Electronic devices have become one of the most essential accessories being used in hospitals. Those devices increase the communication and contact making healthcare delivery more efficient and quality service oriented. The study was designed to collect reliable information about the spreading of pathogens through electronic devices especially in sensitive departments. The objectives of this study were to evaluate the bacterial colonization of electronic devices and determine the effectiveness of disinfection with alcohol 70% (/) to reduce the bacterial colonization of electronic devices. It was a cross-sectional study where samples were collected by means of moistened swabs in sterile saline solution from 30 electronic devices used by healthcare workers at Ruhengeri Referral Hospital within four different units: maternity, neonathology, intensive care, and theater room. To evaluate the effects of disinfection using 70% isopropyl alcohol, the second sample collection was carried out after decontamination with 70% isopropyl alcohol. Samples were analyzed in the microbiology lab of INES-Ruhengeri. The result showed that was the most predominant with 22.5%. and spp. were 12.5%; , coagulase-negative Staphylococci, and were 10%; was 7.5%; spp. and spp. were at 5%. The lowest prevalence was 2.5% of spp. and spp. The threat of dissemination of isolated microorganisms is valid, since all devices evaluated in this study showed bacterial contamination of species associated to hospital-acquired infections. Special care should be taken when using electronic devices in healthcare settings in addition to disinfection to reduce the risk of transmission of bacterial agents. Further studies should evaluate the antibiotic susceptibility for better conclusive results since all isolated bacteria in this study were subjected to high resistance and were associated with nosocomial infections.
电子设备已成为医院中使用最广泛的设备之一。这些设备增加了沟通和联系，使医疗保健服务更加高效和以质量为导向。本研究旨在收集有关通过电子设备传播病原体的可靠信息，特别是在敏感部门。本研究的目的是评估电子设备的细菌定植情况，并确定用 70%酒精消毒以减少电子设备细菌定植的效果。这是一项横断面研究，通过在鲁亨盖里转诊医院的四个不同科室（妇产科、新生儿科、重症监护室和手术室）的 30 名医护人员使用的电子设备上用无菌生理盐水湿润的拭子收集样本。为了评估用 70%异丙醇消毒的效果，在进行 70%异丙醇消毒后进行第二次样本采集。样本在 INES-Ruhengeri 的微生物实验室进行分析。结果表明，最常见的是 22.5%的 。和 spp. 为 12.5%； 、凝固酶阴性葡萄球菌和 为 10%； 为 7.5%； spp. 和 spp. 为 5%。最低的流行率为 2.5%的 spp. 和 spp. 由于所有在本研究中评估的设备都显示出与医院获得性感染相关的微生物的细菌污染，因此隔离微生物传播的威胁是有效的。除了消毒之外，在医疗保健环境中使用电子设备时应格外小心，以降低细菌传播的风险。应进行进一步的研究以评估抗生素敏感性，以获得更好的结论，因为本研究中所有分离的细菌都表现出高度耐药性，并且与医院获得性感染有关。
