My grandfather had non-functioning kidneys during the last few years of his life. So he had to go to the hospital two or three times a week for ambulatory care, that is dialysis. It was difficult for him but since this was an ongoing treatment, it wasn't possible for him to stay at a hospital all the time. And he wouldn't have wanted that either. So he would go to the hospital, have the dialysis which took almost all day and then return home by evening.
