If score 3 there is a 40% probability of bacterial infection use 3-day back up antibiotics if 4 or more then use immediate antibiotics if severe or 48 hour short back-up prescription. Consider 2 or 3-day-delayed or immediate antibiotics for pain relief if: < 2yrs AND bilateral AOM (NNT4) or bulging membrane & 4 marked symptoms All ages with otorrhoea (NNT3) Antibiotics to prevent Mastoiditis NNT >4000 First use analgesia and aural toilet (if available) as may not be infective. If cellulitis or disease extending outside ear canal, swab and start oral antibiotics and refer to exclude malignant otitis externa. Avoid antibiotics as 80% resolve in 14 days without treatment, and they only offer marginal benefit after 7 days NNT 15 Use adequate analgesia Consider 7-day-delayed or immediate antibiotic when purulent pharyngeal discharge NNT8 Antibiotic little benefit if no co-morbidity.

This summary guideline accompanies NHS Rotherham CCG: Management of Infection in Primary Care 2017-19 and is available at http://www.rotherham.nhs.uk/clinicians/guidelines.htm The guidance in both is based on the best available evidence but its application must be modified by professional judgement. 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 consideration of a larger dose or longer course may be necessary. This Communication was issued in partnership by NHS Rotherham CCG and Rotherham NHS Foundation Trust
ANTIMICROBIAL SUMMARY PROTOCOL F THE MANAGEMENT OF INFECTION OF PRIMARY CARE 2017 2019 Next review due December 2019 NHS This summary protocol has been produced using the NHS Rotherham CCG full protocol on Management of Infection in Primary Care 2017 2019 and is largely based on the HPA Management of Infection Guidance for Primary Care for local adaption. KEY PRINCIPLES OF ANTIMICROBIAL PRESCRIBING 1. Only prescribe antibiotics where there is evidence of a bacterial infection and there is likely to be a clear clinical benefit and in severe infections initiate antibiotics as soon as possible. 2. Do not prescribe an antibiotic before checking previous microbiology results to determine the patient s usual isolates and sensitivities if there is a chronic underlying condition and/or to make sure the patient has not grown MRSA, ESBLs (Extended Spectrum Beta-lactamase producers) or clostridium difficile since these isolates will Influence your antibiotic choice. 3. Check for hypersensitivity and allergy status determine if genuine and document description clearly and the severity of it if not documented already. 4. Use simple, well established, generic narrow spectrum antibiotics where possible and they remain effective. Avoid broad spectrum agents (e.g. coamoxiclav, quinolones and cefalosporins) as they increase the risk of c. difficile, MRSA and resistant UTIs. 5. NHS Rotherham guidelines suggest a dose and duration for empiric treatment; however in severe cases a larger dose or longer course may need to be considered. If in doubt contact Microbiology for advice. 6. Consider a no or delayed antibiotic strategy for acute self-limiting upper respiratory tract infections and urinary tract infections when appropriate 7. Antibiotics are ineffective against viral sore throats, simple coughs and colds. 8. Ensure the clinical indication, dose, route and duration of antibiotics is clearly documented in the patient s medical records. 9. Avoid the use of topical antibiotics, especially those that are available for systemic use (e.g. fusidic acid); this practice tends to compromise their effectiveness since it selects for resistance. 10. Limit prescribing of antibiotics over the telephone to exceptional cases ONLY. 11. Avoid longer courses of treatment than necessary. 12. Lower threshold for antibiotics in immunocompromised or those with multiple morbidities; consider culture and seek advice. 13. Avoid unnecessary use of combinations of antimicrobials where a single drug would be equally effective. 14. Avoid prophylactic use of antibiotics unless of proven benefit. 