某儿童医院病床隔帘污染情况调查与分析

Investigation and Analysis of the Contamination Status of Bed Curtains in a Children's Hospital

目的:了解某儿童医院病床隔帘清洗后使用不同时间的污染情况,为制定隔帘清洗频率提供依据。方法:采用分层随机抽样法随机抽取急诊科及普通病区7个科室的隔帘标本,分别于清洗后立即、使用1周、使用1~5个月分7次对隔帘进行采样,并记录菌落数。结果:隔帘清洗后使用不同时间、不同科室、不同病区的污染率差异均有统计学意义(P<0.05),普通病区的隔帘污染率显著高于急诊科;内科隔帘的菌落数最多,急诊科最少。结论:清洗后的病床隔帘在使用1周后就有不同程度的污染,使用时间越长,污染越严重,应根据污染情况对隔帘定期清洗,对于污染较为严重的科室应增加隔帘清洗频次。

Objective:To understand the contamination status of bed curtains in a children's hospital after washing and at different times of use,and to provide a basis for establishing the frequency of curtain washing.Methods:A stratified random sampling method was used to randomly select curtain samples from seven departments in the emergency department and general wards.Sampling was carried out seven times,that was,immediately after washing,one week after use,and once per month from 1 month to 5 months after use.The numbers of colonies were recorded.Results:There were statistically significant differences in contamination rates of curtains among those used for different durations of usage,in different departments,and in different wards(P<0.05).The contamination rate in general wards was significantly higher than that in the emergency department.The number of colonies on the curtains in the internal medicine department was the largest,and that in the emergency department was the smallest.Conclusion:The washed bed curtains will be contaminated to varying degrees after one week of use,and the longer they are used,the more serious the contamination is.It is necessary to regularly wash the curtains according to the contamination status,and increase the frequency of curtain washing for departments with more severe contamination.
