Abstract

BACKGROUND

Assuming that hygiene measures have improved significantly due to COVID-19, we aimed to investigate bacterial colonization on smartphones (SPs) owned by healthcare workers (HCWs) before and during the pandemic.

METHODS

Employing a before-and-after study design, randomly selected HCWs were included. Devices underwent sampling under real-life conditions, without prior manipulation. Swabs were collected in 2012 (pre-pandemic) and 2021 to determine microbial colonization. Isolates were identified by MALDI-TOF mass spectrometry and underwent microbiological susceptibility testing.

RESULTS

The final analysis included 295 HCWs (67% female, mean age 34 years) from 26 wards. Bacterial contamination was present on 293 of 295 SP screens (99.3%). The proportion of clinically relevant bacterial pathogens (eg Staphylococcus aureus, enterococci, Enterobacterales, non-fermenting bacteria) ranged from 21.2% in 2012 to 39.8% in 2021. Resistance profiles revealed a proportion of multidrug-resistant bacteria such as MRSA and VRE of less than 2%. The comparison of before-and-after sampling showed a significant increase in smartphone use during work from 2012 to 2021 with a simultaneous increase in cleaning intensity, probably as a result of the COVID-19 pandemic.

CONCLUSIONS

Bacterial contamination of SPs within the hospital is of concern and can serve as a source of cross-contamination. Hence, in addition to excellent hand hygiene, SPs must be carefully disinfected after handling in healthcare. Behavioral changes related to the COVID-19 pandemic could have a significant impact if implemented sustainably in everyday clinical practice.

摘要

背景

假设由于 COVID-19，卫生措施有了显著改善，我们旨在调查大流行前后医护人员（HCWs）拥有的智能手机（SP）上的细菌定植情况。

方法

采用前后对照研究设计，随机选择 HCWs 进行研究。在实际情况下，在不事先干预的情况下对设备进行采样。于 2012 年（大流行前）和 2021 年采集棉签以确定微生物定植情况。采用 MALDI-TOF 质谱法对分离株进行鉴定，并进行微生物药敏试验。

结果

最终分析纳入了 26 个病房的 295 名 HCWs（67%为女性，平均年龄 34 岁）。295 个 SP 屏幕中有 293 个存在细菌污染（99.3%）。临床相关细菌病原体（如金黄色葡萄球菌、肠球菌、肠杆菌科、非发酵菌）的比例从 2012 年的 21.2%上升到 2021 年的 39.8%。耐药谱显示，耐甲氧西林金黄色葡萄球菌（MRSA）和万古霉素耐药肠球菌（VRE）等多药耐药菌的比例不到 2%。与采样前后的比较显示，2012 年至 2021 年期间，工作期间智能手机的使用显著增加，同时清洁强度也随之增加，这可能是 COVID-19 大流行的结果。
