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
