I have a friend with the same problem. She now volunteers for a charity which organises transport to hospital appointments etc. Apparently you can block off the days you’re busy on the website and also choose days and times when you’re available. I’m afraid I don’t have any more details. My friend lives quite far from me but I think this service is quite widespread.

Goodness, look what I just found…
