Objective:
To assess the effect of the COVID pandemic on reading room cleanliness by analyzing cleaning behaviors of the radiology workstations in a tertiary academic institution.

Materials and Methods:
A prospective study was performed on workstations by radiologists at an academic teaching hospital from 2017-2020. A baseline evaluation was performed on frequently used workstations throughout reading rooms to serve as a representative sample. Five separate sites on each workstation (phone receiver, phone keypad, mouse, microphone, and keyboard) were marked with photo luminescent material before the start of the workday and without the radiologists’ knowledge. At the end of the workday, each utilized workstation was evaluated with an ultraviolet black light to determine whether the workstations showed evidence of cleaning by their user. Monitoring of workstation cleanliness in reading rooms in the radiology department was performed after initiatives including installing cleaning supplies, hand-sanitizing stations, instructional placards, and providing educational lectures. As a result of the interventions, cleaning supplies and hand-sanitizing stations were routinely stocked and present in the reading rooms. Workstations were assessed over time, both pre- and post-COVID-19.

Results:
Initial pre and post intervention workstation data was gathered. Before any attempted intervention, 24 workstations were evaluated, with a total of 3 workstations being cleaned (12.5%). After the installation of sanitizing materials, 23 workstations were evaluated and 4 were cleaned (17.4%). Finally, an educational intervention was performed and workstations were again evaluated at monthly intervals thereafter. Six months post-educational intervention 32 workstations were evaluated and 14 of those had been cleaned (43.8%). In August 2020 during the COVID-19 pandemic, 20 workstations were evaluated and 5 had been cleaned (25%).

Conclusion:
Nosocomial infections continue to be at the forefront of hospital focus as a major contributor to inpatient morbidity and mortality. In the current climate of a global pandemic, this focus and its importance cannot be under-stated. As environmental surfaces continue to play an important role in the transmission of healthcare associated pathogens, we believe an analysis of the radiologist’s primary environment, the workstation, is vital to maintaining the health of ourselves, our colleagues, and our patients. Our assumption that the current global pandemic would lead to an overall increase in reading room cleaning behaviors was disproven. There are several potential factors contributing to this result including amount of time since initial educational intervention as well as actual or perceived lack of accessibility to cleaning supplies in the midst of the global pandemic. Our goal is to continue this initiative with an additional educational intervention and subsequent re-evaluation of cleaning practices to sustainably improve radiologists’ workstation disinfection at our institution and protect staff and patients against healthcare associated infections.
