Definitions have traditionally emphasised respect for autonomy and the right to self-determination of the individual. However, the meaning of informed consent and the values on which it is based are grounded in society and the practicalities of social relationships. As society changes, so too do the meaning and practice of informed consent. In this paper, we trace the ways in which the meaning and practice of informed consent has changed over the last 35 years with reference to four qualitative studies of parenting and children in the UK which we have undertaken at different points in our research careers. We focus in particular on the shifting boundaries between the professional and personal, and changing expressions of agency and power in a context of heightened perceptions of risk in everyday life. We also discuss developments in information and communication technologies as a factor in changing both the formal requirements for and the situated practicalities of obtaining informed consent. We conclude by considering the implications for informed consent of both increasing bureaucratic regulation and increasingly sophisticated information and communication technologies and suggest strategies for rethinking and managing 'consent' in qualitative research practice.     

Ethical dilemmas of social science research on AIDS and orphanhood in Western Kenya

This paper is based on the experiences drawn from a long-term social science research programme on the impact of the AIDS pandemic on orphanhood in western Kenya. It discusses the ethical dilemma of maintaining a delicate balance between research ethics, the expectations of the study population and negotiating the community's vested interests in a health related research project in a low-income society. I argue that informed consent and the intended benefits of the study to the participants continue to be major challenges facing the justification of social research with people affected by or living with AIDS in low-income societies. The paper underscores the importance of community feedback sessions as a way of enhancing chances of acceptability of research efforts and obtaining informed consent. It further shows how community feedback sessions contribute to local knowledge of the problem being studied, creating opportunities for advocacy. This discussion adds to the existing ethical debate on the wider contexts within which research on vulnerable people affected by AIDS is conducted by arguing that research practice is inseparable from epistemological concerns of knowledge production. I suggest that ethnographers should enhance efforts to innovatively design action research projects to serve the twin purposes of data collection and deal with ethical challenges that are experienced when doing long-term research on vulnerable groups.     

Beyond informed consent

Although a relatively recent phenomenon, the role of informed consent in human research is central to its ethical regulation and conduct. However, guidelines often recommend procedures for obtaining informed consent (usually written consent) that are difficult to implement in developing countries. This paper reviews the guidelines for obtaining informed consent and also discusses prevailing views on current controversies, ambiguities and problems with these guidelines and suggests potential solutions. The emphasis in most externally sponsored research projects in developing countries is on laborious documentation of several mechanical aspects of the research process rather than on assuring true comprehension and voluntary participation. The onus for the oversight of this process is often left to overworked and ill-equipped local ethics review committees. Current guidelines and processes for obtaining informed consent should be reviewed with the specific aim of developing culturally appropriate methods of sharing information about the research project and obtaining and documenting consent that is truly informed. Further research is needed to examine the validity and user friendliness of innovations in information sharing procedures for obtaining consent in different cultural settings.     

Translating ethics: researching public health and medical practices in Nepal

Conducting anthropological research into situations where public health interventions are ongoing raises a number of complex ethical issues. This paper addresses this by focusing on recent debate around questions of informed consent in research situations into health care in the 'developing' world. Two issues are developed: firstly, that of anthropological engagement with medical research trials; and secondly, how medical ethics debates have impinged upon and influenced anthropological ideas of ethics. Drawing on personal anthropological research into the implementation of the WHO prescribed tuberculosis control programme (DOTS) in the context of Nepal, I outline a number of ethical dilemmas and issues that arose. This research context included other ongoing research into DOTS implementation, as well as the local culture of health care provision. It involved moving between a number of sites and subject positions while interacting with heath professionals and patients. In conclusion, rather than prescribing ethical norms for researchers in such situations, I argue that we need more ethnographic examples and case studies as a means of thinking through the issues. I suggest that we need to reflect on both the ethical issues that arise when undertaking research into multifaceted public health interventions and into the situations where ethical guidelines and stipulations are formulated. The best place for this may be the Internet, where we increasingly see the conditions emerging for open dialogue.     

Ethical issues in social science research with special reference to sexual behaviour research

Social science research has long been concerned with ethical issues, but agencies that review and fund research are increasingly attentive to assuring that ethical considerations are being fully addressed. Research on sexual behavior, a topic that has generated much recent attention worldwide as scientists confront the epidemics of adolescent pregnancy, AIDS and STDs, raises ethical issues that are worthy of special attention. Beginning with the philosophical origin of ethical principles that guide research, this paper discusses the key ethical issues to be considered when designing and conducting social science research. Included are special precautions for research on adolescents, the purpose and properties of an informed consent procedure, and the formation and function of an ethical review committee.     

