Executive summary

Key facts:

  • In 2017, 8.3% (11 787) of the patients who stayed in intensive-care units (ICUs) for more than two days presented with at least one ICU-acquired healthcare-associated infection (HAI) under surveillance (pneumonia, bloodstream infection, or urinary tract infection).
  • Of all patients staying in an ICU for more than two days, 6% presented with pneumonia, 4% with bloodstream infection (BSI), and 2% with urinary tract infection (UTI).
  • Ninety-seven per cent of pneumonia episodes were associated with intubation, 37% of BSI episodes were catheter-related, and 98% of UTI episodes were associated with presence of a urinary catheter.
  • The most frequently isolated microorganism was Pseudomonas aeruginosa in ICU-acquired pneumonia episodes, coagulase-negative staphylococci in ICU-acquired BSIs, and Esc herichia coli in ICU-acquired UTIs.
  • Twenty-four per cent of Staphylococcus aureus isolates were oxacillin-resistant (MRSA) and 10% of Enterococcus spp. were glycopeptide resistant. Resistance to third-generation cephalosporins was reported in 16% of E. coli isolates, 40% of Klebsiella spp. isolates and 34% of Enterobacter spp. isolates. Carbapenem resistance was reported in 15% of Klebsiella spp. isolates, 26% of P. aeruginosa isolates and 64% of Acinetobacter baumannii isolates.
