"Lack of information"

My Dad recently had a catheter fitted. Given that no one is allowed to accompany him due to current restrictions, and that he is hard of hearing and nearly 80 I presumed that he would be sent home with some information/leaflets etc about the procedure he'd had done and the after care required etc. He came home with nothing and struggled to remember the information that he was told at his appointment. He was given one contact telephone number but of course it is obviously office hours only so there was no answer when we rang for help. We have found it really distressing that we have had to use the internet and finally, the 111 service to get help and advice. Not an acceptable way to treat an elderly patient I'm afraid.
