The ethics of pediatric health care have changed radically in the past 50 years. “History,” they say, “is written by the victors.” So, if you are not careful, you will only get part of the story. Clinical ethicists learn to seek out, involve, and empower the voices of all stakeholders. To fully appreciate how much things have changed, you must learn more than one side of the story. Indeed, piecing together the history of medical ethics reminds me of the Indian story of five blind men describing an elephant, in which each can only describe a part of an ultimately much bigger animal.
If you ask philosophers about the history of medical ethics, they will point to events 50 years ago as the beginning of the modern era. In the 1960s, physicians tended to be paternalistic authoritarians. Some considered it best not to even tell a patient that he had cancer. There was minimal patient education provided. Medications were prescribed as orders for the patient to follow. Medical research had harmed volunteers, and new protections were needed.
The 1970s brought change, with the courts laying out new rules for informed consent in cases like Canterbury v Spence (1972). For over 5 years, a national commission studied the research scandals, as in the Tuskegee Syphilis Study. In 1978, it produced the landmark document known as the Belmont Report.1 That report formed the basis for the modern institutional review board (IRB). Another landmark publication was the first edition of Principles of Biomedical Ethics by Tom L. Beauchamp and James F. Childress in 1979, which provided the four principles of the Georgetown Mantra of Bioethics: autonomy, beneficence, nonmaleficence, and justice. With time, autonomy became the first among equals of those four principles.
In 1995, the American Academy of Pediatrics Section on Bioethics emphasized the importance of obtaining the child’s assent in addition to the parent’s consent.2 Most states have passed laws permitting minors to give consent for treatment for pregnancy, sexually transmitted diseases, drug addiction, and mental health care.
Technology alters ethics
At the same time, technology has been changing medicine. New life sustaining technologies in the 1960s – such as dialysis and ventilators – created new issues of extreme financial cost, allocation of scarce resources, and even the existential question of when life ends. In 1968, an ad hoc committee at Harvard created criteria for what is colloquially called “brain death.”3 Many landmark legal cases further developed the ethics of end-of-life care.
Meanwhile, pediatric oncologists began a new way of caring for children with cancer. They collaborated on a national level. Each newly diagnosed child was entered into a registry and treated according to a national protocol that was updated every few years. This blurred the distinction between experimental and clinical care. But, it yielded results. Within a couple decades, acute leukemia went from few survivors at 1 year after diagnosis to 95% becoming long term survivors of more than 5 years. With that success and new research always promising hope, the pediatric oncologist’s ethical dilemma became when to palliate rather than seek a cure.
The boundaries were even less clear at the beginning of life. Technological advances in ventilators, improvements in nursing care by neonatal intensive care unit nurses, and the whole new subspecialty of neonatology progressively lowered the gestational age for survival. The distinction between clinical care and experimental care was again blurry as neonatologists sought to overcome previously unknown complications, like retinopathy of prematurity resulting from too much oxygen and bronchopulmonary dysplasia from the ventilator. Many babies survived with profound physical and neurological compromise. The ethical dilemmas were continuously present.
Some pediatricians will claim that medical ethics is driven primarily by advances in technology, not law. Perhaps the most telling point for this has been that, when clinical ethicists specializing in pediatric ethics get together at national meetings, about half are neonatologists and a quarter are pediatric ICU physicians. These physicians have acquired expertise in ethics as a survival mechanism for the daily challenges presented by new technology.
Change in the status of children
There is more to the story than philosophy, law, and technology. Pediatric ethics has been profoundly impacted by a change in the status of the children. One change from 50 years ago has been the social response to child abuse.4 Norms changed. Before, fathers pretty much could raise their children any way they saw fit, including corporal punishment. Neighbors didn’t intervene. The proverb was “spare the rod and spoil the child,” but abuse was not motivated by discipline. It was cruel, authoritarian, and demeaning. The landmark article describing the Battered Child Syndrome was published in 1962.5 By 1967, the local Society for the Prevention of Cruelty to Children had become nearly obsolete, but understaffed local government agencies were just beginning to respond. In 1974, federal action produced the Child Abuse Prevention and Treatment Act.6 Medical personnel became mandatory reporters, developed expertise, and, in 2009, child abuse became a boarded subspecialty in pediatrics.
