    Study Finds Online Language Barriers Persist in Health Care

    A new University of Michigan study finds that nearly one-third of U.S. hospitals offer patient portals only in English, leaving many non-English speakers with limited access to essential online health services. While language support has improved in person, digital health tools still lag behind in accessibility.
