A Pragmatic Clinical Trial Comparing the Risk of Acute Kidney Injury During Treatment With Vancomycin and Piperacillin-Tazobactam vs. Vancomycin and Cefepime in Hospitalized Patients

Vancomycin is a glycopeptide antibiotic used to treat infections caused by Gram-positive bacteria, including those due to methicillin-resistant Staphylococcus aureus. Dosing of vancomycin will follow standard of care procedures, including the use of individualized dosing regimens developed in consultation with clinical pharmacists, based on participant body weight and renal function, and dosage titration guided by therapeutic drug monitoring. Vancomycin is administered via intermittent intravenous infusions of 60-90 minutes.

Piperacillin-tazobactam is an anti-pseudomonal penicillin with a dose range of 2.25 g or 4.5 g and frequency of every 6 or 8 hours based on a participant's body weight, renal function, and clinician discretion. Piperacillin-tazobactam is administered via extended-duration (4 hours) intravenous infusions

Cefepime is an anti-pseudomonal cephalosporin with a dose range of 500 mg, 1,000 mg, or 2,000 mg, and frequency every 8, 12, or 24 hours based on a participant's body weight, renal function, and clinician discretion. Cefepime is administered via extended-duration (4 hours) intravenous infusions