There also has been a huge change in the status of children with mental and physical disabilities. Fifty years ago, it was the short bus and the County School for Retarded Children.
Then, in 1971, a documentary “Who Should Survive?” explored the ethical decision making for babies with birth defects.7 The harms of institutionalization became recognized. The benefits of early intervention and special education have been established. Support for an Individual Education Plan has progressed through successive laws beginning in 1975 until the Individuals with Disabilities Education Improvement Act of 2004.
This is just another example of how ethics develops from a philosophical ideal to a change in social status, followed by consciousness raising, civil rights legislation, enabling legislation, funding, and program development and implementation.
It takes a village of philosophers, activists, lawyers, legislators, physicians, and other experts to implement ethics. There are also countervailing forces. The mainstreaming of children with disabilities is one factor in the movement of children into private schools and the pressure for a voucher system, as advocated by the new Secretary of Education, Betty DeVos.
There also has been a change in the status of children as future providers. Historically, children were relied upon to provide for the parents in their old age. With decreases in infant mortality, the availability of birth control, and legalized abortions, smaller families became the social norm. Worldwide, there has been a marked drop in fertility rates in developed nations. Governmental programs such as Social Security, particularly with the introduction of Medicare in 1965, meant that the elderly were less dependent on their descendants. China found that acceptance of the One Child policy was heavily dependent on convincing parents that the State would provide for them in their old age. The modern political state has assumed duties previously performed by the family.
More recent changes
Pediatric health care is strongly impacted by public health measures. Infant mortality has been reduced by improved nutrition and public health, not medication and surgery. Mass immunization programs were viewed as an appropriate function of civic government.
The introduction of polio vaccine in the 1950s made a large impact. Families lined up at any opportunity to get the vaccine. Polio went from hundreds of thousands of cases of paralysis each summer down to zero cases of wild polio transmitted within the western hemisphere. Measles cases went from 450,000 cases a year in the early 1960s down to zero, until a fraudulent link to autism led to a significant number of parents not immunizing their children. Vaccine refusal, previously a rare ethical issue related to religious liberty, became corrupted by efforts at boutique medicine and alternative facts. In modern America, the ethics of individualism and personal rights have eclipsed civic responsibility. With herd immunity compromised, a blip up to 100 cases of measles per year was histrionically described as a huge epidemic. That spin shows ignorance of the historical record, but the risk was enough for the liberal state of California in 2015 to ban philosophical exemptions to vaccination with one of the strictest state laws in the nation.
Ethics is about values. So, as I look at the changes over 50 years, the areas that have failed to make progress are illuminating. Mental health care for children has not made the same progress achieved with vaccines and cancer therapy. My most recent clinical ethics case involved a teenager who had made a suicidal gesture by taking a handful of pills. The nurses were caught between caring for their patient and meeting the demands of an upset, authoritarian parent in a world where customer satisfaction is critical. I spent much of the night exploring hospital policy and state law. I solicited and listened to widely disparate interpretations of law, medical ethics, and hospital policy from the floor nurse, the nursing supervisor, the nursing staff on the adult inpatient psychiatric unit, three ED docs, a social worker, a government agency, and a judge’s representative. The physician of 1967 was captain of the ship and would not recognize the chaotic teamwork of modern medicine. The exercise showed me how little progress we have made in mental health care for adolescents during my 25 years of practice.
It also reminded me that I have the luxury to debate ethical minutia like vaccine hesitancy and adolescent consent in a world with Syrian refugee camps and starvation in South Sudan. Mahatma Gandhi said, “There are people in the world so hungry that God cannot appear to them except in the form of bread.” That, unfortunately, has not changed in 50 years.
