First, there must be a moral code and moral justification to guide the physician in his actions. We learn as early as the Old Testament from Hebrew Scripture the value of life. In the Book of Genesis, God said Let us make man in our image and likeness (Genesis 1:26). We learn that God instilled the "breath of life" in man (Genesis 2:7). Because all human beings are created according to God's image and given the breath of life, we are called to respect the dignity of each human being.
Moses, the originator of the first five books of the Old Testament, lived before 1250 BC. God gave Moses the Ten Commandments as noted in the Book of Exodus, the one concerning life stated in a clear and direct manner:
The ancient writers of Greece were concerned with the principle of life. Plato considered the soul to be trapped within the body, happily released upon death. Aristotle saw the body and soul as one unit, the soul being the "life principle" of the body. Every physician who graduates from a medical school in the United States takes the Oath of Hippocrates, the Father of Medicine who lived in Greece from about 450-375 BC. The middle portion of the traditional Hippocratic Oath expressly forbids abortion and euthanasia:
Free and informed consent is required for medical treatments and procedures, except in an emergency situation when informed consent cannot be obtained and there is no indication that a reasonable patient would refuse consent to the treatment, as, for example, an unconscious trauma patient from a motor vehicle accident that presents to the emergency department.
Free and informed consent requires that the person or person's surrogate (or proxy) receive all reasonable information about the essential nature of the proposed treatment and its benefits; its risks, side-effects, consequences, and cost; and any reasonable and morally legitimate alternatives, including no treatment at all.
If a patient is incapable of making medical decisions, a proxy or surrogate, as an eldest son or a daughter who may be living with the parent and is in a position to best know the patient's wishes, is called upon to make treatment decisions. Should the proxy utilize the concept of substitute judgement or of best interest? Substitute judgement is a preference the patient has expressed in the past, whereas best interest decisions consider what treatment or lack of treatment would benefit the patient at that particular time. A balance of the two concepts often occurs in the clinical setting. For example, the family may remember the patient was adamant about not having gastric tube placement. The physician honors this request and the family and physician may decide it is in the best interest to give the patient intravenous fluids during the patient's final hours. Hopefully dialogue among the physician and family members can resolve the appropriate course of action.
The third principle is patient autonomy. Individual self-determination is highly valued in our American tradition, and rightly so. Patients should have the right to accept or refuse treatment, or allow the natural course of events to take place. It is important to remember that one must respect autonomy as long as we live in harmony with the first principle of our moral law and the sanctity of life.
The fourth principle of medical ethics is beneficence, or the act of helping others. Beneficence refers to the traditional role of the physician as the Good Samaritan. The compassionate physician performs acts of charity, kindness, and mercy; comes to the aid of the injured, the sick, and the dying; and relieves suffering. Natural or comfort care, the offering of food and water and the maintenance of body temperature and cleanliness for the dying elderly patient is a form of beneficence, as well as comforting the patient through a loving presence, palliation, and prayer. Jesus gave us the Parable of the Good Samaritan, as recorded in the Gospel of Luke:
But a Samaritan, as he journeyed, came to where he was; and when he saw him, he had compassion, and went to him and bound up his wounds, pouring on oil and wine; then he set him on his own beast and brought him to an inn, and took care of him. And the next day he took out two denarii and gave them to the innkeeper, saying, `Take care of him; and whatever more you spend, I will repay you when I come back.'
Which of these three, do you think, proved neighbor to the man who fell among the robbers?" He said, "The one who showed mercy on him." And Jesus said to him,"Go and do likewise."
Gospel of Luke 10:29-37
The sixth principle of medical ethics is justice. Justice means respecting the rights and dignity of each human being. The real purpose of civil law is to guarantee an ordered social coexistence in true justice, so that all may "lead a quiet and peacable life, godly and respectful in every way" (1 Timothy 2:2).
The physician must be fair to his patient, respect his rights as a person, and give the patient proper access to health care.
Today the principles of social justice often impact upon health care, as the corporate world has engulfed the profession of medicine. Scripture firmly supports the concepts of social justice, such as the New Testament Letters of St. Paul: in his First Letter to the Corinthians 3:8, he states that "every man shall receive his own reward according to his own labour."
The publication of Rerum Novarum on May 15, 1891 by Pope Leo XIII contributed greatly to improved treatment of workers during the Industrial Revolution. Pope John Paul II had a major impact in his call for social justice in the mistreatment of workers in Communist Poland, an event that ultimately led to the fall of the Iron Curtain. In his followup encyclical Centesimus Annus, published May 1, 1991, the Pope warned corporations against treating workers as "units of production" in their quest for profit.
Finally, the seventh principle of medical ethics is the physician, as a leader in the community, must be diligent to develop a virtuous character and exhibit moral integrity. The virtues are discussed below. We have the best role model - the great Physician, Jesus Christ!
