Clinical Study of Individualized Vancomycin Dosing Based on Population PK Model

The experimental group will be guided at the bedside with individualized vancomycin dosing by a drug dosimetry software tool that incorporates a PK model developed by Roberts JA et al. for data from sepsis patients. The model developed by Roberts JA et al. has been validated in multiple centers to have a good ability to predict the concentration-time data of patients. Once the basic information of participants such as gender, age, body weight, and creatinine clearance rate (CCR) is entered, the software tool can calculate the dosing regimen that is estimated to achieve the pharmacodynamic (PD) target. The area under the curve (AUC24) of 400-600mg·h/L is identified as the PD target of vancomycin.

The control group will be administered empirically (15-20 mg/kg vancomycin infused intermittently every 8-12 hours depending on the actual body weight of participants).
