Who is responsible for cleaning computers workstations in a Hospital?
A Potential Source of Pathogen Transmission Because many hospitals, clinics and care centers do not have routine cleaning of IT equipment, there is a high risk of contamination with pathogenic bacteria from the hands of healthcare workers (1). What is your hospitals protocol for IT equipment cleaning? 17 hospital touch screens cultured and identified pathogens (3). • C. diff. • VRE Study of 25 keyboards. All tested positive for growth of two or more microorganisms (2). • Klebsiella Sources: 1 Bures S, Fishbain JT, Uyehara, CFT, Parker JM, Berg BW.

Surface Sanitizing Today A disinfectant takes 3 to 4 minutes in a liquid state to completely eliminate pathogens and may take up to 10 minutes for more resistant pathogens. A quick wipe with a damp towel does not clean.
What is UVC?
UVC Technology Has Germicidal Effects “The incidence of target organisms among exposed patients was significantly lower after adding UV-C light to standard cleaning strategies. Ultraviolet disinfection is powerful and effective.” Source: BET-R study funded (in large part) by the Centers for Disease Control & Prevention (CDC)
Clinical Study Purpose: Demonstrate Efficacy of UVC Disinfection Device • Study located at HCA Houston Healthcare Southeast in the neurology unit and Intermediate Medical Care Unit (IMCU) • Study involved 52 computer workstations, that included 17 mobile computing carts and 35 in-room wall mounted workstations • Study aimed to prove automated UVC disinfection device is: • Effective at eliminating harmful pathogens • A complement to existing disinfection and hand hygiene protocols

Installing UVC Disinfection Device to Carts & Cabinets
Product Details • Motion activated for safe deployment of UV-C light • Automated cleaning cycle • Ran for 5 minutes every hour if no motion • If there was motion it waiting 1 minute for no motion and then ran for 5 minutes • 60 cm active cleaning area range • Internal memory and built-in audit trail • Different brackets for different applications • Flexible workspace configurations • Plugs into USB 3.0 port of power outlet • Over 3 year life on bulb based on normal hospital usage (2 year warranty).
How does it work? In independent testing by NSF International there was the following results: - 91.1% reduction in C. diff after 10 minutes of UVC exposure - 99.996% reduction in C. diff after 30 minutes of UVC exposure - 99.996% reduction in MRSA after 10 minutes of UVC exposure - 99.998% reduction in MRSA after 15 minutes of UVC exposure
Clinical Study Data Collection
Clinical Study Results
Safety • Automated ultraviolet disinfection cycles • Used a high speed camera to evaluate UVC Exposure Results exposure time and dosage 13.3 seconds of 30 uW/cm2, • Built-in motion sensor for safe operation resulting in just • After task is completed and if no motion is under 7% of the detected after a specified amount of time, maximum dosage a new additional cleaning cycle begins recommendation • After that cleaning cycle completes set by the NIOSH for an eight-hour shift. without interruption, UV-CLEAN reverts to operating under the scheduled cleaning cycles timeline
Further implementation of UV-Clean devices after the study.
