Brief Summary

Cell phones have become a fundamental accessory of our lives and clinical practice, often kept in contact with the body. Since most modern smartphones are equipped with touch screens, they can serve the function of reservoirs for pathogenic microorganisms; moreover, they can be the means of transmission of such microorganisms from the environment to humans. A number of observational studies are available in the literature evaluating the effectiveness of various sanitization methods in reducing the bacterial load of high-touch devices, both chemical and physical. To our knowledge, no real-world evidence is available comparing the residual effect of the two methods on the bacterial load of cell phones, since all available studies are carried out in the laboratory, with inoculums of predetermined bacterial loads whose suppression by the disinfectant is monitored over time, and involve laptops, tablets and keyboards.

Outcome Measures

Primary Outcomes (1)

• Average total bacterial load at 3 hours after sanitization

  The primary objective of the pilot study is to obtain preliminary data on the average total bacterial load at 3 hours after the sanitization intervention (70% isopropyl alcohol wipes or UVC box). These data will allow appropriate sizing of a subsequent trial to evaluate whether, on the cell phones of health care workers at the Fondazione Policlinico Universitario "A. Gemelli" IRCCS, wipes impregnated with 70% isopropyl alcohol are more effective than UVC ray boxes in reducing total bacterial load at 3 hours after sanitization for both isopropyl alcohol wipes and UVC box

  Samples will be collected immediately before and immediately after sanitisation and 3 hours after sanitisation.

Secondary Outcomes (1)

• Change in the average total bacterial load at 3 hours after sanitization

  Samples will be collected immediately before and immediately after sanitisation and 3 hours after sanitisation

Study Arms (2)

UVC box DEVICE

cellphones will be sanitised in a UVC box and total bacterial load will be assessed immediately before sanitation, immediately after sanitation and 3 hours after sanitation.
