Frailty syndrome and end-stage kidney disease outcomes at a Latin American dialysis center

Abstract

Introduction. Frailty syndrome generates a high risk of adverse outcomes and mortality, and its prevalence is elevated in patients with end-stage kidney disease. Few studies have reported the prevalence and outcomes of frailty in populations from less developed countries. Objective. To identify the clinical outcomes and factors associated with the frailty syndrome in patients with stage five chronic kidney disease who started renal replacement therapy – both hemodialysis and peritoneal dialysis– in a dialysis center in Bucaramanga, Colombia. Materials and methods. This was a prospective study of patients with end-stage kidney disease who initiated dialysis at a center in Colombia and had a twelve-month follow-up. Results. The overall frailty prevalence was 50.47% and two out of three patients older than 65 years had the syndrome. We found significantly higher followup mortality among patients with frailty: odds ratio of 2.95 (CI: 1.07- 8.13; p=0.036) in unadjusted analysis. Conclusions. Literature shows that compared to developed nations, Latin American adults are facing a higher prevalence of chronic diseases, and frailty syndrome is raising. In this study, according to the FRAIL scale, having a frailty syndrome predicts a higher mortality; hypoalbuminemia and low creatinine levels at the beginning of dialysis could act as predictors of its diagnosis.
