Empirical guidance on the management of infection in primary care in adults
Empirical Guidance on the Management of Infection in Primary Care in adults
♦To provide a simple, best guess approach to the treatment of common infections. ♦To minimise the emergence of bacterial resistance in
the community ♦
To promote the safe, effective and economic use of antibiotics
Principles of treatment
1. This guidance is based on the best available evidence but professional judgment should be used and patients should be involved in the
2. Antibiotics should be reviewed based on culture results. 3. A dose and duration of treatment for adults is suggested but may need modification for age, weight, height and renal function, always check
for hypersensitivity history. In severe or recurrent or complicated cases send samples for microbiology and consider a larger dose or longer course. All treatments are oral or topical unless specified. Please refer to BNF for further dosing and interaction information.
4. Prescribe an antibiotic only when there is likely to be a clear clinical benefit. 5. There is a lower threshold for antibiotics in immunocompromised or those with multiple morbidities; consider culture and seek advice. 6. Consider a no, or delayed, antibiotic strategy for acute sore throat, common cold, acute cough and acute sinusitis. 7. Limit prescribing over the telephone to exceptional cases 8. Use simple generic antibiotics if possible. Avoid broad spectrum antibiotics (e.g. co-amoxiclav, quinolones and cephalosporins) when narrow
spectrum antibiotics remain effective, as they increase the risk of Clostridium difficile
, MRSA, ESBLs and other resistant organisms.
9. Avoid widespread use of topical antibiotics (especially those agents available as systemic preparations (eg fusidic acid) 10. Please refer to BNF for update on antibiotics in pregnancy and in breast feeding, take specimens to guide treatment , AVOID tetracycline’s,
quinolones or high dose metronidazole (2g) unless specialist advice.
11. Where a "best guess" therapy has failed or special circumstances exist, microbiological advice can be obtained on 01908 243106/3404 12. Penicillin allergy: please take proper history and distinguish between anaphylaxis, just rash and intolerance. Important to inform patients
and include in any letter to other healthcare workers.
Upper Respiratory Tract Infections: Consider delayed antibiotic Prescriptions and Patient Information Leaflet
Annual vaccination is essential for all those at risk of influenza.
For otherwise healthy adults, the use of antivirals is not
recommended. Treat "at risk" patients only when influenza is circulating in the community, within 48 hours of start of symptoms. At risk: pregnant (including up to two weeks post partum), those 65 years or over, chronic respiratory disease including asthma & COPD, significant cardiovascular disease (not hypertension), immunocompromised, diabetes mellitus, chronic neurological, renal or liver disease. Patients over 13 years use oseltamivir 75mg oral capsule BD unless pregnant or there is resistance to oseltamivir, then use zanamivir 10mg (2 inhalations by diskhaler) and seek advice. For patients 13 years and under – seek further advice from the HPA Antivirals may be used for post-exposure prophylaxis during localized outbreaks in at risk people living in long-term residential or nursing homes on advice from the HPA/local microbiologist. (see NICE Influenza http://guidance.nice.org.uk/TA158)
Majority of sore throats are viral; Avoid antibiotics as 90% resolve in 7 days without and pain is only reduced by 16
Patients with 3 or 4 centor criteria (Hx of fever, purulent tonsils, cervical adenopathy, absence of cough) have a 40%
chance of Group A Beta Haemolytic Streptococci (GABHS) infection and wil benefit more from antibiotics, for these patients,
consider offering a 2 or 3 day delayed prescription or immediate prescription NICE Clinical guideline 69

Lower Respiratory Tract Infections
Note: Avoid tetracyclines in pregnancy. Low doses of penicillins are more likely to select out resistance. The quinolones (ciprofloxacin
and ofloxacin) should not be used 1st line as they have poor activity against pneumococci. Reserve all quinolones including
levofloxacin for PROVEN resistant organisms. Bronchiectasis infective exacerbations: please see Map of Medicine.
Antibiotics have marginal benefits in healthy adults.
Reserve use for patients with co-morbidities, consider 7-14
day delayed antibiotic (from symptom onset) with advice,
i.e. patient leaflet, and explain symptom resolution can take Doxycycline

Urinary Tract Infections
Note: People >65 years: do not treat asymptomatic bacteriuria; it occurs in 25% of women and 10% of men and is not associated with
increased morbidity. In the presence of a catheter, antibiotics will not eradicate bacteriuria and treatment may cause harm; only treat if
systemically unwell or pyelonephritis likely. Do not use prophylactic antibiotics for catheter changes unless history of catheter –change associated UTII/
sepsis. Amoxicillin should not be used empirically as resistance is over 50% locally.
In women with severe or with 3 or more symptoms treat. In
UTI in women
women with mild or 2 or less symptoms, use urine dipstick
to exclude UTI. (-ve nitrite, leucocyte and blood gives 76%
negative predictive value.) In women <65, cloudy urine, or

either blood or leucocytes has
92% positive predictive value), indicates treatment.

