Between 15-25% of hospitalized patients have a urinary catheter placed during treatment, putting them at risk for a catheter-associated urinary tract infection (CAUTI) [2]. In fact, depending on location, patients can expect to have a catheter anywhere between 3-90% of their days at the hospital [3]. CAUTIs are one of the most common HAIs, with an estimated 93,000 occurrences in acute care settings and over 900,000 total across all hospitals and nursing homes. [1]. There are between 1.4 and 4.8 CAUTIs per 1,000 catheter days [3]. As much as 10% of the 215 million annual worldwide urological users have reported CAUTIs [4] [5]. Developing countries have infection rates often as high as 5 times higher than developed countries. Unlike other HAIs, CAUTI rates have not declined since 2008, making innovations that can decrease that rate particularly attractive [6]. 

The population at risk for CAUTIs is the largest at risk of any HAI (Table 2. [7]). CAUTIs result from bacteria colonizing catheters while they reside in the body, eventually infecting the bladder, kidneys, or bloodstream. The catheters and collection bags can contain large numbers of undetected drug-resistant microorganisms in close proximity to the patient, acting as reservoirs for pathogens that can result in more serious and costly HAIs [8]. Current externally applied pharmacologic disinfection through introduction of antibiotics or antiseptics has very poor clinical efficacy. This is in part due to biofilm formation and antibiotic resistant strains of bacteria. Because this problem remains unsolved with current products, infection rates and associated healthcare costs continue to rise. Though antibiotic-resistant strains of bacteria become more common each year, the pace of approval of new antibiotics has dramatically slowed. The problem of drug resistant infections will continue to grow and is best addressed with a solution that is independent of microbial antibiotic resistance mechanisms.
