Some have characterized patients living with intractable pain as a vulnerable population in both clinical and research settings. Labeling the population as vulnerable, however, does not provide clarity regarding the potential risks that they face when they participate in research. Instead, research vulnerability for patients in pain is a function of an interaction between their pain conditions and elements of the research enterprise. Therefore, the identification of potential risks requires consideration not only of characteristics of patients with chronic pain, but (...) also consideration of features of researchers, the quality of institutional oversight, and the medical/social environment within which the research is conducted. This paper provides an analysis of those risks and provides some suggestions as to how the risks might be better managed. (shrink)

The concept of vulnerability has been the topic of considerable discussion in research bioethics, largely because of dissatisfaction with early constructions of the concept that were based on subpopulations of research subjects. These subpopulations have attributes likely to undermine their capacity to provide autonomous informed consent: persons who are relatively or absolutely incapable of protecting their own interests through negotiations for informed consent. Several subpopulations were seen as requiring special protections, including children, pregnant women, prisoners, racial minorities, the economically disadvantaged, (...) the very sick, and the institutionalized. Recent years have witnessed the identification of other subpopulations with attributes that could render them vulnerable, as well. For example, the Council for the International Organization of Medical Societies has named such potentially vulnerable groups as the homeless, nursing home residents, patients with incurable diseases, patients in the emergency department, employees, students, and members of communities who are unfamiliar with modern medicine.

ABSTRACTThe concept of ‘vulnerability’ is well established within the realm of research ethics and most ethical guidelines include a section on ‘vulnerable populations’. However, the term ‘vulnerability’, used within a human research context, has received a lot of negative publicity recently and has been described as being simultaneously ‘too broad’ and ‘too narrow’.1 The aim of the paper is to explore the concept of research vulnerability by using a detailed case study – that of mineworkers in post‐apartheid South Africa. In (...) particular, the usefulness of Kipnis’s taxonomy of research vulnerability will be examined.2In recent years the volume of clinical research on human subjects in South Africa has increased significantly. The HIV and TB pandemics have contributed to this increase. These epidemics have impacted negatively on the mining industry; and mining companies have become increasingly interested in research initiatives that address these problems. This case study explores the potential research vulnerability of mineworkers in the context of the South African mining industry and examines measures that can reduce this vulnerability. (shrink)

Illicit drug users are frequently identified as a ‘vulnerable population’ requiring ‘special protection’ and ‘additional safeguards’ in research. However, without specific guidance on how to enact these special protections and safeguards, research ethics committee (REC) members sometimes fall back on untested assumptions about the ethics of illicit drug use research. In light of growing calls for ‘evidence-based research ethics’, this commentary examines three common assumptions amongst REC members about what constitutes ethical research with drug users, and whether such assumptions are (...) borne out by a growing body of empirical data. The assumptions that form the focus of this commentary are as follows: (i) drug users do not have the capacity to provide informed consent to research; (ii) it is ethically problematic to provide financial incentives to drug users to participate in research; and (iii) asking drug users about their experiences ‘re-traumatizes’ and ‘re-victimizes’ them.
