Prediction of Severe Acute Kidney Injury using Renal Angina Index in a Pediatric Intensive Care Unit.

Objective: To determine the proportion of children in a pediatric intensive care unit with a positive Day 0 Renal angina index who develop severe acute kidney injury (AKI) on Day 3; and to compare the predictive ability of the index with that of individual markers of renal injury, for the development of severe acute kidney injury.

Design: Observational study.

Setting: Pediatric intensive care unit of a tertiary-care hospital.
