But research is a good thing… why do research subjects

need “protection?”

But research is a good thing… why do research subjects

need “protection?”

Concerns for protecting subjects grew out of a long

history in which people were abused in the name of science

Celsus, 1st century AD

“It is not cruel to inflict on a few criminals sufferings which may benefit multitudes of innocent people through all centuries.”

NUREMBERG CODE1947

NUREMBERG CODE1947

• Voluntary informed consent absolutely essential• Research should yield useful results• Base research on prior work• Avoid physical and mental suffering• No expectation of death or disabling injury• Risk must be outweighed by importance• Subjects must be protected from injury• Qualified scientists, adequate facilities• Subject free to stop at any time• Investigator must be ready to withdraw subject

“Before IRBs, the only consent required was that of a researcher's department head. The Nuremberg Code was ignored in practice. As I look back on it, the interpretation of these codes was that they were necessary for barbarians, but not for fine upstanding people... In this prestigious unit we had a very strong obligation to behave in a civilized manner.”

Dr. William Silverman, Columbia pediatrician, on the postwar mentality (ACHRE interviews)

“Sometimes, with the best of intentions, scientists and public officials… working for the benefit of us all, forget that people are people. They concentrate so totally on plans and programs, experiments, statistics- on abstractions- that people become objects, symbols on paper, figures in a mathematical formula…”

Atlanta Constitution, July 27, 1972

Independent review of proposed research, to protect the rights and welfare of participants

At least 5 members, not all men, not all women (UNC IRBs have 10-25 members)

Not all members of one profession Diversity Expertise appropriate to the research At least one scientist, one non-scientist At least one member not otherwise affiliated

Current Challenges and Opportunities Current Challenges and Opportunities • Continuing legacy of Tuskegee• Storing specimens and data for future unspecified research• Genetic testing• Return of results to participants

• Research results?• Incidental findings?

• Data sharing data security• Waiver of consent• Community engagement • Study design issues

• Multisite research• “Standard of Care” research• Cluster randomized trials
