Brief Summary

Vancomycin is a glycopeptide antibiotic that is the first line antibiotics for the treatment of serious gram-positive infections involving methicillin-resistant Staphylococcus aureus (MRSA). Its therapeutic window is narrow, so there is a need to monitor serum vancomycin concentration in clinical practice, especially in the critically ill patients. So far, few studies have investigated the clinical outcomes of the dosage strategy that vancomycin dosage is administered and adjusted individually using PPK and Bayesian methods based on observed concentrations. The objective of this study is to investigate the effectiveness, safety and economics of the vancomycin individualized dosing service provided by pharmacists.

Study Arms (2)

Pharmacist consulting group

When physicians make the decision that patients need to prescribe vancomycin or need dose adjustment, they will call for a pharmacist consultation. Pharmacists will provide the initial regimen based on PPK methods if applicable, otherwise give the suggestion of the initial dosage according to guidelines. Also, pharmacists will give suggestions on the time of sampling for serum concentration measurement. For dosage adjustment, pharmacists will be informed the results of serum vancomycin concentration, and then make a calculation using Bayesian estimation to determine whether there is a necessity to change the dosing regimen. Pharmacists will follow the patients until they discharge.
