and fetuses
Research with prisoners
Research with subjects who are not competent to provide consent
Research
involving subjects with reproductive potential
Certain kinds of subject populations
are recognized as being more vulnerable
than others. Federal regulations recognize
and protect minors, pregnant women, fetuses
in utero and prisoners in this way. This
section describes some of these populations
and the special protections they enjoy.
Research with minors
Research involving persons below the legal age of consent is important for the health and well-being of all children, and may be conducted by faculty, staff, and students of the UW provided the Human Subjects Review Committee (and where applicable, those of its affiliated institutions where such research will be performed), has determined that:
- studies, where appropriate, have been conducted first on animals, adult
humans, then on older children, before involving infants;
- risks are minimized by using the safest procedures consistent with sound
research design; and
- adequate provisions are made to protect the privacy
of subjects and their families, and to maintain confidentiality of data.
- Permission of Children and Parents or Guardians
- Adequate provisions must be made for soliciting and documenting the
assent of children prior to their involvement as research subjects.
"Assent" in this context means the child's affirmative agreement to
participate, not merely the absence of his or her objection, after adequate
explanation. This differs from the term "consent," which indicates
voluntary participation by a person of legal age and competency who is able
to exercise free power of choice based on complete information. Assent must
be obtained from any child who might reasonably be expected to comprehend
the nature of his or her involvement in the research, regardless of age but
at least by seven years. Research protocols should include forms for
documentation of assent of subject children. Simplified written forms are
recommended for children of seven years and over, and forms documenting oral
assent for those under seven years or otherwise incapable of utilizing
written forms.
The only exceptions to this requirement for assent of the child are: a)
when the subject is incapable of comprehension or communication of
understanding and assent or b) when the research intervention holds out a
clear prospect of direct benefit that is important to the health or
well-being of the child and is available only in the context of the
research. In these cases, assent should not be offered. Under all other
circumstances, a child's objection to participation in research shall be
binding.
- Permission of the parent or legally appointed guardians must be
documented. Permission of one parent is sufficient only when one or
more of the following conditions apply:
- the risk of physical or psychological damage is minimal -- minimal risk
is defined here as not exceeding that normally encountered in the daily
lives, or in the routine medical, dental, or psychological examination of
healthy children;
- where the intervention holds out the prospect of direct
benefit for the individual subjects or represents a monitoring procedure
required for the well-being of the subjects;
- one parent is deceased,
unknown, incompetent, or not reasonably available, or the child has a
guardian or belongs to a single parent family, where only one person has
legal responsibility for the care, custody, and financial support of the
child.
- When parents of research subjects are under the legal age of consent, their
consent alone may be considered sufficient where they are "emancipated
minors," i.e., where they are maintaining their own residence and exercising
primary economic and social control of their own and the child's life. When
the parents of the child are dependent upon others for support, then consent
of those exercising ultimate economic and social control of the child's life
must also be obtained.
- When the research involves the diagnosis or treatment of diseases related to
reproductive health, minor subjects aged fourteen and older and subject to
the laws of the state of Washington may consent to their involvement in the
research without the permission of their parents.
- The Human Subjects Review Committee may waive the requirement for consent of
parents or guardians when a research protocol is designed for conditions
where such permission is not a reasonable requirement, provided an
appropriate mechanism for protecting the subjects is substituted. Examples
might include some research involving abused or neglected children, or high
school and college students engaged as subjects in classroom projects
involving minimal risk. One alternative which may be used under these
circumstances is the appointment of a social worker, physician, nurse,
school authority, or other individual to act as surrogate parent. A person
so appointed would be expected to participate not only in the process of
solicitation of the child's assent, but also in the conduct of the research,
in order to provide reassurance for the subject and to intervene or support
the child's desire to withdraw if participation becomes too stressful.
- Degree of Risk Involved
- Research on children which involves more than a minimal risk (as defined in
section VII..P) may be conducted when it holds out the clear prospect of
direct benefit to the individual subjects, or contributes to their
well-being. The degree of risk involved under these circumstances must be
justified by the anticipated benefit to the subjects, and the relation of
anticipated benefit to such risk is at least as favorable to the subjects as
that presented by available alternative approaches.
- Research on children involving more than minimal risk, which does not hold
out the prospect of direct benefit for the individual subjects, may be
conducted when the degree of risk represents a minor increase over minimal
risk and when one of the following circumstances apply: 1) the degree of
risk involved is reasonably commensurate with that ordinarily experienced by
the subjects by virtue of being treated for their specific disorder or
condition; 2) the anticipated knowledge is likely to be of substantial
benefit to another family member, or is likely to yield generalized
knowledge about the subject's disorder or condition which is of vital
importance for understanding or ameliorating that disorder or condition in
others.
