  • CIOMS/Int ethics guidelines addressing ethics and conduct of research in developing countries, cultural differences, subject recruitment, informed consent, and external review
  • In 1999, 18 percent of community hospital beds in the United States had religious sponsors, of which almost 70 percent were Catholic: religious institutions provided the inpatient care for more than 5.3 million people. Furthermore, 48 (or 8 percent) of these religiously sponsored hospitals are the sole providers of hospital care in their regions.

  • Ethical Issues in Human Subjects Research Judy Stone, MD
  • The first step in the evolution of ethics is a sense of solidarity with other human eings. — Albert Sweiter

    • 1993 NIH Revitalization Act mandating inclusion of women and minorities in research
    • 1993 NIH Office of Research on Women’s Health
  • Milestones in Ethical Development
    • 1997 Food and Drug Modernization Act (FDAMA) requiring the FDA, NIH, and pharmaceutical industry to develop guidance on the inclusion of women and minorities in trials
    • 1998 Pediatric Rule passed by Congress, stipulating that new drugs for children must include specific pediatric labeling information
    • 2000 Further publicized ethical abuses prompting establishment of the Office of Human Research Protections (OHRP)
  • Belmont Report
    • National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research
    • 3 basic principles for research
  • Belmont Report
    • Respect for persons , or an individual’s autonomy-
    • elements of the informed consent requiring that:
    • Information necessary to make a decision must be presented that is,the risks and benefits, if any, of participation.
    • The information must be presented at a level that can be understood by the patient or study subject.
    • Participation must be voluntary.
  • Belmont Report
    • Benificience, or benefit to the participant
    • Who decides whether there is benefit?
  • Belmont-Beneficence
    • Loss of substantial benefits that might be gained from research
    • Paternalism
    • Pregnancy
    • Life-threatening illness (AIDS/Cancer)
  • Belmont-Justice
    • Risks and benefits should be equitably distributed among different populations
      • “ Do onto others…” rather than taking advantage of
    • Vulnerable populations
  • Vulnerable Populations
    • Military
      • 1944-1979: radiation, chemical,
        • Mustard gas, lewisite
        • Venezuelan equine encephalitis virus and the nerve
        • gas agent VX
        • Operation Whitecoat (tularemia, anthrax, Q fever)
        • 1994 Congressional review: the Department of Defense
        • “ has demonstrated a pattern of misrepresenting the danger of various military exposures that continues today”
  • Vulnerable Populations
    • Unsuspecting civilians
      • Radiation experiments: atomic weapons testing in
        • South Pacific
        • Oak Ridge
        • Los Alamos
        • Hanford, Washington
        • Plutoniaum injections (ACHRE report)
  • Vulnerable Populations What studies are being done now under the guise of counter terrorism, hidden from the public by the “Patriot Act?”
  • Vulnerable Populations-Children
    • Pint-size people vs. real data
    • 10 drugs most commonly prescribed for children that lacked pediatric labeling—drugs were prescribed more than 5 million times
    • HIV studies in foster children
      • Too vulnerable? vs denying access to potentially life-saving drugs
      • (all HIV + kids were being offered the trials)
  • Vulnerable Populations-Women
    • Pregnancy
      • Paternalism
      • Woman vs Fetus
  • Daily Ethical Encounters
    • Participants who are vulnerable from:
    • Abuse from Doctor-patient relationship
    • “ whatever you say, doc” syndrome
    • Indigent patients
  • Daily Ethical Encounters
    • Financial Pressures and Conflict of Interest
      • Financial
        • Income for Department
        • Bonuses
        • Structure of grant (pay per visit or end-loaded)
        • Pay for screening
        • Pay for quality of data, rather than # of patients
        • Avoid disincentives for dropping a patient (e.g., due to adverse reaction
      • Pressure re prestiege, publication, tenure
  • Other Conflicts of Interest at the Site
      • Use of a class of drug in a study-e.g., Quinolones, that you might not use otherwise
      • Access to care for indigent patients
      • Access to novel drug (pt may lie)
      • Adverse event classification
  • Yet more COI
    • IRB related
      • Voluntary, unpaid
      • Lack of training
      • Paid by drug company
      • Pressure from administration
      • Personal competition/conflict
  • Mrs. G?
  • Evaluating a Study
    • Does the study ask an important/valuable question?
    • Is the study design reasonable?
    • Would I be willing to be in this trial?
  • Evaluating a Potential Volunteer
    • Level of understanding based on
      • Education, life experience
    • Motivation
    • Financial need
      • vs. ethics of lack of universal health care
      • What will happen to the pt when the study ends?
    • Stage of illness
      • Risk vs. Benefit
      • What do they have to lose?
    • Would I take this drug or give it to my family member?
  • Politics of Research: Women
    • Viewed as vulnerable population
    • Paternalism
    • Woman vs. fetus
      • e.g. AIDs clinical trials
    • Religion
      • Exclusion of women from participation due to restrictions about contraceptive use
  • Politics of Research: Race
    • one-fourth of the U.S. population is made up of “people of color”
      • Only 5% of trial participants
    • Legacy of distrust
      • Tuskeegee
      • HIV-foster children study (despite evidence)
      • Nigerian Pfizer meningitis trial => resistance to polio vacciination
  • Politics of Research: Race and Gender Overlap
    • 1980 and 1983, fully one-fifth of contraceptive research was conducted in developing countries
    • Oral contraceptive research in Puerto Rico
      • Adverse events analysis was inadequate
    • Quinacrine
      • The effect of power inequities between men and women
      • Lack of social support for many women
      • Coercion by medical providers or government agencies
  • Quinacrine-Belmont Principles
    • Beneficence
      • No safety or toxicity studies of intrauterine installation
    • Distributive Justice
      • Almost all the women were low income, poorly educated women of color in developing countries.
    • Respect for Persons, autonomy, self-determination
      • No explanation of experimental nature of quinacrine and no informed consent or offer of alternatives
  • Shifting Research to Developing Countries
    • United States accounts for ~ 4 percent of the world’s population vs. 84% for dev. Countries
    • 90 percent of $ is spent on the illnesses of the wealthiest countries,
    • leaving 10 % of monies to care for 84 % of the global population
  • Vulnerable international populations
    • • Limited economic development
    • • Inadequate protection of human rights
    • • Inadequate community and cultural experience with, or understanding of, scientific research
    • • Limited availability of healthcare and treatment options
    • • Limited ability of individuals in the community to provide informed consent due to illiteracy and language, educational, or cultural barriers
  • Vulnerable international populations What standards should apply?
    • Meningitis trial
    • Maternal-fetal HIV transmission trials
    • Absolute standard of care vs. local standard?
    • What if the local standard is to do nothing?
    • International consensus is that it is ethical if:
    • it is based on a valid scientific purpose for using a lesser standard, provides social benefits for the local host community, and shows a favorable risk-benefit ratio for the individual research participants
  • Vulnerable international populations
    • Distributive justice is violated
    • the local study populations will not significantly benefit from the research if the new therapies will not be affordable to them, although they are taking a higher proportion of the risk.
