Communication and Miscommunication in Informed Consent to Research

Biomedical ethics require that research subjects be aware that the drugs they take or procedures they undergo are designed to fulfill the conditions of the experiment and not to benefit a subject’s health. This apparently straightforward distinction between research and treatment is a source of much controversy and misunderstanding. Ethicists have labeled this problem the therapeutic misconception. This misconception and, more broadly, informed consent have been studied extensively. Nonetheless, the therapeutic misconception persists among research subjects. This paper argues that one factor overlooked in the persistence of the therapeutic misconception is the effect of the theoretical paradigm that guides the practice and analysis of informed consent. The paradigm poses an idealized model of communication that ignores social context. This paper examines informed consent practices associated with a cancer research trial to demonstrate an alternative approach to studying informed consent to research. Through analysis of informed consent session transcripts, it demonstrates the importance of taking account of not only what is said, but how and by whom it is said

State Power and Record-Keeping: the History of Individualized Surveillance in the United States, 1790-1935

This dissertation charts the emergence of individualized record-keeping in the United States by tracing the history of criminal identification records and the invention of statistically-based identification systems, which the state applied to the population in general. The dissertation ties the invention of these individualized record-keeping systems to the development of a state surveillance capacity and its need for fixed, official identities. The dissertation situates this investigation in the history of writing and argues that to understand the roots of writing\u27s power in contemporary society, essentialist assertions about writing\u27s utility and superiority must be replaced with investigations of how writing was transformed into a critical source of state power. Of particular interest here is how the construction of centralized, state-administered records extended and elevated the state\u27s organizational memory. The dissertation starts with a detailed examination of the earliest US reform prison where the link between individual identities and state surveillance was first forged. It continues with an analysis of the emergence of state identification practices from local into national arenas that focuses on the appearance of practices associated with preventive policing in the mid-1800s. The dissertation then describes the invention and application of statistically-based identification methods, including criminal anthropometry and fingerprinting. These statistical methods could be applied reliably to large populations and thus allowed the state to expand its identification interests beyond criminals to the population at large. The dissertation closes with a description of the construction of the US national fingerprint system. In describing each of these phases, the dissertation analyzes both the motives which inspired proponents of improved identification systems and the actions they took to invent, refine, and deploy new methods to serve those motives. This analysis locates the power of writing in complex record-keeping practices, usually invisible because so commonplace, and re-casts state record-keeping systems from by-products of pragmatic bureaucratic activity into intentionally created, carefully fostered reservoirs of state power

Research Issues in Genetic Testing of Adolescents for Obesity

Obesity is often established in adolescence, and advances are being made in identifying its genetic underpinnings. We examine issues related to the eventual likelihood of genetic tests for obesity targeted to adolescents: family involvement; comprehension of the test’s meaning; how knowledge of genetic status may affect psychological adaptation; minors’ ability to control events; parental/child autonomy; ability to make informed medical decisions; self-esteem; unclear distinctions between early/late onset for this condition; and social stigmatization. The public health arena will be important in educating families about possible future genetic tests for obesity

\u27Iceland Inc.\u27?: On the ethics of commercial population genomics

A detailed analysis of the Icelandic commercial population-wide genomics database project of deCODE Genetics was performed for the purpose of providing ethics insights into public/private efforts to develop genetic databases. This analysis examines the moral differences between the general case of governmental collection of medical data for public health purposes and the centralized collection planned in Iceland. Both the process of developing the database and its design vary in significant ways from typical government data collection and analysis activities. Because of these differences, the database may serve the interests of deCODE more than it serves the interests of the public, undermining the claim that presumed consent for this data collection and its proprietary use is ethical. We believe that there is an evolving consensus that informed consent of participants must be secured for population-based genetics databases and research. The Iceland model provides an informative counterexample that holds key ethics lessons for similar ventures

Pilot Study: Does the White Coat Influence Research Participation?