15. Clarithromycin has a better side-effect profile than erythromycin, greater compliance as its dose is twice rather than four times daily & generic tablets are similar cost and may be a suitable alternative where specifically mentioned. In children erythromycin may be preferable as clarithromycin syrup is twice the cost. Where best guess or empirical therapy has failed (including any determined through culture and sensitivity) or special circumstances exist, specialist Microbiologist advice can be obtained from Rotherham Foundation Trust (RFT.) Consultant Microbiologist 01709 304742 / 307712 Microbiology lab 01709 304242 or via RFT Switchboard 01709 82000 bleep no. 280. PENICILLIN ALLERGY Allergy Status Always ask for description of the reaction experienced. Document in notes and the Name of medicine and the reaction. Diarrhoea is a result of change in bowel flora and not an allergic reaction True penicillin-allergic patients will react to all penicillins. About 10% of penicillin-sensitive patients will also be allergic to cephalosporins. Where patients are penicillin allergic, use clarithromycin in place of the penicillin agent (unless an alternative is specified in the guideline or seek advice from microbiologist on suitable alternatives). DENTAL / AL INFECTIONS GPs should not routinely be involved in dental treatment and, if possible advice should be sought from the patient s dentist, who should have details of how to access treatment out-ofhours, or telephone 111 for (NHS 111 service) This summary guideline accompanies NHS Rotherham CCG: Management of Infection in Primary Care 2017-2019 and is available at http://www.rotherhamccg.nhs.uk/therapeutic-guidelines.htm The guidance in both is based on the best available evidence but its application must be modified by professional judgement. 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 consideration of a larger dose or longer course may be necessary. This Communication was issued in partnership by NHS Rotherham CCG and Rotherham NHS Foundation Trust MRSA Use cultures to confirm MRSA infection. For active MRSA infection use antibiotic sensitivities to guide treatment. If severe infection or no response to monotherapy after 24-48 hours, seek advice from microbiologist on combination therapy. Patient s with MRSA should have an alert attached in their clinical record in active/current problems, as once a patient has been identified as MRSA positive the risk of clinical infection remains throughout their life. MRSA is resistant to Beta-lactam Antimicrobials such as flucloxacillin, coamoxiclav, cephalosporins and other agents such as ciprofloxacin and any future courses of antibiotics should be prescribed with care. MRSA READ codes: EMIS: A3B11 Systm One: XE0R6 ANTIBIOTIC ASSOCIATED DIARRHOEA CLOSTRIDIUM DIFFICLE INFECTION C. Diff Infection (CDI) may manifest whilst on antibiotics, but a significant number of cases occur following cessation of therapy, the incubation period extending to several weeks. Symptoms may include fever, abdominal pain and diarrhoea (with/without blood and or mucus). Antibiotics particularly associated with CDI include broad spectrum agents such as co-amoxiclav, cephalosporins, quinolones (including ciprofloxacin) and clindamycin (the 4C antibiotics ). Any patient with an antigen GDH positive but toxin-negative result should be treated (as below) if the diarrhoea is otherwise unexplained and persists. Patient s with a CDI should have an alert attached in their clinical record in active/current problems, as once a patient has been infected with a CDI or has been identified as antigen GDH positive and C.Diff toxin negative the risk of clinical infection remains throughout their life. C.Diff Infection (CDI) READ Code:EMIS/Systm One:A3Ay2 GDH +ve READ code: EMIS: 43k90 Systm One: XaaaT Stop unnecessary antibiotics and/or PPIs. 70% respond to metronidazole in 5 days; 92% in 14 days If severe symptoms or signs (below) should treat with oral vancomycin, review progress closely and/or consider hospital referral. Admit if severe: Temp>38.5 o C; WCC >15, rising creatinine or signs/symptoms of severe colitis
