ETHICAL CONCERNSEthics, A Branch of PhilosophyMany folks roll their eyes and change the subject when they hear the word ethics, viewing it as too controversial or too complex for discussion. Nonetheless, ethics is a significant concern of thinking, caring persons, especially healthcare providers such as physical therapists, physical therapy assistants, nurses, and physicians. Ethics is the a branch of philosophy concerned with the rightness or wrongness of human behavior and the goodness or badness of its effects. Because ethics assumes that people have the ability to make choices about their behavior, it has been the subject of philosophical discussion for centuries, generating an enormous body of literature. Those who study ethics divide these writings into three general categories: descriptive (characteristics), analytical (meta-ethics), and prescriptive (normative).
A teleological (consequential, utilitarian, situational) perspective affirms that the rightness or wrongness of an act is determined by the end results of an action. The term comes from the Greek teleos, meaning “end.” If the end result harms others, the act is considered wrong or bad. If the end result benefits others, the act is considered good or right. The central issue of this perspective is the principle of the “greatest good.” The utilitarian teachings of John Stuart Mill and the situation ethics of Joseph Fletcher maintain that end results and circumstances are essential factors in considering the rightness or wrongness of human behavior (Hamilton, 1996). Teleological theories foster morality by developing the capacity of humans to make choices. These theories reject fixed moral codes of conduct such as the biblical command “Thou shalt not kill” (Exodus 20:13). For example, a man is suffering with intractable pain caused by an incurable disorder. He begs his physician to give him enough pain medication to lessen his suffering, even though the drug dose may hasten his death. According to teleological perspective, the physician should provide the medication because the end result (relieving pain) is a greater good than keeping the man alive but suffering intractable pain. The deontological (nonconsequentialist) perspective fosters morality by teaching humans to accept and obey fixed laws. The term comes from the Greek deontos, meaning “duty to obey.” Immanuel Kant is the theorist most often identified with deontological ethics. He maintained that certain acts are inherently right or wrong, regardless of the situation or the end results. In deontological ethics, there are no exceptions or mitigating circumstances. According to this perspective, preserving the life of the man with intractable pain is a greater good than relieving his pain and hastening his death. The physician’s duty is to obey the commandment “Thou shalt not kill,” regardless of the situation or end result. Thus, the deontological perspective simplifies ethical decision making by removing the issue of mitigating circumstances. Concepts Related to EthicsBioethics is the application of ethics to matters of human life. As scientific knowledge expands and healthcare providers have greater control over disease, pain, life, and death, it is necessary to address issues of right and wrong behavior. Although some authors use the term morals to refer to human behavior and ethics to refer to formalized codes of conduct, both words mean the same thing. Ethics comes from the Greek word ethos and morals from the Latin word mores. In recent years, some politicians have substituted the word values for morality, however the word values has a much broader meaning. Values are treasured ideals and attributes, such as creativity, achievement, adventure, power, friendship, and belief systems. Understanding what you value brings purpose and clarity to life. Seeking such clarity was recognized by Socrates, who is credited with saying “An unexamined life is not worth living.” To help people examine their lives and clarify their values, Louis Raths (1979) suggested a seven-step process he called “values clarification,” as shown in Box 1.
Belief systems are organized patterns of thought regarding the origin, purpose, and place of humans in the universe. These systems seek to explain the mysteries of life and death, good and evil, health and illness. Typically, belief systems include an ethical code of conduct about how people should relate to the world and its inhabitants. Religions are schemes of thought and action that usually include belief systems, faith in a mystical power, devotional rituals, and organizational structures. Though some religions are centuries old, with myriad adherents, others are relatively new, with only a few followers. In the United States, when believers band together to perform charitable work they are given special protections and benefits. Ethical PrinciplesEthical principles are fundamental concepts by which people judge behavior. These principles help individuals make decisions and serve as criteria against which people gauge the rightness or wrongness of behavior. Laws are rules made by an authority with the power to enforce them. Although laws flow from ethical principles, they are limited to specific situations and codified by detailed language. Ethical principles are guiding ideals of conduct that speak to the spirit of a law rather than its letter. Throughout recorded history, leaders of world religions have taught an overarching ethical principle commonly known as the Golden Rule. It may be expressed in positive terms, “Do unto others as you would they do unto you,” or in negative terms, “Do not do unto others as you would not have them do unto you.” Some philosophers emphasize certain principles over others. For example, Kant held that duty was the central issue; Mills, the interest of all; Fletcher, love; Thiroux, human dignity; Nodding, care; and Gilligan, care and justice. A single, global principle for exemplary behavior is an attractive approach, but when people face real-life situations they seek more precise guidance. Over the years, five ethical principles have emerged as especially applicable to healthcare providers. They are: respect for human life and dignity, beneficence, autonomy, honesty, and justice. The Code of Ethics of the American Physical Therapy Association, described below, applies all five principles to practice. HUMAN LIFE AND DIGNITYRespect for human life and dignity is one of the most basic of ethical principles. It requires that “individuals be treated as unique and equal to every other individual and that special justification is required for interference with an individual’s own purposes, privacy, and behavior” (Rawls, 1971). This principle calls for respect for the life, freedom, and privacy of all humans. When applied to practice, respect for human rights and dignity means that physical therapists:
