A patient who is unable to make a decision about a complex proposal is not necessarily incapable of making any decisions at all, and may be perfectly able to consent where the issues are simpler. The starting point in the case of adults is always to presume that the patient has capacity until it is shown otherwise. The patient must have sufficient information to make a choice — without adequate information, patients are unable to make decisions about their treatment.
In research involving adult subjects with mental illnesses or cognitive impairments, the IRB and investigator s must be knowledgeable about the condition and any level of impairment that is likely to be present in the subject population. This is achieved either by having members with the appropriate experience and expertise or inviting consultants with competence in the special area to assist in the review of issues that require expertise beyond or in addition to that available on the IRB 45 CFR Ensuring such expertise on the IRB improves its ability to make determinations about subject recruitment, enrollment, and informed consent requirements that best match the needs of the subjects.
In some research, such as longitudinal studies involving progressive disorders or aging populations, enrolled subjects may be competent to consent on their own behalf at the outset, yet may experience effects of progressive or intermittent disorders that lead to decisional impairment during the course of the study. In these situations IRBs and investigators should consider the need to discuss with the prospective subjects whether they should designate someone to serve as a legally authorized representative at the outset of the study, consistent with all applicable laws.
Permission means the agreement of parent s or guardian to the participation of their child or ward in research 45 CFR In the United States the legal age of adulthood is a matter of state and local law. This means that who is legally considered a child may vary from state to state; in a large majority of states 18 years of age is the legal age of adulthood, but this is not true in every state, locality, or territory.
State law also may address specific circumstances in which a person younger than the age of adulthood is legally authorized to consent to medical procedures: for example, some states allow children younger than the legal age of adulthood to consent to the provision of contraceptive services.
Certain states provide a mechanism for the emancipation of minors, through which a child younger than the legal age of adulthood may gain certain civil rights, which might include the legal ability to consent to research participation. The definition of children also takes into account the particular interventions or interactions involved in the proposed research e.
For example, in some places individuals who are 16 years of age may legally consent to certain clinical interventions or interactions. If the involvement of human subjects in a proposed research activity consists of these interventions or interactions, then those individuals may be considered as adults for that purpose.
If a proposed activity includes an intervention or interaction for which the subject has not yet reached the legal age of consent, however, that person must be considered a child. Where research is conducted under 45 CFR Although the regulations state that children are unable to provide legally effective informed consent to participate in research, some might be able to give their assent. Mere failure to object should not, absent affirmative agreement, be construed as assent 45 CFR If the IRB determines that the capability of some or all of the children is so limited that they cannot reasonably be consulted regarding assent, or that the intervention or procedure involved in the research holds out a prospect of direct benefit that is important to the health or well-being of the children, and is available only in the context of the research, the assent of the children is not a necessary condition for proceeding with the research.
Even where the IRB determines that the subjects are capable of assenting, the IRB may still waive the assent requirement under certain circumstances in accord with 45 CFR Waiver or alteration of the requirements for obtaining informed consent from adult subjects can occur under any of the following three provisions:.
For research involving children, an IRB may waive the requirements for obtaining parental or guardian permission under any of the following four provisions:. The Office for Human Research Protections OHRP notes that informed consent should be viewed as an ongoing process throughout the duration of a research project. Unless the Institutional Review Board IRB determines that the requirements for obtaining informed consent can be waived, the investigators should seek and obtain the legally effective informed consent, as described in 45 CFR This is because the prior parental permission and child assent are not equivalent to legally effective informed consent for the now-adult subject.
The HHS regulations allow the IRB to waive the requirement for obtaining informed consent or parental permission or to approve a consent procedure that leaves out or alters some or all of the elements of informed consent otherwise required under 45 CFR For example, some research about natural behavior may require that subjects be unaware that the research is taking place.
Such research can only be approved by the IRB if the research meets the criteria for a waiver of informed consent under HHS regulations and for approving research according to 45 CFR Such research designs do not preclude offering potential subjects some information about the research and giving them the opportunity to decide whether to participate.
