What is human subjects research part i l.jpg
What Is Human Subjects Research? – Part I

Federal definition of research

A systematic investigation, including research development, testing, and evaluation designed to develop or contribute to generalizable knowledge.


What is human subjects research part ii l.jpg
What Is Human Subjects Research? – Part II

Federal definition of human subject

A living individual about whom an investigator (professional or student) conducting research obtains

  • Data through intervention or interaction with the individual, or

  • Identifiable private information.


Slide6 l.jpg

Definitions Continued

  • Intervention includes both physical procedures by which data are gathered and manipulations of subject or subject’s environment that are performed for research purposes.

  • Interaction includes communication or interpersonal contact between investigator and subject.


Definitions continued l.jpg
Definitions Continued

  • Private information includes information about behavior that occurs in a context in which an individual can reasonably expect that no observation or recording is taking place, and information which has been provided for specific purposes by an individual and which the individual can reasonably expect will not be made public.



The nuremberg trial l.jpg
The Nuremberg Trial

  • Trial of Nazi doctors who experimented on 300 Dachau concentration camp prisoner-subjects, of whom 30% died.

  • Held from December 9, 1946 to August 20, 1947.

  • 23 defendants charged with murder, torture, and other atrocities committed in the name of medical science. 15 found guilty.


Nuremberg code 1947 l.jpg
Nuremberg Code - 1947

  • Written as part of the judgment of the Nazi trials.

  • Became the “ethical yardstick” by which the defendants had been measured and guilt determined.

  • Essential reading for everybody involved in human subject research.


Principles of nuremberg code l.jpg
Principles of Nuremberg Code

  • Voluntary informed consent is essential

  • Research should yield useful results

  • Risk must be outweighed by importance of research

  • Base research on prior animal experiments

  • Avoid physical and mental suffering


Principles of nuremberg code continued l.jpg
Principles of Nuremberg Code(continued)

  • Only qualified scientists may conduct research

  • Subjects may withdraw from study

  • Investigators must be willing to withdraw subjects

  • No expectation of death or disabling injury


Effect of nuremberg code l.jpg
Effect of Nuremberg Code

  • Code largely ignored until 1964 because researchers did not see the relevancy to their own work

    • Hippocratic oath

  • Missed a lot of important aspects of research

    • Children and informed consent

    • People with diminished mental capacity and informed consent


Declaration of helsinki 1964 l.jpg
Declaration of Helsinki - 1964

  • Rules developed by researchers and physicians

  • Reinterpretation of Nuremberg

  • Became required for publication in scientific journals to state that the research abided by the Declaration of Helsinki


Public health service policy l.jpg
Public Health Service Policy

  • 1966: All PHS supported research must undergo prior review to:

    • Protect the rights and welfare of subjects

    • Assure appropriate informed consent

    • Determine acceptable risk/benefit balance

Beginnings of the IRB

(Institutional Review Board)


Era of standards l.jpg
Era of Standards

  • Standards accepted by researchers

  • Standards accepted by the media

  • Standards became the accepted principles for judgment of research

    • Thalidomide Trial

    • Jewish Chronic Disease Study

    • Willowbrook Hepatitis Study

    • Hidden Recorder Studies

    • Milgram Study

    • Tuskegee Study


The tuskegee study l.jpg
The Tuskegee Study

  • Purpose: identify the natural history of untreated syphilis

  • Began in 1932

  • Involved 300 black males with syphilis

  • 1933 – added 300 controls

  • Was initially supposed to last 1 year

  • Study stopped in March of 1973 after government investigations and public pressure


Syphilis study problems l.jpg
Syphilis Study Problems

  • Lack of respect for persons

    • No informed consent

    • Deception

    • Coercion

  • Lack of good will to subjects

    • Withholding effective treatment (penicillin)

    • No continuing review of the research

  • Unjust

    • Used an extremely vulnerable population: illiterate, poor farmers in rural Alabama


Response to research abuses l.jpg
Response to Research Abuses

  • 1974 – Congress passes the National Research Act

    • Requirements for informed consent

    • Necessary review of research by IRB

  • May 1974 – First version of 45 CFR 46

  • April 1979 – The Belmont Report

  • 1981 – Revision of 45 CFR 46

  • 1991 – Common Rule: 56 FR 28003

  • 2001 – Latest revision of 45 CFR 46 incorporates Common Rule


The belmont principles how they came about l.jpg
The Belmont Principles: How They Came About

  • 1974 – establishment of the National Commission by the federal government

  • Task

    • “Identify basic ethical principles that underlie the conduct of human research.”

    • Develop guidelines to ensure that human research follows these principles

  • 1979 – The Belmont Report: current set of federal regulations


The belmont principles l.jpg
The Belmont Principles

  • Respect for persons

  • Beneficence

  • Justice


Respect for persons l.jpg
Respect for Persons

  • Treat individual as autonomous agents

  • Do not use people as a means to an end

  • Allow people to choose for themselves

  • Give extra protection to those with limited autonomy and have an inability to choose for themselves


Beneficence l.jpg
Beneficence

  • Do no harm

  • Prevent harm

  • Prevent evil

  • Promote good

  • Maximize possible benefits and minimize risk

    • Benefits to individual and/or to society

    • Risk: consider physical, social, legal, economic, psychological


Justice l.jpg
Justice

  • Fair sharing of burdens and benefits of research

    • Selection of subjects should not systematically draw from certain classes simply because of their easy availability

    • Inclusion of diverse populations/groups

    • Subjects should have a future chance of benefiting personally from the subsequent applications of research findings


Rules derived from principles l.jpg
Rules Derived From Principles

  • Respect for persons

    • Informed Consent

    • Respect for privacy

      • Confidentiality

      • Anonymity

  • Beneficence

    • Good research design

    • Competent investigators

    • Favorable risk/benefit analysis

  • Justice

    • Equitable selection of research subjects


Conflict in belmont principles l.jpg
Conflict in Belmont Principles

  • Conflict is expected

    • Sometimes decisions that are made utilizing the principles may yield different outcomes, depending on which principle is being considered: one decision is to approve the research, one to limit the research, one to deny the research

  • Remember: all 3 principles are on equal footing with equal moral force.

    • Consider each situation individually

    • Carefully review the principles

    • Avoid the tendency to always put one principle above another

Is any research exempt from review l.jpg
Is Any Research Exempt From Review?

Yes, if the research involves no more than minimal risk to subjects, no ethical concerns, does not involve vulnerable subjects, and meets at least one of the exempt research categories established by the government regulations. IRB chair can make this determination.


Expedited review l.jpg
ExpeditedReview

  • Nine governmentally designated research categories that allow for expedited review

  • Proposal distributed to all IRB members and all must agree on expedited review
