American scholars have found that in patients with acute kidney injury (AKI) 
with a significant increase in serum creatinine, initial dialysis is associated 
with increased survival. Conversely, for patients with AKI with lower serum 
creatinine, initial dialysis and mortality. Increase correlation. The paper was 
published online April 7 in the Journal of the American Society of Nephrology 
(Clin J Am SocNephrol).
The study included 6119 patients with severe AKI, of which 602 received 
dialysis. The results of the study showed that after matching the propensity 
scores, the covariates between the dialysis and non-dialysis patients were well 
balanced, and the total risk-to-risk ratio (HR) was 1.01 (P=0.89).
For every 1 mg/dl increase in serum creatinine concentration, dialysis 
increased survival benefit by 20% (P = 0.001). After correcting the severity of 
the disease, the results remained unchanged. When the serum creatinine 
concentration is ≥ 3.8 mg / dl, the benefits of dialysis exceed its 
drawbacks.
