Catheter-Associated Urinary Tract Infection

General Principles

  • Catheter-associated urinary tract infection (CAUTI) is the most common HAI.
  • E. coli, other gram-negative Enterobacterales, P. aeruginosa, gram-positives (staphylococci, enterococci), and yeast are commonly isolated from catheterized urine.
  • Aseptic technique during insertion of a catheter is of utmost importance for prevention of CAUTI as well as prompt removal of the catheter when no longer needed.
