Catheter-associated urinary tract infections (CAUTIs) have become a target for systematic reduction efforts because of the fact they are the most common hospital-acquired infection (HAI), and they lead to excess cost, length of stay, and patient morbidity. Evidence-based interventions exist to reduce these infections,1, 2, 3 and 4 and the Centers for Medicare and Medicaid Services will no longer pay for the costs incurred by the rising case complexity because of hospital-acquired CAUTIs.5 Although public reporting of such infections is not yet common, and the National Healthcare Safety Network (NHSN) has limited its reporting to only symptomatic infections, the total impact of catheter-associated bacteriuria (symptomatic and asymptomatic) is high. At Stamford Hospital, from 2000 to 2008, catheter-associated bacteriuria was the most common HAI, representing 28.2% of all HAI cases. Although some episodes of bacteriuria will resolve spontaneously when the catheter is removed, 40% to 60% of asymptomatic catheter-associated bacteriuria will persist6 and 7 and require medical follow-up and/or specific intervention for symptoms.
