Privacy (respect and protection) Nurses Duties to Safety ANA Code of Ethics 1.5 Nurses value the distinctive contribution of individuals or groups as they seek to achieve safe, quality patient outcomes in all settings. 3.4 Nurses must participate in the development, implementation, and review of and adherence to policies that promote patient health and safety, reduce errors and waste, and establish and sustain a culture of safety. 3.5 Nurses must be alert to and must take appropriate action in all instances of incompetent, unethical, illegal, or impaired practice or actions that place the rights or best interests of the patient in jeopardyWhen incompetent, unethical, illegal, or impaired practice is not corrected and continues to jeopardize patient well-being and
safety, nurses must report the problem 5.4 Nurses are obligated to provide for patient safety Safety Duties in Research Specified Identify risks and potential risks Design interventions to mitigate risks Screen during the study for adverse events and prepare to stop it if needed Source: Adams, Lizbeth and Timothy Callahan.

Ascertain Higher Risks Vulnerability Types of vulnerability: Cognitive Is not only degrees of immaturity, dementia, mental illness, and so on, but educational deficits, unfamiliarity with the language, and accelerated timeframes. Juridic Is some type of relegation to the power of another, and it
includes children, students, prisoners, soldiers, and others. Deferential Portrays circumstantial relegation to the influence of another, often a certain other person, and participants or candidates may have juridic vulnerability (e.g., children not wanting to argue with a parent) or not (e.g., in some cultures, women defer to men).

Ascertain Higher Risks Vulnerability Types of vulnerability, continued: Medical Describes a participant or candidate with a serious healthrelated condition for which there are no satisfactory remedies, such as end-stage AIDS or cancer, causing the person to take risks she or he usually would not. Allocational Persons require basic needs or goods such as money,
shelter, or health care, which should prompt evaluation, albeit difficult, of exploitation. Infrastructural Is not having available the protections and resources that contribute importantly to the safety of the research subject, such as a computer with (high-speed) internet access, a refrigerator, or even consistent electricity.

Ascertain Higher Risks Vulnerability Are potential participants vulnerable in the same ways? Is there nuance to vulnerability? How do we respond to the potential inclusion, or not, of vulnerable groups? What should we do? Are there consequences of not including vulnerable persons
in research? If so, what are they? Ascertain Higher Risks Vulnerability Be aware but go beyond the baseline, articulated in documents such as: 1. The Belmont Report names some vulnerable populations, available at http://www.hhs.gov/ohrp/humansubjects/guidance/belmont.html 2. Federal Regulations on the Protection of Human Subjects (45 CFR 46) regulations about some vulnerable populations, available at http://www.hhs.gov/ohrp/policy/ohrpregulations.pdf 3.

Identify Risks Conflicts-of-Interest Different types of conflicts-of-interest exist: A. Primary For clinicians in research, they are patients health and research integrity for current and future participants. B. Secondary Conflicts are around personal wellbeing, when these interests manipulate decisions around primary interests. C. Financial A researcher (potentially) receives a monetary benefit, especially for particular enrollment (per capita or finders fees) or results. D. Non-financial A researcher (potentially) gains other benefits from research, such as prestige, career advancement, or other creature comforts. Source: Goldner, Jesse. (2000).

Identify Risks Conflicts-of-Interest Different types of conflicts-of-interest exist: E. Individual A researcher has a study where she or he (potentially) receives benefit. F. Institutional (Organizational) Organizations, often academic medical centers, find themselves caught between the polarities of wanting to improve clinical care and financially benefiting from research and its sponsorship.

Journal of Law, Medicine, and Ethics, 28(4): 381-385. Arguably, the goal of universities is to seek the truth while the goal of (pharmaceutical) companies is to make money.

Identify Risks Conflicts-of-Interest What is the difference between actual and potential (perceptual) conflicts-of-interest? Do both actual and potential conflicts-of-interest deserve attention? Why? What may result from potential (perceptual) conflicts-of-interest? Could actual or potential conflicts-of-interest compromise patient safety? How?

