Medical Ethics

The field of ethics examines the complex principles of right and wrong that influence nearly every aspect of modern medicine.

Ethical Considerations in Healthcare

There is hardly an area in medicine that doesn't have an ethical aspect. Key areas where ethical issues arise include:

  • End of life care: Should a patient receive nutrition? What about advance directives and resuscitation orders?
  • Abortion: When does life begin? Is it ethical to terminate a pregnancy with a birth defect?
  • Genetic and prenatal testing: What happens if you are a carrier of a defect? What if testing shows that your unborn baby has a defect?
  • Birth control: Should it be available to minors?
  • Stem cell research: Is it ethical to harvest embryonic stem cells to treat diseases?
  • Organ donation: Must a relative donate an organ to a sick relative?
  • Personal health information: Who has access to your records?
  • Patient rights: Do you have the right to refuse treatment?
  • Doctor-patient communication: When you talk with your doctor, is it ethical for her to withhold information from you or your family?

Frequently Asked Questions

Yes. Under the principle of patient autonomy and informed consent laws, any mentally competent adult has the legal and ethical right to refuse medical interventions, including life-sustaining treatments such as mechanical ventilation, cardiopulmonary resuscitation, artificial nutrition, and blood transfusions, even if that refusal will result in death.
hospital ethics committee is a multidisciplinary group comprising physicians, nurses, social workers, legal counsel, and community representatives that helps resolve ethical conflicts in patient care, such as end-of-life disputes or surrogate decision-making disagreements. Anyone involved in a patient's care—including the patient, family members, nurses, or physicians—can request an ethics consultation for non-binding guidance.
healthcare provider may breach confidentiality without patient consent when required by law or to prevent imminent, serious harm. Mandatory exceptions include reporting suspected child or elder abuse, notifying public health authorities about specific reportable communicable diseases, complying with court orders, and acting on a clear, credible threat of severe violence against an identifiable individual.
The four core principles are autonomy, beneficence, non-maleficence, and justice. Autonomy means respecting the competent patient's right to self-determination and decision-making. Beneficence requires clinicians to act in the best interest of the patient. Non-maleficence mandates doing no intentional harm. Justice requires the fair, equitable distribution of healthcare resources and equal treatment across diverse populations.
