|Healthcare Hygiene Magazine recently spoke with William A. Rutala, PhD, MPH, CIC, the associate chief medical officer for the UNC Medical Center; medical director of the Departments of Hospital Epidemiology and Occupational Health Service; and director of the North Carolina Statewide Infection Control Program (SPICE), about the role that automated room disinfection technology plays in environmental hygiene.
In the interview, Dr. Rutala stressed the important role that manual cleaning remains to play as well as how “no-touch” disinfection technologies can complement existing cleaning protocols.
“There are at least six clinical trials that demonstrate a reduction of HAIs with the use of hydrogen peroxide systems and seven that demonstrate a reduction in HAIs with UVC,” Rutala said. “One study showed enhanced room decontamination strategies (i.e., bleach and/or UVC decontamination) decreased the clinical incidence of acquisition of target multidrug resistant organisms (i.e., MRSA, VRE, C. difficile by -10 to 30% (p=0.036). Comparing the best strategy with the worst strategy (i.e., quat vs quat/UV) revealed that a reduction of 94% in epidemiologically important pathogens (i.e., 60.8 CFU per room vs 3.4 CFU per room) led to a 35% decrease in colonization/infection (2.3% vs 1.5%).”