Screen for Adverse Events Ability to Respond Does the timing for study enrollment matter? Consider the following examples: TGN1412 Is a genetically engineered anti-CD28 antibody used to expand T cells, possibly having therapeutic benefit for those with autoimmune conditions such as rheumatoid arthritis. Animal studies did not raise concerns and established dosing for phase I clinical trials with human subjects. However, a TGN1412 infusion, 500x smaller than animal doses, caused a life-threatening cytokine storm and multiple organ system failure in the first six, healthy, human volunteers. All six participants received TGN1412 within 90 min. of one another, such that the first volunteer experienced symptoms as the last was being infused.
Screen for Adverse Events Ability to Respond TriA (triacetylolandomycin) Evidences hepatic dysfunction, yet a dosing study proceeded with 50 participants (healthy 13- to 39-year-olds, including those with cognitive disabilities, incarcerated youths). Within two weeks, 54 percent had abnormal excretion of bromsulfalein and 8 patients had marked dysfunction with biopsies confirming liver damage. Source: Beecher, Henry. (2001).

Mitigating Adverse Events Potential Options
There are at least three potential ways to proactively help participants safety by eliminating or mitigating adverse effects Does Not Help Safety Mitigating Adverse Events TGN1412 Responses There was plenty of
Monday-morning quarter-backing for the TGN1412 study even though it is too late for a course correction Does Not Help Safety Careful Informed Consent Considerations What are the ethical elements necessary for appropriate informed consent? Careful Informed Consent Considerations
What to avoid: Being nebulous about possible benefits Misrepresenting treatment, making research seem like treatment Shifting and unclear terms Source: King, Nancy et al. (2005). Consent forms and the therapeutic misconception. IRB Ethics & Human Research, 27(1): 6. Conceptualizing informed consent as an event rather than a process Concentrating on the consent form itself Source: Berg, JW, Appelbaum, Paul at al. (2001). Informed Consent: Legal Theory and Clinical Practice. New York, NY: Oxford University Press, 295. Industry terms, medical jargon, technobabble
Careful Informed Consent Considerations What to do or consider: If possible, slow down the assimilation of new information: ask questions after review of the written documents, provide further info, schedule follow-up Balance clarity with brevity in the document; reading level Discussion groups with participants who have gone through the research Questionnaires to assess knowledge and comprehension before consent Differentiate research from clinical care, being specific about dissimilarities Source: Berg, JW, Appelbaum, Paul at al. (2001). Informed Consent: Legal Theory and Clinical Practice. New York, NY: Oxford University Press, 291-299.

and best data: Consent to research and the therapeutic misconception. Hastings Center Report, 17(2): 24. Careful Informed Consent Considerations What to do or consider, continued: Who discusses informed consent? Depending on the study, 47-70% have a principal investigator involved in informed consent, with many delegating it to assistants. Does this show investigators do not hold consent in high regard? What are the understandings of the assistants? What standards are they held to, meaning are there expectations of enrolling a certain number of participants? To what extent to principal investigators monitor assistants? Source: Berg, JW, Appelbaum, Paul at al. (2001). Informed Consent: Legal Theory and Clinical Practice.

Other Responsibilities Ancillary care Is [an understanding] which goes beyond the requirements of scientific validity, safety, keeping promises, or rectifying injuries.

The ancillary-care responsibilities of medical researchers: An ethical framework for thinking about the clinical care that researchers owe their subjects. Hastings Center Report, 34(1): 26. Rollout care Is a subset of ancillary care related to the types of care needed, if any, for participants after the conclusion of the study. Sample storage and banking Is the treatment of human samples (e.g., tissue, DNA), not just during, but after the conclusion of a study
The Immortal Life of Henrietta Lacks by Rebecca Skloot Other Responsibilities The scholarly community does not have agreement about obligations for ancillary and rollout care. The graph below represents the tensions between views. Pure clinical research Pure How would you describe the differences between above views? Some propose a framework for what qualifies for research support and what does not.

while asking participants to give up all rights? Community and Populations A few words about understanding culture An ethnographic study of Vietnamese Americans in Orange County, CA found factors associated with adherence (compliance) with a TB treatment. Medicines associated with feeling imbalanced or incongruent, feeling hot, the influence of advocates (family, friends), and community perception all influenced adherence in this community. Ito, Karen. (1999). Health culture and the clinical encounter: Vietnamese refugees responses to preventive drug treatment of inactive tuberculosis. Medical Anthropology Quarterly, 13(3): 338364. Situation: How could this study impact research on a new TB treatment with a similar chemical properties and pathways within the same community?
Community and Populations Consulting with a community group has several purposes: A. It is a bridge between researchers and the population being investigated B. Communicate any community or cultural concerns C. Aid the creation of study-related resources D. Support vulnerable groups and their rights; help groups with stigma E. Provide suggestions for participants study enrollment F. Develop trust through open communication G. Look for indications about harm to the community Quinn, Sandra. (2004).
