Which ethical principle requires medical interpreters to maintain confidentiality?

The principle of confidentiality is fundamental in the field of medical interpreting, as it underscores the expectation that interpreters will keep all patient information private and secure. This principle ensures that patients feel safe sharing personal and sensitive information with healthcare providers, knowing that their privacy will be respected. Maintaining confidentiality is not only an ethical obligation but also a legal requirement in many regions, protected by laws such as HIPAA (Health Insurance Portability and Accountability Act) in the United States.

When interpreters adhere to this principle, they help to foster trust between the patient and the healthcare system, which is essential for effective communication and quality care. Breaching confidentiality can have serious implications for the patient’s health and well-being, as well as for the interpreter's professional standing.

The other options pertain to different ethical considerations within medical interpreting. The principle of accuracy focuses on the need for interpreters to convey messages faithfully and without distortion, while impartiality pertains to remaining neutral and not letting personal biases influence the interpretation. The principle of advocacy involves supporting the patient’s needs but does not directly relate to the aspect of maintaining privacy. Therefore, the principle of confidentiality is the one specifically associated with the obligation to protect patient information.
