目的了解重庆市市级医院医务人员手机与手的带菌状况,探讨手卫生与手机污染状况的内在关联,为防止和减少院内感染提出有效措施和建议。方法从24家重庆市级医院重点科室选取111名医务人员作为观察对象,调查诊疗活动中手机使用状况;采用拭子涂抹法采集手和手机表面标本并进行细菌分离鉴定。结果部分医务人员存在手清洁消毒后仍使用手机现象。诊疗活动中手表面合格率为42.34%,清洁消毒后手表面合格率98.20%;手机表面合格率为80.18%。手表面检出15种43株潜在致病菌,手机表面检出18种55株潜在致病菌,两者的细菌构成比和检出率一致。同一人手机表面与手表面检出相同潜在致病菌一致性为38.89%。结论诊疗活动中手表面较手机表面污染更严重,两者间可能存在相互污染的情况。医务人员在做好手卫生的同时,应注意手机表面的清洁消毒,杜绝手机成为病原微生物传播媒介。 Objective To understand the carrier status of cell phones and hands of medical staff in municipal hospitals in Chongqing and to explore the inherent relationship between hand hygiene and cell phone pollution and to put forward effective measures and suggestions for preventing and reducing nosocomial infections. Methods A total of 111 medical staffs were selected from 24 key hospitals in Chongqing municipal hospitals to investigate the use of mobile phones during the diagnosis and treatment activities. Swabs were used to collect the surface samples of hand and cell phones and the bacteria were isolated and identified. Results Some medical staffs still use mobile phones after hand cleaning and disinfection. The qualified rate of the hand surface in the diagnosis and treatment activities was 42.34%, the pass rate of the hand surface after cleaning and disinfection was 98.20%; the passing rate of the mobile phone surface was 80.18%. A total of 43 potential pathogenic bacteria were detected on the surface of the hand and 18 potential pathogenic bacteria were detected on the surface of the cell phone. The bacterial composition ratio and the detection rate of the two were consistent. The same mobile phone surface and hand detection of the same potential pathogens consistency was 38.89%. Conclusion The surface of the hand-held handpiece is more polluted than the handpiece in the diagnosis and treatment activities. There may be mutual pollution between the two. Medical staff doing hand hygiene at the same time, should pay attention to the surface of the phone clean disinfection, to prevent mobile phones become the pathogenic microorganism media.
