Red Blood Cell Distribution Width as a Pragmatic Marker for Outcome in Pediatric Critical Illness.

ABSTRACT:

Background

Red cell distribution width (RDW) is a routine laboratory measure associated with poor outcomes in adult critical illness.

Objective

We determined the utility of RDW as an early pragmatic biomarker for outcome in pediatric critical illness.

Methods

We used multivariable logistic regression to test the association of RDW on the first day of pediatric intensive care unit (PICU) admission with prolonged PICU length of stay (LOS) >48 hours and mortality. The area under the receiver operating characteristic curve (AUROC) for RDW was compared to the Pediatric Index of Mortality (PIM)-2 score.

Results

Over a 13-month period, 596 unique patients had RDW measured on the first day of PICU admission. Sepsis was an effect modifier for LOS >48 hours but not morta