Family consent and the pursuit of better medicines through genetic research.

Rapid changes in the science and technology related to genetic research are challenging scientists, health care providers, ethicists, regulators, patient groups, and the pharmaceutical industry to keep pace with ethically grounded, workable guidelines for both the research and clinical applications of human genetics. We describe the genetic research being conducted by one pharmaceutical company (GlaxoSmithKline) and how the company is addressing the ethical, legal, and social issues surrounding this research; discuss an industry working group's attempt to advance pharmacogenetic research by openly addressing and disseminating information on related ethical, legal, and regulatory issues; identify scientific and ethical differences among various types of genetic research; discuss potential implications of family consent on subject privacy and autonomy, data collection, and study conduct; and suggest points to consider when study sponsors, investigators, and ethics committees evaluate research proposals. Public and expert opinion regarding informed consent in genetic research is evolving as a result of increased education, discussion, and understanding of the relevant issues. Five years ago, there was strong support for anonymity in genetic research as a privacy safeguard. Now, an increasingly popular school of thought advocates against anonymity to preserve an individual's ability to withdraw and, if desired, access research results. It is important to recognize this evolution and address consent issues in a reasoned, practical, and consistent way, including input from patients and their families, health care providers, ethicists, scientists, regulatory bodies, research sponsors, and the lay community. Responsibility for assessing issues related to family consent for research should remain with local investigators, ethics boards, and study sponsors. A "one-size-fits-all" perspective in the form of new regulations, for example, would likely be a disservice to all.     

Ethical issues surrounding studies with vulnerable populations: a case study of South African street children

Researchers who investigate social and economic determinants of health often interact with vulnerable and marginalized populations. Great care must be taken to conduct research studies involving vulnerable persons in a manner consistent with accepted ethical principles in order to protect participants from exploitation, to build capacity, and to promote wellbeing. Children form a particularly vulnerable group, especially those who do not enjoy the protection of parents or guardians. METHODS: A research project which studied South African Sunnyside's street children was used as a case study to illustrate ethical issues surrounding research with vulnerable populations. DISCUSSION: The participants in the case study lacked the age of majority and were without any legal guardian. The researchers experienced considerable difficulty in obtaining ethical approval to conduct the study. The street children, at first, were not allowed to give informed consent for the study because of their minor age. Ethical principles of autonomy, disclosure, competence and understanding, consent and voluntariness, beneficence and non-maleficence, and justice are described and applied to this case study involving street children in a South African neighbourhood. It is suggested that by working within an ethical framework, the safety of research participants will be assured and the quality of the research will be enhanced.     

Proposing modesty for informed consent

The extension of informed consent into social science research has met with considerable opposition. The history and concept of informed consent, however, is based on a substantive ethical notion of the research relationship as informed and voluntary that is appropriate for social science research relationships. Yet social science research might sometimes be different from health research in ways that justify a different approach to informed consent and research relationships. Social science research tends to have a lower magnitude of risk, usually does not need to disrupt the therapeutic assumption common in health research contexts or when researchers are health professionals, and recruitment is sometimes incremental and reflects a building of trust and development of the research participant's role. These differences may sometimes justify novel approaches to the research relationship and require case-by-case evaluation to determine their relevance to establishing the informed and voluntary nature of the relationship through the use of informed consent procedures. Ultimately, respect for research participants requires social research into practices that can support or replace informed consent. The institutional role of informed consent and the goal of informed and voluntary research participation serve modest but important roles in health and social research. Their proper role in health and social research requires flexibility and experimentation, but does not justify abdication of informed consent or the notion of informed and voluntary participation.     

