I had umpteen appointments with the pump nurse, trying this, that and the next thing to try and sort out my blood sugars. Eventually she told me to ask to see my consultant at my next clinic appointment, as he had to refer me to the pump consultant. When I was seen months later by the pump consultant, he agreed that I should go on the pump. It was then just a matter of waiting till they had the money for another batch of pumps.
I presume every hospital is different.
