Dialysate bicarbonate practices

1.What is your dialysis program (province, city, name of dialysis program/affiliated hospital and/or university)?
2.What hemodialysis machine does your program use (i.e., make/model)
3.Is bicarbonate delivery performed at the level of the individual hemodialysis machine (vs. centralized delivery system)?
4.What bicarbonate product does your program use?
5.Does your program adjust the dialysate bicarbonate concentration regularly (i.e., weekly or monthly) based on individual patient factors, such as pre-dialysis serum bicarbonate concentration?
6.For chronic dialysis patients, does your program use a different dialysate bicarbonate concentration in the inpatient/acute setting compared to the outpatient setting?
7.Does your program prescribe the same dialysate bicarbonate concentration for >90% of patients?
8.What is the dialysate bicarbonate concentration prescribed for most patients in your program?
9.For the purposes of a trial examining the impact of different dialysate bicarbonate concentrations on patient outcomes, what is the lowest concentration you would be willing to randomize patients to?
10.For the purposes of a trial examining the impact of different dialysate bicarbonate concentrations on patient outcomes, what is the highest concentration you would be willing to randomize patients to?
11.Does your program prescribe oral sodium bicarbonate to chronic hemodialysis patients?
12.Would your dialysis program be willing to participate in a national, cluster randomized pragmatic trial that compares two different standard dialysate bicarbonate concentrations to one another?