Ethics of Informed Consent for Pragmatic Trials with New Interventions

Objectives: Pragmatic trials evaluate the comparative benefits, risks, and burdens of health care interventions in real-world conditions. Such studies are now recognized as valuable to the perimarketing stage of drug development and evaluation, with early pragmatic trials (EPTs) being explored as a means to generate real-world evidence at the time of regulatory market approval. In this article, we present an analysis of the ethical issues involved in informed consent for EPTs, in light of the generally recognized concern that traditional ethical rules governing randomized clinical trials, such as lengthy informed consent procedures, could threaten the “real world” nature of such trials. Specifically, we examine to what extent modifications (waivers or alterations) to regulatory consent for EPTs would be ethical. Methods: We first identify broadly accepted necessary conditions for modifications of informed consent (namely, the research involves no more than minimal risk of harm, the research is impracticable with regulatory consent, and the alternative to regulatory consent does not violate legitimate patient expectations) and then apply those criteria to the premarket and early postmarket contexts. Results and Conclusions: The analysis shows that neither waivers nor alterations of regulatory consent for premarket EPTs will be ethically permissible. For postmarket EPTs with newly approved interventions, waivers of consent will be ethically problematic, but some studies might be conducted in an ethical manner with alterations to regulatory consent.     

Patients' perceptions of research in emergency settings: A study of survivors of sudden cardiac death

Conditions such as stroke, sudden cardiac death, and major traumatic injury are major causes of morbidity and mortality, and there is a need for clinical research to improve treatment for these conditions. However, because informed consent is often impossible, research in these situations poses ethical concerns. Despite growing literature on the ethics of emergency research, little is known about the views of relevant patient populations regarding research in emergency settings conducted under an exception from informed consent (EFIC).     

Gaining and maintaining consent: ethical concerns raised in a study of dying patients

This article provides a frank discussion of the practical and ethical issues that emerged during the process of setting up and conducting a participant observation study within an inpatient hospice. A general overview of the participant observation approach is used to prefigure a discussion of its strengths and weaknesses when employed as a research and evaluation tool among palliative care populations. Although participant observation provided a flexible and viable means of collecting data in the hospice, it also created a number of dilemmas that in many cases could not be satisfactorily resolved. Difficulties arose, in particular, with obtaining informed consent from patients and assuming that consent remained valid after patients had deteriorated physically and mentally. Further complications stemmed from the role conflict and ambiguity inherent within an approach that requires a researcher to work simultaneously as a participant and as an observer.     

Ethical aspects of genome diversity research: genome research into cultural diversity or cultural diversity in genome research?

The goal of the Human Genome Diversity Project (HGDP) was to reconstruct the history of human evolution and the historical and geographical distribution of populations with the help of scientific research. Through this kind of research, the entire spectrum of genetic diversity to be found in the human species was to be explored with the hope of generating a better understanding of the history of humankind. An important part of this genome diversity research consists in taking blood and tissue samples from indigenous populations. For various reasons, it has not been possible to execute this project in the planned scope and form to date. Nevertheless, genomic diversity research addresses complex issues which prove to be highly relevant from the perspective of research ethics, transcultural medical ethics, and cultural philosophy. In the article at hand, we discuss these ethical issues as illustrated by the HGDP. This investigation focuses on the confrontation of culturally diverse images of humans and their cosmologies within the framework of genome diversity research and the ethical questions it raises. We argue that in addition to complex questions pertaining to research ethics such as informed consent and autonomy of probands, genome diversity research also has a cultural–philosophical, meta-ethical, and phenomenological dimension which must be taken into account in ethical discourses. Acknowledging this fact, we attempt to show the limits of current guidelines used in international genome diversity studies, following this up by a formulation of theses designed to facilitate an appropriate inquiry and ethical evaluation of intercultural dimensions of genome research.     

A consumer perspective on informed consent and third-party issues.

Our two children were diagnosed with a rare genetic disorder, which led us to establish a research foundation. This led to in-depth consideration of issues surrounding informed consent from a consumer perspective. Third-party issues arose as central to the formulation of ethical policy in the establishment of a blood and tissue bank and an epidemiologic study. We suggest that a number of myths--privacy is possible, samples can be stripped of identifiers, humans are subjects, voluntary informed consent is attainable, genetics is about the individual only, genetic information is different than other medical information, research is altruistic, the public will learn truths about genetic research via media, and research is culturally competent--make it difficult to resolve the issues intrinsic to informed consent. A number of important elements could make policy decisions less complicated. These include conducting culturally competent research; conveying noncoercive hope, not hype; contacting the voluntary informant only; asking the informant to extend contact to other family members; requiring a comprehensive informed consent process for all contacted; and engaging in state-of-the-art data protections. There is a need for a "Genomic Hippocratic Oath," creating an ethical basis for research similar to the one vowed by health care professionals. Establishing ethical policies as a result of the collaboration of policy makers, researchers, and consumers will allow research to progress ethically at a rapid rate. If regulations are oppressive, they will thwart research; if they are too lenient, participants will not receive protections needed to participate safely.     

