TARGET Antibiotics
“There are few public health issues of potentially
greater importance for society than antibiotic
resistance”
2013 CMO Prof Dame Sally Davies
What do GPs think?
UK research suggests
– GPs recognise the wider importance of resistance
– Not a problem in their practice
– Believe hospitals/other prescribers e.g. vets also
main contributors to resistance
BUT
80% of antibiotics are prescribed in primary care
Simpson et al. J. Antimicrob. Chemother. (2007) 59 (2): 292-296
AIMS
● Why we need optimised prescribing
– Provide evidence showing the link between
prescribing and resistance in GP patients
● How we can improve antibiotic prescribing
– Suggest strategies and sharing materials

EVIDENCE
Reflection
In general practice
● Antibiotic resistance is clinically relevant
● Antibiotic resistance is increasing
● Antibiotic use increases antibiotic resistance
● Your prescribing influences resistance
● Antibiotic use also increases Clostridium difficile
Presentation Outline
● The evidence
● UK Prescribing
– How are we doing?
● The Patient Perspective
● Possible answers
Antibiotic prescribing is related to
consultation rates
– Consultation rate for RTI varies:125–1100 per 1000 patients
– Antibiotics prescribed in 45% to 98% of patients with RTI
– Consultation rates related to prescribing
– Practices who reduced prescribing experienced a reduced
consultation rate
Thus patients can be retrained not to expect antibiotics

● The patient perspective
– Why do they visit
– Expectation for antibiotics
– Is delayed prescribing a worthwhile option?

The Patient Perspective
What did they do?
1,767 ≥15y in England

took extra rest
20%
Contacted or visited GP surgery
6%

McNulty, Nichols, French et al. BJGP . (2012)
The Patient Perspective
Why they visited their GP with an RTI?
51%
Symptoms severe
47%
Symptoms not improved after several days
14%
family or friends suggestion
11%
Other health problem
9%
I usually visit GP with these symptoms
5%
Worried will infect others who may get very ill
What did they expect?
53·1% Expected antibiotics
24% Advice about self-care
22% Other treatment for symptoms
12% Rule out more serious illness
7% Information about illness duration
6% A sick/fit note for work
3% For referral to hospital/specialist
3% For Tamiflu
POSSIBLE ANSWERS
Improving patients confidence to self-care
Eurobarometer findings:
– 53% with good knowledge vs 21% with poor knowledge
remember receiving information about NOT taking
antibiotics
– 28% UK respondents remembered information from
their doctor or TV, 20% from a poster
– 90% UK respondents said they would use GP as a
trustworthy source of antibiotic information
It’s worth talking about antibiotics in consultations
Eurobarometer: Nov Dec 2009
The Patient Perspective
What did they do?
IPSOS Mori Survey
1,767 random sample >16 yrs, England
26% asked GP for antibiotics for any
condition in last year
96.5% Given antibiotic
3.5% Refused
antibiotic by GP
• 74% after discussion
• 23% immediately
