The purpose of this study was to clarify the contamination of mobile phones shared in hospital wards and its relationship with the consciousness and behavior of nurses about biological cleanliness.
Samples from mobile phones were cultured to detect viable bacteria (n=110) and Staphylococcus aureus (n=54). A questionnaire survey was conducted on 110 nurses carrying mobile phones on the day of sampling.
Viable bacteria were detected on 79.1% of the mobile phones, whereas S. aureus was detected on 68.6%. All the nurses were aware of hand washing with water or alcohol after regular work, but 33.6% of the nurses were not conscious of hand washing with water or alcohol after using a mobile phone. There was a significant positive relationship between the frequency of using mobile phones and the number of hand washings with water or alcohol. A significant negative relationship was found between the detection of viable bacteria and the number of hand washings with alcohol. The results of logistic regression analysis showed that the detection of viable bacteria was related significantly with the number of hand washings with alcohol (Odds ratio, 0.350; 95%CI, 0.143-0.857) and that the detection of S. aureus was related significantly with the frequency of using mobile phones (Odds ratio, 0.183; 95%CI, 0.036-0.933).
It is important to be conscious of the fact that mobile phones shared in hospital wards are easily contaminated. Because hand washing with water or alcohol prevents the contamination of the mobile phones, nurses should take standard precautions after using mobile phones.
本研究旨在阐明医院病房中共享手机的污染情况及其与护士生物清洁意识和行为的关系。
对手机样本进行培养，以检测活菌（n = 110）和金黄色葡萄球菌（n = 54）。在采样当天，对110名携带手机的护士进行了问卷调查。
79.1%的手机检测到活菌，而68.6%检测到金黄色葡萄球菌。所有护士都知道在日常工作后用水或酒精洗手，但33.6%的护士在使用手机后没有用水或酒精洗手的意识。手机使用频率与用水或酒精洗手次数之间存在显著正相关。在活菌检测与酒精洗手次数之间发现显著负相关。逻辑回归分析结果显示，活菌检测与酒精洗手次数显著相关（优势比，0.350；95%置信区间，0.143 - 0.857），金黄色葡萄球菌检测与手机使用频率显著相关（优势比，0.183；95%置信区间，0.036 - 0.933）。
意识到医院病房中共享手机容易被污染很重要。由于用水或酒精洗手可防止手机污染，护士在使用手机后应采取标准预防措施。
