摘要

背景:手机是病原体的潜在宿主,也是医疗相关感染的来源。手机上的微生物比男人的马桶座、鞋底或门把手上的微生物还多。在检查病人时,频繁使用手机会传播细菌。尽管如此,非洲医护人员使用的手机受到细菌污染的证据还没有定论。因此,进行了这项荟萃分析和系统综述,以估计医护人员使用的手机中细菌污染的合并流行率和非洲最常见的细菌分离株。方法:我们使用PubMed/MEDLINE、POPLINE、HINARI、Science Direct、Cochrane Library数据库和Google Scholar从7月1日起系统检索了相关研究,2023年至2023年8月8日。我们纳入了观察性研究,这些研究报告了医护人员中手机细菌污染的流行率。DerSimonian随机Laird效应模型用于计算手机细菌污染合并流行率的效应估计值和95%置信区间(CI)。结果:在4544项检索到的研究中,26篇符合条件的文章被纳入荟萃分析,总样本量为2887名研究参与者。医护人员中手机细菌污染的合并患病率为84.5%(95%CI 81.7,87.4%;I2 = 97.9%,p值 结论:在这篇综述中,HCW使用的手机受到了各种细菌分离株的严重污染。最常见的细菌分离株是凝固酶阴性葡萄球菌、金黄色葡萄球菌和大肠杆菌。手机中细菌污染的流行率因国家和次区域而异。因此,医疗保健规划者和政策制定者应该制定规范,管理医护人员使用手机后的手部卫生和消毒。

Bacterial contamination of healthcare workers' mobile phones in Africa: a systematic review and meta-analysis.

Background: Mobile phones are potential reservoirs for pathogens and sources of healthcare-associated infections. More microbes can be found on a mobile phone than on a man's lavatory seat, the sole of a shoe, or a door handle. When examining patients, frequent handling of mobile phones can spread bacteria. Nevertheless, evidence of bacterial contamination of mobile phones used by healthcare workers in Africa was inconclusive. Thus, this meta-analysis and systematic review was conducted to estimate the pooled prevalence of bacterial contamination of mobile phones used by healthcare workers and the most frequent bacterial isolates in Africa.

Methods: We systematically retrieved relevant studies using PubMed/MEDLINE, POPLINE, HINARI, Science Direct, Cochrane Library databases, and Google Scholar from July 1, 2023 to August 08, 2023. We included observational studies that reported the prevalence of bacterial contamination of mobile phones among healthcare workers. The DerSimonian-random Laird's effect model was used to calculate effect estimates for the pooled prevalence of bacterial contamination in mobile phones and a 95% confidence interval (CI).

Results: Among 4544 retrieved studies, 26 eligible articles with a total sample size of 2,887 study participants were included in the meta-analysis. The pooled prevalence of mobile phone bacterial contamination among healthcare workers was 84.5% (95% CI 81.7, 87.4%; I2 = 97.9%, p value < 0.001). The most dominant type of bacteria isolated in this review was coagulase-negative staphylococci (CONS) which accounted for 44.0% of the pooled contamination rate of mobile phones used by healthcare workers, followed by Staphylococcus aureus (31.3%), and Escherichia coli (10.7%).

Conclusions: In this review, the contamination of mobile phones used by HCWs with various bacterial isolates was shown to be considerable. The most prevalent bacteria isolates were coagulase-negative staphylococci, Staphylococcus aurous, and Escherichia coli. The prevalence of bacterial contamination in mobile phones varies by country and sub-region. Hence, healthcare planners and policymakers should establish norms to manage healthcare workers' hand hygiene and disinfection after using mobile phones.
