Early Sequential Risk Stratification Assessment to Optimize Fluid Dosing, CRRT Initiation and Discontinuation in...

Area of Science:

• Pediatric Critical Care Medicine
• Nephrology
• Biomarker Discovery

Background:

• Acute Kidney Injury (AKI) is prevalent in critically ill children, leading to significant morbidity and mortality.
• Delayed recognition of AKI often results in clinically significant Fluid Overload (FO), worsening patient outcomes.
• Early identification and intervention strategies are crucial for mitigating AKI- and FO-related complications.

Purpose of the Study:

• To evaluate a novel AKI Clinical Decision Algorithm (CDA) for sequential risk stratification in critically ill children.
• To assess the predictive accuracy of the CDA for severe AKI, Fluid Overload (FO) >10%, and Continuous Renal Replacement Therapy (CRRT) requirement.
• To standardize the Furosemide Stress Test (FST) for pediatric use within the CDA.

Main Methods:

• A single-center prospective observational cohort study in a Pediatric Intensive Care Unit (PICU).
• Integration of the Renal Angina Index (RAI), urine Neutrophil Gelatinase-Associated Lipocalin (NGAL), and Furosemide Stress Test (FST) for risk stratification.
• Evaluation of 2100 patients over three years to identify severe AKI, FO >10%, and CRRT requirements.

Main Results:

• The study aims to standardize a pediatric FST and assess the CDA's predictive accuracy for severe AKI, FO >10%, and CRRT.
• Secondary analyses will examine renal function recovery, RRT use, and mortality within 28 days in patients with AKI.

Conclusions:

• This research represents the first prospective evaluation of a cohesive AKI CDA integrating multiple predictive tools.
• The study will provide crucial insights into the feasibility and predictive capabilities of the CDA for FO and AKI in critically ill children.
• Findings will offer actionable data for early, risk-stratified interventions in pediatric critical care.
