I use an FMC center, and do home hemo (tried BabyK for a few months; am now on NxStage). I have never had any problem booking some in-center appointments when my wife travels and is unavailable to cover for emergencies (I do the treatments without help). I also don't hesitate to ask for an in-center appointment or two if I have the slightest problem with treatment and want to make sure I am "on track". They didn't give me a specific limit on the number of days I can do this, and they even held me hostage in the clinic for a month (due to valid medical reasons - I was recovering from surgery).
The clinic has a NxStage they use for training. If the home training RN is working at the clinic that day, and the machine is not being used for training, I get to use that machine. If not, it's into one of the main clinic chairs.
I always self-canulate - at home; in center or hospital. I take blunts with me when traveling (and not the kind of blunt used to relieve nausea
), and I once visited a small clinic that did not stock them and had never seen a buttonhole fistula.
