ICID 2014:医护手机可成为院感的污染源

医护手机可成为院感的污染源

德国医院的研究显示医护人员使用的智能手机和平板电脑至少被一个病原体污染。德国莱比锡圣乔治大学的医学生罗密温德勒是该研究的主要人员。他表示医护人员可能会将这些病原体传递给患者,增加患者感染的风险。

护士和医生可能会在高风险区域,如手术室和ICU使用自己的私人电话。这种行为可能使病人处于危险之中,因为我们不会考虑这些细小的问题。这项研究结果发表在第16届国际传染病大会上(16th International Congress on Infectious Diseases,ICID)。

细菌污染情况


该研究的目的是评价智能手机和平板电脑表面的细菌污染情况,并确定14天的清洗周期是否会影响细菌污染情况。

研究人员检测了清洗方案实施前后每个设备表面的微生物污染情况。细菌培养的结果用半定量的菌落形成单位计数进行分析,微生物的确定使用传统的微生物鉴定方法。

基线的情况如下:101部智能手机中的100部至少含有1个病原体,20个平板电脑中有19个至少含有1个病原体。约55%的触摸屏含有超过1个病原体。大多数病原体是细菌,这些细菌可引起危重病人的严重感染,包括金黄色葡萄球菌,肠球菌和肠杆菌。研究者将这些病原体定义为有意义的病原体。15.8%的智能手机屏幕,25.0%的平板电脑屏幕至少存在1种上述病原体。其中1个平板电脑上含有耐甲氧西林的葡萄球菌。在经过2个星期的清洗之后,细菌污染情况没有显着降低。具体来说,智能手机屏幕病原体的数量降低7.7%,平板电脑屏幕降低22.2%。

研究人员对这些设备的拥有者进行了问卷调查。问卷的问题包括卫生习惯,如多久清洗一次自己的设备。

结果显示,65%的平板电脑用户和约76%的智能手机有时会清理他们的设备。20%的平板电脑用户和10%的智能手机用户会经常清洗他们的设备。但10%的平板电脑用户和8%的智能手机用户承认,他们从来没有清理自己的设备。

温德勒强调:这和手部卫生是同样的问题。如果你要在工作时使用手机或其他设备,你必须在回家前对它进行清洗。否则,它将成为传染源。特殊的消毒湿巾适合清洁任何触摸屏。

来自澳大利亚新南威尔士州大学的阿布拉艾哈迈德医师表示:这是一项很好的研究。他本来希望看到触摸屏病毒污染的水平。他对流感病毒特别感兴趣,所以他对流感病毒是否会污染这些设备很感兴趣。
