What should an interpreter explain when a patient prefers a family member to interpret?

When a patient prefers a family member to interpret, it is crucial for the interpreter to explain the importance of confidentiality and impartiality. Professional medical interpreters are trained to handle sensitive information in a way that protects the patient's privacy. Family members may not understand the full extent of what needs to be communicated and may unintentionally breach confidentiality, either by revealing information to others or by failing to convey the patient's words accurately due to personal biases or emotional involvement.

Furthermore, professional interpreters aim to remain impartial, ensuring that communication is clear and unbiased. Family members who interpret may have their own opinions or interests, which can interfere with the objectivity necessary for effective communication in a healthcare setting. Thus, emphasizing confidentiality and impartiality helps to clarify why a trained interpreter is often a better choice for ensuring that the patient's healthcare interactions are handled professionally and respectfully.
