    The emergence of bioethics

    I doubt whether it will ever be a discipline. It has become a meeting ground for a number

    of disciplines, discourses and organisations

    concerned with ethical, legal and social

    questions raised by advances in medicine,

    science and biotechnology. (Onora ONeill)

    The term, bioethics was coined in 1971, with

    the foundation of an institute in Washington

    DC. >> The Kennedy Institute for the Study of

    Human Reproduction and Bioethics

    Hippocratic Oath (Classical Version)

    I swear by Apollo Physician and Asclepius and Hygieia and Panaceia and all

    the gods and goddesses, making them my witnesses, that I will fulfil

    according to my ability and judgment this oath and this covenant:

    To hold him who has taught me this art as equal to my parents and to live

    my life in partnership with him, and if he is in need of money to give him a

    share of mine, and to regard his offspring as equal to my brothers in male

    lineage and to teach them this art - if they desire to learn it - without fee and

    covenant; to give a share of precepts and oral instruction and all the other

    learning to my sons and to the sons of him who has instructed me and to

    pupils who have signed the covenant and have taken an oath according to

    the medical law, but no one else.

    I will apply dietetic measures for the benefit of the sick according to my

    ability and judgment; I will keep them from harm and injustice.

    I will neither give a deadly drug to anybody who asked for it, nor will I make

    a suggestion to this effect. Similarly I will not give to a woman an abortive

    remedy. In purity and holiness I will guard my life and my art.

    I will not use the knife, not even on sufferers from stone, but will withdraw in

    favor of such men as are engaged in this work.

    Whatever houses I may visit, I will come for the benefit of the sick,

    remaining free of all intentional injustice, of all mischief and in particular of

    sexual relations with both female and male persons, be they free or slaves.

    What I may see or hear in the course of the treatment or even outside of the

    treatment in regard to the life of men, which on no account one must spread

    abroad, I will keep to myself, holding such things shameful to be spoken

    about.

    If I fulfil this oath and do not violate it, may it be granted to me to enjoy life

    and art, being honored with fame among all men for all time to come; if I

    transgress it and swear falsely, may the opposite of all this be my lot.

    Hippocratic OathModern Version Written in 1964 by Louis Lasagna, Academic Dean of the

    School of Medicine at Tufts University

    I swear to fulfill, to the best of my ability and judgment, this covenant: I will respect the hard-won scientific gains of those physicians in whose steps I walk, and gladly share such knowledge as is mine with those who are to follow. I will apply, for the benefit of the sick, all measures [that] are required, avoiding those twin traps of overtreatment and therapeutic nihilism. I will remember that there is art to medicine as well as science, and that warmth, sympathy, and understanding may outweigh the surgeon's knife or the chemist's drug. I will not be ashamed to say "I know not," nor will I fail to call in my colleagues when the skills of another are needed for a patient's recovery.

    Hippocratic OathModern Version Written in 1964 by Louis Lasagna, Academic Dean of the

    School of Medicine at Tufts University

    I will respect the privacy of my patients, for their problems are not disclosed to me that the world may know. Most especially must I tread with care in matters of life and death. If it is given me to save a life, all thanks. But it may also be within my power to take a life; this awesome responsibility must be faced with great humbleness and awareness of my own frailty. Above all, I must not play at God. I will remember that I do not treat a fever chart, a cancerous growth, but a sick human being, whose illness may affect the person's family and economic stability. My responsibility includes these related problems, if I am to care adequately for the sick. I will prevent disease whenever I can, for prevention is preferable to cure. I will remember that I remain a member of society, with special obligations to all my fellow human beings, those sound of mind and body as well as the infirm. If I do not violate this oath, may I enjoy life and art, respected while I live and remembered with affection thereafter. May I always act so as to preserve the finest traditions of my calling and may I long experience the joy of healing those who seek my help.

    Nuremberg Medical Trial

    and the Nuremberg Code

    1947

    Birth of the first international code concerning the ethical requirements of human experiments

    Stressing the importance of informed consent and the autonomy of research participants

  • 17

    NUREMBERG CODE, 1947

    1. The voluntary consent of the human subject is absolutely essential. This means that the person involved should have legal capacity to give consent; should be so situated as to be able to exercise free power of choice, without the intervention of any element of force, fraud, deceit, duress, over-reaching, or other ulterior form of constraint or coercion; and should have sufficient knowledge and comprehension of the elements of the subject matter involved as to enable him to make an understanding and enlightened decision. This latter element requires that before the acceptance of an affirmative decision by the experimental subject there should be made known to him the nature, duration, and purpose of the experiment; the method and means by which it is to be conducted; all inconveniences and hazards reasonable to be expected; and the effects upon his health or person which may possibly come from his participation in the experiment.

    The duty and responsibility for ascertaining the quality of the consent rests upon each individual who initiates, directs or engages in the experiment. It is a personal duty and responsibility which may not be delegated to another with impunity.

