The World Medical Association
Declaration of Helsinki
World Medical Association Declaration of Helsinki:
Recommendations Guiding Medical Doctors in Biomedical Research Involving
Human Subjects
Adopted by the
18th World Medical Assembly, Helsinki, Finland, 1964 and as revised by
the World Medical Assembly in Tokyo, Japan in 1975, in Venice, Italy in
1983, and in Hong Kong in 1989.
Introduction
It is the mission of the physician to safeguard
the health of the people. His or her knowledge and conscience are dedicated
to the fulfillment of this mission.
The Declaration
of Geneva of the World Medical Association binds
the physician with the words, "The health of my patient will be
my first consideration," and the International Code of Medical
Ethics declares that, "A physician shall act only in the patientÕs
interest when providing medical care which might have the effect of
weakening the physical and mental condition of the patient."
The Purpose of biomedical research involving
human subjects must be to improve diagnostic, therapeutic and prophylactic
procedures and the understanding of the aetiology and pathogenesis of disease.
In current medical practice most diagnostic,
therapeutic or prophylactic procedures involve hazards. This applies especially
to biomedical research.
Medical progress is based on research which ultimately
must rest in part on experimentation involving human subjects.
In the field of biomedical research a fundamental
distinction must be recognized between medical research in which the aim
is essentially diagnostic or therapeutic for a patient, and medical research,
the essential object of which is purely scientific and without implying direct
diagnostic or therapeutic value to the person subjected to the research.
Special caution must be exercised in the conduct
of research which may affect the environment, and the welfare of animals
used for research must be respected.
Because it is essential that the results of laboratory
experiments be applied to human beings to further scientific knowledge and
to help suffering humanity, the World Medical Association has prepared the
following recommendations as a guide to every physician in biomedical research
involving human subjects. They should be kept under review in the future.
It must be stressed that the standards as drafted are only a guide to physicians
all over the world. Physicians are not relieved from criminal, civil and
ethical responsibilities under the laws of their own countries.
I. Basic Principles
- Biomedical research involving human
subjects must conform to generally accepted scientific principles and should
be based on adequately performed laboratory and animal experimentation
and on a thorough knowledge of the scientific literature.
- The design and performance of each experimental
procedure involving human subjects should be clearly formulated in an experimental
protocol which should be transmitted for consideration, comment and guidance
to a specially appointed committee independent of the investigator and
the sponsor provided that this independent committee is in conformity with
the laws and regulations of the country in which the research experiment
is performed.
- Biomedical research involving human
subjects should be conducted only by scientifically qualified persons and
under the supervision of a clinically competent medical person. The responsibility
for the human subject must always rest with a medically qualified person
and never rest on the subject of the research, even though the subject
has given his or her consent.
- Biomedical research involving human
subjects cannot legitimately be carried out unless the importance of the
objective is in proportion to the inherent risk to the subject.
- Every biomedical research project involving
human subjects should be preceded by careful assessment of predictable
risks in comparison with foreseeable benefits to the subject or to others.
Concern for the interests of the subject must always prevail over the interests
of science and society.
- The right of the research subject to
safeguard his or her integrity must always be respected. Every precaution
should be taken to respect the privacy of the subject and to minimize the
impact of the study on the subjectÕs physical and mental integrity and
on the personality of the subject.
- Physicians should abstain from engaging
in research projects involving human subjects unless they are satisfied
that the hazards involved are believed to be predictable. Physicians should
cease any investigation if the hazards are found to outweigh the potential
benefits.
- In publication of the results of his
or her research, the physician is obliged to preserve the accuracy of the
results. Reports of experimentation not in accordance with the principles
laid down in this Declaration should not be accepted for publication.
- In any research on human beings, each
potential subject must be adequately informed of the aims, methods, anticipated
benefits and potential hazards of the study and the discomfort it may entail.
He or she should be informed that he or she is at liberty to abstain from
participation in the study and that he or she is free to withdraw his or
her consent to participation at any time. The physician should then obtain
the subjectÕs freely-given informed consent, preferably in writing.
- When obtaining informed consent for
the research project the physician should be particularly cautious if the
subject is in a dependent relationship to him or her or may consent under
duress. In that case the informed consent should be obtained by a physician
who is not engaged in the investigation and who is completely independent
of this official relationship.
- In case of legal incompetence, informed
consent should be obtained from the legal guardian in accordance with national
legislation. Where physical or mental incapacity makes it impossible to
obtain informed consent, or when the subject is a minor, permission from
the responsible relative replaces that of the subject in accordance with
national legislation. Whenever the minor child is in fact able to give
a consent, the minorÕs consent must be obtained in addition to the consent
of the minorÕs legal guardian.
- The research protocol should always
contain a statement of the ethical considerations involved and should indicate
that the principles enunciated in the present Declaration are complied
with.
II. Medical Research Combined with Professional Care (Clinical Research)
- In the treatment of the sick person,
the physician must be free to use a new diagnostic and therapeutic measure,
if in his or her judgment it offers hope of saving life, reestablishing
health or alleviating suffering.
- The potential benefits, hazards and
discomfort of a new method should be weighed against the advantages of
the best current diagnostic and therapeutic methods.
- In any medical study, every patient--including
those of a control group, if any--should be assured of the best proven
diagnostic and therapeutic method.
- The refusal of the patient to participate
in a study must never interfere with the physician-patient relationship.
- If the physician considers it essential
not to obtain informed consent, the specific reasons for this proposal
should be stated in the experimental protocol for transmission to the independent
committee (I,2).
- The physician can combine medical research
with professional care, the objective being the acquisition of new medical
knowledge, only to the extent that medical research is justified by its
potential diagnostic or therapeutic value for the patient.
III. Non-Therapeutic Biomedical Research Involving
Human Subjects (Non-Clinical Biomedical Research)
- In the purely scientific application
of medical research carried out on a human being, it is the duty of the
physician to remain the protector of the life and health of that person
on whom biomedical research is being carried out.
- The subjects should be volunteers--either
healthy persons or patients for whom the experimental design is not related
to the patientÕs illness.
- The investigator or the investigating
team should discontinue the research if in his/her or their judgment it
may, if continued, be harmful to the individual.
- In research on man, the interest of
science and society should never take precedence over considerations related
to the well-being of the subject.
