Aims and objectives To enable you to:
Be aware what Clostridium Difficile is
Be aware of who is at risk
What the risk factors are
How to reduce risks
How to recognise and respond
How to minimise risks
Be aware of the importance of infection control

What is Clostridium Difficile? Gram positive spore
forming anaerobic bacteria.
Lives in soil Discovered 1935 in
faeces of newborns Became a problem when
broad spectrum antibiotics introduced late 1960s early 1970s
![Page 4: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/4.jpg)
Clostridium Difficile Older person 10 times more likely to be
killed by C.Diff than a car 50,392 ,older people infected in 2007 In 2004 934 deaths – mostly older
people Death rate doubled 2007/2008 In 2008 8,324 deaths Killed four times as many as MRSA

Risk factorsAge – over 65
Current or recent antibiotic therapy
Poor physical health
Admission to intensive care unit
Recent surgery
Use of antacids or drugs such as ranitidine or omeprazole (these reduce stomach acidity and increase the risk of infection.
Nasogastric or gastrostomy tube in place
Prolonged hospital stay
Use of enemas
Pre-existing bowel disease
Sharing a room with some one with C. difficile

Reducing risk factors Proton pump inhibitors (PPIs) such as
omeprazole or lansoprazole increase risk of developing C. Difficile.
They reduce the acidity in the stomach and small bowel and affect the natural bowel flora in the large bowel (Cunningham et al. 2003: Chitnis et al, 2013).
Ensure PPIs are clinically indicated Review “orphan” medication
![Page 8: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/8.jpg)
Reducing risk factors Prudent antimicrobial prescribing, 50%
Px unecessary Use narrow spectrum not wide (co-
amoxiclav,cephalosporins and quinolones). GP practices monitored only max 10% incentives for meeting targets (NHS England, 2016).
Avoid high risk ABX whenever possible
![Page 9: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/9.jpg)
Reducing risk factors Reduce use invasive medical devices In NHS hospitals 1 million catheterised every
year Reduce use IV cannula When med device isn’t needed take it out Avoid discharge delays Avoid over-occupancy 85% regarded as
safest

Stop Any medication that is making the
diarrhoea worse. Discontinue laxatives Any prescribed proton pump inhibition
(PPI) that can be safety discontinued. Any antibiotics that can be
discontinued In mild cases of C. difficile antibiotic
treatment may not be required.
![Page 13: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/13.jpg)
C. Difficile treatment recommendations(Public Health England, 2013)
Level of severity
Treatment
Mild Patients with mild disease may not require specific C. difficile antibiotic treatment. If treatment is required, oral metronidazole 400=500mg three times a day for 10-14 days is recommended
Moderate Patients with moderate disease should be treated with oral metronidazole 400-500mg three times a day for 10-14 days. Oral vancomycin is not recommended as may lead to the development of further antibiotic resistance
Severe For patients with severe disease should be treated with oral vancomycin (dose: 125 mg four times daily for 10-14 days. Fidaxomicin should be considered for patients with severe disease who are considered at high risk for recurrence, such as older people who need to have other antibiotics and have multiple long term conditions.

Isolate
C. Difficile is spread; by faecal/oral transmission and by spores.
Faecal oral transmission occurs when bacteria from faeces passes into the mouth of another person. Poor hand washing
Contaminated healthcare environment toilet seats, commodes, bedpans, bedside lockers, beds and floors.
![Page 15: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/15.jpg)

Monitor patient Age and general health affect condition acutely unwell or simply have mild symptoms. Monitor carefully and be alert to any deterioration. Fluid intake and output recorded on a fluid balance chart. Stool frequency, volume and consistency will be
monitored. Maintain observations of temperature, pulse, blood
pressure, respirations and oxygen saturations. Diarrhoea increases the risk of skin becoming sore and
excoriated and skin health should be monitored.
![Page 17: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/17.jpg)
Support The person may be weak and unwell. Assist with hygiene and continence Encourage oral fluids Monitor any prescribed IV fluids Treat pain Skin care, barrier creams Combating isolation and offering
supportive care
![Page 18: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/18.jpg)
Clinical features C. difficile Cramping abdominal pain, tenderness in the
lower abdomen Pyrexia Mild to moderate watery diarrhorrea Feeling unwell Loss of appetite Dehydration Dry mouth Tachycardia
![Page 19: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/19.jpg)
Importance prompt treatment
8,324 reasons why we need to treat promptly Toxins released by C. diff set up inflammation Life threatening complications such as colitis,
oedema of bowel, bowel perforation, pseudomembranous colitis can develop.
![Page 20: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/20.jpg)

Diagnosis and treatment Diagnosed by clinical features and stool
sample Treatment may begin before results of
specimen available Stop antibiotics if possible Antibiotic therapy may be needed Normal therapy metronidazole or
vancomycin
![Page 22: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/22.jpg)
Preventing cross infection Spread by spores. Can live on floors, toilet seats, furniture,
equipment for months. Common cleaning agents can spread spores Alcohol gels ineffective Hand washing removes Killed by sodium hypochlorite (bleach) Separate toilet, commode, bedpan for person
with C. Diff.
![Page 23: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/23.jpg)
Preventing C. Difficile Prudent antibiotic use Avoiding cephalosporins and broad
spectrum antibiotics whenever possible Strict hand hygiene Correct cleaning & use chlorine based
disinfectants when C. Difficile occurs Early detection and treatment
![Page 24: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/24.jpg)
Outbreak management Emphasise importance hand washing – alcogels
useless Isolate if not possible cohort nurse Barrier nurse Get more staff, especially domestics! Step up cleaning “using chlorine based disinfectants” Stop visiting –limits infection, reduces pressures Stop admissions – 48 hours after last symptoms Stop outpatient visits
![Page 25: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/25.jpg)
Managing outbreak well Outbreak can happen to the best of us Be open, honest and decent Work with others, if patients are
admitted to another hospital communicate with hospital staff
Communicate with relatives, face to face, email, letters
Take time with people and reassure
![Page 26: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/26.jpg)
Gaps in infection control Poor compliance with hand
washing “Magic” gloves Poor cleaning Poor food handling Sick staff coming to work Lack of isolation and risk
assessment Lack of gloves, aprons,
alcohol gel, bleach in some healthcare settings.
![Page 27: LSBU C Diff 2016](https://reader034.vdocuments.us/reader034/viewer/2022051507/58a911cc1a28ab6d2d8b58cf/html5/thumbnails/27.jpg)
Demystifying infection control
Infection control is simple: Wash your hands Keep things clean Use gloves and aprons when needed Avoid unnecessary antibiotics Keep people well by giving good care
