Utilization of the renal angina index in PICU of a developing country for prediction of subsequent severe acute kidney injury.

Background: Acute kidney injury (AKI) is independently associated with worsened morbidity and increased mortality in the pediatric intensive care unit (PICU). AKI risk score, termed renal angina index (RAI) is used in developed countries to predict subsequent severe AKI. Very few studies have investigated application of RAI in the PICU of a developing country.
