I go to a university health system. They always ask how you would like to receive your information - in writing, have someone talk to you, in a different language, with someone with you, etc.
If there is a problem with doctors not speaking in plain English, it’s my contention that it’s the patient’s fault for not demanding an explanation they can understand. I know a number of elderly people who will not confront the doctor at all, but wait until they get home and ask their grown children to explain things.
My grandmother always has one of my aunts or uncles go with her to the doctor.
