Medical ethics brings helping patients into contact with informed consent, confidentiality, professional duty, and fair access. A beneficial intervention can still violate a patient’s authority over their body. Decisions about a system’s resources also differ from decisions made within a particular clinician–patient relationship.
Medical ethics brings together care for a particular patient, consent, fair allocation, and the institutional conditions of trust. These reasons can conflict. A beneficial treatment does not automatically authorize imposing it, while respect for choice requires meaningful information and support. Scarcity introduces further questions about which needs have priority. Separating the patient’s authority from the institution’s allocation duties helps explain why one simple principle may not resolve an entire clinical situation.
