浙江省某医院NICU医务人员手机卫生调查

Hygiene of cell phones of health care workers from NICU of a hospital in Zhejiang Province

目的 了解医院新生儿重症监护病房(NICU)工作人员手机的污染情况,探讨手机定期消毒频率对手机卫生的影响,为降低手机污染途径提供参考依据。方法 通过调查问卷了解医院NICU医务人员手机使用现况;采用无菌海绵棒对不同消毒频率的三组工作人员手机采样进行病原菌培养;通过χ^(2)检验分析工作人员手机使用习惯对手机卫生的影响、不同消毒频率对手机卫生的影响。结果 本研究共计调查46名工作人员,调查对象全部使用触屏手机,97.83%的工作人员工作时有使用手机的现象,17.39%的人经常使用;13.04%的人在使用完手机后从不进行手卫生,仅有1人(2.17%)每次会进行手卫生;有69.57%的人手机定期清洁的频率为<1次/天;大部分工作人员手机清洁的方式采用一次性消毒湿巾;有15.22%的工作人员会对手机使用一次性保护套;对其中32名工作人员手机进行采样,抽样合格率为34.38%,未分离到致病菌。使用一次性保护套能较好的保持手机相对清洁;不同消毒频率手机卫生合格率比较差异无统计学意义。结论 定期对手机进行清洁消毒能够有效地降低手机表面细菌的定植,使用一次性保护套能较好的保持手机相对清洁。

OBJECTIVE To understand the status of pollution of cell phones of health care workers from neonatal intensive care unit(NICU) and explore the effect of frequency of regular disinfection on hygiene of cell phones so as to reduce the pollution of cell phones. METHODS A questionnaire survey was conducted for the status of use of cell phones among the health care workers, the samples were collected from the cell phones of three groups of health care workers that were disinfected with different frequencies by using sterile sponge sticks. Chi square test was carried out to analyze the impact of use habit of cell phones on the hygiene and the impact of different frequencies of disinfection on the hygiene of cell phones. RESULTS A total of 46 health care workers were enrolled in the study, all of them used touch-screen cell phones, 97.83% of the health care workers used the cell phone when working, 17.39% used sometimes;13.04% of the health care workers never carried out hand hygiene after they used cell phones, only 1(2.17%) health care worker carried out hand hygiene every time after use;the frequency of regular cleaning of cell phones was less than once per day among 69.57% of the health care workers. The majority of the health care workers used disposable disinfectant wipes for the cleaning of cell phones;15.22% of the health care workers used disposable protective covers. The cell phones of 32 health care workers were sampled, the qualified rate of the samples was 34.38%, and pathogens were not isolated. The cell phones maintained clean by using the disposable protective covers. There was no significant difference in the qualified rate of hygiene among the cell phones with different frequencies of disinfection. CONCLUSION The regular cleaning and disinfection of the cell phones may effectively reduce the bacterial colonization on the surfaces of cell phones, and the use of disposable protective covers may keep the cell phones relatively clean.
