C Difficile - The Ultimate Challenge: Controlling the Spread
The Big Picture C difficile lab ID reported through NHSN Proposed for Value Based Purchasing FY 2017

C difficile Now rivals MRSA as the most common organism found in
hospitals Incidence outside the hospital may be more common
than previously thought Associated with increased length of stay, morbidity and
mortality
Impact of C. difficile infection (CDI)
Hospital-acquired, hospital-onset: 165,000 cases, $1.3 billion in excess costs, and 9,000 deaths annually
Hospital-acquired, post-discharge
(up to 4 weeks): 50,000 cases, $0.3 billion in excess costs, and 3,000 deaths annually
Nursing home-onset: 263,000
cases, $2.2 billion in excess costs, and 16,500 deaths annually

Pathogenesis Alteration of the intestinal flora by antibiotics leads to C. difficile proliferation in the colon
C. difficile is acquired by ingestion of spores from the hospital environment or hands of healthcare personnel
C. difficile diarrhea
Advanced age Multiple comorbidies No antibody to Toxin A/B
No diarrhea
Antibody to Toxin A/B
Colonization
Ingested Normal flora interrupted
Small Intestine Spores Germinate
Pseudomembrane C Difficile
toxins
monocytes
Neutrophils
Toxin A attracts neutrophils and monocytes, and toxin B degrades the colonic epithelial cells, both leading to colitis, pseudomembrane formation, and watery diarrhea
C difficile reproduces in the intestinal crypts, releasing toxins A and B, causing severe inflammation. Mucous and cellular debrisare expelled, leading to the formation of pseudomembranes

Pseudomembrenous Colitis
“I just touched the bed rail…” 100-1,000 bacteria transferred by: Pulling patients up in
bed Taking a blood
pressure or pulse Touching a patient’s
hand Rolling patients over
in bed

C Difficile in the enviornment C. difficile forms an endospore or a dormant state with
increased resistance when conditions in the human or animal body or the environment become unfavorable for it to survive in its vegetative (actively growing) state.
In the endospore stage, C. difficile spores will not be destroyed on environmental surfaces by disinfectants
Transmission- Fecal – Oral Route
o Mainly by direct contact with the hands of HCWs
o Autoinoculation (oral ingestion) o Shed in feces o Indirect contact (inanimate objects such as
commodes, etc) o Environmental contamination – spores can
survive for months in the environment
What’s Wrong With This Picture
Another One
What are the symptoms of Cdiff? watery diarrhea fever loss of appetite nausea abdominal pain/tenderness
(Be wary of lack of stools)
CDI Prevention Strategies: Core Contact Precautions for duration of diarrhea Hand hygiene in compliance with CDC/WHO Cleaning and disinfection of equipment and
environment Laboratory-based alert system for immediate
notification of positive test results Educate about CDI: HCP, housekeeping,
administration, patients, families http://www.cdc.gov/ncidod/dhqp/id_CdiffFAQ_HCP.html

The Compendium
Outbreak or Hyper-endemic Setting only
Hyper-endemic levels
Other Issues Lab ID is a marker. May also pick up colonization
What are your criteria for sending a specimen
Any Inappropriate testing?
Testing methods PCR 2 STEP Toxin- A and B antigen
Renewed Respect for Role of the Environment: Who’s Been in the Room Before or With You?
Huang SS (2006); Drees M (2008); Zhou Q (2008); Moore C (2008);Hamel M (2010) All documented increased risk of
acquisition of VRE, MRSA, &/or CDI when admitted to room where prior occupant had one of these or if in multi-occupancy room
So what’s the answer?
No Doesn’t
