At least 29 studies incriminate the hospital water system as the source of serious waterborne hospitalacquired infections.1 Patient exposure occurs while showering, bathing and drinking. Reports recommend minimizing exposure to tap water for all patients who are immunocompromised, have fresh surgical wounds, or are at higher risk for infections.1,2 Another study finds biofilm-forming pathogens can create potent biofilms in hospital pipes, hot water tanks, sinks and even touchless faucets, contaminating water on contact.3
Patient bath water is a proven, significant source of high-level bacteria contamination. In fact, the high bacteria count in bath water is similar to the number in urine from patients with UTIs.4 Other basin uses, including emesis and incontinence cleanup, increase the risk. Nurses frequently make contact with equipment, including sink handles, where contaminated water is disposed. This can expose everyone in the room to potential contamination.
