Which is an example of a situation where deferential vulnerability might be a factor?
A physician recruiting patients to be subjects In deferential vulnerability, the authority over the prospective subject is due to informal power relationships rather than formal hierarchies. The power relationship may be based on gender, race, or class inequalities, or they can be inequalities in knowledge (such as, in the doctor-patient relationship). Like institutional vulnerability, deferential vulnerability increases the risk of harm that informed consent would be compromised because it is not fully voluntary.
The NBAC looks at characteristics individuals might have that would prevent them from being able to provide voluntary informed consent. The traits may be thought of as falling into six broad areas: cognitive or communicative, institutional, deferential, medical, economic, and social. Prospective research subjects who are not able to comprehend information, deliberate, and make decisions about participation in a proposed research study have a:
Cognitive or communicative vulnerability Prospective research subjects who are not able to comprehend information, deliberate, and make decisions about participation in a proposed research study have a cognitive or communicative vulnerability.
A subject participates in a drug study because treatment is available at no or reduced cost, and he could not otherwise afford it. This is an example of:
Economic vulnerability Economic vulnerability arises when prospective subjects are disadvantaged in the distribution of social goods and services (income, housing, or healthcare). Participation in research offers the possibility of payment or attainment of healthcare or other services that are otherwise not available, and induce persons to enroll in a research study when it might be against their better judgment and when otherwise they would not do so. These inducements to enroll threaten the voluntary nature of consent and raise the danger of exploitation.
According to the authors, there are four common abuses that historically are described as giving rise to vulnerability. Which response below contains the correct four?
Physical control, coercion, undue influence, and manipulation There are four common abuses that historically are described as giving rise to vulnerability 1) physical control, 2) coercion, 3) undue influence, and 4) manipulation. These exist along a continuum of severity with physical control being the most severe and undue influence and manipulation being the least (Nelson and Merz 2002, V69-80). The other abuses- prejudice, neglect, and disrespect - should still be avoided in research.
Which is true of inducements in research?
Inducements constitute an "undue influence" if they alter a potential subject's decision-making processes, such that they do not appropriately weigh the risk-benefit relationship of the research. Inducements are offers that influence people to make decisions, or do things they would not otherwise do. Inducements and the influence they cause may be acceptable, or they may be "undue," and the distinction is not always clear or universally agreed upon. Offering $10 may be acceptable for an hour-long research study; offering $1000, or a better grade in a class, is probably not appropriate. In general, inducements constitute an "undue influence" if they alter a potential subjects decision-making processes such that they do not appropriately consider the risk-benefit relationship of the research.
Subjects with a serious illness may be at risk for exploitation because they may be desperate for a possible cure. This is an example of:
Medical vulnerability Medical vulnerability arises when prospective subjects have serious health conditions for which there are no satisfactory standard treatments. Subjects with serious health problems may not be able to adequately weigh the risks and potential benefits of the research. Subjects are at risk of exploitation because they may overestimate potential benefit. Deferential vulnerability is similar to institutional vulnerability, but the authority over the prospective subject is due to informal power relationships rather than formal hierarchies. Economic vulnerability arises when prospective subjects are disadvantaged in the distribution of social goods and services (income, housing, or healthcare). Therapeutic misconception occurs when subjects blur the roles played by physician-researchers and fail to appreciate the difference between research and treatment.
Identify the following groups that are protected in the federal regulations (45 CFR 46), specifically in Subparts B, C, and D with additional protections:
Pregnant women, prisoners, children The HHS federal regulations at 45 CFR 46 includes three subparts (B, C, and D) that specifically provide additional protections to vulnerable groups. The vulnerable groups identified are: Subpart B. Additional Protections for Pregnant Women, Human Fetuses and Neonates Involved in Research Subpart C. Additional Protections Pertaining to Biomedical and Behavioral Research Involving Prisoners as Subjects Subpart D. Additional Protections for Children Involved as Subjects in Research. The regulations do not provide specific additional protections for elderly, mentally disabled or terminally ill.
In considering NBAC's analytic approach, an otherwise competent person who is acutely ill might be considered at especially high risk of harm for:
Situational cognitive vulnerability Subjects who do not lack capacity, but are in situations that do not allow them to exercise their capacities effectively, may suffer situational cognitive vulnerability. This might occur when a subject is distracted or during an emergency situation, such as an acute illness or injury. Capacity-related cognitive vulnerability can occur when subjects to some extent lack capacity to make informed choices. Communicative vulnerability can occur when subjects do not lack capacity, but due to limited ability to communicate with the researchers are not able to exercise their capacities effectively. Economic vulnerability arises when prospective subjects are disadvantaged in the distribution of social goods and services (income, housing, or healthcare).
