Chapter 107 Ethical Issues in Child Neurology
Introduction
The “task” of ethics in general is to understand how human beings should behave in regard to other persons and to society [Slote, 1995] or to understand what is right and what is wrong. The philosophical study of ethics is as old as civilization itself and parallels the growth and development of human society. Morality is understood as the set of generally accepted rules and guidelines for acceptable conduct in society. These social conventions about what is right and wrong constitute the “common morality” [Beauchamp and Childress, 2001]. Philosophical ethics can be thought of as the attempt to develop a rational basis for morality. Although ethics (as a form of philosophy) strives for universal truth, it is inextricably linked to the realities of the human societies whose morality it seeks to understand [Slote, 1995]. Distinguishing between “moral” and “ethical” behavior is often difficult [Bernat, 2008]. Perhaps moral behavior may be thought of as a personal attempt to conduct one’s life in conformity with the common morality, whereas ethical behavior may be thought of as a more theoretical or rational attempt to apply philosophical thinking to what is right and wrong. In other words, ethics is a systematic attempt to understand how to live and act morally in a social context.
Ethics addresses all aspects of human behavior. Bioethics considers the interaction between biology and ethics. It is defined as “the systematic study of the moral dimensions of the life sciences and health care,” and includes consideration of “the health-related and science-related moral issues in the areas of public health, environmental health, population ethics and animal care” [Reich, 1995]. Clinical ethics is a subcategory of bioethics that refers to the day-to-day moral decision-making of those caring for patients [Callahan, 1995]. More specifically, clinical ethics refers to the identification, analysis, and resolution of moral problems that arise in the care of a particular patient [Jonsen et al., 2010]. Medical ethics is a subcategory of clinical ethics that refers to the moral behavior of physicians (and is thus distinguishable from nursing ethics, social work ethics, and pastoral ethics).
Neuroethics is a concept that cuts across most of these distinctions [Illes, 2005]. As an area of bioethics, it considers the interaction between the neurosciences and ethics in all of the same areas of study as for bioethics, noted previously [Pfaff, 1983]. As a clinical discipline, it addresses the care of patients with neurologic disorders. As an area of medical ethics, it refers most directly to the moral behavior of neurologists and neurosurgeons. Thus, child neurologists interested in ethics need to be knowledgeable about the general approaches to ethics, the emerging scope of bioethics, and the more specific approaches to ethics in medicine, nursing, and other health-related disciplines.
Although many articles and books have been published on ethical topics of interest to child neurologists, few provide a systematic approach to ethics in child neurology. A recent collection of articles covered a number of important topics [Shevell, 2002a], and a casebook presented a number of illustrative cases whose analyses illuminate many of the important ethical issues in child neurology [Freeman and McDonnell, 2001]. The best general, systematic resource on ethics in neurology is the classic text by Bernat [2008], but it mainly covers topics of interest in adult neurology. A recent collection of essays on pediatric bioethics, edited by a child neurologist, covered a number of topics of interest to child neurologists [Miller, 2010]. This chapter follows the general structure of Bernat’s book and seeks to apply its concepts specifically to the area of pediatric neurology. The goal of the chapter is to provide child neurologists interested in ethics with the tools they need to identify, analyze, and resolve moral problems they may encounter in the care of children and adolescents with neurologic disorders.
Theoretical Approaches to Ethics
Philosophy may be a search for truth, but the fact is that there is no one, true, universal approach to ethics. Physicians who want to act ethically should be aware of the several major ethical theories that compete for attention in contemporary medical practice. Two ethical theories in particular dominate thinking in Western philosophy. Utilitarianism is derived from the writings of Jeremy Bentham [Bentham, 1982] and John Stuart Mill [Mill, 1971]. Deontology is derived mainly from the writings of Immanuel Kant [Kant, 1959]. Elements of both theories persist in modern ethical approaches to clinical problems, usually in somewhat modified form. Most physicians will find themselves using utilitarian thinking on some occasions and deontologic thinking on other occasions, or using some combination of both when it is necessary to resolve an ethical dilemma in clinical practice.
Utilitarianism
The essence of utilitarian theory is the idea that the morality of an action is determined mainly by its consequences: the morally right action is the one that produces the best result [Beauchamp and Childress, 2001]. Of course, the result of an action may be quite complex. An action that helps one person may harm another person. Withdrawing support from a child in a vegetative state undoubtedly harms the child, since it results in the child’s death, but the action may help the family grieve and may allow society to use limited medical resources to help other patients. The utility principle states that one should act to produce the best overall balance of positive and negative consequences of the act. This idea is embedded in the concept of balancing risks and benefits to achieve the best overall result.
