Individualized Approaches Are Needed for Optimized Blood Cultures.

Area of Science:

• Clinical diagnostics
• Microbiology
• Laboratory medicine

Background:

• Blood culture (BC) diagnostics are crucial for identifying bloodstream infections.
• Numerous strategies and technologies exist to enhance BC accuracy and speed.
• Optimal BC approaches are institution-specific, requiring tailored assessments.

Purpose of the Study:

• To provide strategies for optimizing blood culture diagnostics in individual laboratories.
• To emphasize the importance of preanalytical, analytical, and postanalytical process improvement.
• To guide institutions on implementing new BC technologies effectively.

Main Methods:

• Review of existing blood culture diagnostic workflows.
• Analysis of factors influencing diagnostic optimization (e.g., resistance rates, antibiotic use).
• Discussion of cost-neutral benefits through process enhancement.

Main Results:

• Preanalytical, analytical, and postanalytical optimization is essential before adopting advanced diagnostics like MALDI-ToF MS.
• Local factors such as resistance patterns and antibiotic prescribing significantly impact BC strategy.
• Creative use of existing tools can yield significant benefits.

Conclusions:

• Institutions should prioritize optimizing current blood culture systems and processes.
• Cost-effective improvements can be achieved by refining existing strategies.
• New high-technology diagnostics should be implemented thoughtfully to maximize impact.
