Antibiotic resistance at patient level
Costelloe et al. BMJ 2010:340 c2090
Effect of antibiotic prescribing in primary care on antimicrobial resistance in individual
patients: systematic review and meta-analysis
Multidisciplinary
• Individuals prescribed an antibiotic in primary care for a respiratory or
urinary infection develop bacterial resistance to that antibiotic
• The effect is greatest in the month immediately after treatment but
may persist for up to 12 months
• This effect not only increases the population carriage of organisms
resistant to first line antibiotics, but also creates the conditions for
increased use of second line antibiotics in the community

Illness behaviour and antibiotic prescription in patients with respiratory

• The antibiotic revolution should be more focused...
• “Our mission is not to prescribe as few antibiotics as
possible, but to identify that small group of patients who
really need antibiotic treatment and to explain, reassure
and educate the large group of patients who don’t.”

An immediate antibiotic prescription and/or further appropriate
investigation and management should only be offered to patients (both
adults and children) in the following situations:
• Systemically very unwell
• Symptoms and signs suggestive of serious illness and/or complications
(particularly pneumonia, mastoiditis, peritonsillar abscess, peritonsillar cellulitis,
intraorbital and intracranial complications)
• High risk of serious complications because of pre-existing comorbidity
eg significant heart, lung, renal, liver or neuromuscular disease,
immunosuppression, cystic fibrosis, and young children who were born
prematurely

 History of congestive heart failure

• Does this information help you understand more clearly the
place in therapy of antibiotics in respiratory tract infections?
• Are there instances where you have treated patients out
with these criteria?

The benefits of antibiotics have to be carefully balanced against their harm
Most antibiotics can cause gastrointestinal effects such as nausea,

In addition, a number can cause serious rashes and skin reactions

Delayed antibiotics for respiratory infections.

•
Delayed prescriptions substantially reduce antibiotic use but might
slightly worsen some symptoms compared with immediate
prescriptions
•
Delayed prescriptions might also reduce re-consultation rates
•
For mild upper respiratory tract infections delayed prescriptions are
not associated with important negative consequences

Delayed prescriptions
Spurling et al. Cochrane Database of Systematic Reviews, Issue
4.Cochrane 2013
Delayed antibiotics for respiratory infections. Update of 2007
•
Most clinical outcomes show no difference between strategies
•
Delay slightly reduces patient satisfaction compared to
immediate antibiotics (87% versus 92%) but not compared to
none (87% versus 83%)
•
In patients with respiratory infections where clinicians feel it is
safe not to prescribe antibiotics immediately, no antibiotics with
advice to return if symptoms do not resolve is likely to result in
the least antibiotic use, while maintaining similar patient
satisfaction and clinical outcomes to delayed antibiotics

Delayed prescriptions
National Institute for Health and Clinical Excellence.
Respiratory tract infections – Prescribing of antibiotics for self-limiting
respiratory tract infections in adults and children in primary care. 2008.
(Clinical Guideline 69)
Multidisciplinary
When using delayed antibiotic prescriptions, patients should be offered:
• Reassurance that antibiotics are not needed immediately since likely to
make little difference to symptoms and may have side effects, for
example, diarrhoea, vomiting and rash
• Advice about using the delayed prescription if symptoms are not
starting to settle in accordance with the expected course of the illness or if
a significant worsening of symptoms occurs
• Advice about re-consulting if there is a significant worsening of
symptoms despite using the delayed prescription.
• A delayed prescription with instructions - either given to patient or left
at an agreed location to be collected at a later date.
