ARTICLE HIGHLIGHTS
Research background
Early identification and subsequent clinical intervention of acute kidney injury (AKI) in traumatic brain injury (TBI) patients are critical to survival.
Research motivation
The exact definition of AKI for patients with TBI is unknown.
Research objectives
We aimed to compare four AKI diagnostic criteria to determine AKI incidence/stage and their association with the in-hospital mortality rate of patients with TBI.
Research methods
The subjects in this study were assessed for the presence and stage of AKI using four different AKI diagnostic criteria.
Research results
The in-hospital mortality rates increased with the AKI stage in all four definitions. The severity of AKI by all definitions and stages was not associated with in-hospital mortality in the multivariable analyses (all P > 0.05).
Research conclusions
This study revealed that Kidney Disease Improving Global Outcomes (KDIGO) is the best method to define AKI in patients with TBI.
Research perspectives
In the future, it is necessary to increase the sample size for prospective studies to further explore.
