E Test 4 Flashcards
.What is the definition of Medical research?
Medical research involving human subjects includes research on identifiable human material or identifiable data. The primary purpose of medical research involving human subjects is to improve prophylactic, diagnostic and therapeutic procedures and the understanding of the aetiology and pathogenesis of disease. Even the best proven prophylactic, diagnostic, and therapeutic methods must continuously be challenged through research for their effectiveness, efficiency, accessibility and quality.
What is the duty of the physician?
To promote and safeguard the health of the people. The physician’s knowledge and conscience are dedicated to the fulfillment of this duty.
What should take precedence in medical research?
Considerations related to the well being of the human subject should take precedence over the interests of science and society.
What research populations are considered vulnerable and need special protection?
The particular needs of the economically and medically disadvantaged must be recognized. Special attention is also required for those who cannot give or refuse consent for themselves, for those who may be subject to giving consent under duress, for those who will not benefit personally from the research, and for those for whom the research is combined with care.
To whom should the experimental protocol be submitted?
This protocol should be submitted for consideration, comment, guidance, and where appropriate, approval to a specially appointed ethical review committee, which must be independent of the investigator, the sponsor or any other kind of undue influence. This independent committee should be in conformity with the laws and regulations of the country in which the research experiment is performed.
Who is responsible for the human subject?
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 consent. Medical research involving human subjects should be conducted only by scientifically qualified persons and under the supervision of a clinically competent medical person.
What is the role of risks and benefits to the subject?
Physicians should abstain from engaging in research projects involving human subjects unless they are confident that the risks involved have been adequately assessed and can be satisfactorily managed. Physicians should cease any investigation if the risks are found to outweigh the potential benefits or if there is conclusive proof of positive and beneficial results.
When is medical research justified?
Medical research is only justified if there is a reasonable likelihood that the populations in which the research is carried out stand to benefit from the results of the research.
What safeguards must be provided to research subjects?
Every precaution should be taken to respect the privacy of the subject, the confidentiality of the patient’s information and to minimize the impact of the study on the subject’s physical and mental integrity and on the personality of the subject.
What requirements are there for “informed”?
Each potential subject must be adequately informed of the aims, methods, sources of funding, any possible conflicts of interest, institutional affiliations of the researcher, the anticipated benefits and potential risks of the study and the discomfort it may entail. The subject should be informed of the right to abstain from participation in the study or to withdraw consent to participate at any time without reprisal.
For persons who are unable to give consent, what 2 requirements must be met?
i. The research is necessary to promote the health of the population represented
ii. This research cannot instead be performed on legally competent persons.
At the conclusion of the study, what must be assured to every patient?
At the conclusion of the study, every patient entered into the study should be assured of access to the best proven prophylactic, diagnostic and therapeutic methods identified by the study.
What was the charge of the commission?
To identify the basic ethical principles that should underlie the conduct of biomedical and behavioural research involving human subjects and to develop guidelines which should be followed to assure that such research is conducted in accordance with those principles.
What does “practice” refer to?
Refers to interventions that are designed solely to enhance the well-being of an individual patient or client and that have a reasonable expectation of success (i.e., practice of accepted therapy). To provide diagnosis, preventative treatment or therapy to particular individuals.
What does “research” refer to?
Designates an activity designed to test a hypothesis, permit conclusions to be drawn, and thereby to develop or contribute to generalizable knowledge (theories, principles, statements of relationships). Formal protocol that sets forth an objective and a set of procedures designed to reach that objective.
How is “experimental” and “research” different?
A procedure is “experimental” in the sense of being new, untested, or different, and therefore cannot be automatically placed in the category of research (i.e., the innovation does not constitute research as it it departs from standard or accepted practice). New procedures should be made the object of formal research at an early stage to determine whether they are safe and effective.
What are the three basic ethical principles?
(General judgements that serve as a basic justification for the many particular ethical prescriptions and evaluations of human actions)
i. Respect for persons
ii. Beneficence
iii. Justice
What are the 2 basic convictions related to respect of persons?
i. Individuals should be treated as autonomous agents (acknowledge autonomy)
ii. Persons with diminished autonomy are entitled to protection (protect those with diminished autonomy)
What are 3 examples to show lack of respect?
i. To repudiate that person’s considered judgements
ii. To deny an individual the freedom to act on those considered judgements
iii. To withhold information necessary to make a considered judgement, when there are no compelling reasons to do so
What are the 2 general rules of beneficence?
(Cover acts of kindness or charity that go beyond strict obligation)
i. Do not harm
ii. Maximize possible benefits and minimize possible harms
What is the principle of justice?
= “fairness of distribution,” or “what is deserved.”
Equals ought to be treated equally
Who is equal and who is unequal?
What considerations justify departure from equal distribution?
Look at distinctions based on experience, age, deprivation, competence, merit and position do sometimes constitute criteria justifying differential treatment for certain purposes
-individual and groups be treated fairly and equitably in terms of bearing the burdens and receiving the benefits of research
What are 5 formulations of the principle of justice?
