Language barriers still cost the U.S. healthcare system an estimated $1.1 billion every year, and patients with limited English proficiency face 2.1 times higher odds of receiving inadequate care. At the same time, adoption is uneven as only 21% of hospitals report using machine translation for patient-facing materials and 48% of language-access leaders say they rely on informal interpretation at least occasionally. These gaps between cost, outcomes, and real-world workflows are where the statistics start to feel uncomfortable and worth a closer look.
