摘　　要：目的为了解某市市级医院医务人员手机使用及其表面带菌状况,探讨手机使用行为和带菌状况的影响因素。方法2016年4—6月对某市24所市级医院中111名医务人员进行问卷调查、现场观察及手机表面采样。结果共发放并回收有效问卷111份,回收率及有效率均为100.00%。调查对象平均年龄为(32.00±9.03)岁,以女性和护士为主。调查对象中95.50%使用触屏手机,24.32%的医务人员诊疗时有使用手机的现象,65.77%的医务人员每天手机使用时间>2 h,93.69%对手机进行过清洁消毒。98.20%医务人员认为手机表面存在病原微生物。共采集111份手机表面样本,合格率80.18%,污染率95.50%,平均菌落数为2.90 CFU/cm^2,最大细菌含量为111.60 CFU/cm^2。44份手机样本表面共检出18种55株致病菌或条件致病菌。年龄、性别、职业是手机使用行为和对手机认知态度的影响因素。性别、职业、手机使用持续时间的手机表面合格率分别比较,差异均有统计学意义(均P<0.05);年龄、性别、职业、手机使用持续时间、是否使用手机壳/套的手机表面细菌染菌量分别比较,差异均具有统计学意义(均P<0.05)。结论手机表面存在的潜在致病菌可能会通过医务人员诊疗过程中使用手机的行为引发医院感染。ObjectiveTo understand the status of mobile phone use and bacterial carriage on surface of mobile phones used by health care workers(HCWs)in municipal hospitals in a city,explore the influencing factors of mobile phone use behavior and bacterial carriage status.MethodsIn April June,2016,111HCWs in24hospitals in a city were performed questionnaire survey,on site observation,and sampling of mobile phone surface.ResultsA total of111(100.00%)available questionnaires were distributed and returned.The average age of the respondents were(32.00±9.03)years old,female and nurses were predominant.95.50%of respondents used touch screen mobile phones,24.32%used mobile phones during diagnosis and treatment,65.77%used mobile phone>2hours every day,93.69%cleaned and disinfected mobile phones,98.20%thought that pathogenic microorganisms exited on the surface of mobile phones.A total of111mobile phone surface specimens were collected,the qualified rate was80.18%,contamination rate was95.50%,average colony number was2.90CFU/cm2,the maximum bacterial content was111.60CFU/cm2.Among44specimens of mobile phone surface,55strains of18species of pathogenic bacteria or opportunistic pathogenic bacteria were detected.Age,gender,and occupation were the influencing factors of mobile phone use behavior and attitude;qualified rates were all significantly different among mobile phones used by HCWs of different gender,occupation,and duration of mobile phone use(all P<0.05);bacterial contamination on the surface of mobile phones used by HCWs of different age,gender,occupation,duration of mobile phone use,and whether to use the phone shell/set were significantly different respectively(all P<0.05).ConclusionPotential pathogens on the surface of mobile phones may cause healthcare associated infection through the use of mobile phones by HCWs during the process of medical diagnosis and treatment.
