Diagnostic Stewardship Cuts Testing in Sick Infants
Clinical decision support reduced potentially unnecessary respiratory cultures in critically ill children without evidence of patient harm
Clinical Scorecard: Diagnostic Stewardship Cuts Testing in Sick Infants
At a Glance
Category Detail
Condition Ventilator-associated infections Key Mechanisms Clinical decision support tools to standardize testing practices Target Population Infants in pediatric intensive care units (PICUs) Care Setting Pediatric intensive care units (PICUs)
Key Highlights
16% reduction in respiratory culture use across 15 US PICUs No adverse patient outcomes observed post-implementation based on study findings Standardized testing reduced unnecessary microbiology investigations Positive cultures may indicate colonization rather than infection Variable effectiveness noted across different centers Guideline-Based Recommendations
Diagnosis
Implement clinical decision support to guide testing for ventilator-associated infections based on study findings Management
Discourage testing in patients unlikely to have a ventilator-associated infection based on study findings Monitoring & Follow-up
Assess the impact of reduced testing on clinical outcomes such as length of stay and readmissions based on study findings Risks
Potential for overdiagnosis and unnecessary antibiotic treatment from positive cultures based on study findings Patient & Prescribing Data
Infants receiving mechanical ventilation in PICUs
Antibiotic use remained broadly unchanged despite reduced testing
Clinical Best Practices
Utilize checklists or algorithms to standardize indications for respiratory culture collection Evaluate local practice and implementation for effectiveness of stewardship programs Further research needed to integrate stewardship into routine workflows based on study findings Related Resources & Content
