Clinical Scorecard: Diagnostic Stewardship Cuts Testing in Sick Infants

At a Glance

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
