What is the target vancomycin AUC24/MIC for MRSA bacteremia?

The 2020 ASHP/IDSA/SIDP guidelines recommend AUC24/MIC target of 400–600 mg·h/L (assuming MIC 1 mg/L) to optimize MRSA bacteremia outcomes while minimizing nephrotoxicity from excessive exposures.

How does AUC monitoring differ from trough monitoring for vancomycin?

AUC monitoring uses two vancomycin levels (one mid-infusion, one 1-2h post-infusion) to estimate individual PK parameters and achieve target AUC, while trough monitoring alone is no longer recommended due to poor correlation with outcomes.
