Using antibiotics wisely

Area of Science:

• Infectious Diseases
• Antimicrobial Stewardship
• Artificial Intelligence in Medicine

Background:

• Optimizing antibiotic therapy is crucial for combating antimicrobial resistance and improving patient outcomes.
• Current practices often involve prolonged antibiotic durations and intravenous administration, which may not always be necessary.

Approach:

• Reviewing evidence for shorter antibiotic durations in conditions like Enterobacterales bacteremia, community-acquired pneumonia, and ventilator-associated pneumonia.
• Evaluating the safety and efficacy of switching from intravenous to oral antibiotic therapy for infections such as bacteremia, endocarditis, and bone and joint infections.
• Exploring the emerging role of artificial intelligence in antimicrobial stewardship.

Key Points:

• Shorter antibiotic regimens (e.g., 7 days for bacteremia, 3 days for community-acquired pneumonia) are non-inferior to standard durations.
• Early conversion to oral antibiotics is safe and effective, reducing complications and costs for various infections.
• Single-dose cefazolin is recommended for clean surgical procedures, emphasizing accurate allergy assessment.

Conclusions:

• Implementing shorter antibiotic durations and facilitating early intravenous-to-oral switch represent achievable strategies for antimicrobial stewardship.
• Artificial intelligence holds potential for automating and enhancing antibiotic use optimization, though further validation is required.
