The Impact of Lowering Haemoglobin Targets on Patterns of Erythropoiesis-Stimulating Agent Use in Patients on Haemodialysis.

Background/Aims: Haemoglobin (Hb) targets have been reduced in patients receiving haemodialysis (HD). We have investigated the impact of new guidance on current practices and costs. Methods: Anaemia management in all patients undergoing thrice-weekly HD was retrospectively reviewed. Hb targets were compared against Kidney Disease: Improving Global Outcomes 2012 recommendations. The impact of new guidance was assessed by comparing anaemia parameters pre- and post-guideline publication. Results: Two hundred and ninety two patients, with a mean age of 64 years were included. The Hb target range was achieved in 44% patients and was above target in 51%. In a sub-group of 230 patients, the mean Hb did not differ during Q4-2011 and Q4-2012. A reduction in erythropoiesis-stimulating agent (ESA) use was observed. ESA efficiency (Hb/ESA) increased in the later period (6.08 vs. 6.41 g/l/μg) and was associated with a 3% cost reduction. Conclusion: Introduction of guidelines lowering Hb targets in HD patients led to more efficient ESA usage and cost-savings. Anaemia treatment, however, remains unnecessarily aggressive in some patients. Further reductions in Hb and ESA dose are achievable.
