Acute kidney injury risk-based screening in pediatric inpatients: a pragmatic randomized trial.

Abstract

BackgroundPediatric acute kidney injury (AKI) is common and associated with increased morbidity, mortality, and length of stay. We performed a pragmatic randomized trial testing the hypothesis that AKI risk alerts increase AKI screening.MethodsAll intensive care and ward admissions of children aged 28 days through 21 years without chronic kidney disease from 12/6/2016 to 11/1/2017 were included. The intervention alert displayed if calculated AKI risk >50% and no serum creatinine (SCr) was ordered within 24 hours. The primary outcome was SCr testing within 48 hours of AKI risk >50%.ResultsAmong intensive care admissions, 973/1,909 (51%) were randomized to the intervention. Among those at risk, more SCr tests were ordered for the intervention group than for controls (418/606, 69% vs. 361/597, 60%, p=0.002). AKI incidence and severity were the same in intervention and control groups. Among ward admissions, 5,492/10,997 (50%) were randomized to the intervention, and there were no differences between groups in SCr testing, AKI incidence, or severity of AKI.ConclusionsAlerts based on real-time prediction of AKI risk increased screening rates in intensive care but not pediatric ward settings. Pragmatic clinical trials provide the opportunity to assess clinical decision support and potentially eliminate ineffective alerts.
