Catheter Associated Urinary Tract Infection (CAUTI) is defined as the occurrence of a urinary tract infection (UTI) in patients with a urinary catheter in the past 48 hours. Published guidelines by the Infectious Diseases Society of America (IDSA) further defines CAUTI by the presence of significant bacteriuria of ≥ 103 CFU/ml found in the urinalysis and signs and symptoms of a UTI without the presence of another cause for these findings. Signs and symptoms of CAUTI could include: altered mental status, fever, chills, flank pain, costovertebral angle tenderness, and hematuria. If the catheter has been removed in the past 48 hours the symptoms could also include urgency and frequency (Fakih et al., 2016).
A2. Significance of the problem
The most common health care associated infection (HAI) is CAUTI. Forty percent of all hospital-acquired infections are UTIs and 80% of these are directly linked to having an indwelling urinary catheter in place (Underwood, 2015). Urinary catheters are required in up to 25% of hospitalized patients and bacteriuria results in about 25% of patients with a catheter for greater than 5 days and this number increases by 1 to 5% for each day the catheter is in place after that. The harmful consequences of CAUTI include increased length of stay, higher health care cost, and increased mortality. CAUTI is known to cost health care in the U.S. $400-$500 million annually (Leuck et al., 2015).
