SP661SURVIVAL OF HEMODIALYSIS PATIENTS: A NEW REALITY?

Abstract

Introduction: Survival rates of haemodialysis patients have increased worldwide over the last decade. The purposes of this study were to analyze the 10 -year survival rate and to identify mortality risk factors in a Portu- guese cohort. Subjects and Methods: Data was collected from 273 incident patients on facility haemodialysis treatments between 2005 and 2015. Sociodemographic data, medical history, clinical and analytic parameters were collected. A statistical analysis using Kaplan -Meier survival analysis and Cox regression were performed. Results: Median age was 71 ± 15.5 [22; 91] years, 56.8% were male. Fistula was the first access in 68.5%. Median survival rate was 89 ± 8.8 months. There were 93 deaths (34%). Of the 23 deaths occurring in the first year, 65% (n=15) were during the first 90 days. Mortality risk factors were residence in a nursing home (OR 2.8; p<0.05), coronary heart disease (OR 2.3; p<0.05), central venous catheter use (OR 2.1; p<0.05), history of hos- pitalizations in year prior to dialysis admission (OR 1.9; p<0.05) and advanced age (OR 1.5; p<0.05). Conclusions: Patients starting haemodialysis in the last decade are mainly elderly and have a prolonged lifes- pan, reflecting good levels of care. Functional status and dependence, extremes of age, central venous catheter use and high cardiovascular burden are related with greater mortality and should prompt consideration for a more conservative approach.
