Estudio epidemiológico de 7316 pacientes en hemodiálisis tratados en las clínicas Fresenius Medical Care de Espa？a, con los datos obtenidos mediante la base de datos EuCliD？: resultados de los a？os 2009-2010

observational study of patients on haemodialysis (hd) in fmc？ spain clinics over the years 2009 and 2010. data was collected from the euclid？ database, implemented in the fmc？ clinics, which complies with the following features: online record, mandatory, conducted in incident patients and covering the entire population on hd in these clinics. it aims to understand the characteristics of patients and treatment patterns, comparing them with other studies described in the literature and in order to improve their prognosis and quality of life. it includes 2637 incident and 4679 prevalent patients, which makes a total of 7316 patients. in prevalent patients: 24.4% were diabetic; 76.3% had cardiovascular disease (cvd) and 13.4% cancer. among the incident patients these percentages were: 33.5% diabetic; 80.6% had cvd and 12.6% cancer. the prevalent patients had vascular access such as: avf 68.5%, prosthesis 5.6%, permanent catheter 23.7% and 2.3% temporary catheter. the average duration of the sessions of hd was 230 minutes. 23.2% of prevalent patients were on on-line haemodiafiltration. these patients' hospitalisation rates were 0.46 hospitalisations per incident patient per year and 0.52 per prevalent patient per year. the annual gross mortality rate was 12%. the mortality of hd patients in this study is smaller than those of the spanish registry of dialysis and transplant (grer). the result of morbidity and mortality of the fmc clinics of spain can, therefore, be considered good when compared with those of the grer and other international series. this does not mean that there are no areas of improvement as the increase in the dialysis time, the percentage of patients on on-line haemodiafiltration, convective techniques and the percentage of fav.
