Nazi Data Case

A

Questions: “How should the Nazi data be regarded? Should it be used if it can save lives? Is the data tainted by the Nazi crimes or is it morally neutral information? Should researchers treat this data any differently than data gathered in more conventional ways?”

Argument for: We have a fundamental obligation to save lives and advance knowledge.

Argument against: Tainted knowledge, desecrating memory of the victims, makes us “on lookers to evil”

Ethic Requirements for Clinical Trials

A
  1. Informed Consent: Subjects must give their informed voluntary consent to participate.
  2. Minimize Risk: The study must be designed to minimize risks to subjects and offer an acceptable balance of risks and benefits.
  3. Confidentiality: The subjects’ privacy should be protected, and the confidentiality of research data must be preserved.
  4. Fairness/Justice: Subjects must be selected fairly to avoid exploiting or unjustly excluding them. (e.g. Race and Sex)
  5. IRB review (Institutional Research Board) Before the
    research is conducted, it mustbe reviewed and approved by an independent panel.

Q

Stages of Clinical Trials

A

— Phase I trial—Tests the drug in a few people for safety and adverse reactions and ascertains safe and unsafe doses (nontherapeutic).
— Phase II trial—Investigators give the drug to larger groups of subjects to get a preliminary indication of its effectiveness and to do more assessments of safety.
— Phase III trial—Researchers try to finally establish whether the drug is effective, determine how it compares with other proven treatments, and learn how to use it in the safest way (therapeutic; largest trials; capable of providing definitive answers about a treatment’s worth).

Q

Cornell Haiti Case Study

A

Case was about couples that had parter with HIV in Haiti, — Main Issue: Baseline treatment level for study?
(i) same as US standard of effective treatment?
or (ii) baseline of the country in question?

Arguments For: Baruch Brody

  1. Injustice to subject? – No, because subjects are not harmed relative to the baseline standard of care that otherwise should be available in light of practical realities of the country in question.
  2. Coercive Offers? - Not coercive, if there is (i) no threat, (ii) minimal risk (acceptable balance of risks and benefits), (iii) consent – to think otherwise is paternalistic and disrespectful.
  3. Exploitation of developing countries? (i) Local IRB approval; (ii) the subjects themselves should be guaranteed access to any successful therapies resulting from the studies.

Arguments Against: Marcia Angell
— Same standards as host country/USA. Best available treatment as control group or historical control group results – Otherwise it is analogous to the unethical Tuskegee study
— Additional issues – International exploitation of developing world as research subjects.
— Less regulated and competitive environments

Q

Arguments for confidentiality in reference to the moral principles

Q

Results of the Oken and Novak Study, and what they showed

A

Oken Study 1962:
◦ 12% of physicians disclose a diagnosis of cancer ◦ But 87% of patients want to know
Novak Study 1979:
◦ 98% of physicians report that their usual policy is
full disclosure of all serious medical conditions, including cancer.
Demonstrated a shift from paternalism to autonomy

26
Q

Hippocratic Approach to Medical Paternalism

A
  1. The main duty of a physician is to help (the principle of beneficence), but above all do no harm (the principle of non-maleficence).
  2. “Preserve life” is the fundamental goal of medicine. Death is always a harm, and it is thus a defeat of medical practice.
  3. Paternalistic authority: the physician is the judge of what is a benefit or harm to the patient.
27
Q

Autonomy model of consent

A
  1. The first duty is to respect patient autonomy and self-determination.
  2. In judging beneficence and non-maleficence, the physician must base these judgments on the particular patient’s values.
  3. The patient is the final judge of his or her own best interests, and thus of what is a benefit and what is a harm (the principle informed consent).
  4. The fundamental goal of medicine is to preserve thedignityofpatients. Thisusuallyinvolves saving lives and restoring health, but it may involve allowing “death with dignity”
28
Q

Kant views on self determinism vs. Mill’s views on self determinism

A

Kant: treating people as ends and not mere means includes respecting the capacity for self-determination.
Full disclosure respects patient autonomy and is necessary for effective self-determination.

Mill: “Each is the proper guardian of his own health, whether bodily, or mental, or spiritual. Mankind are the greater gainers by suffering each other to live as seems good to themselves, than by compelling each to live as seems good to the rest”

29
Q

Therapeutic Privilege Argument for and against full disclosure

A

For: truth-telling can be injurious, causing feelings of panic, hopelessness, fear, and depression.

Against: (1) Exaggerates the harm done to patients by full disclosure, underestimate the clinical beneficial effects of truthfulness – (next slide)
(2) fails to recognize that misleading or lying to patients can also do damage to patients non- health values – (see Goldman)

30
Q

Clinical Benefits of disclosure and informed consent

Sides for Presumed Consent Argument

A

Against : Patients do not want to know the truth, especially if the prognosis is grim.

For: Data from surveys suggest that most patients really do prefer to be told the truth about their diagnosis.

32
Q

Incapacity Consent Argument

A

For: Physicians have NO duty to tell patients the truth because patients are incapable of understanding the medical facts and probabilities, especially when faces with serious illness. (Lipkin article)

Counterargument: Even if communicating the whole truth is impossible, physicians still have an obligation to try to convey to patients the more essential information in an accessible and compassionate manner (Schwartz article)

4 Nobel Truths of Buddhism

A

The Truth of Suffering, Dukkha:
All existence is unsatisfactory and filled with suffering. Even those things that seem to bring joy and pleasure in the end are unsatisfying and unfulfilling, and thus leave us unhappy and craving for something more.

The Truth of the Arising of Suffering in Craving:
The root of suffering can be defined as a craving or clinging; the endless seeking for fresh experiences; the thirst for sensual pleasure, for existence, for non-existence. It is craving itself that gives rise to the endless cycle of rebirth.

The Truth of the Cessation of Suffering through Transcendence, Nirvana:
It is possible to find an end to all forms of suffering, through the cessation of craving with its associated attachment, hatred, and delusion, and thereby achieve liberation from the otherwise endless cycle of rebirth. The

Truth of the Noble Eightfold Path that leads to Nirvana:
The path is the Middle Way between a life of self indulgence and a life of harsh austerity or self denial. It involves wisdom, moral conduct, and transformative meditation:
