    Introduction The antimicrobial treatment guidelines in both primary and secondary care have been designed to reduce patient’s exposure to antibiotics (quinolones, cephalosporins, clindamycin, co-amoxiclav) most likely to cause Clostridium difficile associated diarrhoea (CDAD). Adherence to these guidelines is therefore an extremely important aspect of preventing infection. However, all antibiotics may cause CDAD and some cases will still occur. Early diagnosis and treatment prevents complications, hospital admissions and saves lives. Clinical Symptoms

    Asymptomatic

    Watery diarrhoea (type 5-7)

    Fever

    Loss of appetite

    Abdominal pain/tenderness

    Nausea

    Stool has characteristic offensive smell /green appearance Diagnosis National guidance advises all cases of diarrhoea among people in the community aged 2 years or more should be investigated for CDI unless there are good clinical or epidemiological reasons not to1. If a patient has diarrhoea (Bristol Stool Chart types 5-7) that is not clearly attributable to an underlying condition or therapy (i.e. laxatives,) then it is necessary to determine if this is due to CDI3. A stool sample should always be collected if CDI is suspected. The possibility that the diarrhoea has an infectious cause should be considered, particularly where there is no clear alternative cause. See appendix 2 for medicines that can cause diarrhoea. Note: For patients on enteral feeding do not assume diarrhoea is due to therapy. Consider possibility of CDI as seen below. CDI should be suspected in patients with type 5-7 stools AND one or more of the following risk factors: o current or recent course of antibiotics (within last 4-12 weeks) o has a previous history of CDAD o > 65 years o has recently been a hospital inpatient (within last 3 months) o current anti-ulcer medication (e.g. omeprazole, lansoprazole & ranitidine) o nasogastric tube o immunocompromised (undergoing chemotherapy, cancer treatments, haematological diseases).

    Stool samples should take the shape of the container (Bristol stool types 5-7), as soon as CDI suspected. NB: solid stools will not be tested for CDI by the laboratory

    If a patient has a positive result for the CDI Toxin test and has symptoms of mild disease, they require prompt treatment with metronidazole, for 10-14 days, in primary care.

    Please note that stool samples can be GDH (Clostridium difficile) antigen positive, but toxin negative. This means that the patient has no active C. difficile infection but is carrying the antigen which has the potential to develop into CDI. Clinical treatment is only indicated if the patient is symptomatic with diarrhoea. It is important to reduce exposure to risk of CDI such as usage of antibiotics, anti- ulcer medication etc. in these patients.

    If the patient has diarrhoea and there is a strong clinical suspicion of CDI, treatment MUST be initiated without waiting for a positive toxin stool sample result. Further advice can be obtained from microbiology. Consider the clinical presentation.

    Once the diagnosis has been made, repeat samples are not required unless specifically requested by microbiology.

    Appendix 3 provides details of the Department of Health mandatory 2 stage testing procedure, and interpretation of results, for Clostridium difficile for more information.

    Management & Treatment For ALL patients on suspicion or confirmed CDI see below – please document any rationale for deviations from the advice outlined here.

    Discontinue current ‘unnecessary’ antibiotics to allow normal intestinal flora to be re-established. If this is not possible, discuss alternatives with a Consultant Microbiologist.

    Anti-motility drugs (e.g. codeine, loperamide) should be avoided in CDI (due to the risk of precipitating toxic megacolon – by slowing clearance of C difficile from intestine). Including those prescribed or bought over the counter.

    Stoma patients who require anti-motility drugs to maintain a normal stoma output should be discussed with the gastroenterologist.

    Review anti-ulcer drugs (e.g. PPIs & H2 antagonists) -stop or reduce dose if possible. Evidence indicates these are a risk factor for CDI (in particular PPIs). Consider the risk/benefit to the patient. If necessary Ranitidine may an alternative to PPI medication.

    Avoid prokinetic agents (e.g. metoclopramide, domperidone) as these may increase diarrhoea.

    Laxatives (e.g. lactulose, senna) are rarely indicated long term - stop in acute CDI.

    Non-steroidal anti-inflammatory drugs (e.g. ibuprofen, diclofenac) should be stopped in acute CDI.

    Review use of diuretics (e.g. furosemide, bendroflumethiazide, spironolactone) and ACE inhibitors/A2RAs (e.g. ramipril, lisinopril, losartan, valsartan) during acute CDI and withhold if appropriate due to acute kidney injuries. Remember to review ongoing need once infection has cleared. See AKI leaflet here.

    Review the lithium dosage during CDI (as diarrhoea can increase the lithium level) - obtain advice from the consultant psychiatrist, as appropriate.

    Replace fluid & electrolyte losses. Encourage eating and drinking.

