Fast Track Diagnostic Tools for Clinical Management of Sepsis: Paradigm Shift from Conventional to Advanced Methods

Area of Science:

• Medical Microbiology
• Infectious Diseases
• Clinical Diagnostics

Background:

• Sepsis remains a leading cause of mortality, complicated by diagnostic challenges and the rise of antimicrobial resistance (AMR).
• Accurate and timely identification of pathogens and their resistance profiles is crucial for effective sepsis management and combating AMR.
• Conventional blood culture methods for sepsis diagnosis are time-consuming and can yield false negatives, especially with pre-treated samples or slow-growing organisms.

Purpose of the Study:

• To review the transition from conventional to modern diagnostic technologies for bloodstream infections and AMR detection.
• To highlight the advantages and limitations of current and emerging diagnostic approaches for sepsis.

Main Methods:

• Literature review of conventional and modern diagnostic techniques for sepsis and AMR.
• Comparative analysis of diagnostic accuracy, speed, and limitations.

Main Results:

• Conventional blood cultures are slow and have limitations, particularly with antibiotic pre-treatment.
• Modern diagnostic methods provide faster and more accurate pathogen identification and AMR quantification.
• Advanced technologies offer significant improvements in diagnosing sepsis and guiding antibiotic therapy.

Conclusions:

• A shift towards modern diagnostic technologies is essential for prompt and accurate sepsis diagnosis and effective AMR surveillance.
• Advanced diagnostics facilitate targeted antibiotic administration, improving patient outcomes and aiding in the fight against antimicrobial resistance.
