5 Key Takeaways

• 1

  Clinical decision support reduced respiratory culture use by 16% across 15 US pediatric intensive care units without adverse patient outcomes.

• 2

  Endotracheal aspirate cultures often indicate colonization rather than infection, contributing to overdiagnosis and unnecessary antibiotic treatment.

• 3

  The study evaluated a diagnostic stewardship program implemented from 2019 to 2023, focusing on standardizing culture collection practices.

• 4

  The adjusted mean monthly culture rate fell from 7.80 to 6.55 cultures per 100 ventilator-days after the program's implementation.

• 5

  Reducing testing did not increase bronchoalveolar lavage cultures, length of stay, readmissions, or antibiotic use, indicating safety in the approach.
