    RESULTSThe intervention group showed an improved median percentage of hemoglobin measurements within target at 47% (IQR 39 to 58), with a 10 percentage points median difference between the two groups (95% CI: 3 to 16; P=0.008). The odds ratio of being within the hemoglobin target in the standard of care group compared to the group receiving the personalized ESA recommendations was 0.68 (95% CI: 0.51 to 0.92). The variability of hemoglobin levels decreased in the intervention group, with the percentage of patients experiencing fluctuating hemoglobin levels being 45% vs 82% in the standard of care group. ESA usage was reduced by about 25% in the intervention group.CONCLUSIONSOur results demonstrated an improved hemoglobin target attainment and variability by employing personalized ESA recommendations using the physiology-based anemia therapy assistance software.BACKGROUNDAnemia is common among hemodialysis patients. Maintaining stable hemoglobin levels within predefined target levels can be challenging, particularly in patients with frequent hemoglobin fluctuations both above and below the desired targets. We conducted a multi-center, randomized, controlled trial comparing our anemia therapy assistance software against a standard population-based anemia treatment protocol. We hypothesized that personalized dosing of erythropoiesis stimulating agents (ESA) improves hemoglobin target attainment.METHODSNinety-six patients undergoing hemodialysis and receiving methoxy polyethylene glycol-epoetin beta were randomized 1:1 to the intervention group (personalized ESA dose recommendations computed by the software) or the standard of care group for twenty-six weeks. The therapy assistance software combined a physiology-based mathematical model and a model predictive controller designed to stabilize hemoglobin levels within a tight target range (10 to 11 g/dl). The primary outcome measure was the percentage of hemoglobin measurements within the target. Secondary outcome measures included measures of hemoglobin variability and ESA utilization.
