Effective communication is essential for accurate diagnosis, informed consent, and patient safety. MCCQE ELOM objectives emphasize the physician’s responsibility to ensure clear, accurate, and confidential communication when language barriers exist. The best practice is to use a professional interpreter service (virtual or in-person) . Professional interpreters are trained to provide accurate translation, maintain confidentiality, and avoid introducing bias or omissions.

Using family members, community volunteers, or untrained staff (e.g., a laboratory technician) risks inaccuracies, breaches of confidentiality, and potential distortion of sensitive information. This is particularly important in adolescents, where confidential history (e.g., substance use, cardiac symptoms, sexual history) may be relevant. Simply speaking slowly or using simpler language does not overcome a true language barrier.

Professional interpreter services improve clinical outcomes, enhance patient understanding, and reduce medico-legal risk. Therefore, arranging a certified interpreter—either in person or via telephone/video—is the most appropriate approach.
