摘　　要：目的了解上海市某医院病床隔帘表面细菌污染状况,并提出相应的管理措施,为医院病床隔帘的更换清洗频率提供科学依据。方法按标准方法连续采集该院2018年7-12月呼吸科、感染性疾病科、胸外科、外科、ICU 5个科室内的病床隔帘在清洗后使用的即时(0 d)、1周、2周、3周、1个月、1.5个月、2个月、3个月、4个月、5个月的样本,ICU在使用第1周内的第2天和第4天增加了检测频次。总共收集312份标本,对病床隔帘细菌菌落总数进行监测和分析。结果更换隔帘后不同时间段病床隔帘染菌量差异有统计学意义,大部分科室在1.5个月时细菌菌落总数的中位数达到峰值;各科室病床隔帘细菌菌落总数超标率差异有统计学意义(χ2=17.726,P=0.001),其中感染性疾病科超标率为31.67%,呼吸科为30.00%,略高于外科(28.33%)和胸外科(28.33%),而ICU的超标率最低,仅为5.56%;内、外科病房病床隔帘细菌菌落总数的差异较小(P>0.05),普通病房与ICU病床隔帘细菌菌落总数的整体分布位置不同,且ICU的病床隔帘细菌菌落总数小于普通病房(P<0.05)。结论研究显示医院病床隔帘的污染程度与不同科室环境有关,病床隔帘的更换频率应根据医院不同科室的情况进行合理调整,以减少医院感染。Objective To understand the status of bacterial contamination on the surface of bedside curtain in a hospital in Shanghai and propose corresponding control measures for the replacement and cleaning frequency of hospital bedside curtain.Methods The bedside curtains were collected from department of respiratory medicine,infectious diseases,thoracic surgery,general surgery,and ICU from July to December 2018.Samples were collected continuously in 0 day,1 week,2 weeks,3 weeks,1 month,1.5 months,2 months,3 months,4 months,and 5 months after cleaning.Additional sampling was made in ICU on day 2 and day 4 of the first week of use.A total of 312 specimens were collected to monitor and analyze the total number of bacterial colonies.Results The bacterial count on hospital bedside curtain varied significantly with the time after replacing the curtain.The median number of bacterial colonies reached peak at 1.5 months in most clinical settings.The percentage of samples with total bacterial colony beyond limit was significantly different between clinical departments (χ2=17.726,P=0.001),specifically 31.67% in the department of infectious diseases,30.00% in the department of respiratory medicine,28.33% in both general surgical and thoracic surgery wards,and 5.56% in ICU.The total number of bacterial colonies on bedside curtain did not show significant difference between internal medicine and surgical wards (P>0.05),but significantly lower in ICU than in non-ICU wards (P<0.05).Conclusions The pollution of bedside curtain in this hospital is related to the environment of each department.The frequency of replacing bedside curtain should be reasonably adjusted according to specific situation in order to reduce potential hospital infections.
