Question 3 of our JMO pre-test survey asked about the aims of antimicrobial stewardship (yes, better ‘antimicrobial’ than ‘antibiotic’- antiviral, antifungal, antiparasitic resistance are issues as well). We gave you three options and all except one responded with the correct answer – all three! The order is important – treatment of the individual patient comes first:
- Optimise the effectiveness of individual patient antimicrobial treatment for infection (implies that the right patients are identified for treatment and that correct treatment and follow-up occurs)
- Improve patient safety by reducing unintended consequences of antimicrobial treatment (implies that we know our guidelines, our drugs and our patients well)
- Ecology – reduce antimicrobial resistance by reducing antibiotic selective pressure on micro-organisms (selective pressure arises from any a/m exposure; prolonged courses and/or broader spectrum agents worse ; unnecessary use also critical – humans who have not ‘earned’ their antibiotics, and many situations across agriculture and food production)
The global antimicrobial resistance dilemma we face is truly a ‘Tragedy of the Commons‘ :
“A dilemma arising from the situation in which multiple individuals, acting independently and rationally consulting their own self-interest, will ultimately deplete a shared limited resource, even when it is clear that it is not in anyone’s long-term interest for this to happen.”
Cooperative stewardship of the resource required. Technical solutions (e.g. finding a new antibiotic) alone won’t solve it!
