Something I didn't consider in my previous post was the incompetence and lack of knowledge / laziness of other health professionals.
We picked up a bloke the other day who had been seen by his GP for an ongoing chest infection. The prescribed drugs weren't kicking in, so a couple of days and a few more visits later our patient is sent home again with no new treatment.
The patient calls the surgery again, stating the not improving condition, and wants to make another appointment.
The reply from the other end of the phone line? Call an ambulance, and go to hospital.
After all, we still are DFAs.
