Putting disinfection devices onto the siphons of sinks can help manage multidrug-resistant Pseudomonas aeruginosa colonization in intensive care units, according to a study published in Journal of Hospital Infection. Researchers examined the efficacy of placing devices on sink siphons that apply heat and electromechanical vibration to disinfect the draining fluid. In April 2013, these devices were installed on sinks in a sub-unit of a hospital’s ICU, called ICU A in the study. In another sub-unit, ICU B, they replaced sink siphons with polyvinyl chloride plastic siphons. The baseline P. aeruginosa colonization rate of sinks was 51 percent in ICU A and 46 percent in ICU B.
