To assess the impact of transitioning from trough concentration-guided dosing to area under the concentration-time curve (AUC)-guided dosing on vancomycin-associated nephrotoxicity.
Conducted a single-center, retrospective quasi-experiment evaluating 1,280 hospitalized adult patients receiving intravenous vancomycin between 2014 and 2015.
Utilized multivariable logistic and Cox proportional hazards regression to analyze nephrotoxicity risk while adjusting for severity of illness, comorbidities, therapy duration, and concurrent nephrotoxic agents.
AUC-guided dosing was independently associated with a significant decrease in nephrotoxicity via logistic regression (OR 0.52; 95% CI, 0.34 to 0.80; P = 0.003) and Cox proportional hazards regression (HR 0.53; 95% CI, 0.35 to 0.78; P = 0.002).
Patients in the AUC-guided dosing cohort received lower total daily vancomycin doses and achieved lower overall AUC values and trough concentrations.

Implication

Quasi-experimental study shows reduced nephrotoxicity with AUC-guided vancomycin dosing in hospitalized adults, suggesting precision monitoring minimizes harmful drug exposure.
