Brief Overview
With few exceptions, researchers must obtain and document
consent from the prospective research subject before initiating any screening
or study procedures. Any exceptions must be reviewed and approved by the
CHR beforehand.
Based on the governing principles of human research outlined in "The
Belmont Report" — respect for persons, beneficence,
and justice—research investigators have key responsibility
for ensuring voluntary participation of research subjects. The recruitment
plan, consent process and consent documents to be used with prospective
subjects must be carefully designed so that subjects’ consent
will be well-informed and freely given.
The Office for Human Research Protections (OHRP) and the Food and
Drug Administration (FDA) enforce federal regulations covering informed
consent in research involving human subjects.
These regulations are applied to all human research at UCSF.
The purpose of these guidelines is to assist investigators in planning
the consent process and consent documents to be used in their research
studies, in accord with federal regulations and UCSF standards.
Consent Process
and Documentation
Informed consent: Any individual (or their legally
authorized representative) who is asked to take part in a research
study should be able to understand as completely as possible what
procedures, risks, benefits, alternatives, and rights are involved,
and make the choice about being in the study without pressure or
undue inducement to participate.
Ongoing process: Free and informed consent is not one event but
an ongoing process. Throughout the study, participants must be told
about changes in the study, feel free to ask questions, and be allowed
to withdraw from the study at any time for any reason, or even for
no reason.
Documentation of informed consent: Federal and state
regulations direct that informed consent be documented, in general, with a written
consent form incorporating the required
elements of consent. The participant
or his/her legally authorized representative reads,
signs and dates the consent form. The person
obtaining consent also signs and dates the consent form. A signed copy of the
consent form is given to the participant or, when appropriate, to his/her legally
authorized representative.
For further details of federal and UCSF requirements for consent
documentation, see 45
CFR 46.117, 21
CFR 50, CHR Consent Form Standards and Sample
Consent and Assent Forms.
Exceptions to informed consent requirements: As discussed in detail
below, the CHR may approve exceptions to the general rule for informed
consent, including waiver of all consent, use of surrogate
consenters,
use of verbal consent, or use of a short-form
process for subjects
who cannot read English. Investigators must justify any of these
exceptions in their CHR applications.
Purpose of consent document: The form is one part of the entire
consent process. It serves as a written summary of the information
that was presented to prospective subjects before their agreement
to participate in a study, and thus provides a useful reference for
both the subject and the investigator.
Contacting prospective subjects: See UCSF Subject Recruitment guidelines
for more information on this topic.

Federal Requirements
for Informed Consent
Federal
regulations on informed consent (45 CFR 46.116) describe general
requirements for informed consent as follows:
Except as provided elsewhere in this policy, no investigator may involve
a human being as a subject in research covered by this policy unless the
investigator has obtained the legally effective informed consent of the
subject or the subject's legally authorized representative. An investigator
shall seek such consent only under circumstances that provide the prospective
subject or the representative sufficient opportunity to consider whether
or not to participate and that minimize the possibility of coercion or undue
influence. The information that is given to the subject or the representative
shall be in language understandable to the subject or the representative.
No informed consent, whether oral or written, may include any exculpatory
language through which the subject or the representative is made to waive
or appear to waive any of the subject's legal rights, or releases or appears
to release the investigator, the sponsor, the institution or its agents
from liability for negligence.
They then stipulate eight basic required elements of informed consent,
and six additional elements which may be added to a consent form when appropriate.
The eight required elements of consent are:
- “a statement that the study involves research, an explanation
of the purposes of the research and the expected duration of the
subject’s
participation, a description of the procedures to be followed,
and identification of any procedures which are experimental;
- a description of any reasonably foreseeable risks or discomforts to
the subject;
- a description of any benefits to the subject or to others which may
reasonably be expected from the research;
- a disclosure of appropriate alternative procedures or courses of treatment,
if any, that might be advantageous to the subject;
- a statement describing the extent, if any, to which confidentiality
of records identifying the subject will be maintained;
- for research involving more than minimal risk, an explanation as to
whether any compensation and an explanation as to whether any
medical treatments are available if injury occurs and, if so, what they consist
of,
or where
further information may be obtained;
- an explanation of whom to contact for answers to pertinent questions
about the research and research subjects' rights, and whom to
contact in the event of a research-related injury to the subject; and
- a statement that participation is voluntary, refusal to participate
will involve no penalty or loss of benefits to which the subject
is otherwise entitled, and the subject may discontinue participation at
any time without
penalty or loss of benefits to which the subject is otherwise
entitled.”