STI, symptomatic partner) to REACH sexual health services 0300 3038273 or Brook 0808 8021234 for screening and advice.
All topical and oral azoles give 75% cure.
In pregnancy, avoid oral azole, use intravaginal product
A 7 day course of oral metronidazole is slightly more
effective than 2g stat. Avoid 2g stat dose in pregnancy and
Topical treatment gives similar cure rates but is more
expensive. Treating partners does not reduce relapse.
Treat patient & refer to Sexual Health for follow up and
In pregnancy or breastfeeding, azithromycin is most
effective, but use is “off-label”. Tetracyclines are
contraindicated in pregnancy. Due to lower cure rate in
pregnancy, test for cure 6 weeks after treatment.
Could be due to STD infections or enteric pathogens.
Appropriate samples need to be taken –MSU, samples for
Chlamydia & Gonococcus if appropriate.
Refer to sexual health if due to STDs or under 35 years of

treatment may prevent chronic infection. Quinolones are
more effective due to greater penetration into prostate.
Refer to Sexual Health. Treat partners simultaneously.
In pregnancy or breastfeeding, avoid 2g single dose
metronidazole. Topical clotrimazole gives symptomatic
relief (not cure), consider if metronidazole declined.
Essential to test for N. gonorrhoea (increasing antibiotic
resistance), chlamydia and other organisms. Refer patient
to Sexual Health for follow up and contact tracing.
If severe disease or if high risk of gonorrhoea eg partner has it, sex abroad, severe symptoms, multiple partners refer for IM Ceftriaxone.
Uncomplicated infection only, for complicated cases seek
Consider co-infection with Chlamydia & Gonococcus
Patients need to be referred to Sexual Health for full STD screen and follow up.
Skin / Soft Tissue Infections
Panton-Valentine Leukocidin (PVL) is a toxin produced by 2% of Staph. Aureus
(positive in MRSA & MSSA). It is associated with persistent
recurrent pustules and carbuncles or cellulitis. Send swabs for bacterial culture with request for PVL detection in these clinical scenarios. On
rare occasions it causes severe invasive infections, even in fit people. Risk factors include: close contact environments, contact sport, sharing
equipment, poor hygiene, travel and compromised skin integrity. MRSA
Contact CHS Infection Control Team for advice on decolonization strategy. If active infection confirmed by laboratory, use
sensitivities to guide treatment. If severe infection or no response to appropriate monotherapy from sensitivities after 48 hours,
For extensive, severe or bullous impetigo use oral
As resistance is increasing reserve topical antibiotics for
very localised lesions. Reserve mupirocin for confirmed
Mupirocin MRSA only
Using antibiotics or adding them to steroids in eczema encourages resistance and does not improve healing unless there are visible signs of infection. In infected eczema use treatment as in impetigo. See local Guidance on Infected Eczema.
If patient afebrile and healthy other than cellulitis,
flucloxacillin may be used as single drug treatment. If
wound has been exposed to non-chlorinated water, (river,
lake or sea) discuss with microbiologist.
If febrile and ill, admit for IV treatment.
STOP IF DIARRHOEA
In facial cellulitis only, use co-amoxiclav to cover
from buccal microbes.
Bacteria will always be present. Antibiotics do not improve healing unless active infection.
Send properly taken culture
to empirical therapy. Antibiotics are only indicated if there is evidence of clinical cellulitis; increased pain;
enlarging ulcer, purulent exudate, foul odour or pyrexia. Treat as cellulitis above, refer to tissue viability team.
Review antibiotics after culture results
Refer for specialist opinion if severe infection

70% respond to metronidazole in 5 days; 92% in 14 days.
Severe if temp>38.5, WCC>15, rising creatinine or
signs/symptoms of severe colitis, need hospital admission.
Ensure patient is adequately re-hydrated. Cases who
relapse may require tapering dose of antibiotic – discuss
with Consultant Microbiologist and CHS IPC Team
Only consider standby for people travelling to remote areas and for people in whom an episode of infective diarrhoea could be
dangerous. If appropriate a PRIVATE prescription for Ciprofloxacin 500mg BD for 3 days can be supplied. In areas of high
ciprofloxacin resistance (Asia), consider prophylactic bismuth subsalicylate (Pepto Bismol) 2 tablets QDS or for 2 days as treatment, this can be brought OTC. Patients developing diarrhoea should be advised to see a local doctor if no improvement or symptoms get worsen’’
