279. A Decision Tree Using Clinical Characteristics to Predict a Hospitalized Child’s Risk of a Multidrug-Resistant Gram-Negative Bloodstream Infection

As the threat of multidrug-resistant Gram-negative (MDRGN) bacteria rises, recognizing children at high risk of bloodstream infections with bacteria resistant to commonly prescribed empiric antibiotics is critical. We developed a decision tree to predict which pediatric bloodstream infections were due to MDRGN bacteria resistant to cefepime or piperacillin–tazobactam, commonly prescribed empiric antibiotics. We conducted a longitudinal...
