REGULATIONS
The regulations
set forth in this manual are based on the Belmont Report from the National
Commission for the Protection of Human Subjects of Biomedical and Behavioral
Research, and the Code of Federal Regulations, Title 45 - Public Welfare,
Part 46 - Protection of Human Subjects. The Belmont Report is a statement
of general ethical principles that is meant to act as a guide in resolving
ethical problems that surround the conduct of research with human subjects.
The Belmont Report is concerned with the ethics of research, while Part
46 of Title 45 of the Code of Federal Regulations (which is based on the
Belmont Report) addresses more specifically the recommended guidelines
for the protection of human subjects.
CODE
OF FEDERAL REGULATIONS
The federal
regulations are disseminated by the Office for Protection from Research
Risks (OPRR), an administrative unit within the Department of Health and
Human Services, of the National Institutes of Health. The regulations
apply to all research involving human subjects and provide definitions
for the terms research and human subject. The regulations define
research as a systematic investigation designed to develop or contribute
to generalizable knowledge. Human subject is defined as a living
individual about whom an investigator conducting research obtains data
through intervention or interaction with the individual, or identifiable
private information.
The federal
regulations describe four basic requirements for the conduct of an IRB:
(a) a statement of principles, (b) designation of one or more IRBS, (c)
appointment of IRB members, and (d) written procedures for the IRB. It
is within these parameters that the Daemen College HSRRC operates.
THE
BELMONT REPORT
The Belmont
Report was developed by the National Commission for the Protection of
Human Subjects of Biomedical and Behavioral Research in 1979. This commission
was created when the National Research Act (PL 93-348) was passed in 1974.
The Belmont Report summarizes the general ethical principles identified
by the Commission that should underlie the conduct of biomedical and behavioral
research involving human subjects.
In carrying
out its mission, the Commission considered the boundaries between biomedical/behavioral
research and the accepted routine practice of medicine, the role of the
assessment of the risk and benefit balance in determining whether humans
should be used in the research, guidelines for the selection of human
subjects, and the nature and definition of informed consent.
Since
research and practice often occur together, it is necessary to distinguish
between these two terms in order to know what activities ought to be reviewed
for the protection of human subjects. The term practice is used
to mean a commonly accepted intervention or procedure which is designed
to enhance the well-being of an individual or client and is considered
by the practicing community to have a reasonable expectation of success.
Research is used to mean an activity designed to test a hypothesis
or answer research questions, so that conclusions may be drawn and contributions
to the general knowledge of a field may be made. While research and therapy
or research and education may be carried out together, for example, when
evaluating the safety and efficacy of a therapy or of an educational strategy,
this need not cause confusion regarding whether the activity requires
review by the IRB. The general rule is that if there is an element of
research in any activity involving human subjects, the activity should
be reviewed.
The following
summary identifies the boundaries between medical/behavioral research
and the practice of medicine, and the three basic ethical principles which,
when practically applied, lead to informed consent, assessment of risk
and benefits, and the selection of subjects. The three principles identified
by the Commission as- generally accepted in our cultural tradition are
labeled: (a) respect for persons, (b) beneficence, and (c) justice. These
principles are stated in a sufficiently general manner to allow scientists,
subjects, reviewers, and informed citizens to understand the ethical issues
that are an integral part of research using human subjects. In stating
these principles, the objective is to provide an analytical framework
that will guide the resolution of ethical problems involving research
with human subjects.
Respect
for Persons
The first
principle, which in its practical application gives rise to the idea of
informed consent, is respect for persons. There are two ethical convictions
which are the basis of this principle. First, individuals should be treated
as autonomous agents. Second, individuals with diminished autonomy are
entitled to protection.
This
principle carries two moral requirements: that we acknowledge the autonomy
of individuals and protect those individuals with diminished autonomy.
'Me autonomous person is capable of choice, that is, capable of deliberation
about personal goals and acting freely in the pursuit of those goals.
To respect that autonomy is to allow the individual the freedom to pursue
those goals without interference when there are no compelling reasons
not to do so.
Although
the capacity for self-determination is expected to be part of the normal
maturation process, some individuals lose this capacity because of illness
or mental disability. So, not every individual is capable of self-determination,
and some individuals require extensive protection. The extent of the protection
afforded individuals who are considering participation in a research activity
depends upon an assessment of the risk of harm and the likelihood of benefit
from the research. These individuals must also enter into the research
activity voluntarily and with adequate information.
