Clinical Report: Diagnostic Stewardship Cuts Testing in Sick Infants
Overview
A diagnostic stewardship program reduced respiratory culture use by 16% in pediatric intensive care units without adverse patient outcomes.
Background
The use of endotracheal aspirate cultures in children with artificial airways is common for diagnosing suspected ventilator-associated infections. However, these cultures often lack specificity, leading to potential overdiagnosis and unnecessary antibiotic treatments. Implementing diagnostic stewardship can help optimize testing practices and improve clinical relevance.

Key Findings
16% reduction in respiratory culture use across 15 PICUs.
No increase in adverse outcomes such as length of stay or readmissions.
Standardized clinical decision support tools were used to guide testing.
Variable effectiveness of the intervention was noted between centers.
Further research is needed to assess integration into routine workflows.
Clinical Implications
Further research is needed to assess integration into routine workflows.
Conclusion
Further research is needed to determine how best to integrate stewardship into routine workflows and assess its sustainability and cost impact.
Large Finnish cohort study identifies coffee-associated patterns in metabolites, risk markers, and sex hormones that could help refine interpretation of cardiometabolic biomarkers.
