More than 25 million Americans have limited English-language proficiency (LEP) according to the U.S. Census Bureau. This population experiences challenges accessing health care and is least likely to receive preventive health care, including screening mammogram. In a setting where the breast radiologist does not speak the language of their patient, using certified medical interpreter services is fundamental. Medical interpreter use is associated with improved clinical care and patient satisfaction and can potentially increase adherence to screening mammograms and follow-up in patients with LEP. Title VI of the Civil Rights Act requires interpreter services for patients with LEP who are receiving federal financial assistance. Failure to provide interpretative services when necessary is considered discriminatory and illegal. The use of untrained medical interpreters, including ad hoc interpreters (eg, family, friends, or untrained staff), is associated with more medical errors, violation of confidentiality, and poor health outcomes. Types of medical interpretation services available to address language barriers include in-person interpretation, telephone and video remote interpretation, and qualified bilingual staff. Proper training and certification of medical interpreters is essential to prevent misinterpretations and ensure patient safety. When using an interpreter service, speak to and maintain eye contact with the patient, address the patient directly and seat the interpreter next to or slightly behind the patient, use visual aids whenever possible, and have the patient repeat the information to verify comprehension. Breast radiologists can address disparities in breast cancer screening and treatment by promoting effective communication.
