Wittgenstein, in his famous critique of philosophy, noted that the influence of an idea can be such that it alters the way that we see the world. “It is like a pair of glasses on our nose through which we see whatever we look at,” he said. “It never occurs to us to take them off.” This view of the power of an idea suggests that the interpretation of an event, and what response this event calls for, can depend upon (...) the view one has of the world. A person who is naive about medical facts may, for example, interpret chest pain upon exertion as a sign that he is “overdoing it”; were he more medically knowledgeable, the same symptom might be interpreted as a possible indicator of coronary artery disease. The naive interpretation calls for rest; the informed interpretation calls for medical attention as well. (shrink)

This is a study involving three HIV clinics in the Canadian provinces of Newfoundland and Labrador, and Manitoba. We sought to identify ethical issues involving health care providers and clinic clients in these settings, and to gain an understanding of how different ethical issues are managed by these groups. We used an institutional ethnographic method to investigate ethical issues in HIV clinics. Our researcher conducted in-depth semi-structured interviews, compiled participant observation notes, and studied health records in order to document ethical (...) issues in the clinics, and to understand how health care providers and clinic clients manage and resolve these issues. We found that health care providers and clinic clients have developed work processes for managing ethical issues of various types: conflicts between client-autonomy and public health priorities, difficulties associated with the criminalization of nondisclosure of HIV positive status, challenges with non-adherence to HIV treatment, the protection of confidentiality, barriers to treatment access, and negative social determinants of health and well-being. Some ethical issues resulted from structural disadvantages experienced by clinic clients. The most striking findings in our study were the negative social determinants of health and well-being experienced by some clinic clients – such as experiences of violence and trauma, poverty, racism, colonization, homelessness, and other factors affecting well-being such as problematic substance use. These negative determinants were at the root of other ethical issues, and are themselves of ethical concern. (shrink)

Procedures for the selection of subjects for participation in randomized clinical trials--usually formalized as eligibility criteria in the study protocol--have both scientific and ethical implications. In this thesis, I undertake an examination of eligibility criteria at three stages in the genesis and dissemination of medical knowledge: clinical trial protocol, interpretation by investigators, and reporting of study results.In the first chapter, ethical issues in subject selection are reviewed and the main study questions are presented. In the second chapter, the results of (...) an examination of eligibility criteria in two sets of clinical trials, one sponsored by the NSABP, the other sponsored by POG, covering a twenty-year time span are presented. The POG trials had far fewer eligibility criteria than the NSABP studies, suggesting that large numbers of criteria may not be necessary for high quality research. In the third chapter, the impact of subjective eligibility criteria on enrollment and investigator uncertainty is explored. Subjective criteria were associated with more variable enrollment decisions and greater uncertainty. Such criteria represent a threat to the validity, conduct and interpretation of trials and, therefore, should only be included when carefully justified. The fourth chapter examines the accuracy of the reporting of eligibility criteria in sets of corresponding study protocol, methods paper, journal article, and Clinical Alert. Important information is lost at each step in the dissemination of study results. Unnecessary criteria ought to be dropped at a trial's inception; all other criteria must be reported faithfully. The fifth chapter attempts to provide a comprehensive philosophical account of just selection procedures for clinical research using the political philosophy of Michael Walzer. The sixth, and last, chapter, discusses explanatory and pragmatic approaches to clinical trial design, overlapping scientific and ethical concerns related to eligibility criteria, and questions for further study.