- Research that cannot be approved under the guidelines of the preceding
paragraphs because of the substantial increase in degree of risk or for
other reasons may be conducted only after: 1) the Human Subjects Review
Committee has determined that such research presents an opportunity to
understand, prevent, or ameliorate a serious problem affecting the health
or welfare of children; and 2) the Secretary of the DHHS or his or her
designate, after consultation with a panel of experts in pertinent
disciplines, has reached a similar conclusion; and 3) that the proposed
research will be conducted in accordance with basic ethical principles, with
adequate provisions for soliciting the assent of children and the permission
of their parents or guardians.
- Special Custodial Circumstances
- Children who are wards of the State should not be involved in research
involving more risk than that normally encountered in the lives of healthy
children, unless 1) such research is related to their social status as
orphans, abandoned children, or the like, or to their medical status, such
as blind or mentally retarded; or 2) the research is conducted in a group
setting, such as a school, wherein the majority of subjects are not wards of
the State. Under either of these circumstances an advocate for each child
must be appointed, with an opportunity to intercede that would normally be
provided by parents. One individual may serve as advocate for more than one
child, but no advocate may be used who is an employee of the institution
responsible for the research.
- When children reside in treatment facilities, in foster homes, or other
custodial circumstances where they are in the care of persons with the right
to act in loco parentis, and when the parents are not available, an
advocate shall be appointed for each child. Permission for participation
in research under these circumstances must be granted by any individual acting
in loco parentis, in addition to the advocate. Conditions governing
assent of the child shall be the same as for other children as outlined
above.
Research with pregnant women and fetuses
No research activity involving pregnant women as subjects may be conducted unless:
- appropriate studies on animals and non-pregnant individuals have been completed;
- except where the purpose of the activity is to meet the health needs of the mother or the particular fetus, the risk to the fetus is minimal and, in all cases, is the least possible risk for achieving the objectives of the activity;
- individuals engaged in the activity will have no part in:
- any decisions as to the timing, method, and procedures used to terminate the pregnancy, and
- determining the viability of the fetus at the termination of the
pregnancy;
and
- no procedural changes which may cause greater than minimal risk to the fetus or the pregnant woman will be introduced into the procedure for terminating the pregnancy solely in the interest of the activity. No inducements, monetary or otherwise, may be offered to terminate pregnancy for purposes of the activity.
Research on pregnant women may be conducted only if the woman and the prospective father are legally competent and have given their informed consent after having been fully informed regarding possible impact on the fetus. The father's informed consent need not be secured if:
- the purpose of the activity is to meet the health needs of the mother;
- his identity or whereabouts cannot reasonably be ascertained;
- he is not reasonably available; or
- the pregnancy resulted from rape.
Research on fetuses in utero may be conducted if:
- the purpose of the activity is to meet the health needs of the particular
fetus and the fetus will be placed at risk only to the minimum extent
necessary to meet such needs, or
- the risk to the fetus imposed by the research is minimal and the purpose of
the activity is the development of important biomedical knowledge which
cannot be obtained by other means.
If a fetus ex utero has been found to be viable, it may not be involved as a subject unless:
- there will be no added risk to the fetus resulting from the activity, and
the purpose of the activity is the development of important biomedical
knowledge which cannot be obtained by other means, or
- the purpose of the activity is to enhance the possibility of survival of the
particular fetus to the point of viability.
A nonviable fetus may be involved as a subject in an activity covered by this subpart if:
- vital functions of the fetus will not be artificially maintained,
- experimental activities which of themselves would terminate the heartbeat or
respiration of the fetus will not be employed, and
- the purpose of the activity is the development of important biomedical
knowledge which cannot be obtained by other means.
Research with prisoners
Research involving prisoner subjects always requires Human Subjects Review Committee review, unless all of the information to be used by investigators is within the public domain. Research with prisoners that involves more than minimal risk has essentially been prohibited by Federal regulations.
Research involving prisoners is limited to the following areas:
- study of the possible causes, effects, and processes of incarceration, and
of criminal behavior, provided that the study presents no more than minimal
risk and no more than inconvenience to the subjects;
- study of prisons as institutional structures or of prisoners as incarcerated
persons, provided that the study presents no more than minimal risk and no
more than inconvenience to the subjects.
