Extra-European studies report high rates of multi-drug resistant bacteria colonization of healthcare workers' mobile phones in intensive care units. We aimed to assess the prevalence of bacterial colonization of healthcare workers' mobile phones in an intensive care unit in France and the effectiveness of a sanitization product. We designed a prospective, monocentric study in a 15-bed intensive care unit within a 300-bed private hospital. Bacterial colonization was assessed on 56 healthcare workers' mobile phones immediately before and 5 min after sanitization of the phones with bactericidal wipes. The mobile phones of 42 administrative staff acted as controls. All mobile phones in both groups were colonized. Healthcare workers' phones had a higher number of different bacterial species per phone (2.45 ± 1.34 vs. 1.81 ± 0.74, p = 0.02). Colonization with pathogens did not differ significantly between healthcare workers' and controls' phones (39.3% vs. 28.6%, p = 0.37). Excluding coagulase negative Staphylococcus, Staphylococcus aureus was the most common pathogen found in both groups (19.6% and 11.9%, p = 0.41). Only one healthcare workers' mobile phone was colonized by methicillin-resistant Staphylococcus aureus, and no other multi-drug resistant bacteria was detected. No covariate was associated with pathogen colonization. After sanitization, 8.9% of mobile phones were sterilized, and colonization with pathogenic bacteria decreased (21.4% vs. 39.3%, p = 0.04) as did the number of CFUs/mL (367 ± 404 vs. 733 ± 356, p < 0.001). Colonization of intensive care unit healthcare workers' and administrative staff's mobile phones was similar. Colonization with pathogens was frequent but colonization with multi-drug resistant bacteria was rare. Disinfecting the phones with bactericidal wipes is not completely effective. Specific sanitization protocols and recommendations regarding the management of healthcare workers' mobile phones in intensive care units should be developed. Additionally, good hand hygiene after touching mobile phones should be kept in mind to prevent cross-infections.
欧洲以外的研究报告称，在重症监护病房，医护人员的手机上存在多种耐药菌定植的高比率。我们旨在评估法国一家重症监护病房医护人员手机的细菌定植率以及一种消毒产品的有效性。我们设计了一项前瞻性、单中心研究，在一家 300 床私立医院的 15 床重症监护病房进行。在使用杀菌湿巾对手机进行消毒前后，立即对 56 名医护人员的手机进行细菌定植评估。对照组为 42 名行政人员的手机。两组所有手机均有定植。医护人员手机每部手机的细菌种类更多（2.45 ± 1.34 与 1.81 ± 0.74，p = 0.02）。医护人员手机与对照组手机的病原菌定植无显著差异（39.3% 与 28.6%，p = 0.37）。排除凝固酶阴性葡萄球菌后，金黄色葡萄球菌是两组中最常见的病原体（19.6% 和 11.9%，p = 0.41）。只有一部医护人员手机定植了耐甲氧西林金黄色葡萄球菌，未检出其他多重耐药菌。无协变量与病原菌定植相关。消毒后，8.9%的手机达到无菌，病原菌定植减少（21.4% 与 39.3%，p = 0.04），CFU/mL 也减少（367 ± 404 与 733 ± 356，p < 0.001）。重症监护病房医护人员和行政人员的手机定植情况相似。病原菌定植较为常见，但定植多重耐药菌较为罕见。使用杀菌湿巾消毒手机并不完全有效。应制定专门的消毒方案和建议，规范重症监护病房医护人员手机的管理。此外，应牢记接触手机后保持良好的手部卫生，以防止交叉感染。