    Assess nutritional risk & manage appropriately. Give all patients & carers patient information about C difficile infection via https://www.nhs.uk/conditions/c-difficile/

    Avoid prescribing cephalosporins, quinolones, clindamycin or co-amoxiclav / amoxicillin in future to patients who have had an episode of CDI.

    Discuss alternatives with a Consultant Microbiologist, if needed.

    Drug Treatment of mild-moderate CDI Where there is a strong clinical suspicion of CDI, start treatment: metronidazole 400mg three times a day for 10-14 days, as it has been shown to be as effective as oral vancomycin in mild to moderate CDI. Note. Patients with mild disease may not require specific C. difficile antibiotic treatment.2 Monitoring Regular assessment of the patient is essential to determine the severity of the infection, ensure effectiveness of treatment and early recognition of complications e.g. dehydration. Table 1: Assessment of severity of CDI

    Mild CDI Not associated with a raised WCC; it is typically associated with 50% increase above baseline) or a temperature of >38.5°C, or evidence of severe colitis (abdominal or radiological signs). Note. The number of stools may be a less reliable indicator of severity. A low serum albumin can be useful to detect profound protein loss / malnutrition in recurrent CDI or prolonged symptoms.

    Life-threatening CDI

    Includes hypotension, partial or complete ileus or toxic megacolon, or CT evidence of severe disease.

    Note. A conservative WCC threshold of 15 109/L has been chosen (to indicate severe CDI), as higher cut-off values may miss severe cases and relative immune paresis is common in the frail elderly who are most at risk of severe CDI. Elevated blood lactate >5 mmol/L is associated with extremely poor prognosis, even with colectomy.2

    Management in GP Practice – developed from national guidance On presentation / diagnosis (Day 1): Face to face assessment by clinician (ideally in patients home to minimise cross infection)

    determine severity of symptoms

    ensure carers/relatives/patient are able to cope at home with symptoms

    identify risk factors for complications/dehydration C. difficile infection is usually spread on the hands of healthcare staff and other people who come into contact with infected patients or with environmental surfaces (e.g. floors, bedpans, toilets) contaminated with the bacteria or its spores. Spores are produced when C. difficile bacteria encounter unfavourable conditions, such as being outside the body. They are very hardy and can survive on clothes and environmental surfaces for long periods (HPA).

    Record baseline observations i.e. temperature, pulse and blood pressure,

    Arrange Blood test for white cell count & serum creatinine.

    Provide Patient information and infection prevention and control advice.

    Severe disease and the potential need for hospital admission are indicated if any of the following parameters are met: (See Table 1 on page 5) o >38.5oC; o Evidence of severe colitis (abdominal or

    radiological signs); o BP 100bpm o WCC >15 109/L; o SCr >50% increase above baseline

    Provide Appendix 4 – This leaflet (for patients and carers) includes: The Bristol Stool Chart for monitoring type of bowel movements; information on hand washing, hygiene, cleaning; and patient information about C difficile and when to contact the GP / doctor. Provide Appendix 5 - IP&C information for Patients with C. difficile Infection in their own home / care home Appendix 4 & 5 adapted for use from Derbyshire Community Health Services NHS Trust, IPC team.

    Discuss ongoing monitoring with patient/carers to include keeping a daily diary recording frequency / type of bowel movements, deterioration in the patient’s condition or decrease in fluid intake. This monitoring could be completed by the carer/patient or by telephone with the GP.

    Signs of deterioration include: fever; abdominal distension or tenderness/pain; and increased diarrhoea. These should be reported to the GP as a formal medical review is needed. Please note that diarrhoea can reduce in severe CDI. Deterioration may be more likely in the frail elderly, in whom there should be a low threshold for formal review.

    Refer Where a patient shows signs of deterioration, or worsening disease is suspected, patients must be referred to hospital.

    Advise symptomatic patients to remain off work and minimise contact with others until the diarrhoea symptoms have ceased due to the risk of cross infection.

    Between days 4 and 6 of treatment An assessment of response to treatment should be made:

    Clinician to assess patient either by telephone or in person to ensure symptoms are resolving and patient is coping with the infection at home.

    If the symptoms are not reduced, the patient management should be discussed with the microbiologist

    Monitoring should continue as above until treatment course completed

    3 days after completion of treatment (or as soon afterwards as possible):

    A final assessment to be done by clinician to assess patient (either by telephone or face to face - as clinically appropriate) to ensure patient symptoms fully resolved and no other issues present

    Discuss with patient/carer actions to be taken should symptoms return Note: Further assessments may be needed, if clinically indicated by the patient's condition

    Referral Urgent admission is required when:

    A patient show signs of severe or life-threatening disease

    A patient show signs of deterioration or worsening disease is suspected. Tel. microbiologist for advice when: [01332 340131 or 01246 277271 ask for microbiologist on-call]

    A current (pre-disposing) antibiotic cannot be stopped.

    Oral route of administration is not possible / usual

    Symptoms are unresolved despite a 14 day course of treatment

    Second (subsequent) episode of infection occurs

    Antibiotic treatment is required for a patient with previous CDI [Broad spectrum antibiotics should be avoided in patients who have had a previous episode of CDI - see details above].

    Symptoms are not resolving & strong clinical suspicion of CDI remains despite negative stool sample (discuss further testing with microbiologist).

    Contact gastroenterologist for advice when: [via consultant connect/ email; or 01332 340131 or 01246 277271 ask for gastroenterology]

    Symptoms are not resolving and advised by microbiology to involve gastroenterology

    Stoma patients require management

    Diarrhoea persists despite 20 days of treatment, the patient is stable and frequency of stools (type 6-7) has decreased.

    Note. If WCC is normal and there is no abdominal pain or distension, the persistent diarrhoea may be due to post-infective irritable bowel syndrome.

    Re-starting anti-motility agents. These should NEVER be initiated by a GP. For any advice on infection prevention & control, see contact details on p3 summary. Recurrent infection Recurrence occurs in about 20% of patients, treated initially with either metronidazole or vancomycin. It is more common in elderly patients, with risk of further recurrence of nearly 50%. Any patients who recover and then relapse within 28 days should be treated as Clostridium difficile positive and the control measures re-introduced. Further samples should not be sent unless more than 28 days have passed. Treatment must be started promptly on clinical symptoms – do not lose time waiting for results. Note. A variable proportion of recurrences are reinfections due to a new strain (20-50%) as opposed to relapses due to the same strain; relapses tend to occur in the first two weeks after treatment cessation. After a first recurrence, the risk of another infection increases to 45–60%.2

    Treatment of mild, recurrent infections may be done in the community; patients with signs of moderate-severe disease should be referred for admission. If symptoms return after initial treatment (i.e. first recurrence), oral vancomycin (125mg 6 hourly for 10-14 days) is the recommended treatment2 The same management and monitoring should be performed (including reviewing and discontinuing any precipitating antibiotic, antimotility drugs, and anti-ulcer drugs where possible, etc.)

    For second and subsequent recurrences, contact microbiologist for advice on appropriate antibiotic treatment. The same management and monitoring should be performed as outlined above.

    Note. If a relapse of CDI occurs more than 28 days after the date of the specimen collection (for the first toxin positive result), then it is classed as a new case of infection. An episode of CDI is 28 days, with day 1 being the date of specimen collection.

    Obtaining Vancomycin If a patient has a prescription for vancomycin that pharmacy cannot obtain in a timely manner, patients could have their prescription dispensed at the pharmacy at local hospitals. UHDB: https://www.uhdb.nhs.uk/service-pharmacy Emergency situations only. There is a hospital pharmacist on duty 24 hours per day for 7 days per week, so this can be dealt with at any time. At weekends and evenings, please ask switchboard to bleep the on-call pharmacist. Chesterfield Royal Hospital: GP prescriptions (FP10) for vancomycin can be dispensed at the Pharmacy, Chesterfield Royal Hospital which is open on: Mon-Fri 8.30am-6pm; Sat 9am-1.30pm; Sun 10am-12 noon. This Pharmacy can also prepare an oral solution from Vancomycin injection (see Vancomycin injection Summary of Product Characteristics) if a patient is unable to swallow capsules. Fidaxomicin Fidaxomicin at dose 200mg twice daily for 10 days is the reserved treatment option on consultant microbiologist advice only (NICE/PHE Summary of antimicrobial prescribing guidance 2019). It is only used in severe CDI who have not responded to vancomycin or in patients with multiple comorbidities who are receiving concomitant antibiotics or for recurrence of CDI. Stock is not usually kept at community pharmacies although it may be obtained from wholesalers. To avoid delay in obtaining fidaxomicin follow same advice for obtaining vancomycin above.

    APPENDIX 2 Medicines that can produce diarrhoea1

    Diarrhoea is a common adverse drug reaction (ADR) with many medicines. Antimicrobials account for about 25% of drug-induced diarrhoea though most cases are benign.

    While diarrhoea has been seen with most medicines, the ones most commonly implicated are: • acarbose; • leflunomide; • antimicrobials; • magnesium preparations, eg antacids; • biguanides; • metoclopramide; • colchicine; • misoprostol; • cytotoxics; • NSAIDS, e.g. aspirin, ibuprofen; • dipyridamole; • olsalazine; • gold preparations; • orlistat; • iron preparations; • proton pump inhibitors; and • laxatives; • ticlopidine. Alternative diagnoses for the diarrhoea are important; therefore, careful attention should be paid to the temporal relationship between the time that the medicine is first taken and when the diarrhoea first appears.

