UK Renal Registry 16th annual report: chapter 10 haemoglobin, ferritin and erythropoietin amongst UK adult dialysis patients in 2012: national and centre-specific analyses.

INTRODUCTION Anaemia treatment in chronic kidney disease (CKD) patients has changed dramatically since the implementation of erythropoietin stimulating agents (ESAs) and has shifted the emphasis from treating severe anaemia in dialysis patients to preventing anaemia. The aim of this chapter is to determine the extent to which the UK Renal Association (RA) and National Institute for Health and Care Excellence (NICE) guidelines for anaemia management are met in the UK. METHODS Quarterly data were obtained for haemoglobin (Hb) and factors that influence Hb from UK renal centres for the incident and prevalent renal replacement therapy (RRT) cohorts for 2012. RESULTS In the UK, in 2012, 51% of patients commenced dialysis therapy with Hb 100 g/L (median Hb 100 g/L). Of patients in the early presentation group, 54% started dialysis with Hb 100 g/L whilst 34% of patients presenting late started dialysis with Hb 100 g/L. The UK median Hb of haemodialysis (HD) patients was 112 g/L, with 82% of patients having Hb 100 g/L. The median Hb of peritoneal dialysis (PD) patients in the UK was 114 g/L, with 85% of patients having Hb 100 g/L. The median ferritin in HD patients in the UK was 431 µg/L and 95% of HD patients had a ferritin 100 µg/L. In EW&NI the median ferritin in PD patients was 285 µg/L (IQR 164-466) with 88% of PD patients having a ferritin 100 µg/L. In EW&NI the median ESA dose was higher for HD than PD patients (7,248 vs. 4,250 IU/week). The percentage of patients treated with an ESA and having Hb >120 g/L ranged between centres from 7-39% for HD and from 0-33% for PD. CONCLUSIONS There was poor correlation between median Hb achieved and median ferritin and ESA usage across the EW&NI centres. There was also a significant variation between centres in the percentages of patients treated with an ESA and having Hb >120 g/L. © 2014 S. Karger AG, Basel.