Fetal conditions and fatal decisions: ethical dilemmas in ultrasound screening in Vietnam

This paper situates discussion of the ethics of ethnographic research against the background of a theoretical and methodological debate about the relationship between ethics and method, and about the relationships between research methods and their objects. In particular, the paper investigates the implications of folding together the ethical and the empirical in research and argues that this requires the development of new ethico-ethnographic methods for the investigation of ethico-moral objects. The paper falls into three main parts. The first considers calls for what has come to be known as empirical ethics, that is, for a more empirically informed bioethics, by way of an exploration of the integration of ethnographic methods in bioethics, and concludes that approaches which see the ethical and the empirical as 'complementary' do not do justice to the methodological implications of enfolding the ethical and the ethnographic. The second part juxtaposes this with calls for the integration of ethics in ethnography and, similarly, argues that the enfolding of the ethical and the empirical in ethnography calls for the development of new methods. The paper goes on to problematise the 'negotiational' approaches to informed consent preferred by many ethnographers, arguing that the concept of negotiation, rather than offering a solution to the problem of consent, is itself ethically complex and in need of analysis. The paper argues that, in the context of ethnographic research, the possibility of negotiational forms of consent depends upon engagement between researchers and researched, with unavoidably 'ethical' concepts such as 'respect', 'recognition', 'dignity', 'justice' and so on, and that this poses methodological challenges to ethnography. The paper's third section explores the implications of these arguments for research practice, using The Genethics Club as an example.     

Children,Longitudinal Studies,and Informed Consent

This paper deals with ethical issues of particular relevance to longitudinal research involving children. First some general problems concerning information and lack of understanding are discussed. Thereafter focus is shifted to issues concerning information and consent procedures in studies that include young children growing up to become autonomous persons while the project still runs. Some of the questions raised are: When is it right to include children in longitudinal studies? Is an approval from the child needed? How should information to children be handled? A general point stressed is that autonomy considerations underline the importance of adjusting the information given to meet demands. A “presumption of competence” may be needed in research involving children, in order to pay their views sufficient attention.     

Randomized controlled trials in environmental health research: ethical issues

Randomized controlled trials (RCTs) are becoming increasingly common in environmental health research. Like all studies involving human subjects, environmental health RCTs raise many ethical challenges, ranging from obtaining informed consent to minimizing risks to protecting privacy and confidentiality. One of the most important issues raised by these studies is whether it is ethical to withhold effective environmental health interventions from research subjects in order to satisfy scientific objectives. Although environmental health investigators usually do not have professional obligations to provide medical care to research subjects, they have ethical obligations to avoid exploiting them. Withholding interventions from research subjects can be ethical, provided that it does not lead to exploitation of individuals or groups. To avoid exploiting individuals or groups, investigators should ensure that research subjects and study populations receive a fair share of the benefits of research.     

A model designed to enhance informed consent: experiences from the HIV prevention trials network

HIV prevention research in developing countries has resulted in increased attention to and discussion of ethical issues, particularly the issue of the quality of informed consent. We present a conceptual framework for an enhanced informed consent process, drawing on experiences garnered from domestic and international studies conducted by the HIV Prevention Trials Network, funded by the National Institutes of Health. This framework guides the development of an informed consent process designed to help ensure initial and continued comprehension of research participation, with an emphasis on HIV prevention research. Attention is focused at the individual and community levels and on 3 study phases: preenrollment, enrollment, and postenrollment.

Empty ethics: the problem with informed consent

Informed consent is increasingly heralded as an ethical panacea, a tool to counter autocratic and paternalistic medical practices. Debate about the implementation of informed consent is constricted and polarised, centering on the right of individuals to be fully informed and to freely choose versus an autocratic, paternalistic practice that negates individual choice. A bioethical framework, based on a principle-led form of reductive/deductive reasoning, dominates the current model of informed consent. Such a model tends to abstract the process of consent from its clinical and social setting. By flashing out the social process involved when patients and healthy volunteer subjects consent to take part in clinical drug trials, this paper attempts to address the problem arising from the current 'empty ethics' model. My arguments are substantiated by qualitative interview data drawn from a study I conducted on the process of consent as experienced by participants in clinical drug trials.