The six additional elements which may be added to a consent form when appropriate
are:
- “a statement that the particular treatment or procedures may involve
risks to the subject (or to the embryo or fetus, if the subject
is or may become pregnant) which are currently unforeseeable;
- anticipated circumstances under which the subject’s participation
may be terminated by the investigator without regard to the subject’s
consent;
- any additional costs to the subject that may result from participation
in the research;
- the consequences of a subject's decision to withdraw from the research
and procedures for orderly termination of participation by the
subject;
- a statement that significant new findings developed during the course
of the research which may relate to the subject's willingness
to continue participation will be provided to the subject; and
- the approximate number of subjects involved in the study.”
In addition, DHHS provides guidance
regarding possible conflict of interest in research, including consent form
recommendations. Investigator
Conflicts of Interest and CHR Review should be consulted for UCSF guidance
in this regard.

CHR Consent
Form Standards
In preparing any UCSF consent form or information
sheet, the researcher should follow the CHR standard format, adapting
as necessary and appropriate.
The goal of the CHR standard format is to create a document that
satisfies federal and institutional consent requirements, and presents
all needed information in a way that is as clear and easily readable
as possible to the prospective subject.
The CHR standard format incorporates OHRP and FDA regulations. The CHR Standard
Format was updated in 2004 to reflect consent
form recommendations by the National Cancer Institute (NCI).
General information and a section-by-section
discussion of CHR’s
standard format are provided below. Also see Sample Consent and
Assent Forms for examples.
General Information
- Eighth grade reading level: The consent document should
be written at the most likely level of understanding of the subject
population—in general, an eighth grade reading level is recommended.
Everyday vocabulary and simple sentence structure should be used
throughout. Researchers always have the option of describing the
study in more detail or more scientific language during the consent
process (if appropriate). But the initial written description of
the study should be simple and straightforward, so that subjects
will have an easily understood consent form to take home and refer
to.
- Using lay language instead of medical terminology: Unless
the subjects are themselves medical professionals, scientific or
technical terms should be replaced with or defined in lay language
(e.g., "blood draw" is preferable to "venipuncture," "x-ray" to "radiographs," "upset
stomach" to "GI upset”).
- Avoiding legalistic language: Legal-sounding language such
as "You hereby agree," "You certify that," "You,
the undersigned, do acknowledge that," or “You understand
that” is unnecessary and should not be used.
- Person of the form: The NCI recommends a “Q&A” format,
with the section headings written as questions from the subject’s
viewpoint (first person–“I”), and answers/other
information written from the investigator’s viewpoint addressing
the subject (second person–“you”). This format
is preferred for all adult consent forms. Minors’ assent
forms may be written entirely in the second person of the subject.
In either
case, the chosen format should be consistent throughout the form.
- Avoiding “you/your child” format:
Using wording like “you/your child” throughout a consent form
(in order to use the same form with adult subjects and parents giving permission
for their children to be subjects) is confusing and should be avoided.
See CHR guidance on consent for children and Sample Consent and
Assent Forms for better ways to approach this problem.
Section by Section Discussion
For detailed guidance about information and wording which the CHR
prefers in each section of the consent form, see CHR
Consent Form Standards – Section by Section Discussion.

Consent and Assent Forms.

Other IRBs’ Consent
Form Requirements
A UCSF investigator may wish to conduct research
at another study site where the institutional review board has different
standards for consent documentation. In such cases, the CHR will
consider a request to approve use of the other IRB's approved consent
form or information sheet, as long as it satisfies the federal requirements
for informed consent. The request and the explanation for this should
be included in the cover letter of the application.
See Working with Other Institutions and Units for additional information.
Top of Page
Consent by Surrogates/Legally
Authorized Representatives
In general, participation in research should be limited
to individuals who can give informed consent for themselves. In special
cases where this is not possible, federal and state regulations provide
that consent may be given by the subject’s surrogate or legally
authorized representative.
For more detailed information on relevant federal, state, and University
of California requirements, see Surrogate
Consent.
