不同专科重症监护病房高频接触物体表面的量性研究

Quantitative study on hightouched object surface in different special intensive care units

摘要:

目的通过对不同专科重症监护病房（ICU）常见物体表面接触次数进行观察统计，明确不同专科ICU的高频接触物体表面，为医院环境管理提供依据。方法采用直接观察法对医务人员的日常活动进行观察，记录各类常见物体表面的接触次数，采用Poisson分布对数据进行统计分析。结果ICU的高频接触物体表面日平均接触次数由高至低依次为病历夹（28.00次）、椅子（18.38次）、抢救车（治疗车，17.29次）、床表面（13.90次）、静脉输液管路（13.76次）、医护用笔（13.38次）和静脉输液泵（11.81次）。这7类物体表面在观察期间的接触次数占所有物体表面接触次数的64.01%。不同专科ICU又略有差异：综合ICU的高频接触物体表面是上述的前6类；心胸外科ICU的高频接触物体表面除了包含上述的7类外还包括键盘与鼠标，共9类；内科ICU的高频接触物体表面是上述前6类及手机。结论同一所医院不同专科ICU高频接触物体表面不同，因此医院应根据各科室高频接触物体表面的实际情况制定相应的消毒管理措施，继而减少医院感染的发生。

Abstract:

ObjectiveTo identify the hightouched 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 hightouch 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. ConclusionHightouched 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 hightouched surface of each department, so as to reduce the incidence of healthcareassociated infection.