    APPENDIX 3 Department of Health Mandatory 2 stage testing for Clostridium difficile Link to Department of Health information: http://www.dh.gov.uk/en/Publicationsandstatistics/Publications/PublicationsPolicyAndGuidance/DH_132927

    This method aims to provide more effective and consistent diagnosis across the NHS. The 2 stages include: Stage 1 – A test to detect the presence of C. difficile Stage 2 – a more specific test for detecting toxin A&B produced by C. difficile infection. Test information (see algorithm below for results explanation) C. difficile is an opportunistic anaerobic bacteria present in the intestines. It can produce toxins which results in infection. Some strains do not produce toxins but the bacteria being present can mean that the patient has the potential to excrete it and have an increased risk of developing the infection. This method will differentiate between patients who have active CDI and those that could be at risk of becoming infected (excretors). GDH: Glutamate dehydrogenase (GDH) is an enzyme produced in large amounts by both toxin and non-toxin producing C. difficile. Toxin A&B: C. difficile can produce 2 toxins A and B. They are responsible for causing infection. CDI: C. difficile infection Test ordering All electronic requestors will now see the test on ICM as: Faeces (C. difficile screen only) The test previously used: Faeces (Clost diff toxin only) will no longer be available Laboratory testing times Please ensure the sample arrives in the laboratory (Chesterfield or Derby):

    9:30am or 12:30pm Monday – Friday

    9am on Saturday and Sunday. If the sample arrives after this time it will be tested the next day. Note. Chesterfield Royal Hospital advise that if the test is needed to be done quickly, it may be possible to organise it with the laboratory and have the sample arrive by 2pm. It is recommended to keep faecal samples cool (4C).

    Algorithm - two stage C difficile testing & interpreting results on ICM:

    C. difficile GDH antigen test:

    Not detected DETECTED

    C. difficile Toxin A&B test

    ‘Clostridium difficile infection unlikely to be

    present’

    Not detected DETECTED

    ‘Clostridium difficile infection is likely to be present’ PPV= 91.4%

    ‘Potential Clostridium difficile excretor’

    Stage 1: All samples

    tested for GDH

    Stage 2: All GDH positive samples will be tested for toxin A&B

    This is NOT a C. difficile infection i.e. the patient is negative for infection but has the potential to become positive.

    However, if the patient has diarrhoea & there is a strong clinical suspicion of CDI, treatment MUST be initiated without waiting for a further stool sample result. Further advice can be obtained from microbiology. The clinical condition of the patient should always be considered.

    This is confirmation of C. difficile infection –

    treatment is needed

    C. difficile is very

    unlikely to be present

    How To Recognise Clostridium difficile Infection. Once normal stools have ressumed the infection has resolved, however medication prescribed for treatment of the infection must be completed. Some people may relapse up to a week after treatment and start with diarrhoea again. If this happens contact the doctor and discuss the need for more treatment. Keeping a diary of bowel movement will help the doctor to decide what treatment is needed.

    What is Clostridium difficile? It is a bacterium found in the large bowel that produces toxins which can irritate the lining of the bowel. What does it cause? The toxins can cause explosive and watery diarrhoea. Some people also experience nausea, stomach ache, fever and loss of appetite. Who is at risk of this infection? The people who are most at risk of getting clostridium difficile infections are the elderly who have recently been on antibiotics and have some other underlying illness or condition. Other people who may be at risk are those who have repeated hospital admissions, those whose immune system is affected by illness and/or treatment and those who have had recent surgery. How do I get it? 3% of the population have Clostridium difficile in their bowel. When these individuals are given certain antibiotics the normal bacteria in the gut are reduced and Clostridium difficile is able to reproduce more easily, producing more toxins. Sometimes the bacteria can be picked up on your hands from surfaces that have not been cleaned properly. How do we reduce the risk of germs spreading?

    You will need to take special care with hand washing. Wash hands in soap and water after using the toilet or bedpan and before eating

    It is also important that all carers and visitors wash their hands with soap and water when they visit or provide care for you.

    Carers should wear aprons and gloves when they come in to care for you or when they clean the toilet or bathroom areas.

    What else can be done to help? You need to ensure that you drink plenty of water to prevent dehydration from the diarrhoea. Ideally at least one drink after every episode of diarrhoea If you keep a diary of your bowel movements this will help carers and the doctor assess what treatment you need and when to stop your medication Your carers and the district nursing team will help you cope with the diarrhoea and ensure that the environment is kept clean. If you have any concerns please talk to your doctor or district nursing team When should I contact my GP? If your symptoms have not improved after 5 days of treatment, or you have stomach pain/swelling or high temperature (fever), or if you have any other concerns, contact your GP or doctor promptly.

    Can I give Clostridium difficile to my family and friends? Healthy people who are not taking antibiotics are at very low risk of getting this germ. Their best protection against even a small risk is to wash their hands after visiting you and follow the precautions as outlined above.
