I am no long allowed outside because of risk of infection, although its lung infection not PICC infection.
And I agree with you on the insurance view, however, that's insurance's policy, not mine. In their eyes, it's not subjective. If he can leave, he doesn't have to be at the hospital. I used to be able to go out to eat with my family, even when I was pretty sick, but insurance stopped those quick by saying if I left hospital grounds for any length of time (because I had to get a day pass, it was recorded), they would not pay for the hospital stay.