NOTE: Parents’ or legal guardians’ consent
(permission) for children to participate in research is covered separately
under Minors
in Research.
Top of Page
Waiver of All Consent
NOTE: For chart on regulations pertaining to this and
the next section, see 45
CFR 46.116 and 46.117; 21 CFR 50.23 and 50.24; 21 CFR 56.109: Waiver
of Consent vs. Waiver of Signed Consent.
In certain cases, federal regulations allow the CHR to approve a
consent procedure which does not include, or which alters, some or
all of the elements of informed consent, or to waive the requirement
to obtain any informed consent. Most complete waivers of consent
involve studies in which there are minimal risks to subjects, but
complete waivers are also possible in emergency care and a few other
circumstances.
NOTE: FDA
regulations (21 CFR 50 and 56) differ from DHHS regulations (21
CFR 46) and are generally more restrictive. The differences are
noted below.
Minimal Risk Studies
Federal regulation 45
CFR 46.116(d) establishes four criteria for
waiving consent or altering the elements of consent in minimal
risk studies. There are no corresponding provisions in FDA regulations,
and these criteria may not be used to waive or alter the elements
of consent in FDA-regulated studies:
- The research involves no more than minimal
risk;
- The waiver or alteration will not adversely affect the rights
and welfare of the subjects;
- The research could not practicably be carried out without
the waiver or alteration; and
- Whenever appropriate, the subjects will be provided with
additional pertinent information after participation.
Minimal risk is defined in 45
CFR 46.102 as “the probability
and magnitude of harm or discomfort anticipated in the research
are not greater in and of themselves than those ordinarily
encountered
in daily life or during the performance of routine physical
or psychological examinations or tests.”
| Example of approvable waiver of consent |
Study to determine whether some specific
blood chemistry values change in people undergoing clinically
indicated abdominal surgery,
and if there is a correlation of changes with increased incidence
of complications after surgery.
Involves review of medical records of all patients who have
undergone abdominal surgery in the past two years (about
10,000 surgeries), collecting limited data
that will be double-coded so link is known only to researchers. Results of
the research will not affect clinical care of the individuals,
since they will already
have left the hospital. |
| 1) Minimal risk: Fits definition. |
| 2) Would not adversely affect rights
and welfare of subject:
Surgery and associated blood chemistry values are clinically
indicated, therefore would be done regardless of the research.
No study results would affect clinical decisions about the individual's
care. |
| 3) Research could not be practicably carried out without
the waiver: Identifying and contacting thousands of potential subjects,
while not impossible, would not be feasible for a medical record
review where results would not change care the individuals already
would have received. (Note: In smaller studies, it is harder
to argue that obtaining consent is not feasible, especially if
subjects have not yet been treated or are still being seen.) |
| 4) Whenever appropriate, subject provided with additional
pertinent information after participation: Not appropriate in this case,
since results of research would have no effect on the subjects;
there is no anticipated benefit to subject that would change
what has already occurred. |
(Above example adapted from Institutional Review Board: Management
and Function, R. Amdur and E. Bankert, Chap. 6-6, "Research
without Consent or Documentation Thereof," M. M. Elliott.)
Waiving consent versus obtaining consent from a surrogate/legally
authorized representative: When prospective research participants
in minimal risk studies cannot consent for themselves because they
are incapacitated in some way, the researcher must decide whether
to request a waiver of all consent or use of a surrogate
consenter/legally authorized representative.
-
Ethically, it is usually preferable to use a surrogate who knows
the subject’s wishes rather than waive consent entirely.
However, these concerns are less serious for studies with minimal
risks. Consent can be waived completely if the study is not
practicable without the waiver.
- If surrogates will be asked
to give consent, even for studies involving minimal risk, the
standard procedures for identifying a legally
authorized representative and obtaining surrogate consent must be followed (see
Surrogate Consent and UCOP
Guidance on Surrogate Consent for
Research).
It may not be practicable to follow this process for some minimal
risk studies, in which case a waiver of all consent should
be requested.
NOTE: When Surrogate Consent is used in a study, there are strict
requirements for obtaining additional consent when the subject
becomes competent, especially if there are any continuing or
followup procedures.
Consent for continuing or followup procedures after initial
waiver of consent: In occasional minimal risk studies, the
CHR may waive
consent when subjects initially cannot consent for themselves,
but require consent for later procedures when subjects recover
their
capacity to consent.
