- 98% essential agreement and 94% categorical agreement for susceptibility testing.
- Testing from human blood spiked with specific bacterial isolates.
- Limitations include potential effects of prior antimicrobial exposure.
Guideline-Based Recommendations
Diagnosis
- Utilize sedimentation-assisted tandem rocking and enrichment for analysis.
Management
- Implement rapid identification and susceptibility testing for bloodstream pathogens.
Monitoring & Follow-up
- Assess bacterial recovery and growth in the context of prior antimicrobial exposure.
Risks
- Consider limitations in detecting fastidious or nonculturable organisms.
Patient & Prescribing Data
Patients with suspected bloodstream infections.
Rapid identification and susceptibility testing can inform timely treatment decisions.
Clinical Best Practices
- Incorporate rapid testing workflows in clinical settings for improved patient outcomes.
- Ensure validation of workflows in prospective studies with actual patient samples.
