Thanks Sheryl and others. I am pleased to say that you were correct, and a deal was struck between the hospital, ourselves and the insurers WR life, who have been great all through this.
The hospital offered day infusion with a pill, almost the same price, but potentially more debilitating according to them. They still insisted that the infusion took 2 days, it was an American programme. As one of the correspondents said, she preferred to be in hospital rather than at home. So a deal was struck with the insurer, for which I am not privie to the details. So. all good, and thanks again for all your comments.
