What was the world like before antibiotics?
• Before introduction of antibiotics (1940s), it was “normal” for patients in the UK to die from sepsis, endocarditis, etc.

What are we using antibiotics for?
• In England, 74% of human antibiotics are prescribed in general practice (ESPAUR report, 2016)
• The majority are prescribed for minor self limiting conditions
• 20% of antibiotics prescribed in UK primary care are unnecessary

Optimising use of antimicrobials
• Optimal use of antimicrobials in
– humans
– animals and agriculture
– Target: Reduce UK antibiotic use in food-producing animals by 25% between 2016 and 2020 and define new objectives by 2021 for 2025

![Page 28: Antimicrobial resistance UK national policy · Antimicrobial resistance UK national policy Dr Merlin Willcox DPhil MRCGP, Academic Clinical Lecturer, Department of Primary Care and](https://reader036.vdocuments.us/reader036/viewer/2022070814/5f0df04e7e708231d43cd2f3/html5/thumbnails/28.jpg)
How to reduce use of antibiotics in animals?• Use for growth promotion is now banned in the UK
• Increasing use of vaccines
• Targeted treatment to eradicate disease
– E.g. eradication of enzoonotic pneumonia from 6 large pig herds (5000 sows)
– Avoids need to treat the 125 000 piglets produced each year
– Average antibiotic use reduced from 120mg/kg to 30mg/kg

Investing in innovation, supply and access
• Sustainable investment in basic research
• Development of new therapeutics
• Wider access to therapeutics for those who need them
• Development of, and access to, diagnostics
– Target: Be able to report on % of prescriptions supported by a diagnostic test or decision support tool by 2024

Sore throat: test or decision support tool?
• Targeted use of antibiotics for acute sore throat with a clinical score (FeverPAIN) improves reported symptoms and reduces antibiotic use.
• Antigen tests have no clear advantages over a clinical score alone.
• Little et al, BMJ 2013.33
