Our biggest blessing has been the most amazing, caring HHD nurse on the planet - she is just the best. We might not still be hanging in there if not for her.
We went thru both PD training and home hemo training, and I do think the one-on-one direct nursing was one of the best places that my dh got his dialysis needs under control, and then at home we could continue tweaking for his needs. But I sometimes forget how wonderful that training was, going from being one of the masses to getting someone totally devoted to just your patient every day and getting his treatment right.
Also, even after we were home, the monthly meetings for home dialysis were much more focused, compared to the in-center monthly meetings with all the distractions. We brought lots of details to those monthly meetings and came up with lots of solutions.