BENEFICENCEBeneficence means doing good to benefit others. Although some writers separate beneficence (doing good) from nonmaleficence (not doing harm), Frankena (1973) suggested the ethical principle of beneficence is a continuum, from a neutral not harming, to a positive doing good, that is, not inflicting harm . . . preventing harm . . . removing harm . . . promoting and doing good. At a minimum, beneficence means maintaining professional competence. However, it also means acting in ways that demonstrate care and nurturance. When applied to practice, beneficence means that physical therapists:
AUTONOMYAutonomy is the right of self-determination, independence, and freedom. It is the personal right of individuals to absorb information, comprehend it, make a choice, and carry out that choice. Physical therapists carry out the principle of autonomy by providing information to clients, assisting them to understand the information, and helping them make decisions based on accurate scientific information. When applied to practice, autonomy means that physical therapists:
HONESTY (TRUTHFULNESS, FIDELITY)Honesty means truthfulness in word and deed. Even when needing to convey unwelcome information to clients about their illness or treatment options, physical therapists do so truthfully, with compassion, only withholding information when the client is a minor child or an adult under legal guardianship. Dishonesty and deceit are especially odious when they involve theft of pain-relieving drugs or devices. Honesty means absolute truthfulness regarding professional credentials and financial matters, never charging for unearned services or accepting commissions, discounts, or gratuities for covert gain. It means obeying both the spirit and the letter of the law. When applied to practice, honesty means that physical therapists:
JUSTICEJustice implies fairness and equality. It requires impartial treatment of clients. Like other ethical principles, justice is based on respect for human life and dignity. The historic image of justice is a blindfolded woman with a scale, weighing an issue on the basis of objective evidence and judicial precepts. Justice means that scarce resources will be distributed equally, using the same criteria for everyone. When applied to practice, justice means that physical therapists:
Ethical DilemmasA dilemma is a perplexing problem that requires a choice between conflicting alternatives. An ethical dilemma is a moral problem that requires a choice between two or more opposite actions, each of which is based on an ethical principle. For example, a physical therapist must decide whether to honor the ethical principle of honesty and disclose the unlikely value of a proposed treatment to relieve pain or to honor the principle of beneficence and withhold information in order to give the client hope. Resolution of ethical dilemmas requires careful evaluation of all the facts of the case, including applicable laws, consultation with all concerned parties, and appraisal of the decision makers’ ethical stance (whether it is teleological, by which we consider end results, or deontological, by which we obey fixed laws). Nowadays, ethical dilemmas in healthcare facilities arise more frequently because modern medicine can keep hearts and lungs functioning when brains have lost the ability to think. To help resolve these perplexing issues, many institutions appoint ethics committees made up of healthcare professionals, ethicists, lawyers, and clergy. The task of ethics committees is to help decision makers resolve ethical dilemmas. Often these committees use an ethical decision making process such as the following:
To reduce the number and complexity of ethical dilemmas, and in support of the ethical principle of autonomy, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) recommends that all adults discuss their wishes regarding extraordinary treatment measures with their families and sign a legal document, called an advance healthcare directive, appointing someone to make healthcare decisions in their stead if they should become incapacitated (JCAHO, 2003). Codes of EthicsCodes of ethics are formal statements that set standards of ethical behavior for a group of people. In fact, one of the hallmarks of a profession is that its members subscribe to a code of ethics. The Code of Ethics of the American Physical Therapy Association (APTA) makes explicit the values and standards of the profession, providing guidance to carry out the professional responsibilities of physical therapists (Box 2).
LEGAL AND PROFESSIONAL RESPONSIBILITYAlthough physical therapists (PT) and physical therapist assistants (PTA) gain professional certification from their national organization, they must be licensed to practice under state laws. For that reason, both PTs and PTAs need to understand the relationship of ethics to law, the basis of United States law, sources and types of laws, some salient legal concepts, standards and guides for professional conduct, and application of ethics and law to the practice of physical therapy. Ethics and Law in the United StatesLaws flow from ethical principles, but are limited to specific situations and codified by detailed language. They are rules of behavior made by an authority with power to enforce them. As such, they change with time. In the United States, law is based on the old English system where the monarch held supreme power over the land and its people, acting according to “divine right.” Decisions of the monarch became the law of the land and were known as common or case law. These case-by-case decisions set precedent and shaped future laws. In the United States, the Constitution is the supreme law of the land, filling the role once held by the monarch. The first ten amendments to the Constitution, the so-called Bill of Rights, place restrictions on the power of government and establish specific individual freedoms, such as the right to free speech and assembly. When people believe they have been denied any of these rights, they can seek redress in the courts. The U.S. Constitution established three separate branches of government within the federal system: executive, legislative, and judicial. The Constitution grants specific powers to the federal government, called express powers. Under the Tenth Amendment, all other powers are retained by the states, including licensure of healthcare professionals such as physical therapists. In the states, the division of power mirrors that of the federal government. The judicial branch interprets the law and adjudicates disputes, fulfilling its purpose by administering justice without partiality. The legislative branch make laws on behalf of the people. The executive branch administers and enforces the laws, using the police power of the state. Table 1 summarizes the sources of law in the United States, and Table 2 summarizes the types of law.
