摘要/Abstract

摘要： 目的：应用ATP 生物荧光法监测医务人员手机清洁度情况，观察酒精、湿巾清洁消毒手机的效果。方法：采用分层随机抽样法对医院180 名医务人员的手机清洁情况进行ATP 检测；随机用75% 酒精对30 部手机消毒，比较消毒后5min、10min、20min 的消毒效果；随机抽取60 部手机分为两组，比较普通湿巾和卫生湿巾清洁消毒手机的效果。结果：医务人员手机的清洁合格率为5.56%。特殊科室（重症监护室、感染科、血液净化科）医务人员手机ATP 值明显低于内科和外科医务人员的手机。在使用手机前洗手或用一次性薄膜套袋保持手机清洁的效果优于其他清洁消毒的方法（P <0.05），酒精消毒手机ATP 值明显低于未清洁消毒的手机ATP 值（P <0.05）；每日清洁消毒手机的清洁度明显优于每周清洁消毒手机（P <0.001）。酒精消毒的起效时间在10min 以上，消毒后10min、20minATP 值为（271.40±157.76）RLU、（344.30±147.79）RLU，达到清洁的标准（ATP 值<500RLU）。普通湿巾、卫生湿巾清洁消毒手机后ATP 值为（2129.90±1344.91）RLU 和（444.75±228.47）RLU，卫生湿巾的清洁效果明显优于普通湿巾（P <0.001），且接近清洁合格标准。结论：医务人员手机污染严重，应养成使用手机的良好卫生习惯，接打手机前洗手，每天用75% 酒精擦拭待干10min 或卫生湿巾对手机进行清洁消毒，使用一次性套袋，以减少病原体污染，保持手机的清洁。

Abstract: Objective: To investigate the cleanness of mobile phones in medical staff using ATP bioluminescence assay, and explore the effect of alcohol and wipes to clean and disinfect the cell phone. Methods: One hundred and eighty medical staffs were selected by stratified randomized sampling method. Their mobile phones' cleanliness was detected by ATP bioluminescence assay.After the detection, the investigator randomly cleaned 30 mobile phones with 75% alcohol, comparing the effect of disinfection after 5 minutes, 10 minutes and 20 minutes. They also randomly selected 60 mobile phones to compare the effect of cleaning and disinfection with general wipes and sanitary wipes. Results: The cleaning percentage of mobile phones of medical staffs was 5.56%.The ATP values of cell phones in special sections (such as Intensive Care Unit, Department of Infectious Diseases, and Blood Purification Center) were significantly lower than that in department of surgical and medical (P<0.05). Hands washing before using the phones or protecting them with a disposable bag were better than the other cleaning methods (P<0.05). The phones which were cleaned by alcohol had the significantly lower ATP value than the others (P<0.05). The daily cleaned phones were much cleaner than the weekly cleaned ones (P<0.001). The onset time of alcohol disinfection was above 10 minutes, the ATP value of 10 minutes and 20 minutes after alcohol disinfection were (271.40±157.76) RLU and (344.30±147.79) RLU, respectively. The disinfection effect of Alcohol met the standard of cleanness (ATP<500RLU). The ATP value were (2129.90±1344.91) RLU and (444.75±228.47) RLU,respectively, after using general wipes or sanitary wipes to clean and disinfect the phones. The cleaning effect of sanitary wipes was better than general wipes (P<0.001), and close to the standard of cleanliness. Conclusion: The mobile phones of medical staff were seriously polluted. Some good health habits, including hands washing before touching the phones, daily cleaning the phones with alcohol or sanitary wipes, and using protective disposable bags, could keep the cleanness of cell phones and decrease the pathogen pollution.
