Concept
Antimicrobial stewardship
Coordinated effort to optimize antimicrobial use
High-yield clue
Stewardship promotes appropriate antimicrobial use (right drug, spectrum, and duration) to slow resistance emergence.
Overview
Antimicrobial stewardship is a coordinated set of efforts to improve appropriate use of antimicrobials, aiming to slow resistance and preserve drug effectiveness. It is a central public-health response to antimicrobial resistance.
Classification
- Public-health concept
- Antimicrobial-resistance countermeasure
- Coordinated program framework
Lab & identification clues
- De-escalation and narrowing spectrum based on susceptibility data
- Susceptibility testing (Kirby-Bauer, MIC) guides appropriate use
- Avoiding unnecessary antimicrobial exposure reduces selection pressure
Associations
- Directly counters MRSA, VRE, ESBL, and CRE spread
- Links to infection prevention and surveillance
- WHO/CDC frame stewardship as core AMR strategy
Commonly confused with
- Stewardship vs infection control
- Empiric vs targeted use