- Examples where followup consent might be required:
The CHR approves waiver of consent for a minimal risk blood
draw from patients
arriving unconscious at the emergency room. But if the researchers want any
procedures (e.g., blood draws, tests, collection of information
from records) to continue after subjects become competent to consent,
or want the subjects to participate in follow-up procedures
(e.g., interviews, office visits, or additional tests or medical record
review), then the CHR would probably require that signed
consent be obtained before research on that participant could
continue.
- Contents of followup consent: The consent form should clearly describe
what procedures occurred without the subject’s consent,
why they were performed, and what additionally will be done
if consent
is given to continue the subject in the study. The subject
must also be given the option of refusing to allow the researchers
to use the
data already collected.
Providing additional pertinent information: One requirement
when consent is waived in minimal risk studies is that “Whenever
appropriate, the subjects will be provided with additional pertinent
information after participation” [45
CFR 46.116(d)].
- There are no strict rules for deciding when it is “appropriate” to
provide additional pertinent information; but the CHR will
apply some general standards, as below, in considering
such requests.
- If consent is waived because it is not practicable to
obtain consent from large numbers of patients for a retrospective
chart review study,
generally it also will not be appropriate to attempt to
contact those patients to tell them about the study retrospectively.
- If consent is waived because subjects are temporarily
incapacitated, it may well be appropriate to provide them
with information
later, and even, as noted above, to obtain consent for
ongoing research.
APPLICATION NOTE: Investigators should specifically address
arguments for waiver of standard consent procedures in
the CHR Application,
Part 8- Consent Process and in the form Appendix:
Request for Waiver of Consent/ Authorization for Minimal
Risk Research
or for Screening
for Recruitment.
Research in Emergency Settings – More than Minimal
Risk
Federal regulations (21
CFR 50.24; see also OPRR
Reports 10/31/96) allow for waiver of consent in situations
where there is more
than minimal risk to participants, provided there is
a prospect of direct
benefit to participants and a number of other
conditions are met.
This waiver applies to both FDA- and DHHS-regulated studies. The conditions include
the following:
- The study could not practicably be carried out without
the waiver.
- Consultation with community representatives occurs before
the study starts.
- Public disclosure is
made before and after the study.
- A therapeutic window is defined,
and the researcher commits to trying to locate a surrogate/legally authorized representative who
can give consent within that window before proceeding
to waive consent.
Meeting all of the conditions for waiver under these regulations
is arduous, but the regulations do allow research that otherwise
could not be approved. It may be worthwhile to consider this process
for research in circumstances where treatment must be provided quickly,
patients are incapacitated, and a legally authorized representative
is not readily available. Examples include research on cardiac arrest,
stroke, head trauma, spinal cord injury, gunshot wounds, and poisoning.
For more information on this type of waiver, see the CHR application
supplement Emergency Medical
Research: Waiver of Informed Consent and the extended discussion in Research in
Emergency Settings.
IMPORTANT NOTE: Emergency
and Compassionate Use of Experimental Drugs and Devices is usually distinct
from planned research in emergency settings. Planned research in emergency settings
involving a waiver of informed consent requires compliance with the conditions
discussed in this section. Most emergency and compassionate use does not involve
waiver of consent and usually, when provided to a single patient,
is not considered research
by DHHS and is considered research but is exempted from prior CHR approval by
the FDA. Physicians should consult with the CHR prior to such use if
at all possible, and are required to report to the CHR after any such use.
For more information on this topic, follow the link given above.
Public Benefit or Service Program Studies
Federal regulation 45
CFR 46.116(c) provides for waiving consent
in the following circumstances. (Note: To date, the CHR has never
seen a study that satisfies these requirements; these provisions
do not apply to FDA-regulated studies).
- The project is to be conducted by or subject to the approval
of state or local government officials and is designed
to study, evaluate,
or otherwise examine: (i) public benefit or service programs;
(ii) procedures for obtaining benefits or services under those programs;
(iii) possible changes in or alternatives to those programs
or procedures; or (iv) possible changes in methods or levels of
payment for benefits
or services under those programs; and
- The research could not practicably be carried out without
the waiver or alteration.
