The coating was applied to four orthopedic wards in a local hospital in Hong Kong. Two wards acted as the control group and two wards acted as the treatment group. The two groups were swapped after 6 months of experiment. For the treatment group, bed-rail, chest table and locker were coated by wiping with the coating in addition to the daily cleaning with bleach (1000 ppm). For the control group, bleach (1000 ppm) was used to clean the surface daily. Environmental swabs (N= 2249) were taken from the patient immediate environment twice a month. Our study showed that there was an overall 0.369 log10 reduction of biological contamination on the surface involved in this study compared to the normal cleaning regime.
The result has indicated the feasibility of an improved cleaning regime. The add-on effect of antimicrobial activity towards existing furniture is a workable solution for reducing nosocomial infection.
