Catheter Associated Urinary Tract Infection (CAUTI)

Clinical Considerations

  • Patients with urinary catheters develop bacteriuria at a rate of 3-7% per day

  • At 30 days, all urinary catheters are colonized with bacteria

  • High rates of bacterial colonization and non-specific signs of infection (such as cognitive or functional changes) make differentiating between asymptomatic bacteriuria and CAUTI challenging

Elimination of unnecessary catheters is the best way to prevent CAUTI