Each formulation mentions some relevant property on the basis of which burdens and benefits should be distributed:
i. To each person an equal share
ii. To each person according to individual need
iii. To each person according to individual effort
iv. To each person according to societal contribution
v. To each person according to merit
Why does the selection of research subjects need to be scrutinized?
In order to determine whether some classes (e.g., welfare patients, particular racial and ethnic minorities, or persons confined to institutions) are being systematically selected simply because of their easy availability, their compromised position, or their manipulability, rather than for reasons directly related to the problem being studied.
What are the information requirements for informed consent?
Specific items for disclosure intended to assure that subjects are given sufficient information: research procedure, their purposes, risks and anticipated benefits, alternative procedures (where therapy is involved), and a statement offering the subject the opportunity to ask questions and withdraw at any time from the research.
What is the question that remains regarding informed consent?
Simple listing of items does not answer the question of what the standard should be for judging how much and what sort of information should be provided.
What are the 3 criteria to be met when incomplete disclosure is used?
i. Incomplete disclosure is truly necessary to accomplish the goals of the research
ii. There are no undisclosed risks that are more than minimal
iii. There is an adequate plan for debriefing subjects, when appropriate, and for dissemination of research results to them
How does comprehension impact informed consent?
The manner and context in which information is conveyed may adversely affect a subject’s ability to make an informed choice (e.g., presenting information in a disorganized and rapid fashion, allowing too little time for consideration or curtailing opportunities for questioning).
What are conditions in which it is necessary to adapt presentation for informed consent?
When comprehension is severely limited, by conditions of immaturity or mental disability.
What are the criteria used to select third parties for informed consent?
Those who are most likely to understand the incompetent subject’s situation and to act in that person’s best interest.
What is Voluntariness?
An agreement to participate in research constitutes a valid consent only if voluntarily given.
What are the two components of Voluntary consent?
i. Free of coercion (i.e., an overt threat of harm is intentionally presented by one person to another in order to obtain compliance)
ii. Free of undue influence (i.e., an offer of an excessive, unwarranted, inappropriate or improper reward or other overture in order to obtain compliance)
What is meant by the nature and scope of risks and benefits?
The requirement that research be justified on the basis of a favorable risk/benefit assessment bears a close relation to the principle of beneficence, just as the moral requirement that informed consent be obtained is derived primarily from the principle of respect for persons.
Risks and benefits of research may affect the individual subjects, the families of the individual subjects, and society at large (or special groups of subjects in society). Previous codes and Federal regulations have required that risks to subjects be outweighed by the sum of both the anticipated benefit to the subject, if any, and the anticipated benefit to society in the form of knowledge to be gained from the research. In balancing these different elements, the risks and benefits affecting the immediate research subject will normally carry special weight. On the other hand, interests other than those of the subject may on some occasions be sufficient by themselves to justify the risks involved in the research, so long as the subjects’ rights have been protected.
What is meant by “risk”?
Refers to a possibility that harm may occur
Small risk/high risk refer to the chance (probability) of experiencing a harm and severity (magnitude) of the envisioned harm
What is meant by “benefit”?
Refer to something of positive value related to health or welfare
Risk is contrasted to probability of benefits, benefits are contrasted with harms
What types of harm should be considered?
Psychological harm, physical harm, legal harm, social harm, economic harm
How does the principle of beneficence apply to risk of harm?
Beneficence requires that we protect against risk of harm to subjects and also that we be concerned about the loss of the substantial benefits that might be gained from research.
What is meant by the systematic assessment of risks and benefits?
Benefits and risks must be balanced and shown to be in favourable ratio. This ideal requires that those making decisions about the justifiability of research be thorough in the accumulation and assessment of information about all aspects of the research, and to consider alternatives systematically. This procedure is more rigorous and precise, making communication between review board members and investigators less subject to misinterpretation, and misinformation about conflicting judgements. Thus determine validity of the presuppositions of research, then distinguish the nature, probability, and magnitude of risk.
What are the five considerations for the justifiability of research?
i. Brutal or inhumane treatment of human subjects is never morally justified
ii. Risks should be reduced to those necessary to achieve the research objective. I.e., is it necessary to use human subjects at all?
iii. When research involves significant risk of serious impairment, review committees should be insistent on the justification of the risk (i.e., look at the likelihood of benefit to the subject?)
iv. When vulnerable populations are involved in research, the appropriateness of involving them should itself be demonstrated (i.e., nature ad degree of risk, condition of population, nature and level of anticipated benefits)
v. Relevant risks and benefits must be thoroughly arrayed in documents and procedures used in the informed consent process
How does the principle of justice impact the selection of subjects?
The principle of justice gives rise to moral requirements that there be fair procedures and outcomes in the selection of research subjects. Justice is relevant to the selection of subjects at two levels: individual level (fairness in not offering potential beneficial research to only some patients/ selecting undesirable persons for risky research), and social level (distinction should be drawn between classes of subjects that should or should not participate in research).
What sources of injustice are there?
Social, racial, sexual, and cultural biases institutionalized by society.
