Steve, it is my understanding that your neph is the one who sends in the prescribed amount for your wife's needs. Who does the ordering for her? If they are just sending this stuff because they can, you need to tell neph and have he/she call and tell them to back off. They don't care wether she uses them or not, cause they get paid by your insurance.
I would have the order decreased till you get some of your inventory down, or else you are going to be overloaded. My neph works real well with us on this and we have just enough supplies with a little for Emergency.
Does your wife have a fistula? Some of the things you are recieving seem more like use on a graft or cath, so as to prevent infections (ie Iodine & the Lotion Soap). Who sends the supplies? If you are on NxStage, they send supplies too, that deal directly with dialysis, but Frescenius sends the other stuff, gloves, mask ect......
