Antimicrobial stewardship: application in the intensive care unit.

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Pharmacology

Background:

• Critical-care units (CCUs) are crucial for evaluating appropriate antimicrobial use.
• Empirical antimicrobial therapy is vital for treating infections in CCUs but carries significant risks.
• Broad-spectrum antibiotic regimens, while often necessary, can lead to adverse events like Clostridium difficile infection and antimicrobial resistance.

Purpose of the Study:

• To highlight the importance of antimicrobial stewardship in critical care.
• To emphasize the need for judicious use of broad-spectrum antibiotics.
• To guide the implementation and expansion of antimicrobial stewardship programs.

Main Methods:

• Review of current practices in antimicrobial therapy within critical care settings.
• Discussion of pharmacokinetic-pharmacodynamic principles in antibiotic dosing.
• Emphasis on the role of trained pharmacists and physicians in stewardship.

Main Results:

• Broad-spectrum empirical therapy must be necessary, appropriately dosed, and discontinued when no longer indicated.
• Antimicrobial stewardship interventions are essential for managing complex antibiotic use.
• Stewardship programs can focus on initiating, expanding, or proposing future research.

Conclusions:

• Optimizing antimicrobial use in CCUs is critical for patient outcomes.
• Antimicrobial stewardship programs are key to mitigating risks associated with antibiotic therapy.
• Collaboration between pharmacists and physicians is vital for effective stewardship.