In its
practical application, this principle requires that autonomous individuals,
insofar as they are capable, be given the opportunity to choose what will
and what will not happen to them. The possibility of this occurring is
maximized when three standards for informed consent are satisfied. The
first of these standards is information, generally including the procedure,
purpose of the research, possible risks, anticipated benefits, and opportunity
to ask questions and withdraw from the study. A simple listing of these
items does not convey the full meaning of all of what is meant by the
term information. A general rule often used to determine what information
to give requires the researcher to provide information that reasonable
persons would wish to know in order to make a decision regarding their
care. Even then, subjects should clearly understand the range of the probable
risks and the voluntary nature of their participation. Information concerning
risk should never be withheld for the purpose of eliciting the cooperation
of subjects, but care should be taken to avoid disclosures which would
invalidate the research. The second standard to insure informed consent
is comprehension. This standard is met when the information is conveyed
in a manner that the subject can understand. This means that the researcher
must adapt the presentation of the information to the subject's capacities
for intelligence, rationality, language, and level of maturity. The obligation
of the researcher to determine whether or not the subject comprehends
the information increases with the seriousness of harm and probability
of risks.
The third
standard for informed consent is voluntariness. Agreement to participate
in research is valid only if the consent is voluntary. This means that
the consent must be obtained without coercion, undue influence, unjustifiable
pressure, or deception.
Beneficence
The second
principle which the Commission established to guide resolution of ethical
issues inherent in research was the principle of beneficence. This is
the obligation to secure the wellbeing of participants in research by
maximizing possible benefits and minimizing possible harms. In practical
terms, this involves determining when it is justifiable to seek certain
benefits despite the risks and when the benefits should be abandoned because
of the risks.
The assessment
of benefits and risks is concerned with the probabilities and magnitudes
of possible harms, such as psychological, physical, legal, social, and
economic harm, measured against the possible benefits to the subject and
to society. This assessment of risks and benefits requires the researcher's
careful consideration of data, including consideration of alternate means
of obtaining the same research information, and concern for the subject,
subject's family, and society at large. This is accomplished by a systematic,
non-arbitrary approach by the reviewing committee which requires those
making decisions about the justifiability of the proposed research to
be thorough in gathering and assessing information about all aspects of
the research.
This
includes a determination of the presuppositions of the research, clarification
of the probability and magnitude of risk, and estimation of compliance
with five considerations: (a) brutal and inhumane treatment is never justified;
(b) risks are reduced to those necessary to obtain the research goals;
(c) if risk involves the possibility of serious impairment, review committees
should require a very high level of justification; (d) the use of vulnerable
populations must be justified; and (e) relevant risks and benefits must
be communicated to the subject in the appropriate language.
Justice
The third
principle is justice, which requires that there be fair procedures and
outcomes in the selection of research subjects. The question is: Who ought
to receive the benefits of research and who ought to bear its burdens?
This principle is applicable at both individual and social levels.
At the
individual level, research is constrained to offer the benefits of research
to all subjects and not to seek vulnerable subjects for research
procedures involving higher levels of risks.
Social
justice requires that a distinction be made with respect to the ability
of the social class selected for research to bear the burdens of the research.
For example, this moral requirement would require the selection of adults
before children, all other factors being reasonably equal. Thus, the selection
of research subjects needs to be examined in order to determine whether
some classes (racial and ethnic minorities, welfare recipients, children,
or prisoners) are being selected simply because of their easy availability,
rather than for reasons directly related to the problem under investigation.
Except where research is directly related to the specific conditions of
the class involved, it seems unfair that populations dependent on public
health care constitute a pool of preferred research subjects if more advantaged
populations are likely to be the recipients of the benefits of the research.
Justice
demands that benefits coming out of publicly funded research be available
to all individuals and not just to those who can afford the benefits,
and that publicly funded research not be confirmed to groups of individuals
who are unlikely to be among the recipients of the benefits.
This
principle is more often than not overlooked. Therefore, the IRB must exercise
a heightened degree of vigilance to insure that the principle of justice
is fully applied to proposed research.
Summary
The Belmont
Report attempts to summarize the basic ethical principles identified by
the Commission in the course of its deliberations. The Commission was
charged to consider the boundaries between medical/lbehavioral research
and medical practice, the role of risk benefit assessment, the appropriate
guidelines for selection of human subjects, and the nature and definition
of informed consent.
The report
is a statement of basic ethical principles and guidelines to assist scientists
in resolving the ethical problems surrounding the conduct of research
with human subjects.
