Early start of dialysis has no survival benefit in end-stage renal disease patients.J Korean Med Sci. 2012 Oct; 27(10):1177-81.JK
The timing for dialysis initiationis still debated. The aim of this study was to compare mortality rates, using a propensity-score approach, in dialysis patients with early or late starts. From January 2000 to June 2009, incident adult patients (n = 836) starting dialysis for end-stage renal disease (ESRD) were enrolled. The patients were assigned to either an early- or late-start group depending on the initiation time of the dialysis. After propensity-score-basedmatching, 450 patients remained. At the initiation of dialysis, the mean estimated glomerular filtration rate (eGFR) was 11.1 mL/min/1.73 m(2) in the early-start group compared with 6.1 mL/min/1.73 m(2) in the late-start group. There were no significant differences in survival between the patients in the early- and late-start groups (Log rank tests P = 0.172). A higher overall mortality risk was observed in the early-start group than in the late-start group for the patients aged ≥ 70 yr (hazard ratio [HR]: 3.29; P = 0.048) and/or who had albumin levels ≥ 3.5 g/dL (HR: 2.53; P = 0.046). The survival of the ESRD patients was comparable between the patients in the early and late-start groups. The time to initiate dialysis should be determined based on clinical findings as well as the eGFR.
