Abstract:ObjectiveTo identify the hightouched object surface in different special intensive care units(ICUs) through the observation and statistical analysis on the number of touching with common object surfaces in different ICUs, so as to provide basis for hospital environmental management. MethodsDirect observation method was used to observe the daily activities of health care workers, the number of touching with various common object surfaces was recorded, Poisson distribution was adopted to statistically analyze the data. ResultsThe average number of touching from high to low was as follows : medical record folder（n=28.00）, chair（n=18.38）, emergency rescue cart（treatment cart, n=17.29）, bed surface（n=13.90）, intravenous infusion line（n=13.76）, medical pen（n=13.38）, and intravenous transfusion pump（n=11.81）, these objects accounted for 64.01% of all surface touching number. Different special ICUs were slightly different, general ICU hightouch object included the first 6 categories; cardiothoracic surgery ICU included the above 7 categories besides keyboard and mouse; internal medicine ICU included the first 6 categories and mobile phone. ConclusionHightouched object surface varied with different special ICUs of the same hospital, hospital should make the corresponding disinfection management measures according to the actual situation of hightouched surface of each department, so as to reduce the incidence of healthcareassociated infection.
