Observational Study of Pediatric Acute Kidney Injury, Risk Factors and Outcomes

Pediatric acute kidney injury (AKI) is associated with increased morbidity and mortality in critically ill patients. Currently, understanding of the epidemiology and diagnosis of AKI in children is limited by single center retrospective data and inconsistent diagnostic and stratification criteria. The hypotheses of the AWARE study is that 1) renal angina, a composite of early injury signs and risk of disease, will predict severe subsequent AKI in critically ill children and 2) the incorporation of urinary biomarkers into the renal angina scoring system will improve the prediction of the severe injury. The AWARE study is conducted to describe AKI epidemiology in a heterogeneous multinational cohort of critically ill children, characterize AKI risk factors and associated morbidity, and validate the KDIGO AKI criteria as a predictor of pediatric AKI outcomes. The multi-center, multi-national registry will create the largest ever repository of information available on AKI in children.
