Are diabetics good candidates for daily home hemodialysis?

No: Well, i assume you are talking about diabetics with impaired renal function, but just to make sure we're on the same page, a diabetic must have significantly decreased renal function to be considered for dialysis. Not all patients will qualify for that. I'd get a referral to a kidney specialist to start the process of determining what modality will be best for the person in question.

??: Not unless they have end stage kidney failure, if i understood the question.
