[The microbiological diagnosis in severe infections]

Area of Science:

• Clinical microbiology
• Analytical chemistry
• Infectious disease diagnostics

Background:

• Traditional microbiological diagnosis relies on sensitivity and specificity.
• Serious infections necessitate a third criterion: rapid identification of the causative agent and antimicrobial susceptibility.
• Existing diagnostic methods have lagged behind biochemical and hematological tests in speed.

Discussion:

• Ultrafast techniques, such as soft ionization mass spectrometry, can rapidly detect bacterial, fungal, and yeast proteins.
• These advanced methods offer significant gains in clinical settings.
• Early and effective antibiotic administration is crucial in critical care areas.

Key Insights:

• Mass spectrometry enables swift identification of microbial proteins, accelerating diagnosis.
• Faster results lead to reduced hospitalization durations.
• Improved patient management and cost reduction are direct benefits of rapid diagnostics.

Outlook:

• Potential for widespread adoption in intensive care units (ICUs), pediatric ICUs, and infectious disease units.
• Decreased waiting times for emergency department patients.
• Further integration of ultrafast techniques into routine clinical microbiology workflows.