Federal Statutory IssuesHistorically, healthcare regulation has been the province of the states. However, in recent years, the federal government has become increasingly involved. Three pieces of legislation are of particular concern to physical therapy, namely, the Social Security Amendments of 1965, establishing Medicare and Medicaid, the Americans with Disabilities Act of 1995, and the Health Insurance Portability and Accountability Act of 1996. SOCIAL SECURITY AMENDMENTS OF 1965Medicaid and Medicare provide healthcare for the indigent, the disabled, and people over 65 years of age. Medicaid is a healthcare plan that pays for intermediate and skilled care for indigent people. Medicare is a insurance program that pays for skilled care only (eg, nursing, physical therapy, occupational therapy). Medicare has two parts: hospital insurance and medical insurance. Part A, the hospital insurance, helps pay for inpatient hospital care and some follow-up care such as home health services and hospice care. Part B, the medical insurance, helps pay for such services as physician, nurse practitioner, and physical therapy services, laboratory tests, diagnostic x-ray and therapy, preventive screening tests, surgical supplies, casts, splints, kidney dialysis, diabetic supplies, and more. The “original” or basic plan covers only a small portion of the cost, thus individuals must buy additional insurance sometimes known as “Medigap” insurance (USDHHS, 2005). AMERICANS WITH DISABILITIES ACT OF 1995The Americans with Disabilities Act (ADA) is a broad-reaching civil rights statute. It protects the rights of people with a variety of ailments, including persons infected with human immunodeficiency virus (HIV) and those with respiratory and musculoskeletal disorders. Its provisions include many issues of special concern to physical therapists, such as access to public buildings, equal protection of disabled persons, and nondiscrimination in employment.

| CASE 1 | Sam Bruno, PT, the owner of City Physical Therapy Center, placed an advertisement in the local newspaper claiming to treat people without the need for “a time-consuming, individualized examination.” Sam is violating a specific principle of the Guide for Professional Conduct, namely 8.2.B, which requires public emphasis on individualized examination. Discussion question: In addition to identifying the violated principle, what action should Sam’s professional colleague take, if any? Suggested answer: As a colleague, you should address Sam about his unethical behavior. If he does not change his ad, then discuss the issue with the local APTA chapter. |
| CASE 2 | The neighbor of Molly Soft, PTA, repeatedly complains about her painful neck and asks Molly to treat her. At first Molly refuses, but eventually she gives in and performs four manual therapy treatments on the neighbor’s cervical spine. At first the treatments help, but after the fourth one, the neighbor complains of increased neck pain. Molly violated a specific standard in the Guide for Conduct of the PTA, namely Standard 3.1.A, which requires that PTAs work under the direct supervision of a PT. Discussion question: What action should Molly take? Suggested answer: Molly should refer her neighbor to a physician for examination and treatment. She should also inform the neighbor that, as a PTA, Molly is bound by ethical standards and licensure laws and she cannot treat the neighbor without the supervision of a PT. Molly has put both her neighbor and herself at risk. |
| CASE 3 | Joe Peal, PT, an employee of the local home health agency, feels a strong sexual attraction for the daughter of one of his clients. He is considering asking her for a date and shares his thoughts and feelings with a colleague. The specific principle of the Guide for Professional Conduct is 2.1.B, which prohibits a PT from exploiting any aspect of a client relationship. Discussion question: If you were Joe’s colleague, what would you advise him to do? Suggested answer: Joe should ask his supervisor to assign another PT to the client and terminate his PT/client relationship before pursuing an association with the daughter. |
| CASE 4 | A PT just started her own business and is heavily in debt. She does not have a full caseload, but says she does not want to “start a precedent” by providing pro bono services to clients. A specific principle of the Guide for Professional Conduct that speaks to this issue is 10.1, which recommends that PTs provide reduced- or no-fee services when possible. Discussion question: What ethical principle could you use to appeal to your colleague? Suggested answer: The ethical principle of beneficence, taking an action to benefit others. |
| CASE 5 | A 33-year-old client is admitted who has severe systemic cellulitis, with weeping sores covering her legs and lower torso. Pam Newsom, a new PT graduate, is asked to administer wound care, alternating with a group of experienced PTs. Although Pam received wound care training during her schooling and knows that the treatment is within a PT’s scope of practice, she is nevertheless reluctant. Pam has never done wound care before and does not feel she has the experience or competence to treat this client. The specific principle of the Guide for Professional Conduct that speaks to this issue is 5.1, which asserts that a physical therapist shall practice within the scope of his/her competence and commensurate with his/her level of education, training, and experience. Discussion question: What should Pam do? Suggested answer: Pam should not perform procedures she does not know how to do. She should communicate immediately with her supervisor. |
