Because 93.0% of the patients who initially received EIC remained on EIC, implementation of EIC as the standard dosing strategy was feasible in this pediatric hospital.

The majority of children in this cohort achieved 21-day clinical cure with extended-interval TZP. Those without clinical cure tended to be younger and critically ill. Additional comparative studies evaluating traditional and extended-infusion TZP in children are needed.

In this pediatric study, overall treatment success was observed in 92.5% of patients. Microbiological cure was documented in 91.3% of patients by using follow-up cultures. Length of stay may be positively impacted by CI nafcillin. Continuously infused nafcillin appears to be an acceptable alternative to intermittently infused nafcillin in children. Further studies are needed to address the question of whether clinical outcomes of CI nafcillin are superior to those of conventional infusion.
