Implementing and evaluating Ultraviolet-C mobile phone sanitisation for infection control in the intensive care unit.

A Glissner Cleanphone Ultraviolet-C (UV-C) device will be implemented in a prominent location in the intensive care unit for healthcare workers to self-administer cleaning of their mobile phones. This device applies UV-C radiation to the full 360-degree surface of mobile phones and is a touchless device, meaning no cross-contamination with clean hands. The device is 30cm tall, 26cm wide, and 14cm deep, making it portable and feasible to implement in clinical environments. Furthermore, this device uses an ultra-rapid cleaning time of only 10-seconds per application. Participants can use the device as often as they like throughout the implementation period and will be encouraged to do so via informational posters placed in the intensive care unit, and communication via meetings, emails, and in-services. Each Glissner Cleanphone device has been retrofitted with a magnetic counter which will record the number of times the device is utilised. This data will be downloaded from the device by the research team after the first 48 hours of implementation, and then weekly to track the amount of device usage over time, and map trends of acceptability, sustainability, and perceived utility. It is anticipated that the overall duration of implementation will be approximately 3-months This study will employ an iterative quality improvement methodology with the Plan-Do-Study-Act (PDSA) method used as the overarching implementation process. The barriers and facilitators of behaviour change and implementation which were identified through a previous staff survey will inform the preliminary iterative cycles of the PDSA method. Acceptability, sustainability, and perceived utility will be measured following the first PDSA cycle by a follow-up staff survey.
