Greater Manchester Antimicrobial Guidelines October2021

Aims
     •   to provide a simple, empirical approach to the treatment of common infections
     •   to promote the safe and effective use of antibiotics
     •   to minimise the emergence of bacterial resistance in the community

Principles of Treatment
1.   This guidance is based on the best available evidence, but use professional judgement and involve patients in
     decisions.
2.   Please ensure you are using the most up to date version. The latest version will be held on the GMMMG website.
3.   Prescribe an antibiotic only when there is likely to be a clear clinical benefit.
4.   When recommending analgesia or treatment with products available f rom pharmacies please follow the
     guidance issued by NHS England (Conditions for which over the counter items should not routinely be
     prescribed in primary care: Guidance for CCGs [Gateway approval number: 07851]). See the guidance for
     exceptions to recommending self-care.
5.   Consider a no, or delayed, antibiotic strategy for acute self -limiting infections e.g. upper respiratory tract
     infections.
6.   When prescribing an antibiotic it should be based on the severity of symptoms, risk of developing complications,
     previous laboratory tests and any previous antibiotic use.
7.   Limit prescribing over the telephone to exceptional cases. Except during COVID-19 pandemic where face-to-
     face contact should be minimised by using telephone or video consultations
8.   A dose and duration of treatment for adults is usually suggested, but may need modification for age, weight and
     renal function. In severe or recurrent cases consider a larger dose or longer course.
9.   Unless treatment choice is listed separately for children, then choices given are considered appropriate for
     adults and children; bearing in mind any specific age limitations for use listed in the BNF for Children. A link to
     the UK Paediatric Antimicrobial Guidelines can be found here
10. Lower threshold for antibiotics in immunocompromised or those with multiple morbidities; con sider culture and
    seek advice.
11. Use simple generic antibiotics if possible. Avoid broad spectrum antibiotics (eg co-amoxiclav, quinolones and
    cephalosporins) when narrow spectrum antibiotics remain effective, as they increase risk of Clostridiodes
    difficile, MRSA and resistant UTIs.
12. Where Off-label use is recommended: Prescribers should follow relevant professional guidance, taking full
    responsibility for the decision, and obtaining and documenting informed consent. See the GMC's Good practice
    in prescribing and managing medicines for more information.
13. Avoid widespread use of topical antibiotics (especially those agents also available as systemic pre parations,
    e.g. fusidic acid).
14. In pregnancy AVOID tetracyclines, aminoglycosides, quinolones and high dose metronidazole.
15. We recommend clarithromycin as the preferred macrolide as it has less side-effects than erythromycin, greater
    compliance as twice rather than four times daily & generic ta blets are similar cost. The syrup formulation of
    clarithromycin is only slightly more expensive than erythromycin and could al so be considered for children.
    Erythromycin remains the drug of choice in pregnancy and should be used where clarithromycin is indicated.
16. Always advise to seek medical help if symptoms worsen at any time or do not improve within 48 hours of starting
    an antibiotic or the person becomes systemically unwell.
17. Review antibiotic choice once culture and susceptibility results are available .
18. Wh e re an empirical therapy has failed or special circumstances exist, microbiological advice can be obtained
    f r om your local hos pital microbiology department.
19. This guidance should not be used in isolation; it should be supported with patient information about back-
    up/delayed antibiotics, infection severity and usual duration, clinical staff education, and audits. Materials are
    available on the RCGP TARGET website.
20. This guidance is developed alongside the NHS England Antibiotic Quality Premium (QP). In 2017/19 QP expects:
    at least a 10% reduction in the number of E. coli blood stream infections across the whole health economy; at
    least a 10% reduction in trimethoprim:nitrofurantoin prescribing rati o for UTI in primary care, and at least a 10%
    reduction in trimethoprim items in patients > 70 years, based on CCG baseline data from 2015/16; and sustained
    reduction in antimicrobial items per STAR-PU.
21. This guidance should be facilitated by the adoption of Antibiotic Stewards from front line to board level within
    organisations, in line with NICE NG15: Antimicrobial stewardship, August 2015 . This sets out key activities and
    responsibilities for individuals and organisations in responding to the concern of antimicrobial resistance.
22. Please note MHRA safety alert (issued 21 March 2019): Fluoroquinolone antibiotics: ciprofloxacin,
    levofloxacin,moxifloxacin, ofloxacin: New restrictions and precautions due to very rare reports of disabling and
    potentially long-lasting or irreversible side effects. Key details are below and referenced where the relevant
    antimicrobials are advised in the guideline. Full letter can be viewed at DDL_fluoroquinolones_March-
    2019_final.pdf.

URINARY TRACT INFECTIONS
As antimicrobial resistance and E. coli bacteraemia is increasing use nitrofurantoin first line. Always give safety net and s elf-care advice
and consider risks for resistance. Give the appropriate TARGET Treat Your Infection UTI leaflet.
Do not perform urine dipsticks – For men and women over 65 years
Dipsticks become more unreliable with increasing age over 65 years. Up to half of older adults, and most with a urinary catheter, will have
bacteria present in the bladder/urine without an infection. This “asymptomatic bacteriuria” is not harmful, and although it c auses a positive
urine dipstick, antibiotics are not beneficial and may cause harm.
For guidance on diagnosing UTIs and the need for dipsticks , in all ages, see PHE’s quick reference tool for primary care.
