Background. A full correction of anaemia in haemodialysis (HD) patients may lead to an increased risk of vascular access (VA) failure. We studied the relationship between haemoglobin (Hb) level and VA survival. Methods. Incident patients between January 2000 and December 2002 with <1 month on HD were considered. The relative risk (RR) of access failure was evaluated in four different groups of patients divided according to their Hb level (<10, 10-12, 12-13 and >13 g/dl). Other factors possibly influencing VA survival were also considered: age, gender, diabetes, vascular disease, intact parathyroid hormone (iPTH) and treatment with an angiotensin-converting enzyme (ACE) inhibitor, angiotensin receptor blocker (ARB) or recombinant human erythropoeitin therapy. Results. We studied 1254 patients (1057 with autologous fistulae, 75 grafts and 122 permanent catheters at admission). Based on Cox analysis, we found the next statistically significant RR of VA failure to be 2.3 times higher with grafts than with arterio-venous fistulae (AVFs) and 1.8 times higher in AVFs with Hb <10 g/dl than in AVFs of the next Hb group. There was no statistically significant difference in the RR of VA failure between patients with Hb 10-12 g/dl and those with Hb 12-13 g/dl or >13 g/dl. Diabetes (RR: 1.41, P ¼ 0.06), age >65 years (RR: 1.32; P ¼ 0.11) and iPTH (RR: 1.56; P ¼ 0.01) were identified as predictive factors for VA failure; ACE inhibitors or ARB (RR: 0.69; P ¼ 0.03) were found to be protective factors. Conclusions. In the studied population, the correction of Hb level to >12 g/dl was not associated with a higher incidence of VA thrombosis than in patients with Hb between 10 and 12 g/dl. ACE inhibitors or ARBs were found to be protective factors, and diabetes, age >65 years and iPTH >400 pg/ml were negative predictive factors for VA survival.
Background: Data from the Dialysis Outcomes and Practice Patterns Study (DOPPS) study suggest that the level of implementation of the European Best Practice Guidelines (EBPG) is at best partial. The main aim of this study is to describe the level of implementation of the EBPG in the European Fresenius Medical Care (FME) clinic network. Methods: Data presented in this investigation were gained through the FME database EuCliD® (European Clinical Database). Patient data from 4 countries (Great Britain, France, Italy, Spain) were selected from the EuCliD® database. The parameters chosen were haemodialysis adequacy, biocompatibility, anaemia control and serum phosphate control, which are surrogate indicators for quality of care. They were compared, by country, between the first quarter (Q1) 2002 and the fourth quarter (Q4) 2005. Results: During Q1 2002 and Q4 2005, respectively, a total of 7,067 and 9,232 patients were treated in FME clinics located in France, Italy, Spain and the UK. This study confirms variations in haemodialysis practices between countries as already described by the DOPPS study. A large proportion of patients in each country achieved the targets recommended by the EBPG in Q4 2005 and this represented a significant improvement over the results achieved in Q1 2002. Conclusions: Differences in practices between countries still exist. The FME CQI programme allows some of these differences to be overcome leading to an improvement in the quality of the treatment delivered.