Utilitarian thinking is almost intuitive in many aspects of ordinary life. Understanding this form of thinking is important because it may help avoid the potential pitfalls that can result from uncritical application of the theory. Perhaps the most familiar situation is the use of utilitarian theory to justify the killing of defective newborns [Kuhse and Singer, 1985]. Although theoretically logical, such arguments are morally repugnant to persons who apply a different moral standard based on some other approach to ethics. Another problem with utilitarian theory is its failure to protect minorities, which results from its emphasis on producing the most good for the majority. The needs of children with rare neurologic disorders can be overlooked if utilitarian thinking allocates scarce medical resources primarily to children with more common disorders.
Deontology
Deontologic theory is based on the importance of “deon,” or duty. Duty is based more on the intentions that lead a person to act than on the outcomes or consequences of the action. Utilitarian thinking is mostly situational and depends on the specific aspects of a given situation; deontologic thinking strives to be more universal and to emphasize decisions that would apply in all relevant situations. Thus, Kant’s categorical imperative states that we should act only in a way that is consistent with a universal law or obligation [Kant, 1959]. Using people as means to an end implies that different actions (or reactions) are needed, depending on the end or outcome that is desired; therefore, the actions are not universally applicable. For this reason, deontologic thinking stipulates that we should treat all people as “ends” and not as means to an end. This could cause problems in thinking about the morality of organ transplantation if the organ donor is thought of only as a means to the end of survival for the recipient. Clearly, deontologic thinking imposes a duty to respect the rights and value of the donor as much as those of the recipient because anyone could be either a donor or a recipient.
Common Morality and Natural Law
What are the universal rules that spring from deontologic thinking? Most Western philosophers would argue that these rules can be derived from the application of reason – from rational, logical thinking about the nature of human existence. The general argument is that “all rational persons would agree that these rules are essential to govern and guide the moral actions of individuals in a cohesive society” [Beauchamp and Childress, 2001]. Beauchamp and Childress [2001] describe the “common morality” as socially approved norms of human conduct that form the basis of ethical theory. This common-sense understanding of what is needed for individuals to behave in society is not derived from theory, but rather forms the basis for potentially competing theories.
Natural law theory is an ancient approach to deriving universal rules through the application of reason [Simon, 1992]. For Thomas Aquinas, natural law sprang from man’s participation in God’s eternal law and was brought into being by the application to action of human intelligence and reasoning [May, 1994]. This application leads first to the principle that all things desire that which is good; therefore, good is to be pursued and evil is to be avoided. Good things are those to which man has a natural inclination, such as life (existence), social interaction, family life, and civil government. To pursue these good things, one should act fairly, love God, and love other persons. Secondary precepts or rules (such as the Ten Commandments) follow from these basic principles.
Secular interpretations of natural law are as old as Aristotle and are still used in some forms of legal theory. Bernard Gert [2002] defined two sets of rules that he believed all rational persons would accept as natural and essential, without relying explicitly on natural law theory. Many of his rules are in fact similar to the Ten Commandments. Gert also emphasized that the rules are not absolute and that violations may be considered in specific circumstances. Beauchamp and Childress [2001] do not define any specific rules as part of their common morality, but they do define four principles that are not absolute and that need to be specified based on actual circumstances. None the less, their four principles may be seen to correlate with the precepts of natural law:
Principlism
Principlism is an approach to ethical problems that is based on the application of the four principles of beneficence, nonmaleficence, justice, and autonomy. It is more of a practical guide than an abstract theory, and it has found widespread acceptance in a variety of settings [Beauchamp and Childress, 2001]. It was adopted explicitly in the Belmont Report, which forms the foundation for research ethics in the United States [Belmont Report, 1979]. Although principlism is perhaps the best-known approach to clinical ethical problems, it is by no means the only approach. Understanding principlism is necessary to consider these alternative systems.
The principle of beneficence encourages physicians to do good or to act in the best interest of the patient whenever possible. This principle can also be interpreted to suggest that physicians should seek to promote an optimal quality of life or satisfaction with life. Considerable debate exists about how to measure quality of life [Bowling, 2004; Nordenfelt, 1994; Nussbaum and Sen, 1993; Schalock, 1996]. Objective measures are based on the judgments of others, whereas subjective measures are based on the opinions of the patient about what constitutes a satisfying life. In general, preference is given to subjective judgments when they can be known.
