Objective: To determine the incidence of vancomycin nephrotoxicity in acutely ill hospitalized children and to secondarily characterize the risk factors for this complication. Methods: A single-center retrospective cohort study conducted at UCSF Benioff Children¡¯s Hospital from June 2012 to June 2015. Inpatients 3 months to <19 years who received intravenous vancomycin for ¡Ý48 hours were included. The primary outcome was incidence of nephrotoxicity, defined as an increase in serum creatinine by ¡Ý50% from baseline. Univariate and multivariate analyses were conducted to identify risk factors for vancomycin nephrotoxicity. Results: A total of 291 patients (272 nonnephrotoxic and 19 nephrotoxic) were included in the analysis. Of the 19 patients, 12 (4.1%) were found to have moderate to severe toxicity. The median duration of therapy was 3 (3-5) and 4 (3-6) days for the group with ¡°no nephrotoxicity¡± and ¡°nephrotoxicity,¡± respectively. The mean time for the serum creatinine to return to normal in patients with nephrotoxicity was 5.1 days. In the multivariate analysis, only final trough concentration ¡Ý15mg/dL (odds ratio = 3.49, 95% confidence interval = 1.2-10.1; P = .021) and receipt of piperacillin/tazobactam (odds ratio = 3.14, 95% confidence interval = 1.02-9.6; P = .046) were significantly associated with nephrotoxicity. Conclusion: The rate of moderate to severe vancomycin-associated nephrotoxicity in acutely ill children is relatively uncommon and reversible.
