摘　　要：目的了解移动护理手持电脑设备(PDA)细菌污染现状并评价干预效果,为规范移动设备的卫生学管理提供依据。方法对各临床科室使用中的PDA现场卫生学采样并进行细菌定量检验,以实行PDA清洁消毒管理制度之前的采样标本为试验组,之后的采样标本为对照组,比较两组在干预前后的细菌检出情况。结果共采样PDA167台,其中试验组采样检测PDA 112台,30台检出细菌,阳性率26.79%;对照组采样检测55台,4台检出细菌,阳性率7.27%,两组细菌检出阳性率差异有统计学意义(χ2=8.66,P<0.01);共检出病原菌34株,以革兰阳性菌为主,排名前3位病原菌依次为枯草芽胞杆菌黑色变种芽胞、表皮葡萄球菌、屎肠球菌,分别占35.29%、20.59%、20.59%。结论使用中的PDA易受细菌污染,实行PDA定期清洁消毒管理,加强手卫生管理,可防止PDA成为新的医院感染传播媒介。OBJECTIVE To understand the current status of bacterial contamination of personal digital assistants（PDA）and evaluate the effects of interventions so as to provide guidance for standard hygiene management of mobile devices.METHODS The onsite hygienic sampling was carried out for the PDA that were in use in clinical departments and the quantitative bacterial test was conducted,the samples that were collected before the PDA cleaning and disinfection management system was implemented were assigned as the experimental group,while the samples that were collected after the system was implemented were set as the control group.The status of isolation of bacteria was observed and compared between the two groups before and after the interventions were taken.RESULTS A total of 167 sets of PDA were sampled,including 112 sets from the experimental group and 55 sets from the control group;the bacteria were isolated from 30 sets in the experimental group,with the positive rate26.79%,and the bacteria were isolated from 5sets in the control group,with the positive rate 7.27%;there was significant difference in the positive rate of detection of bacteria between the two groups（χ2=8.66,P〈0.01）.Totally 34 strains of pathogens were isolated,among which the gram-positive bacteria were dominant;Bacillus subtilis,Staphylococcus epidermidis,and Enterococcus faeciumranked the top 3species of pathogens,accounting for35.29%,20.59%,and 20.59%,respectively.CONCLUSIONThe PDA in use tend to be contaminated by bacteria.It is necessary to carry out regular cleaning and disinfection and strengthen the hand hygiene management so as to prevent the PDA from being a novel transmission medium.
