Summary

The rate of fluid removal (ultrafiltration, UF) during hemodialysis (HD) may contribute to cardiovascular morbidity and mortality among individuals receiving maintenance HD. More rapid UF rates are associated with higher morbidity and mortality. Ultrafiltration profiling, the practice of varying UF rates to maximize fluid removal during periods of greatest hydration and plasma oncotic pressures, is one treatment modification that may reduce UF-related harm without necessitating reduction in interdialytic fluid intake or longer HD treatments. To date, UF profiling has not been adequately studied independent of sodium profiling.

This study investigates the comparative effect of UF profiling versus non-profiled conventional HD on select cardiovascular and patient-reported outcomes. Participants will complete two phases of UF profiling and two phases of conventional HD and will act as their own controls.

Conditions

Interventions

OTHER

UF profiling during HD

Experimental arm: Linear UF profiling (linearly decreasing UF rate with a UF rate starting at 1.33 times the rate that would be needed at a constant UF rate to achieve the desired post-weight; pre-programmed "profile 2" on a Fresenius 2008K machine, the machine used in all participating clinics). Ultrafiltration profiling will be performed using Fresenius 2008K dialysis machines in accordance with manufacturer instructions.

OTHER

Conventional HD

Control arm: Conventional HD (routine care) is the participant's standard HD prescription without UF profiling.
