Background and aim: Disinfection is a process in which pathogenic microorganisms of Abiotic surfaces are disappeared.
Choosing a suitable disinfectant and using standard methods of disinfection can be effective in reducing nosocomial infections. This
study aims to compare the effectiveness of newly market disinfectants with commonly used disinfectants in Iran in reducing hospital
infections index: Case study of Kermanshah hospitals.
Materials and methods: In this descriptive analytical study, a total of 450 microbial samples were randomly taken from different
parts of Kermanshah hospitals. In microbiology lab of Kermanshah University of Medical Sciences, all the samples were cultured
on blood agar medium and the specific culture medium for each bacteria was used. In this study, three new disinfectants supplied
to the market including Sayaspt HI, Turbo septi, 50 Deconex AF were compared with commonly-used disinfectants including
Sayasept HP, Deconex 53 plus and DeconexSolarsept.Data were analyzed using one-way ANOVA, independent two-group T-test and
Results: In examining the effectiveness of new and current disinfectants in surveyed hospitals, it was observed that the average
of overall performance of common disinfectants was 96.7 % and the average of overall performance of new disinfectants was 98.5 %
in reducing the indicators of hospital infections. Among large surface disinfection Deconex 50 AF had the highest performance in
reducing nosocomial infection; and among small surfaces disinfection septi Turbo had the highest performance in reducing nosocomial
infection. Also among equipment and materials disinfection Sayasept HI had the highest performance in reducing nosocomial
Conclusion: According to the results, to disinfect tools and equipment Sayasept HI is proposed. To disinfect large surfaces 50
Deconex AF is recommended and to disinfect small surfaces DeconexSolarsept is suggested.
