Individualizing the dialysis tx

In the years that I have been on dialysis, I have not encountered one nephrologist, RN or tech who knows how to individualize the tx via the machine parameters. It is as if their ed/training only goes so far. Machines have the capability to do so much more to make the tx. balanced and comfortable, yet if dialysis staff are not trained, accordingly, the machine’s capacity for same is wasted.

I am glad that patients are getting good txs with short daily and nocturnal txs. But I am wondering if anyone has had the benefit of dialysis staff that do know how to individualize txs with regular 3x a week txs?
