Mobile phones (MPs) of healthcare workers (HCWs) may represent an important source of transmission of infectious agents. This longitudinal study documents the contamination of these tools. Ten MPs handled by senior pediatricians were sampled once a week during 23 weeks in three pediatric wards of the University Hospital of Saint-Etienne, France. Cultures were performed for bacteria and multiplex PCR assays for a panel of respiratory and enteric viruses. A questionnaire on hygiene habits regarding phoning and care was filled-in by pediatricians before and after the study. From a total of 230 samples, 145 (63%) were contaminated by at least one pathogen. The MPs from emergency departments were the most impacted. Viruses were detected in 179 samples; bacteria were isolated in 59 samples. Contamination increased during the winter epidemic peak. A cross-contamination by between hands and MPs of different HCWs was demonstrated. The communication of the study results influenced the hygiene behaviors. This study highlights the contamination of MPs by pathogens that are resistant in the environment, and its sustainability along the winter season. The role of MPs as vectors of nosocomial infection needs to be better investigated.
医护人员的手机可能是传染源的一个重要传播途径。这项纵向研究记录了这些工具的污染情况。在法国圣艾蒂安大学医院的三个儿科病房中，对高级儿科医生使用的10部手机在23周内每周采样一次。进行了细菌培养以及针对一组呼吸道和肠道病毒的多重聚合酶链反应检测。在研究前后，儿科医生填写了一份关于打电话和护理卫生习惯的问卷。在总共230个样本中，145个（63%）被至少一种病原体污染。急诊科的手机受影响最大。在179个样本中检测到病毒；在59个样本中分离出细菌。在冬季流行高峰期间污染增加。不同医护人员的手与手机之间存在交叉污染。研究结果的传达影响了卫生行为。本研究强调了手机被环境中耐药病原体污染的情况及其在冬季的持续性。手机作为医院感染传播媒介的作用需要进一步深入研究。