Research may also be conducted on conditions particularly affecting prisoners as a class (for example, vaccine trials and other research on hepatitis, which is much more prevalent in prisons than elsewhere; and research on social and psychological problems such as alcoholism, drug addiction, and sexual assaults). The Human Subjects Review Committee will refer such applications to the Secretary of the Department of Health and Human Services. The study may proceed only after the Secretary has consulted with appropriate experts including experts in penology, medicine, and ethics, and published notice, in the Federal Register, of his intent to approve such research; or
Research on practices, both innovative and accepted, which have the intent and reasonable probability of improving the health or well-being of the subjects may also be conducted. If the study requires the assignment of prisoners to control groups that may not benefit from the research, the Human Subjects Review Committee will refer the application to the Secretary of the Department of Health and Human Services. The study may proceed only after the Secretary has consulted with appropriate experts, including experts in penology, medicine, and ethics, and published notice, in the Federal Register, of the intent to approve such research.
Any possible advantages accruing to the prisoner through his or her participation in the research, when compared to the general living conditions, medical care, quality of food, amenities and opportunity for earnings in the prison, may not be of such a magnitude that his or her ability to weigh the risks of the research against the value of such advantages in the limited choice environment of the prison is impaired.
The risks involved in the research should be commensurate with risks that would be accepted by non-prisoner volunteers.
Procedures for the selection of subjects within the prison must be fair to all prisoners and immune from arbitrary intervention by prison authorities or prisoners. Unless the principal investigator provides to the Human subjects Review Committee justification in writing for following some other procedures, control subjects must be selected randomly from the group of available prisoners who meet the characteristics needed for that particular research project.
The information about the study must be presented in language that is understandable to the subject population.
Adequate assurance must exist that parole boards will not take into account a prisoner's participation in the research in making decisions regarding parole, and each prisoner is clearly informed in advance that participation in the research will have no effect on his or her parole.
Where the Human Subjects Review Committee finds there may be a need for follow-up examination or care of participants after the end of their participation, adequate provision must be made for such examination or care, taking into account the varying lengths of individual prisoners' sentences, and for informing participants of this fact.
When the Human Subjects Review Committees review applications proposing to include prisoners as subjects, a prisoner advocate will be present for the deliberation.
Research with subjects who are not competent to provide consent
When legal incompetents (other than children) and adults unable to give informed consent are to be used as subjects in diagnostic or therapeutic research, the legally responsible adult must sign the consent form giving approval for participation in the activity. Consent by the subject may be desirable, as well, but usually is optional. When neither diagnostic nor therapeutic procedures are involved, the legally incompetent's refusal to participate in non-therapeutic research is binding.
When there is a question about the competency of an adult who has not been declared legally incompetent, a subject advocate should participate in the consent process. The subject advocate should be able to attest to the subject's apparent understanding of the research or to the probable consent of the subject if he or she were competent. In this latter situation, the anticipated benefit to the subject should clearly outweigh the risks, if they are greater than minimal. Further, if there are any indications that he or she does not wish to participate, then the individual should be excluded from the study.
The subject advocate should be fully informed about the research and be a party, where possible, to the oral explanation given to the subject. The role of the subject advocate carries with it a shared responsibility for the welfare of the subject. Because of this responsibility, it may be desirable to involve the subject advocate, insofar as practicable, throughout the duration of the procedures or treatment.
The importance of the subject advocate increases with the risk to the subject. However, the subject advocate is intended as a protection and not as an obstacle in life-threatening situations where there are no alternative forms of treatment. Not all critically ill patients are "incompetent"; therefore an individual who has not been declared legally incompetent may choose to waive the right to a subject advocate by initialing the consent form where the subject advocate would otherwise sign. An investigator will want to consider such waivers very carefully.
Research involving subjects with reproductive potential
It is important to conduct research to be able to detect the effects of gender, where relevant. Therefore, researchers should include equitable numbers of men and women as research subjects. Subjects with reproductive potential (women of childbearing potential and fertile men) should not be excluded from research unless the health of the subject or the integrity of the research would be placed at risk. The decision to enroll subjects of reproductive potential in studies should be made after evaluating the risks demonstrated in studies with appropriate animal subjects, the probably risks to humans, the nature of the disease under study, and the potential benefits of the study results.
Researchers must counsel subjects of reproductive age to use an active method of contraception or abstinence for as long as there is risk to a fetus. This use may extend beyond the termination of the study, in some cases. Female subjects of reproductive age should have a pregnancy test performed before beginning the study. Researchers may also perform pregnancy testing at intervals throughout the study depending on the nature of exposure to the intervention that poses risk to the fetus. When adolescents are involved in studies as subjects, researchers must take particular care to preserve the confidentiality of information about sexual activity and contraception use when discussing these issues with the adolescents' parents.
Consent forms used for studies in which there is potential risk to subjects of reproductive age should explain these risks in lay language and should also explain the need for use of contraception.
