    摘要:

    目的了解医院病房使用的个人数字助理设备(PDA)表面的洁净度状况,评价采用消毒湿巾对PDA表面进行清洁消毒的干预效果。方法2016年1—3月选择某院50个临床科室病房每日使用的83台手持PDA作为对照组,同时选择病房同等使用环境下的83台PDA作为干预组(使用卡瓦布进行清洁消毒),采用ATP生物荧光法检测两组PDA表面的清洁状态。结果以ATP生物荧光检测值≤100 RLU/100 cm2为合格,对照组ATP读数范围为189~3 379 RLU,无1例合格;干预组消毒后合格率为90.4%(75例)。在使用卡瓦布消毒湿巾对PDA表面进行清洁消毒后,不同科室干预组PDA表面ATP检测值(中位数:18~28 RLU) 均低于对照组(中位数:290~339  RLU),差异均有统计学意义(均P<0.05)。结论医院病房使用的PDA微生物污染情况较为普遍,含有季铵盐的消毒湿巾可用于PDA表面清洁消毒。

    Abstract:

    ObjectiveTo investigate the cleanliness status of personal digital assistant (PDA) surfaces, and observe the effect of disposable antiseptic wipes on the cleaning and disinfection of PDA surface. MethodsFrom January to March 2016, 83 daily used handheld PDA in 50 clinical wards of a hospital were as control group, 83 PDA disinfected by disposable antiseptic wipes(CaviWipes) and used in the same environment of the ward at the same time were selected as the intervention group, cleanliness status of PDA surfaces of two groups were detected by adenosine triphosphate (ATP) bioluminescence assay. ResultsTaken a cutoff value≤100 RLU/100 cm2 as qualified standard of cleanliness, none of PDA in control group was qualified with ATP bioluminescence reading ranged from 189 to 3 379 RLU; after disinfection with CaviWipes, the qualified rate of intervention group was 90.4%(n=75), ATP detection value of PDA surface in all departments were significantly lower than control group(median: [18-28] RLU vs [290-339] RLU, all P<0.05). ConclusionMicrobial contamination on PDA used in hospital wards is common, antiseptic wipes containing quaternary ammonium salt can be used for cleaning and disinfecting surface of PDA.
