were able to consent, were not being coerced to
do the study and understood the risks and
benefit involved.

4. Informed Consent
˚ Informed consent is a key instrument in protecting
the right.
˚ Procurement of consent ensures human dignity of
the participants and also shows respect for them.
˚ Informed consent is one of the primary ethical
principles governing human subject research.

subjects will understand the nature of the research
and can knowledgeably and voluntarily decide
whether or not to participate

requires that we do not act against a person’s
wishes, and thus genuine consent to participate in

- Informed Consent is one of the 8 requirements for
clinical research.

- To determine whether participating in research fits
with their values and interests.
- To decide whether to contribute to this specific

- To protect themselves from risks.
- To decide whether they can fulfill the

9. HISTORICAL BACKGROUND OF INFORMED
CONSENT
Early References
1891- Prussian Minister of Interior , tuberculin for

against a person’s will.
1898- Dr. Albert Neisser was fined by the Royal

vaccination for Syphilis.
1907- Sir Willium Osler endorsed the necessity of
informed consent in medical research.

10. 1931- Health Department regulations of German
Reich stated that both human experimentation
and the use of novel treatment required consent
in a clear and undebatable manner.

11. World war-II and unethical clinical trials done
by US Health Services gave birth of Bio-
ethics.
Creation of IRB and notion of Informed
Consent.

12. - During World War –II
- In Nazis Concentration camp and in America
and Britain
- President F. Roosevelt-Office of Scientific
research to combat Dyscentry, Influenza,
Malaria
- Use orphan, mentally retarded, psychotic
patients
- Penicillin to prisoners to settle the dose.
- Attitude was different
- NIH- funds for experimentation, No right for
participants.

13. - 1945-1966 NIH funded 2000 research projects,
none of them use informed consent
- Thalidomide- Birth defects
- Amendment to FD and cosmetic acts.
- June 16th,1966. Henry Beecher- NEJM, describe
22 examples done on vulnerable group.
- IRB(1960)+ FDA
- Tuskegee Syphilis study 1932-1972
- 1997:President Clinton apologized

14. - (1960-1970)
- National Research Act
- National Commission for protection of
research participants in Biomedical and
Behavioral Research.
- 1979,Belmont Report

15. Belmont Report
º Expanded the definition of Informed
consent.
º Participants-kept informed throughout the
experiment,
º Understand risks and benefits.
º Protection of vulnerable group.
