I don't know what the answer is but a simpler system might help. For instance, my Dh was sent a routine hospital appointment at very short notice. If we'd happened to be away on holiday, he'd have been completely unaware of the appt but would have been down as a No Show, which would be unfair.
Some people seem to have no problem getting appointments, though. I know someone who must see the doctor just about every week. She made an appointment for the week before Christmas just in case she felt ill and needed to see the doctor! I've decided that if there's a three-week wait if I need to see a doctor, I'll get this friend to make the appointment for me. 
He never gives up being stupid.
