Innovation in mobile communication technology has provided novel approaches to the delivery of healthcare and improvements in the speed and quality of routine medical communication. Bacterial contamination of mobile communication devices (MCDs) could be an important issue affecting the implementation of effective infection control measures and might have an impact on efforts to reduce cross-contamination. This review examines recent studies reporting bacterial contamination of MCDs, most demonstrating that 9-25% of MCDs are contaminated with pathogenic bacteria. We examine previously investigated risk factors for MCD contamination in addition to work on surface decontamination of the device. Recommendations to reduce contamination risks include staff education, strict hand hygiene measures, guidelines on device cleaning and consideration of the restrictions regarding use of mobile phone technology in certain high risk areas, for example, operating theatres, intensive care units and burns units. Further work is required to evaluate the benefit of such interventions on MCD contamination and to determine whether a link exists between contamination and subsequent patient infection.

    • "It is known that bacteria can survive on various surfaces including white coats[13], stethoscopes[14], adhesive tape[15], computer keyboards[16], elevator buttons[17], mobile communication devices[18], and ultrasound transducers[19], far longer than previously believed[20]. Most of the bacterial species characterized in the previous studies originate most likely from the normal skin flora such as coagulase-negative staphylococci16171821]. The link between human use and the composition of bacterial communities have also been reported on surfaces in kitchens and restrooms with bacterial species originating from human skin flora colonizing on kitchen surfaces, in agreement with frequent skin-to-surface occurrences222324.

    • "In addition to misuse of smartphone technology within the workplace, opponents also cite that they may pose a distraction within certain areas such as within theatres and local policies may need to be implemented to govern use.[29] [30] Although there are concerns whether these devices pose an additional risk of potentially pathogenic bacteria, this may be reduced by introducing comprehensive guidelines with regards to decontamination similar to that of medical equipment.[31] "

    ABSTRACT: Hospitals are increasingly looking for mobile solutions to meet their information technology needs. Medical professionals are using personal mobile devices to support their work, because of limitations in both time and space. Our aims were to assess smartphone use amongst UK surgical doctors, the prevalence of medical app use and online activity. A thirteen-item questionnaire was derived to identify the proportion of surgical doctors of all grades using smartphones within the workplace. The following factors were evaluated: use of medical apps; use of online medical resources and if users were willing to use their own smartphone for clinical use. A total of 341 participants were surveyed with a complete response rate: 93.5% of which owned a smartphone, with 54.2% of those owning medical apps and 86.2% using their device to access online medical resources. Junior doctors were more likely to use medical apps over their senior colleagues (p = 0.001) as well as access the Internet on their smartphone for medical information (p < 0.001). Overall, 79.3% stated that they would be willing to use their smartphone for clinical use, which was found not to be dependent on seniority (p = 0.922). Online resources contribute significantly to clinical activities with the majority of smartphone users willing to use their own device. The information gathered from this study can aid developers to create software dedicated to the smartphone operating systems in greatest use and to potentially increase the use of a bring your own device (BYOD) scheme.

    • "In addition, Penicillium funiculosum, the spores of which can cause asthma and rhinitis, has been found on display screens [5]. In order to remove harmful bacteria and fungi, washing of product surfaces using isopropyl alcohol [5] [6] is encouraged, but this method does not confer long-lasting antimicrobial activity. Therefore, products with potent antimicrobial activity and durability have recently been produced by incorporating Ag and Cu ions into the glass surface as nanosized particles, thus providing a large specific surface area [7] [8] [9] [10].

    ABSTRACT: We investigated the antimicrobial, cytotoxicity, skin irritation, and ion elution behaviors of glass doped with silver ions with respect to its application to electronic equipment such as phones and tablet screens. The microbes tested were Escherichia coli, Staphylococcus aureus, and Penicillium funiculosum. AgNO3 powder was spread on both sides of aluminosilicate glass, and it was heated to 250-280°C for 10min. Under optimized heating conditions (260°C, 10min), the antimicrobial activity of ion-exchanged glass against bacteria and fungi was over 99.9% after 24 weeks. The glass failed to irritate the skin of experimental animals and was considered non-cytotoxic. The maximum amount of Ag ions that were eluted from the ion-exchanged glass into drinking water was measured at 0.037±0.003μgL(-1), an amount which is several orders of magnitude below the standard limit of 0.1mgL(-1) in drinking water. Ag ion-exchanged glass had characteristics suitable for use as a display screen, such as a light transmittance of 90% and a surface roughness of 0.704nm. Our findings suggest that glass doped with silver ions is more hygienic than non-doped glass is, and should be applied to display screens and glassware. Copyright © 2015 Elsevier Inc.
