Spanish speakers make up 13.1% of the US population, and language barriers contribute to health disparities. Medical interpreters are essential for communication between patients with limited English proficiency (LEP) and their clinicians. However, there is a shortage of interpreters nationwide; free clinics, where a large majority of patients with LEP receive care, are especially affected by this shortage. Many medical schools are associated with a free clinic, and medical students who speak Spanish can help fill this gap. Loyola University Chicago Stritch School of Medicine, together with Interpreter Services at Loyola University Medical Center, created an interpreter certification program for medical students. Although there are challenges in certifying medical students as interpreters, doing so helps to build a workforce of well-trained, culturally competent physicians.
