Insights

A pharmacist-led Antimicrobial Stewardship Program (ASP) using care bundles improved outcomes for pediatric Staphylococcus aureus bacteremia. This approach reduced mortality and reinfection rates, identifying key factors for better patient management.

Area of Science:

  • Infectious Diseases
  • Clinical Pharmacy
  • Public Health

Background:

  • Care bundles are established strategies for enhancing treatment efficacy.
  • Pharmacist-led Antimicrobial Stewardship Programs (ASP) can effectively guide clinical decisions and improve patient outcomes.
  • This study focuses on a pharmacist-led ASP utilizing a care bundle for Staphylococcus aureus bacteremia (SAB) in a pediatric setting.

Purpose of the Study:

  • To evaluate the impact of a pharmacist-led ASP with a care bundle on clinical outcomes in pediatric patients with Staphylococcus aureus bacteremia.
  • To assess the effect on infection-related mortality and 90-day reinfection rates.
  • To identify risk factors influencing outcomes in pediatric SAB.

Main Methods:

  • Retrospective cohort study in a Brazilian pediatric hospital (2014-2021).
  • Included 120 pediatric patients with S. aureus bacteremia.
  • Compared pre-intervention (n=44) and intervention (n=76) periods, with the intervention featuring a pharmacist-led ASP and care bundle (2017-2021).

Main Results:

  • Multivariate analysis identified significant factors impacting outcomes: infant patients (OR 12.998), use of >3 antimicrobial regimens (OR 0.006), intervention period (OR 0.060), follow-up blood culture (OR 18.953), early source control (OR 0.002), and de-escalation to oxacillin (OR 0.041).
  • The pharmacist-led ASP model demonstrated increased adherence to the care bundle.
  • A reduced probability of negative outcomes was observed during the intervention period.

Conclusions:

  • The pharmacist-led ASP model, incorporating a care bundle, improved adherence and reduced negative outcomes in pediatric S. aureus bacteremia.
  • Key risk factors were identified, providing insights for enhanced clinical management.
  • This strategy contributes to better patient outcomes in the pediatric population.
