Effect of therapeutic drug monitoring-based dose optimisation of piperacillin/tazobactam in sepsis patients

Growing evidence suggests that insufficient antibiotic exposure (defined as failure to achieve the pharmacokinetic/pharmacodynamic (PK/PD) target to kill or inhibit the growth of a pathogen) is associated with worse clinical outcomes in sepsis patients.

Moreover, up to 50% of critically ill patients receiving a β-lactam antibiotic with regimens based on manufacturers' recommendations fail to reach the target.

Therapeutic drug monitoring (TDM)-guided therapy has been proposed as a strategy to further optimise the achievement of the PK/PD target of β-lactam antibiotics. However, there are no data on whether piperacillin/tazobactam TDM can improve clinical outcomes.

In this context, a large RCT was performed to investigate whether TDM-based dose optimisation versus fixed dosing could improve clinical outcomes in patients with sepsis treated with piperacillin/tazobactam as a continuous infusion.

Dr Hagel shares with us the results of this study published in the ICM Journal.
