- Abstract
Background The battle against nosocomial infections is ongoing, and the role the environment plays in these infections has been well established. Because only 50% of the items in a patient's room are adequately cleaned at the time of discharge, many hospitals are turning to "no-touch" systems to supplement their manual cleaning and disinfection protocols. Lumagenics introduces a safe, novel, handheld, low heat-generating Cool UV™ technology that can be used on a daily basis, while the patient is in the room. Methods Templates were drawn on Formica surfaces and inoculated with known amounts of epidemiologically important pathogens (EIP's) (i.e. MRSA, VRE, CRE Klebsiella pneumoniae , multidrug-resistant Acinetobacter baumannii , and Clostridioides difficile spores). After drying, each surface was exposed to the Cool UV™ at varying times and distances. After exposure, each surface was cultured with a Rodac plate and incubated according to standard microbiological procedures. Following incubation, all growth was quantitated and log10 reductions were calculated. Results Without an organic load, vegetative EIP's were reduced by an average of 3.63–5.08 log10 for 1 and 5 sec. respectively, at 1 inch and by an average of 2.10–4.08 log10 for 1 and 5 sec. respectively, at 5 inches (Table 1). C. difficile spores were reduced an average of 1.84–3.18 log10 in 10–60 secs from a distance of 1 inch, and an average of 1.21–2.58 log10 at 5 inches (Table 2). With an organic load (10% fetal calf serum), the log10 reduction for C. difficile spores was reduced ~0.94 log10, but the reduction achieved for the vegetative EIP's remained relatively unaffected. Conclusion Lumagenics' Cool UVTM technology, with short exposure times, reduced EIP's by levels similar to "no touch" room disinfection UV devices and may be a useful adjunct to daily cleaning and chemical disinfection.
