PURPOSE: The objective of this study was to compare the incidence of acute kidney injury (AKI) among critically ill patients receiving combination therapy with vancomycin plus piperacillin-tazobactam (VPT) against patients receiving vancomycin plus cefepime (VC). METHODS: A retrospective cohort study of adult patients admitted to an intensive care unit between September 2012 and December 2016 was conducted. Patients were included if they received combination therapy with VPT or VC for ≥48 hours. Patients were excluded if creatinine clearance was <60 mL/min or received renal replacement therapy prior to the initiation of therapy. The primary end point was AKI, as defined by the Acute Kidney Injury Network classification, during or within 48 hours of completion of therapy. The incidence of AKI was compared between groups and multivariate analysis was performed to control for relevant confounders. RESULTS: = 0.114). Multivariate analysis revealed vancomycin trough >20 mg/L (odds ratio, OR [95% confidence interval, CI] = 2.69 [1.62-4.47]), baseline SCr (OR [95% CI] = 3.34 [1.43-7.80]), vasopressors (OR [95% CI] = 1.77 [1.04-3.04]), and duration of combination therapy (OR [95% CI] = 1.009 [1.003-1.015]) as independent risk factors for AKI. CONCLUSION: The risk of AKI was similar between VPT and VC groups in critically ill patients. Risk factors for AKI were related to baseline renal function, duration of combination therapy, supratherapeutic vancomycin troughs, and severity of ill...