The principle of nonmaleficence encourages physicians to avoid doing harm to patients and dates back to Hippocrates. It is related logically to the principle of beneficence. Both principles are considered when physicians attempt to strike a balance between providing a benefit for the patient (doing good) and not imposing a burden (avoiding harm). This balance may become especially problematic when the same action could produce a good, or desired, effect, as well as a bad, or undesired, effect. The classic example is prescription of sufficient medicine to reduce pain while knowing that it may also cause the patient to stop breathing. This problem is known as the “situation of double effect” [Beauchamp and Childress, 2001]. In Catholic moral theory (which contains the most explicit analysis of such situations), an action that causes double effects is morally justifiable only if it meets all of the following criteria:
The principle of justice requires that equals be treated equally, but the basis for an equal distribution of resources may be arguable. Should resources be distributed according to need, effort, merit, contribution to society, or some other factor? Utilitarian, libertarian, communitarian, and egalitarian approaches have been proposed to answer this question [Beauchamp and Childress, 2001]. Rawls [1971] suggests that resources should be distributed to ameliorate the effects of life’s natural and social lotteries. It may be simply bad luck (“losing the lottery”) that a child is born with a disabling condition or is born into poverty. If the child is not responsible for this condition, then society should act to remedy the situation. According to this rule, unfair situations would presumably have priority over merely unfortunate situations. How many resources should be provided to those who have been unfairly deprived? The limits of this redistribution policy may be the extent to which it disables or impoverishes the rest of society [Veatch, 1986].
Jonsen et al. [2010] suggest that ethical issues can be analyzed by asking the following four questions (which are, in fact, practical applications of the four principles discussed previously):
Virtue or Character Ethics
The catalog of virtues is not exhaustive and varies from one writer to another. Pellegrino and Thomasma [1993] suggest eight virtues that are necessary for sound medical practice:
Ethics of Care
Care-based ethical thinking is prominent in nursing practice but may be somewhat unfamiliar to physicians. It arose as somewhat of an alternative to deontologic, rule-based thinking that depends on adherence to more or less rigid principles. It also arose from feminist research studies comparing male and female approaches to ethical dilemmas. Gilligan [1982] found that males were more likely to look for rules to follow and to insist on adherence to these rules. Females were more likely to look for some situation-based way to resolve a dilemma, taking into consideration the person’s feelings and significant relationships [Gilligan, 1982]. This “feminine” way is not exclusively reserved for women (or for nurses), of course. Rather, it provides an alternative and perhaps more subjective way to evaluate an ethical problem that is especially relevant when a rule-based approach seems to be inappropriate or unhelpful [Held, 2006; Kuhse, 1997; Taylor and Watson, 1989].
Casuistry
Casuistry, or case-based ethics, is another alternative to utilitarian or rule-based ethical approaches [Jonsen and Toulmin, 1988]. It rejects the very idea of a “moral calculus” that can be analyzed impartially, based on abstract concepts. Instead of a “top-down” approach, based on pure theory, it takes a “bottom-up” approach, based on the particularity of specific cases. Casuistry looks at specific cases and emphasizes points of agreement about those cases. It recognizes that moral intuition may be more important than adherence to principles. It is common knowledge that members of hospital ethics committees often agree on what needs to be done but cannot always say with clarity why they feel that way (or what ethical theory they relied on to make a particular judgment). This moral intuition may also reflect the influence of the “common morality” described previously. By looking at the particularities of a specific case, casuistry is also sensitive to contextual influences and individual differences.
Spirituality
Spirituality is variously defined, but it can be understood as a belief system that focuses on intangible elements that impart vitality and meaning to one’s life [Koenig, 2002]. Because it is based on beliefs, or faith statements, it is not provable through logical argument. Spirituality in medicine is often based on religious beliefs [Sulmasy, 1997], but it need not be. As an expression of ultimate concern, it reflects the elements of our lives that are the most important and make life worth living. Most people have some spiritual beliefs that become prominent when their health is threatened; yet these beliefs are often not considered by physicians and other health-care providers. Physicians may anticipate that patients would have certain beliefs based on knowledge of their religious background [Numbers and Amundsen, 1998], but individual differences exist, even within a religious tradition. A more direct understanding of the patient’s spirituality would be preferable.
One approach to understanding the patient’s spirituality is the “three ways of looking” [Coulter, 2001]. The first look is to see the person subjectively as an individual human being. Compassion requires distance and objectivity [Pellegrino and Thomasma, 1993
