Previous studies report conflicting results regarding the effects of ultraviolet (UV) light in reducing infections. This trial evaluated the impact of adding pulsed-xenon UV (PX-UV) to standard terminal cleaning in reducing environmentally implicated HAIs (eiHAIs).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>The Lowering the Acquisition of MDROs with Pulsed-xenon (LAMP) trial was conducted in 2 hospitals (15 inpatient wards) utilizing a cluster-randomized, controlled, double-blinded, interventional crossover trial comparing standard terminal cleaning followed by either PX-UV (intervention arm) or sham (control arm) disinfection. The primary outcome was incidence of eiHAIs from clinical microbiology tests on the fourth day of stay or later or within 3 days after discharge from the study unit. EiHAIs included clinical cultures positive for vancomycin-resistant enterococci, extended-spectrum beta-lactamase\u2013producing Escherichia coli or Klebsiella pneumonia, methicillin-resistant Staphylococcus aureus, and Acinetobacter baumannii, and stool polymerase chain reaction (PCR) positive for Clostridiodes difficile.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Between 18 May 2017 and 7 January 2020, 25 732 patients were included, with an incidence of 601 eiHAIs and 180 954 patient-days. There was no difference in the rate of eiHAIs in the intervention and sham arms (3.49 vs 3.17 infections\/1000 patient-days, respectively; RR, 1.10; 95% CI, .94\u20131.29; P = .23).
