  3. The objectives of this session Workshop 2012 • Appreciate the historical context of research ethics • Understand the basics for international standards for research ethics • Identify concerns regarding risk • Describe the differences that exist when vulnerable populations are participants. • Define “Conflict of Interest” and describe some guiding principles

  4. What can we learn from the past ? • The history of politics, medicine, and business are rich and detailed. • The history of Ethics is brief and short! MEDICINE Workshop 2012

  5. A Brief History of Human Research Ethics: Workshop 2012 Nuremberg Code (1947) As part of the verdict in the Nuremberg War Crimes Trials of 23 German doctors, the Court enumerated some rules for “Permissible Medical Experiments”, now know as the “Nuremberg Code”: • voluntary consent • benefits outweigh risks • ability of the subject to terminate participation

  6. A Brief History of Human Research Ethics: Workshop 2012 Declaration of Helsinki 1964… 2000 Recommendation guiding doctors in Biomedical Research involving human subjects. “Concern for the interests of the subject must always prevail over the interests of science and society”

  7. What have we learned ? Workshop 2012 The Nuremberg Code prohibited most research involving children and many vulnerable populations. The Declaration of Helsinki formally disallowed non-therapeutic research on non-consenting subjects. The codes present difficulties for those who want to advance the health of vulnerable people, including children, and some adults who do not have the capacity for consent.

  8. A Brief History of Human Research Ethics: Workshop 2012 Tuskegee incident In 1972 it was revealed that for 40 years the US Public Health Service had been performing studies on poor black men from Tuskegee, Alabama who had been denied treatment for syphilis without ever consenting. Awareness of these studies created a scandal and demand for more stringent regulations regarding informed and voluntary participation in human research.

  9. A Brief History of Human Research Ethics: Workshop 2012 Belmont Report (1979). Special consideration needed for our primary duty to protect from harm. Regulatory frameworks have been developed to identify acceptable and unacceptable risks in research. • Requires research ethics committees to determine the balance of harms and benefits.

  10. The unexpected outcome ! Workshop 2012 Policy that strictly prohibits children and other vulnerable populations from participation in research may harm both individuals and the populations en masse by making them research “orphans.” Overprotection can harm the ones you are trying to protect!

  11. Overcoming the dilemma • Ethics committees must examine studies for acceptable balance of risk and benefit. • Principle of justice for a vulnerable and other populations means risk is distributed equally and benfits are accessible to everyone. An ever-present tension for clinicians Workshop 2012

  12. Three Principles of Research Ethics Workshop 2012 Principles: • respect for persons, • beneficence and • justice. The concept of non-malificence is complementary to beneficence: • to do good and no harm, • to maximize potential benefits, • while minimizing risk.

  13. Concept of Minimal Risk Workshop 2012 The US Federal Common Rule describes minimal risk as meaning that “the probability and magnitude of harm or discomfort anticipated in the research are not greater in and of themselves than those ordinarily encountered in daily life.”

  14. Equipoise, Risk and Therapeutic Procedures Workshop 2012 • Equipoise “a state of uncertainty as to the relative superiority of two treatments”. • Exposure to therapeutic risk may sometimes be acceptable if clinical equipoise exists. • Children may be exposed to risk if there is equipoise: treatment A vs B. • This is the case in children with cancer in which death, secondary to toxicity of treatment, is a potential event with either.

  15. Placebo Interventions Workshop 2012 A placebo should only be allowed if there are valid reasons to use it rather than an active drug. A placebo must satisfy these conditions: minimal risk, more than minimal risk but a direct benefit from the placebo a minor increase over minimal risk but the study is likely to produce knowledge of vital importance to the subject’s own disease.

  16. Conflict of Interest and Integrity in Research Workshop 2012 One of the best definitions of conflict of interest was proposed by Denis Thompson. "a conflict of interest is a set of conditions in which professional judgment concerning a primary interest (such as a patient's welfare or the validity of research) tends to be unduly influenced by a secondary interest (such as financial gain)" NEJM, 1993.

  17. Conflicts of Interest Workshop 2012 • COI for a clinician may occur if financial or personal interests may affect decision: Q: What might a person who has financial interests tied to outcome be tempted to do? • Clinicians must always give unbiased results Google images

  18. Specific Conflicts of Interest (COI) Workshop 2012 Role Confusion: Caregiver vs. Researcher • Clinicians doing research, have two goals, • to provide best care for the patient, • to acquire generalizable knowledge. • The two goals can present a conflict. • To be ethical, clinicians can’t disadvantage research subjects, particularly when they are patients who come to them for care.

  19. Remuneration for Enrolling Patients in Research Trials Workshop 2012 Finder’s fees, ie payment for recruiting or enrolling patients in research, is a COI for a clinician. • The AMA’s Council on Ethical Affairs has stated that payment by or to a clinician solely for the referral of a patient is unethical.

  20. Authorship Conflicts Workshop 2012 Each author must participate sufficiently to take responsibility for all or part of the work. Requires: a meaningful contribution to the conception and design, or acquisition of data, or analysis and interpretation of data; drafting the article or revising it critically for important intellectual content; and approval of the final version of the manuscript.

  21. Have the objectives been met? Workshop 2012 • Appreciate the historical context of research ethics • Understand the basis for international standards for research ethics • Identify concerns regarding risk • Describe the differences that exist when vulnerable populations are participants. • Understand the principles of Conflict of Interest
