Development and Implementation of a Piperacillin-Tazobactam Extended Infusion Guideline

Administration of β-lactam antibiotics by extended infusion optimizes the pharmacodynamic properties and bactericidal activity of these agents resulting in a potential improvement in patient outcomes and reduction in drug expenditure. Consequently, a pharmacist-led piperacillin-tazobactam extended 4-hour infusion guideline was implemented hospital-wide at a 500-bed academic medical center. Each piperacillin-tazobactam infusion was prospectively monitored for 5 weeks to ensure accurate administration and identify barriers to guideline adherence. Overall, a total of 103 patients received 1215 doses of piperacillin-tazobactam by extended infusions. In all, 98% of the doses were administered at the correct extended infusion rate and 94% of the doses were given at the scheduled time.
