• Abstract Aims 1. Compare the effectiveness of an automated disinfection system with hydrogen peroxide <8% and silver ion versus a manual method with 0.5% sodium hypochlorite solution to evaluate the reduction of microbial mesophilic contamination and Clostridium difficile (CD) presence; 2. Evaluate the organizational impact of these two technologies in terms of time required for the process. Methods A randomized multicenter trial performed in four public and private health facilities in the Emilia-Romagna Region, in different wards including medicine, orthopaedics, long-term care, recovery and functional rehabilitation, which were previously occupied by patients with Clostridium difficile Infection (CDI). When patients were discharged their rooms where randomized to 1 of 2 decontaminations arms. The surfaces where sampled using swabs, before and after disinfection. Swab samples were cultured for quantitative detection of microbial mesophilic contamination and qualitative detection of CD. Findings Before disinfection, 13% of surfaces decontaminated with hydrogen peroxide and silver ions and 20% surfaces decontaminated with sodium hypochlorite showed presence of CD spores. After disinfection, the samples containing CDs were 0% (p<0.001) in the group decontaminated with hydrogen peroxide and silver ions, while 3% (p<0.001) in the group decontaminated with hypochlorite sodium. The difference was not statistically significant (p=0.267). The difference in the reduction of the microbial mesophilic contamination was not statistically significant (p=0.193). Conclusions The differences between the groups were not statistically significant; however the disinfection with hydrogen peroxide and silver ions is preferable due to reduced dependence on operators.