In health care, the white coat symbolizes professionalism, trustworthiness, and competence; it also represents power. This suggests that the wearing of a white coat could influence the decisions of potential subjects who are asked to participate in clinic-based research

Older Adults’ Attitudes Toward Enrollment of Noncompetent Subjects Participating in Alzheimer’s Research

OBJECTIVE: Research that seeks to enroll noncompetent patients with Alzheimer’s disease without presenting any potential benefit to participants is the source of substantial ethical controversy. The authors used hypothetical Alzheimer’s disease studies that included either a blood draw or a blood draw and lumbar puncture to explore older persons’ attitudes on this question. METHOD: Face-to-face interviews were conducted with 538 persons age 65 and older. Questions explored participants’ understanding of research concepts, their views on enrolling persons with Alzheimer’s disease in research, and their preferences regarding having a proxy decision maker, granting advance consent, and granting their proxy leeway to override the participant’s decision. Additional questions assessed altruism, trust, value for research, and perceptions of Alzheimer’s disease. RESULTS: The majority (83%) were willing to grant advance consent to a blood draw study, and nearly half (48%) to a blood draw plus lumbar puncture study. Most (96%) were willing to identify a proxy for research decision making, and most were willing to grant their proxy leeway over their advance consent: 81% for the blood draw study and 70% for the blood draw plus lumbar puncture study. Combining the preferences for advance consent and leeway, the proportion who would permit being enrolled in the blood draw and lumbar puncture studies, respectively, were 92% and 75%. Multivariate models showed that willingness to be enrolled in research was most strongly associated with a favorable attitude toward biomedical research. CONCLUSIONS: Older adults generally support enrolling noncompetent persons with Alzheimer’s disease into research that does not present a benefit to subjects. Willingness to grant their proxy leeway over advance consent and a favorable attitude about biomedical research substantially explain this willingness

Reflections on the Cost of Low-Cost Whole Genome Sequencing: Framing the Health Policy Debate

The cost of whole genome sequencing is dropping rapidly. There has been a great deal of enthusiasm about the potential for this technological advance to transform clinical care. Given the interest and significant investment in genomics, this seems an ideal time to consider what the evidence tells us about potential benefits and harms, particularly in the context of health care policy. The scale and pace of adoption of this powerful new technology should be driven by clinical need, clinical evidence, and a commitment to put patients at the centre of health care policy

Development of a process to disclose amyloid imaging results to cognitively normal older adult research participants

Introduction: The objective of this study was to develop a process to maximize the safety and effectiveness of disclosing Positron Emission Tomography (PET) amyloid imaging results to cognitively normal older adults participating in Alzheimer’s disease secondary prevention studies such as the Anti-Amyloid Treatment in Asymptomatic Alzheimer’s Disease (A4) Study. Methods: Using a modified Delphi Method to develop consensus on best practices, we gathered and analyzed data over three rounds from experts in two relevant fields: informed consent for genetic testing or human amyloid imaging. Results: Experts reached consensus on (1) text for a brochure that describes amyloid imaging to a person who is considering whether to undergo such imaging in the context of a clinical trial, and (2) a process for amyloid PET result disclosure within such trials. Recommendations included: During consent, potential participants should complete an educational session, where they receive verbal and written information covering what is known and unknown about amyloid imaging, including possible results and their meaning, implications of results for risk of future cognitive decline, and information about Alzheimer’s and risk factors. Participants should be screened for anxiety and depression to determine suitability to receive amyloid imaging information. The person conducting the sessions should check comprehension and be skilled in communication and recognizing distress. Imaging should occur on a separate day from consent, and disclosure on a separate day from imaging. Disclosure should occur in person, with time for questions. At disclosure, investigators should assess mood and willingness to receive results, and provide a written results report. Telephone follow-up within a few days should assess the impact of disclosure, and periodic scheduled assessments of depression and anxiety, with additional monitoring and follow-up for participants showing distress, should be performed. Conclusions: We developed a document for use with potential study participants to describe the process of amyloid imaging and the implications of amyloid imaging results; and a disclosure process with attention to ongoing monitoring of both mood and safety to receive this information. This document and process will be used in the A4 Study and can be adapted for other research settings