Waiver of Signed Consent/Obtaining Verbal or Implied Consent
NOTE: For chart on regulations pertaining to this and the previous
section, see 45 CFR
46.116 and 46.117; 21 CFR 50.23 and 50.24; 21 CFR 56.109: Waiver
of Consent vs. Waiver of Signed Consent.
Federal regulations [45
CFR 46.117(c)] allow the CHR to waive the
requirement for obtaining signed consent if it finds that either:
- The only record linking the subject and the research
would be the consent document and the principal risk would be potential
harm resulting from a breach of confidentiality
(These criteria cannot be used for FDA-regulated studies),
or
- The research presents no more than minimal risk of harm
to subjects and involves no procedures for which written consent
is normally
required outside of the research context.
This paragraph only also applies to FDA-regulated studies
per 21
CFR 56.109(c)(1).
The CHR can also waive signed consent in studies that meet the requirements
for waiving all consent. The CHR will usually approve a request for
waiver of signed consent in the following situations; in most cases,
however, verbal consent (often with use of an information
sheet)
or implied consent will still be required.
| Examples of approvable waiver of signed consent |
| When the identities of subjects will be completely anonymous if the consent
form is not signed, and there is minimal risk involved in the study. |
| When obtaining signed consent is not appropriate or feasible according
to the cultural standards of the population being studied, and there is
minimal risk
involved in the study. |
| When there is a possible legal, social or economic risk to the subject
entailed in signing the consent form, e.g., for immigrants who might be
identified as being illegal aliens, or for HIV antibody-positive individuals
who might be identified as such by signing the consent form. |
| When the study involves only use of extra blood which is taken at the
time of a venipuncture being done for clinical reasons. |
Verbal Consent
Investigators may wish to replace signed consent with verbal
consent.
The CHR will consider approving such requests in limited circumstances,
and will usually require use of an information sheet. If this is
not feasible (for example, the only contact is by phone), the CHR
may ask to see a script of what would be said to prospective subjects
to evaluate the consent process.
Information Sheets
As the regulations state, "in cases where the documentation
requirement is waived, the IRB may require the investigator to provide
subjects with a written statement regarding the research." In
such cases, the CHR will usually call for use of an information
sheet that includes most or all of the elements of a consent
form but not the subject’s signature.
CONSENT NOTE: Consent forms and information sheets should be written
using the CHR Standard Format and Sample
Consent and Assent Forms.
Implied Consent
Investigators may wish to replace signed consent with implied
consent (e.g., a prospective subject is informed about a study where
participation consists only of filling out an anonymous questionnaire;
the person
completes the questionnaire and, by doing so, agrees to participate
in the research). The CHR will consider approving such requests
in limited circumstances, based on appropriate justification
and information regarding the consent process.

Short Form plus
Summary Consent with Non-English Speakers
In addition to the standard “written consent document that embodies
the elements of informed consent required by §46.116,” federal
regulation 45
CFR 46.117(as well as identical provisions in 21
CFR 50.27 for FDA-regulated studies) provides for use of an alternative form
of consent documentation as follows:
A short form written consent document stating that the
elements of informed consent required by §46.116 have been presented
orally to the subject or the subject's legally authorized representative.
When this method is used, there shall be a witness to the oral
presentation. Also, the IRB shall approve a written summary of what is to
be said
to the subject or the representative. Only the short form itself
is to be signed by the subject or the representative. However,
the witness shall sign both the short form and a copy of the summary,
and the person actually obtaining consent shall sign a copy of
the summary. A
[signed] copy of the summary shall be given to the subject or the
representative, in addition to a
[signed] copy of the short form.
[Bracketed words are additions to comply with California requirements.]
The CHR will consider a request to use this type of consent documentation
for the occasional and unanticipated non-English-speaking prospective
subject (see Informed
Consent for Research Subjects Who Do Not Read, Speak or Understand
English). However, the CHR discourages
any other use of this method.
Top of Page
Consent in Vulnerable
Subject Populations
The CHR must exercise special care when considering subjects whose
ability to give free and informed consent is compromised in any way.
Some studies propose to involve individuals who cannot give signed
or even verbal consent for themselves (e.g., young children, cognitively
impaired persons, unconscious patients), or people in other special
circumstances (e.g., pregnant women, prisoners). For further details on consent/assent requirements for such subjects,
see:
Vulnerable Subject Populations
