Fluid removal is a key component of dialysis treatment but, if excessive, can result in a faster decline in residual kidney function. Prescribing the optimal removal of fluid on dialysis to avoid this is therefore important. Bioimpedance spectroscopy, a bedside device that estimates tissue hydration, might improve this prescription, so reducing the rate of decline in kidney function and improving patient outcomes. We wished to establish the efficacy and cost-effectiveness of bioimpedance in pursuing this treatment strategy.
