Mobile phones improve the efficiency of clinical communication and are increasingly involved in all areas of healthcare delivery. Despite this, healthcare workers' mobile phones provide a known reservoir of pathogenic bacteria, with the potential to undermine infection control efforts aimed at the reducing bacterial cross-contamination in hospitals. This potential could be amplified further when employers require doctors to carry additional electronic devices for communication, without concurrently providing appropriate guidance on decontamination or use.
Eighty-seven on-call doctors' mobile phones were sampled for bacterial growth prior to, and 12 h after, a cleaning intervention involving 70% isopropyl alcohol.
Seventy-eight percent of doctors were aware that mobile phones could carry pathogenic bacteria, but only 8% cleaned their phones regularly. The cleaning intervention reduced the number of phones that grew bacteria by 79% (55% [48 of 87] before versus 16% [14 of 87] after cleaning). Eight percent of the phones grew Staphyloccus aureus, and 44.8% of phones grew Gram-positive cocci. All S. aureus isolates were methicillin-sensitive. Bacterial contamination was not associated with gender, specialty, or seniority of the phone user (p>0.05).
Simple cleaning interventions can reduce the surface bioburden of hospital-provided doctors' mobile phones and therefore the potential for cross-contamination. This cleaning intervention is inexpensive, easily instituted, and effective. Healthcare workers should carry the minimum number of electronic devices on their person, maintain good hand hygiene, and clean their device appropriately in order to minimize the potential for cross-contamination in the work place.
手机提高了临床沟通的效率，并越来越多地参与到医疗保健服务的各个领域。尽管如此，医护人员的手机仍是已知的致病菌储存库，有可能破坏旨在减少医院细菌交叉污染的感染控制工作。当雇主要求医生携带额外的通讯电子设备，而没有同时提供适当的消毒或使用指导时，这种潜在风险可能会进一步放大。
在清洁干预措施（包括 70%异丙醇）之前和之后 12 小时，对 87 名值班医生的手机进行细菌生长采样。
78%的医生意识到手机可能携带致病菌，但只有 8%的人定期清洁手机。清洁干预措施使细菌生长的手机数量减少了 79%（清洁前为 55%[87 部手机中的 48 部]，清洁后为 16%[87 部手机中的 14 部]）。8%的手机生长出金黄色葡萄球菌，44.8%的手机生长出革兰氏阳性球菌。所有金黄色葡萄球菌分离株均对甲氧西林敏感。细菌污染与性别、专业或手机使用者的资历无关（p>0.05）。
简单的清洁干预措施可以减少医院提供的医生手机表面的生物负荷，从而降低交叉污染的可能性。这种清洁干预措施成本低廉，易于实施，且效果显著。医护人员应尽量减少随身携带的电子设备数量，保持良好的手部卫生，并适当清洁设备，以最大程度地减少工作场所的交叉污染风险。
