  • Background: Automated Ultraviolet-C (UV-C) light disinfection is proven to reduce the bioburden of bacterial contaminants. The use of these automated disinfection systems has also been linked to decreases in healthcare acquired infections (HAIs), such as MRSA and C. difficile. Here we evaluated the efficacy of the automated UV-C triple emitter system, which has been designed to accomplish room disinfection more effectively and in less time. Catheter associated UTI (CAUTI) and central line associated bloodstream infection (CLABSI) rates were evaluated in the Medical ICU (MICU) secondary to consistent application of UV-C light disinfection.

    Methods: Each discharge room was effectively chemically disinfected, curtain changed, terminally cleaned, and treated with UV-C light. UV-C light was available for use in the MICU as needed for every discharge during the study period. Protocols for MICU, housekeeping, and bed management impacting admission and discharge were altered to accommodate this technology. Working collaboratively with MICU staff regarding these processes, proved to be instrumental in outcomes. The UV-C light disinfection system was consistently applied to the MICU from 3/2015 – 7/2015 as an adjunct to the housekeeping program already in place. NHSN SIR metrics were used to measure the impact of UV-C light disinfection on CAUTI and CLABSI rates.

    Results: The MICU experienced a statistically significant reduction in CAUTI incidence (SIR =0.00, p=0.01, SIR95CI =, 0.673) and a measurable reduction in CLABSI incidence (SIR=0.036, p=0.29, SIR95CI = 0.018, 1.763) for the study period when UV-C light disinfection was consistently used. When UV-C light disinfection was less vigorously applied, CAUTI and CLABSI increased, although not statistically significant (CAUTI SIR = 1.44, p=0.41, SIR95CI = 0.527, 3.190; CLABSI SIR = 1.81, p=0.21, SIR95CI = 0.662, 4.004).

    Conclusion:  Prior to the new UV-C light disinfection program at Jersey Shore University Medical Center (JSUMC), the Infection Control Committee was striving to reduce the incidence of both CLABSI and CAUTI for over a year. A CAUTI Action Plan had been in place since fourth quarter 2014 and several nursing improvements to patient care had already been implemented. The addition of the automated UV-C disinfection system further reduced both CAUTI and CLABSI incidence when applied consistently in the MICU.
