Discrepancy in vancomycin AUC/MIC ratio targeted attainment based upon the susceptibility testing in staphylococcus aureus Journal Article uri icon
Overview
abstract
  • This study demonstrated a statistically significant difference in vancomycin minimum inhibitory concentration (MIC) for Staphylococcus aureus between a common automated system (Vitek 2) and the E-test method in patients with S. aureus bloodstream infections. At an area under the serum concentration time curve (AUC) threshold of 400 mgh/L, we would have reached the current Infectious Diseases Society of America (IDSA)/American Society of Health System Pharmacists (ASHP)/Society of Infectious Diseases Pharmacists (SIDP) guideline suggested AUC/MIC target in almost 100% of patients while using the Vitek 2 MIC data; however, we could only generate 40% target attainment while using E-test MIC data (p < 0.0001). An AUC of 450 mgh/L or greater was required to achieve 100% target attainment using either Vitek 2 or E-test MIC results.
