Hi. I don't know how common it is for healthcare professionals to be able to communicate with BSL, but I can tell you that I'm learning BSL myself specifically because I'm currently on the path to becoming a paramedic. I know it'll come in handy at times, and in times when people are in distress where using an alternative form of communication might be far more difficult or impossible, and so that's my main reason for learning. I don't know how common it is, or how encouraged it is in the healthcare system itself, all I know is I can't be the first.
