Abstract:ObjectiveTo analyze the application efficacy of acidic electrolyzed oxidizing water (AEOW) in healthcare associated infection(HAI) control in mobile field hospital.MethodsHand hygiene, environmental object surface disinfection, medical instrument cleaning were performed with AEOW as well as different commonly used cleaning and disinfectant agents in mobile field hospital, ATP biological fluorescence detector was used to detect and evaluate the efficacy of cleaning and disinfection.ResultsThe qualified rates of hand washing with running water as well as soap and AEOW were 100.00% and 98.75% respectively, there was no significant difference between two groups (P=1.000). Environmental object surface were disinfected with AEOW, chlorine containing disinfectant, and compound double chain quaternary ammonium salt wipe, the qualified rates were 87.10%, 90.32%, and 90.32% respectively, there was no significant difference in the qualified rates among three methods (P=1.000). The qualified rates of instruments cleaned by AEOW and conventional cleaning were both 100%. The mean value, standard deviation, and standard error of mean value of relative light unit (RLU) of instrument specimens after cleaned by AEOW were all 0, after cleaned by conventional method were 9.70, 8.91, and 1.63 respectively，difference in RLU after cleaned by two methods was statistically significant (t=-5.97, P=0.000).ConclusionCompared with other commonly used disinfectants, AEOW can achieve the desired results in hand washing, object surface disinfection, as well as instrument cleaning. In view of its onsite preparation and convenient use, it shows a effectiveness, compatibility, and superiority in HAI control in mobile field hospital.
