Assays

Identify, control, and prevent the spread of CPO

  • The European CDC states that pathogens resistant to carbapenems are one of the biggest threats to patient safety1
  • A large proportion of carbapenem-resistant Enterobacteriaceae (CRE) infections currently lack effective and relatively safe antibiotic treatment options2
  • CRE patients are 3 times more likely to receive inappropriate empiric therapy than non-CRE patients (46.5% vs 11.8%) resulting in longer hospital stays and increased system cost3
  • Carbapenemase genes KPC and OXA-48 were found most frequently in carbapenemase resistant Klebsiella pneumoniae and Escherichia coli4

Screening for colonisation is a key component of CPO control5

Active surveillance can reduce transmission of CPO in healthcare settings6,7

Screening hospital inpatients for CPO can be cost-effective and even cost-saving7

Hospitals in the Netherlands and UK have estimated the economic impact of an out-break in their facilities to be approximately €1,000,0008,9
The European Centre for Disease Prevention and Control recommends investing while prevalence is low, as once an endemic situation is reached, it is more costly and less effective10

The BD MAXTM Cdiff assay provides rapid detection of the C. difficile toxin B gene (tcdB),
the gene essential for CDI1, including infections caused by hypervirulent strains

  • CDI is the most important (preventable) infective cause of healthcare-associated diarrhoea in Europe and is associated with high morbidity and mortality2
  • The BD MAX™ Cdiff assay is a real time polymerase chain reaction (PCR) assay offering diagnostic speed and accuracy to allow fast treatment decisions and prevent transmission of infection3
  • Traditional diagnostic methods can be time-consuming (toxigenic culture or cell cytotoxicity neutralization assay) or may have poor sensitivity (glutamate dehydrogenase assays)4-5
  • PCR is recommended by ESCMID guidelines as a primary test in a 2-step algorithm for diagnosis of CDI2
  • The BD MAX™ Cdiff assay is integrated on the fully automated BD MAX™ System and is run compatible with
    other healthcare associated infection (HAI) assays3
  • Results are available in approximately 2 hours with only 1 minute of hands-on time per specimen3
