˚ Informed consent is a process which is designed

˚ Voluntary consent means that the participants
were able to consent, were not being coerced to
do the study and understood the risks and
benefit involved.

˚ 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.
˚ Informed consent assures that prospective research
subjects will understand the nature of the research
and can knowledgeably and voluntarily decide
whether or not to participate
Informed Consent

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

HISTORICAL BACKGROUND OF INFORMED
CONSENT
Early References
1891- Prussian Minister of Interior , tuberculin for
the treatment of tuberculosis must not be used

1898- Dr. Albert Neisser was fined by the Royal

1907- Sir Willium Osler endorsed the necessity of
informed consent in medical research.
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.
World war-II and unethical clinical trials done
by US Health Services gave birth of Bioethics.

- During World War –II
- In Nazis Concentration camp and in America
and Britain
- President F. Roosevelt-Office of Scientific
research to combat Dyscentry, Influenza,

patients
- Penicillin to prisoners to settle the dose.
- Attitude was different
- NIH- funds for experimentation, No right for
participants.
- 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

- IRB(1960)+ FDA
- Tuskegee Syphilis study 1932-1972
- 1997:President Clinton apologized
-
(1960-1970)