  • 18

    2. The experiment should be such as to yield fruitful results for the good of society, unprocurable by other methods or means of study, and not random and unnecessary in nature.

    3. The experiment should be so designed and based on the results of animal experimentation and a knowledge of the natural history of the disease or other problem under study that the anticipated results will justify the performance of the experiment. 4. The experiment should be so conducted as to avoid all unnecessary physical and mental suffering and injury. 5. No experiment should be conducted where there is an a priori reason to believe that death or disabling injury will occur; except, perhaps, in those experiments where the experimental physicians also serve as subjects. 6. The degree of risk to be taken should never exceed that determined by the humanitarian importance of the problem to be solved by the experiment. 7. Proper preparations should be made and adequate facilities provided to protect the experimental subject against even remote possibilities of injury, disability, or death.

  • 19

    Nuremberg Code

    9. During the course of the experiment the human subject should be at liberty to bring the experiment to an end if he has reached the physical or mental state where continuation of the experiment seems to him to be impossible. 10. During the course of the experiment the scientist in charge must be prepared to terminate the experiment at any stage, if he has probable cause to believe, in the exercise of the good faith, superior skill and careful judgment required of him that a continuation of the experiment is likely to result in injury, disability, or death to the experimental subject.

    Bioethics in the USA, problematic research on

    humans, the Tuskegee Syphilis study and genetic

    engineering

    Henry Beechers classic paper in the New England Journal of Medicine:

    Ethics and Clinical Research 74 (1966) 1354-60.

    The deliberate failure to treat a group

    of male Negroes in Macon County

    (near Tuskegee), Alabama who had

    syphilis begun in 1932 and ended, by

    unfavorable publicity, in 1972.

    At the end of the 1960s: New techniques for the direct manipulation

    of genes: genetic engineering.

    Tuskegee Syphilis study

  • 21

    Consequences

    The importance of individual autonomy (instead

    of collectivisim)

    The growing importance of human rights

    The social need for the transparency of scientific

    activities

    Insufficiency of the Hippocratic Oath

    Need for new medical norms and regulations

  • 22

    Medical ethics

    traditional and modern

    Hippocratic tradition

    List of professional

    moral duties

    From the perspective of

    the doctor

    Paternalism

    Argumentative

    Interdisciplinary

    Moral pluralism

    Patient perspective

    Stressing the autonomy

    of the patient

  • 23

    Bioethics as part of applied ethics

    Modern

    medical ethics

    Applied ethics

    Bioethics

    A quite frequent definition of

    bioethics as apllied ethics.

    Bioethics applies moral

    philosophical reasoning to

    the ethical problems arising

    in the diverse field of the

    lifesciences.

    criticism towards this idea that stresses moral

    philosophy in understanding

    these problems

  • 24

    The four principles approach (4PA)

    (Childress and Beauchamp, 1979)

    The four principles emerge from a rational reconstruction

    of common morality (the immediate moral

    intuitions/judgements) of ordinary people.

    Respect for autonomy

    Non-maleficence

    Beneficence

    Justice

  • 25

    Attractions and Critiques of 4PA

    its simple structure

    its apparent ability to make a deeper understanding of, and engagement with moral theory unnecesserary

    its apparent congruence with common features of moral thinking

    the derivation of the 4 principles from moral theory is problematic

    the degree to which common morality can be said to support the 4 principles is questionable

    the content of the 4 principles is determined within a specific culture

    the four principles do not cover the whole moral domain

    the guidelines for specification and balancing are vogue.

  • 26

    The pluralism in bioethical approaches

    Legal context of the problem

    Empirical evidences in approaching an ethical

    problem

    Social sciences approaches

    Religious approaches

  • 27

    DECLARATION OF GENEVA Adopted by the 2nd General Assembly of the

    World Medical Association, Geneva, Switzerland, September 1948

    AT THE TIME OF BEING ADMITTED AS A MEMBER OF THE MEDICAL PROFESSION: I SOLEMNLY PLEDGE myself to consecrate my life to the service of humanity;

    I WILL GIVE to my teachers the respect and gratitude which is their due;

    I WILL PRACTICE my profession with conscience and dignity;

    THE HEALTH OF MY PATIENT will be my first consideration; I WILL RESPECT the secrets which are confided in me, even after the patient has died;

    I WILL MAINTAIN by all the means in my power, the honor and the noble traditions of the medical profession;

    MY COLLEAGUES will be my sisters and brothers;

    I WILL NOT PERMIT considerations of age, disease or disability, creed, ethnic origin, gender, nationality, political affiliation, race, sexual orientation, or social standing to intervene between my duty and my patient;

    I WILL MAINTAIN the utmost respect for human life from its beginning even under threat and I will not use my medical knowledge contrary to the laws of humanity;

    I MAKE THESE PROMISES solemnly, freely and upon my honor.