The IRB may approve such research in which investigators will leave out or alter elements of informed consent, so long as the research meets the criteria for approving research in 45 CFR The conditions under which an IRB may waive the requirement for obtaining informed consent or parental permission or may approve a consent procedure that leaves out or alters some or all of the elements of informed consent derive from four sources in the HHS regulations.
Under 45 CFR Note that this criterion means that only public benefit or service program research activities that are under state or local authority meet this criterion; similar research conducted under federal authority would not qualify here and is treated elsewhere in the regulations. Research conducted by or subject to the approval of only a private entity also would not qualify.
This criterion means that the practical circumstances of the research are such that the research is not feasible if the informed consent of the subjects must be obtained. For example, a study of identifiable private information about program benefit recipients using year-old records might meet this criterion, if current contact information for those recipients is not available. This waiver applies to research involving adults or children, but does not apply to research involving pregnant women, human fetuses, neonates of uncertain viability, and nonviable neonates, or prisoners.
It should be noted that FDA also has a comparable provision for a waiver of informed consent for emergency research at 21 CFR When an Institutional Review Board IRB has not waived the requirement for seeking prospective informed consent of the subjects or the parental permission of children who are subjects, under the HHS regulations at 45 CFR Some subjects might refuse a copy of the consent form once signed out of concern that their possession of the form could compromise their privacy.
The investigator may document that the subject refused a copy of the informed consent document and still include the subject in the study. In cases in which the documentation requirement is waived, the IRB may require the investigator to provide subjects or the parents of children who are subjects with a written statement regarding the research.
An IRB may waive the requirements for obtaining parental or guardian permission if either of the following two conditions is met:.
No, the IRB is responsible for deciding whether child assent is required in proposed research activities. Child assent is required, except in the following three circumstances described at 45 CFR The HHS regulations do not require documentation of assent.
The IRB has the discretion to determine the appropriate manner, if any, of documenting child assent. If young children are involved who are as yet unable to read, documentation should take a form that is appropriate for the purpose of recording that assent took place. The IRB may also decide that documentation of assent is not warranted.
In general terms, the regulations stipulate that an investigator should seek consent only under circumstances that provide the prospective subject or the legally authorized representative sufficient opportunity to consider whether to participate and that minimize the possibility of coercion or undue influence.
The information provided should be in language that is understandable to the subject or the representative. No informed consent, whether oral or written, may include any exculpatory language.
It is important to note that the informed consent requirements in the regulations are not intended to preempt any applicable federal, state, or local laws that require additional information to be disclosed for consent to be legally effective 45 CFR To sign up for updates or to access your subscriber preferences, please enter your contact information below.
A-Z Index. What is informed consent and when, why, and how must it be obtained? Is it possible to obtain legally effective informed consent to research in an urgent or emergency care setting? What are the basic elements of informed consent? What additional information might be appropriate to provide during the consent process? Can consent or parental permission ever be "passive" or "implied?
What does it mean to minimize the possibility of coercion or undue influence? When does compensating subjects undermine informed consent or parental permission? Can non-financial enrollment incentives constitute undue influence? If the subject or the legally authorized representative is asked to provide broad consent, the following shall be provided to each subject or the subject's legally authorized representative:. This description must include sufficient information such that a reasonable person would expect that the broad consent would permit the types of research conducted;.
California Experimental Subject's Bill of Rights :. Informed consent is when a healthcare provider — like a doctor, nurse, or other healthcare professional — explains a medical treatment to a patient before the patient agrees to it. This type of communication lets the patient ask questions and accept or deny treatment. These components are essential elements of the shared decision-making process between you and your healthcare provider.
Most importantly, it empowers you to make educated and informed decisions about your health and medical care. When your healthcare provider recommends specific medical care, you can agree to all of it, or only some of it. This form is a legal document that shows your participation in the decision and your agreement to have the procedure done.
In some cases, another person can sign a consent form for you. This is appropriate in the following scenarios:. Implied consent is a type of informed consent. For example, if you have a fever and see a healthcare provider, your visit implies that you want treatment.
Another example is if you break an ankle and visit a healthcare provider for crutches. Compared to informed consent, implied consent is less formal. Informed consent for research or clinical trials is also required.
It informs the participants about the trial and lets them make educated decisions about taking part in the study.
