The doctor-patient relationship is based on trust, respect and effective communication.
Medical ethics is the branch of applied ethics that studies the principles and values that should guide medical practice, with the aim of guaranteeing respectful, fair and responsible care for patients. This field addresses dilemmas such as confidentiality, informed consent, justice in the distribution of resources, and end-of-life decisions, seeking to balance individual rights and collective well-being.
Examples of medical ethics
Medical ethics is applied in specific situations that involve complex decisions. For example:
- Medical Confidentiality – Maintaining the privacy of patient information is a fundamental principle. This includes not sharing personal data without your consent, even under pressure from third parties;
- informed consent : doctors must clearly explain the procedures, their risks, benefits and alternatives, allowing the patient to decide autonomously whether to accept or reject the treatment;
- justice in health care : ensuring that health resources are available equitably, avoiding discrimination in health care based on gender, origin, socioeconomic status or any other factor;
- ethics in palliative care : deciding how to alleviate suffering in terminally ill patients without artificially prolonging their lives, respecting their wishes.
History of medical ethics
Medical ethics has a long history that has evolved with advances in medicine and social changes. It originated in ancient Greece with the Hippocratic Oath (5th century BC), where principles such as non-maleficence and confidentiality were established. During the Middle Ages, ethical approaches were based on religious values, such as compassion and charity.
In the 18th century, Thomas Percival wrote the first formal code of medical ethics, laying the foundations for modern deontology . The 20th century marked a turning point with documents such as the Nuremberg Code (1947), which emerged after the inhumane experiments carried out during World War II, and the Declaration of Helsinki (1964), which established international ethical guidelines for research in human beings.
Today, medical ethics faces new challenges, such as those posed by bioengineering, artificial intelligence, and end-of-life decisions.
End-of-life decisions are critical moments where medical ethics guide the patient's pursuit of well-being.
Importance of medical ethics
Medical ethics are essential to ensuring that healthcare is provided with respect and fairness . Its importance lies in the fact that it protects the dignity and rights of patients, ensuring that medical decisions are not made solely based on scientific or economic criteria.
In clinical practice, medical ethics fosters trust between patients and professionals , something essential for the success of any treatment. Furthermore, in the field of research, it serves to prevent abuses, such as the exploitation of vulnerable groups or the manipulation of results.
In a world where technologies advance rapidly, medical ethics provides a framework to address complex issues such as gene editing, access to high-cost treatments , and artificial intelligence in diagnosis. Without it, medicine could lose its human character and become a mere technical exercise.
Fundamental principles of medical ethics
Medical ethics is based on fundamental principles that guide professionals in making fair, responsible and respectful decisions towards patients. These principles form the basis of clinical practice and are constantly evolving to adapt to the challenges of the modern healthcare system.
Patient autonomy
The principle of autonomy recognizes the right of patients to make informed decisions about their health care. Doctors have an obligation to provide all necessary information in a clear and understandable manner , respecting the patient's ability to accept or reject treatments, even if these decisions contradict medical recommendations.
Charity
This principle implies that doctors must always act by prioritizing the interests of the patient, promoting their well-being and minimizing harm. This ranges from accurate diagnosis to the design of treatments that balance risks and benefits, always with a humanitarian approach.
Medical privacy
Confidentiality in therapy is essential to maintain trust between doctor and patient. Healthcare professionals are obliged to protect personal data and can only share it under ethically justified circumstances, such as emergencies or legal requirements.
Multiculturalism in healthcare
In a diverse society, professionals must be sensitive to cultural, religious, and social differences that may influence medical decisions. This principle encourages inclusive and respectful care, tailored to the individual needs of each patient.
Ethics in end-of-life care
End-of-life medical care raises complex ethical dilemmas involving respect for patient wishes, quality of life, and decisions about treatments that may prolong suffering.
Hospice care
Palliative care focuses on relieving pain and other symptoms, improving quality of life rather than seeking a cure. This ethical approach prioritizes the well-being of the patient, ensuring that they receive respectful and dignified care.
End of life decisions
End-of-life decisions include aspects such as withdrawal of life support, do-not-resuscitate (DNR) orders, and, in some countries, euthanasia or assisted suicide. These decisions must be based on the patient's values and wishes, always considering the current legal and ethical framework.
Right to die with dignity
The right to die poses an important ethical challenge. Some argue that allowing a patient to decide the time of death is an act of respect for their autonomy, while others believe that it goes against the medical principles of preserving life. This issue continues to be debated in many societies.
Ethics in medical research
Medical research is essential for the advancement of knowledge, but it must be conducted in accordance with strict ethical principles to protect participants and ensure the validity of the results.
Conflicts of interest
Researchers should avoid situations where personal or financial interests could influence their decisions. Transparency and ethical and legal regulations are essential to prevent conflicts that could compromise the ethics of the studies.
Clinical trials in vulnerable groups
Research on vulnerable populations, such as children, the elderly, or disadvantaged communities , requires special care. It is essential to ensure that these groups are not exploited and that they participate only if the potential benefits clearly outweigh the risks.
Use of animals in research
Although controversial, the use of animals remains common in medical research. This aspect requires an ethical balance that prioritizes the minimization of animal suffering and explores alternatives whenever possible.
Medical research must respect ethical principles to protect participants and advance knowledge in a responsible manner.
Ethics in medical specialties
The application of ethical principles varies by medical specialty, facing unique challenges in each area.
Ethics in psychiatry
Psychiatry faces dilemmas related to informed consent , especially in patients with compromised mental capacity. Additionally, the stigma associated with mental disorders poses challenges to ensuring that patients receive equitable and respectful care.
Ethics in dentistry
In dentistry, ethics is linked to the promotion of necessary treatments over unnecessary cosmetic procedures. Dentists should avoid practices that prioritize financial benefits over patient health.
Ethics in pediatric care
Pediatric care requires a particular ethical approach due to children's inability to make informed decisions. In these cases, doctors work with legal guardians, balancing the best interests of the child with respect for their emerging rights.
