Ultrafiltration Profiling and Outcomes Among Individuals on Maintenance Hemodialysis
In Brief
A clinical study evaluating UF profiling during HD and Conventional HD for End Stage Renal Disease. Completed, enrolled 34 participants across 2 sites.
Detailed 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.
Study Details
Timeline
Interventions
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.
Control arm: Conventional HD (routine care) is the participant's standard HD prescription without UF profiling.
