Objective:

To evaluate the impact of a diagnostic stewardship program on respiratory culture use in pediatric intensive care units (PICUs).

Approach:
  • Study Design: A multicenter cohort study conducted across 15 US PICUs from 2019 to 2023.
  • Intervention: Implementation of clinical decision support tools, including checklists and algorithms, to standardize endotracheal aspirate culture collection.
Key Findings:
  • Respiratory culture use decreased by 16% from 7.80 to 6.55 cultures per 100 ventilator-days.
  • Cultures repeated within 3 days declined from approximately 13% to 10%.
  • No increase in adverse outcomes such as length of stay, readmissions, sepsis, or antibiotic use was observed.
Limitations:
  • Variable reductions in culture rates between centers indicate local practice influences effectiveness.
  • Patient-level data were unavailable, and rare safety events may have been missed.
Conclusion:

Further research is needed to integrate stewardship into routine workflows and assess its sustainability and cost impact.
