Antimicrobial Stewardship in the ICU

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Antimicrobial Stewardship

Background:

• Intensive care units (ICUs) face increasing infections and multidrug-resistant pathogens, necessitating effective antimicrobial stewardship.
• Antimicrobial overuse is common in ICUs, posing challenges for clinicians balancing empiric therapy with resistance concerns.

Purpose of the Study:

• To review key components of antimicrobial stewardship programs.
• To highlight mechanisms for critical care practitioners to share responsibility for antimicrobial stewardship in the ICU.

Main Methods:

• This review summarizes current antimicrobial stewardship principles and practices.
• It emphasizes the role of critical care clinicians in bedside stewardship initiatives.

Main Results:

• Stewardship goals now align with critical care objectives: optimizing patient outcomes, reducing resistance, and minimizing adverse events.
• Opportunities for stewardship at the bedside include judicious antimicrobial initiation, biomarker use, rapid diagnostics, pathogen screening, and de-escalation.

Conclusions:

• Integration of critical care practitioners into antimicrobial stewardship programs is essential for success.
• Critical care clinicians play a vital role in optimizing antimicrobial use to improve patient outcomes and combat resistance.
