Using Root Cause Analysis to
tackle C difficile infections….

Local population of around 280,000
- 25% over 65 (national average 19%)
Torbay District General hospital

450 beds (around 15% side rooms; ≈$150M backlog maintenance)
In top 3 nationally for day case rates
Average length of stay 3.6 days (down from 4.7 in 2004)
Bed occupancy >85%

How did we improve?
Root Cause Analysis
Environmental cleaning
routine use of hypochlorite;
greater frequency;
dedicated cloths per bed space
Antibiotic prescribing
better guidelines;
frequent audit and feedback;
more education for junior docs
Hand hygiene

Root cause analysis
Started for hospital acquired cases in autumn 2007
Investigational team must include;
a medical rep (consultant or junior doctor)
a nursing rep
an infection control rep
- plus others as appropriate
Aimed to be as flexible as possible during RCA
no blame
establish timeline:
• “what do you want to celebrate and share?”
• “what do you wish had never happened – and
how would you avoid it next time around?”
Root cause analysis
Early learning
- often a multitude of things going wrong
- ‘shame / embarrassment‘ is a powerful driver for
change!
- talking about problems / sharing learning at clinical
meetings → getting C difficile on clinical agenda
Principal benefits
More understanding about risk (“trigger questions”)
C difficile is not an inevitable part of modern
healthcare – it is an avoidable event
Root cause analysis – clean safe care

2008 - tried the new tool
• stifled discussion
}
• medics switched off
• ‘closed’ analysis
Very detailed / data driven (eg policy
revision dates & compliance audits)
-> formalise our processes
• lay out RCA process
• make local ownership more consistent
• work up full list of trigger questions
• incorporate ‘good bits’ into local tool
• better control of action plans

Speed is key……
• How quickly was diarrhoea flagged up?
• How quickly was the patient isolated?
• How quickly was the area cleaned?
• How quickly was the sample collected?
• How quickly was empirical treatment started?
• How quickly were other treatments reviewed?
• How quickly did the lab report the result?
• How quickly was a positive test responded to?
• How quickly was any failure to improve reacted to?
Root cause analysis – selected trigger questions (1)
• Was D&V assessment undertaken and documented within
the medical notes on admission?
• Has the patient had C difficile within the last 12 months?
Was this reflected in the medical notes?
• Was the patient weighed on admission? Evidence of
malnutrition?
• If the patient started antibiotics, was this in keeping with
trust guidelines? Did the potential benefit of antibiotic
treatment outweigh the potential risks?
Root cause analysis – selected trigger questions (2)
• When did the patient commence with diarrhoea and was
it documented in the medical records?
• Is there an assessment of diarrhoea severity in the
medical notes (e.g. frequency, stool consistency, systemic
upset including WCC, CRP etc)?
• Was empirical treatment for C difficile given?
• If not already happened, following the positive lab report,
how quickly was C difficile treatment commenced?
• How were other clinical teams on the ward made aware
of this new diagnosis?
Root cause analysis – selected trigger questions (3)
• Was the side room cleaned twice daily with hypochlorite
solution and was this recorded?
• What method of hand hygiene was promoted? How?
• Were doses of treatment ever missed, eg through patient
refusal or medical condition? Is this reflected in the medical
notes?
South Devon Healthcare NHS Foundation Trust
Internal target of zero clusters of C difficile
National target in 2009/10 of <= 70 cases
Actual number 27 cases (8 possible clusters - doubtful)
→ better care for patients; better life for staff
In nearly half of all months, we only have one hospital
acquired C difficile case
→ everything
becomes more manageable
