Disinfection devices in ICU sinks can help manage Pseudomonas aeruginosa colonization, according to an article on the Becker's Clinical Leadership and Infection Control website.
In a study published in Journal of Hospital Infection, researchers placed devices on sink siphons that applied heat and electromechanical vibration to disinfect the draining fluid.
They found that after the devices were installed, colonization decreased to 5 percent. The colonization rate increased to 62 percent in sinks with plastic siphons.
Multidrug-resistant P. aeruginosa colonization in ICU patients decreased from 8.3 per 1,000 admitted patients to 0 per 1,000 admitted patients with the devices.