ANTIMICROBIAL SUMMARY PROTOCOL F THE MANAGEMENT OF INFECTION OF PRIMARY CARE 2017 2019 Next review due December 2019 NHS LOWER RESPIRATY TRACT INFECTIONS Note: Low doses of penicillin s are more likely to select out resistance. Do not use quinolones (ciprofloxacin, ofloxacin) first line due to poor pneumococcal activity. Reserve all quinolones (including levofloxacin) for proven resistant organisms. COUGH, BRONCHITIS Antibiotic little benefit if no co-morbidity Symptom resolution can take 3 wks. Consider 7 day delayed antibiotic with symptomatic advice/leaflet Consider immediate antibiotics if > 80yr and ONE of: Hospitalisation in past year, oral steroids, diabetic, congestive heart failure > 65yrs with 2 of the above. COMMUNITY-ACQUIRED PNEUMONIA TREATMENT IN THE COMMUNITY Use CRB-65 score to help guide and review: Score s should not substitute clinical judgement i.e. signs of fever, cough, sputum, new focal chest signs etc. See BTS guidelines for full details Each scores 1: Confusion (AMT< 8) ; Respiratory rate 30/min; BP systolic < 90 or diastolic 60; Age 65 MYCOBACTERIAL INFECTIONS Infection control risk for appropriate isolation and infection control precautions: Refer to Consultant Chest Physician and Infection control team via Rotherham Foundation Trust switchboard 01709 820000 Advice available from TB Specialist Nurse on Mon Thurs 9 am 5 pm 01709 423253 Self Limiting UPPER RESPIRATY TRACT INFECTIONS SE THROAT Avoid antibiotics as 90% resolve in 7 days without treatment, and pain only reduced by16 hours OTITIS MEDIA (AOM) Optimise Analgesia and target antibiotics as 60% resolves in 24 hours without antibiotics, which only reduce pain at 2 days (NNT15) and does not prevent deafness RHINO-SINUSITIS Avoid antibiotics as 80% resolve in 14 days without treatment, and they only offer marginal benefit after 7 days NNT 15. Use adequate analgesia URINARY TRACT INFECTIONS People >65 years: do not treat asymptomatic bacteriuria in the absence of white cells or <10 5, CFU/ml; it is common but is not associated with increased morbidity unless pathogen isolate is MRSA. Typical UTI Symptoms: dysuria, urgency, frequency, polyuria, suprapubic tenderness, haematuria. Catheter in situ: antibiotics will not eradicate asymptomatic bacteriuria; only treat if systemically unwell or pyelonephritis likely Do not use prophylactic antibiotics for catheter changes unless history of catheter-change-associated UTI Risk factors for increased resistance include: care home resident, recurrent UTI, hospitalisation >7d in the last 6 months, unresolving urinary symptoms, recent travel to a country with increased antimicrobial resistance (outside Northern Europe and Australasia) especially health related, previous known UTI resistant to trimethoprim, cephalosporins or quinolones. If increased resistance risk, send culture for susceptibility testing & give safety net advice. If GFR<45 ml/min or elderly consider pivmecillinam 400mg TDS or fosfomycin (3g stat in women plus 2nd 3g dose in men 3 days later). STI SCREENING GENITAL TRACT INFECTIONS People with risk factors should be screened for chlamydia, gonorrhoea, HIV, syphilis. Refer individual and partners to GUM service. Risk factors: < 25y, no condom use, recent (<12mth) /frequent change of partner, symptomatic partner, area of high HIV. CONJUNCTIVITIS Most conjunctivitis is viral or self-limiting. Bacterial conjunctivitis is usually unilateral and also self limiting. It is characterised by red eye with mucopurulent, not watery discharge. Only treat if severe. 65% resolve on placebo by day five fusidic acid has less Gram-negative activity MENINGITIS Transfer all patients to hospital immediately. If time before admission, give IV benzylpenicillin unless hypersensitive, i.e. history of difficulty breathing, collapse, loss of consciousness, or rash. GIVE: IV or IM benzylpenicillin or cefotaxime (give IM if vein cannot be found) benzylpenicillin: Children <1 yr: 300 mg, Children 1-9 yr: 600 mg, Age 10+ years: 1200 mg cefotaxime :Children < 12 yrs: 50mg/kg, Children 12+ years: 1gram Prevention of secondary case of meningitis: Only prescribe following advice from: PHE South Yorkshire Health Protection Team Tel: 0114 321 177 Out of hours: 0114 304 9843 GASTRO- INTESTINAL TRACT INFECTIONS INFECTIOUS DIARRHOEA Refer previously healthy children with acute, painful or bloody diarrhoea to exclude E. coli 0157 infection. Antibiotic therapy not indicated unless systemically unwell. If systemically unwell and campylobacter suspected (e.g. undercooked meat and abdominal pain), consider clarithromycin 250 500 mg BD for 5 7 days if treated early. GASTROENTERITIS Antimicrobials usually NOT required. May be necessary in invasive salmonellosis. Seek advice from microbiology. Cases of food poisoning should be notified. TRAVELLER S DIARRHOEA Only consider standby antibiotics for remote areas or people at high-risk of severe illness with travellers diarrhoea Medical attention should be sought in the country of travel for assessment of whether antibiotics are required.
