How should informed consent be handled when a language barrier exists?

• A. Have a family member translate for the patient.
• B. Use a qualified interpreter; ensure comprehension; avoid relying on family members.
• C. Have the patient sign a form in English without explanation.
• D. Postpone treatment indefinitely until English proficiency is achieved.

Answer: (B)

When there’s a language barrier, informed consent hinges on the patient truly understanding what they are agreeing to, so a qualified interpreter should be used to translate all information about the procedure, risks, benefits, and alternatives, with the patient’s comprehension verified before they decide. The interpreter helps ensure accurate communication and often supports a teach-back approach so the patient can confirm understanding. Relying on a family member for translation can lead to miscommunication, incomplete information, confidentiality breaches, and potential bias in the patient’s decision, so it should be avoided. A form signed in English without proper explanation does not fulfill informed consent, and postponing treatment is not appropriate if interpreter services are available. Provide translated materials as needed and document the use of interpreter services.
