There is mounting evidence that combination of antibiotic therapy with vancomycin and piperacillin/tazobactam (pip/tazo) is associated with acute kidney injury (AKI). To determine whether vancomycin plus pip/tazo is associated with higher rates of AKI compared to vancomycin plus cefepime among pediatric hematology/oncology (heme/onc) patients, we examined 121 heme/onc patients receiving at least two consecutive days of therapy with vancomycin and either pip/tazo or cefepime. Rate of AKI was higher in the pip/tazo than the cefepime group (4/27 [14.8%] vs 2/94 [2.1%], P = 0.022).
