Abstract

OBJECTIVE
Current guidelines for initiating dialysis therapy are based on level of kidney function and clinical evidence of uremia. In several studies, early dialysis showed no benefit in mortality and complication rate. Thus we examined whether the timing of initiation of dialysis influenced mortality and complication rate with renal failure.
METHODS
We retrospectively studied the clinical outcomes in 290 patients with renal failure who underwent dialysis therapy from 2001 to 2009. The early and late dialysis group defined as values more than and less than 10 mL/min/1.73 m2. The primary outcome was death from any cause and the secondary outcome was complication event.
RESULTS
The survival rates and complication events were compared based on the estimated glomerular filtration rate, the survival rate in late dialysis group is better than in early dialysis group and the significant prognostic factors determined by multivariate analysis were age and residual renal function at time of initiation of dialysis. No difference in complication events were observed. Subgroup analysis in hemodialysis group shows no significant difference in survival rate.
CONCLUSION
The survival rate in late dialysis group is better than in early dialysis group. And the complication rate were not different in two groups.
