Diagnosis, management, and prevention of catheter-associated urinary tract infections.

Catheter-associated urinary tract infection (CAUTI) is common, costly, and causes significant patient morbidity. CAUTIs are associated with hospital pathogens with a high propensity toward antimicrobial resistance. Treatment of asymptomatic patients with CAUTI accounts for excess antimicrobial use in hospitals and should be avoided. Duration of urinary catheterization is the predominant risk for CAUTI; preventive measures directed at limiting placement and early removal of urinary catheters have an impact on decreasing CAUTI rates. The use of bladder bundles and collaboratives, coupled with the support and active engagement from both hospital leaders and followers, seem to help prevent this common problem.
