My husband is on home hemodialysis, and has been since 2008. He lost one kidney to adrenal cancer and the other had been failing, but we didn't know it.
A few things:
There are two types of dialysis. Hemo and peritoneal. Either one can be done in center (clinic) or at home. You can also do nocturnal hemo (which is dialysis extended over 8 or so hours) Both have their high points and low points. However, doing dialysis at home is the better option, IMHO.
In center, the techs are dealing with multiple patients (depending on the regulations where you live, it can be as many as 15). The tech does not have time to oversee everyone as closely as they should, especially with the elderly patients.
My DH says that being in center is rougher on the body than doing home. in center, it was 3 days a week, for about 3-1/2 to 4 hours a day. When you think about the fact that your kidneys work 7 days a week, 24 hours a day, that is pretty substandard. So, your "gunk" doesn't get cleaned out, you get tired and cranky and you don't have any energy.
On home hemo (I can't speak for Peri, we have not done that), we run 6 days a week for about 3-1/2 hours a day. DH decides how much fluid he needs to take off (instead of a tech, who doesn't understand that taking off more than 1.0 makes DH physically sick, but will insist on doing it anyways because he is 2.0 over his weight); he decides what day or days to take off; and we control what happens during the treatment.
Now, doing home hemo does require a partner, at least in training. My dh can run his entire tx himself, now that his fistula in his left arm is matured. Before, when he had a catheter, there was no way he could do it himself. So someone, or multiple someones, have to be available for that time frame as well.
One other thing to remember, with the catheter, you cannot get it wet. DH's was in his upper chest, so no showers. That was a long 8 months, with only sponge baths. He was so irritable and angry at the world, on top of feeling sick and weak all the time. But now, he is much much better.

He made it through the last week with very little "required" physical downtime..which is really awesome since in 2008, he couldn't even walk around the Jax Zoo without passing out after 30 minutes.
All in all, it takes a lot of commitment to do dialysis, on both the patient and the caregiver's sides. There is a lot of information out there, I can post some links if you would like. But please, take into account what she wants. My DH said that if he had to continue in center, he would have stopped tx, and allowed nature to take its course.
