‘I think I need antibiotics, doctor!’
Have you heard this opening gambit too often? Well fear not, it is time to wrestle back control of your prescription pad. The evidence in our favour is reaching Everest-like dimensions, the bells have started tolling for antibiotics in modern medicine and, furthermore, evidence shows that helping to save antibiotics can also help save our appointments.
At the end of a multi-problem 10-minute appointment it is easy to feel overwhelmed. Let’s face it, printing a script can seem substantially quicker than having an ‘antibiotic chat’, and saving antibiotics doesn’t make the slightest difference to QOF, DES or our ever-dwindling practice income. But research shows that prescribing fewer antibiotics may reduce the number of future consultations we might unwittingly perpetuate for self-limiting viral illness.
The world is running out of antibiotics. In the first thirty years after the discovery of penicillin, twenty different classes were discovered, but since 1962 only two more classes have been brought to market; the golden age of antibiotic discovery is over. MRSA is now widespread, particularly in the USA, and resistance among the Gram negative bacteria is the latest worry. Even Carbapenem resistant bacteria are increasing, and in 2009 a new superbug plasmid was discovered in India. This codes for an enzyme called NDM-1, which can confer resistance to several antibiotic classes at once. A ‘post-antibiotic era’ looms.
There is an important new movement in medicine to combat this – Antibiotic Stewardship. But what can GPs do? Guidelines are at hand. The Centor criteria help for sore throat: not to prescribe unless we find at least three out of fever, exudate, lymphadenopathy, and absence of cough, and the RCGP has developed the ‘TARGET’ toolkit with a link to Public Health England quick reference guides, CPD training resources, a patient information leaflet in different languages and, if you need an audit for your appraisal, there is one ready to do on your own practice’s antibiotic prescribing.1
I’d also like to briefly highlight a few key points myself. Firstly, remember a dry viral cough with no fever or other signs of serious illness can last up to eight weeks, and 80% of sinusitis improves spontaneously in two weeks. In children it can be common in viral illness to hear wet sounding crepitations on auscultation, and the NICE Traffic light system should always be used to assess for signs of more serious illness.
Secondly, for skin infections, remember I&D without antibiotics works for boils. If boils are recurrent, rather than giving repeated courses, don’t forget to test for MRSA or PVL carriage, with skin and nasal swabs. For cellulitis do be aware that Flucloxacillin covers both Staph and Strep, but remember to always give sufficient doses in adults of 500mg QDS for five to seven days.
Thirdly, in women with symptoms of UTI a negative dipstick makes bacterial infection unlikely, and for recurrent UTI in non-pregnant women there is still no clear evidence, but consider appropriate post-coital or standby antibiotics to try to reduce resistance.
Importantly there is also now evidence against ‘delayed prescribing’. A recent Cochrane review concluded that, in patients with respiratory infections where clinicians feel it is safe not to prescribe antibiotics immediately, no antibiotic prescription with advice to return if symptoms do not resolve is likely to result in the least antibiotic use, while maintaining similar clinical outcomes to delayed antibiotics.
In the future we may need something to replace antibiotics, but such research is in its infancy. I no longer feel disempowered when a patient tries to emphasize their impending holiday or work deadlines to try and get antibiotics. I explain that antibiotics may run out in their lifetime. And that every time we use them, we are using them up. I assess them at that point in time, and if they are not clinically unwell I explain in different ways that if they deteriorate it is much better medicine for them to have a repeat assessment. It seems only a matter of time before antibiotics run out for all of us. We can’t yet predict whether these crown jewels of medicine will still work in another two decades, and our own Chief Medical Officer has warned of a ‘catastrophic threat’. But we all have the power to slow the tsunami of resistance. And we might just save some more appointments too.
