Teacher: Now, understand the problem? Solve this instance: Health care-associated infections result in significant patient morbidity and mortality. Although cleaning can remove pathogens present on hospital surfaces, those surfaces may be inadequately cleaned or recontaminated within minutes. Because of copper's inherent and continuous antimicrobial properties, copper surfaces offer a solution to complement cleaning. The objective of this study was to quantitatively assess the bacterial microbial burden coincident with an assessment of the ability of antimicrobial copper to limit the microbial burden associated with 3 surfaces in a pediatric intensive care unit.", 'A pragmatic trial was conducted enrolling 1,012 patients from 2 high acuity care units within a249-bed tertiary care pediatric hospital over 12 months. The microbial burden was determined from 3frequently encountered surfaces, regardless of room occupancy, twice monthly, from 16 rooms, 8outfitted normally and 8 outfitted with antimicrobial copper.', 'Copper surfaces were found to be equivalently antimicrobial in pediatric settings to activities reported for adult medical intensive care units. The log10 reduction to the microbial burden from antimicrobial copper surfaced bed rails was 1.996 (99%). Surprisingly, introduction of copper objects to 8study rooms was found to suppress the microbial burden recovered from objects assessed in control rooms by log10 of 1.863 (73%).
Student:
Are copper surfaces associated with significantly lower concentrations of bacteria on selected surfaces within a pediatric intensive care unit?
