AB  - BACKGROUND: Clostridium difficile is a major nosocomial pathogen causing mild 
      diarrhoea to life-threatening pseudomembranous colitis, and its spores frequently 
      contaminate hospital environments and equipment. Washer/Disinfectors (WDs) are 
      commonly used to clean and decontaminate soiled equipment in health care 
      facilities. This study aimed to evaluate the effectiveness of the DEKO-190 WD in 
      removing C. difficile spores from bedpans. METHODS: Plastic carriers were 
      inoculated with suspensions of C. difficile spores in autoclaved (sterile) human 
      faeces. The carriers were then taped to a sterile plastic bedpan which was 
      subjected to short, long or intensive wash cycles in the WD using one of two test 
      detergents: Formula A (generic) and Formula B (highly alkaline). Mean log(10) 
      reductions in spores were calculated for each wash cycle. RESULTS: Mean log(10) 
      reductions were 3.21(SEM +/- 0.20) and 2.82 (+/-0.13) for Formula A and B, 
      respectively, for the short cycle. The mean log(10) reductions using the long 
      wash cycle were 3.65 (+/-0.44) using Formula A and 5.30 (+/-0.43) using Formula B, 
      while log(10) reductions were 3.37 (+/-0.58) (Formula A) and 4.64 (+/-0.47) (Formula 
      B) for the intensive cycle. Washing with the DEKO-190 significantly reduced spore 
      concentrations on carrier surfaces on a bedpan. Spore counts were most 
      effectively reduced when carriers were washed on a long or intensive wash cycle 
      using an alkaline detergent.
