Clinical Trial Summary

CUPRIC is an investigator initiated and conducted, prospective, quasi-experimental study to determine whether the combined use of copper-alloyed objects plus copper-enriched textiles reduce the burden of MDRO colonization and HAIs incidence in the critically ill population.

Description:

BACKGROUND: Healthcare-associated infections (HAI) are among the leading causes of preventable death and are associated with significant financial costs. Treatment of HAI has been complicated by the rise of antimicrobial resistance (AMR). AMR limits the number of effective antibiotics available to treat HAI. Therefore, the prevention of these infections is increasingly important. Current evidence indicates that patients' colonization with multidrug-resistant organisms (MDRO) is a critical issue with the potential of causing serious harm. Fortunately, newer strategies such as copper usage in the healthcare environment are under development and these approaches may decrease the burden of MDRO without disrupting gastrointestinal colonization resistance. This project will explore a cutting-edge strategy to decrease HAIs through the reduction of environmental reservoirs by replacement of high-touch surfaces and textiles in an intensive care unit (ICU) setting using the inherent antimicrobial properties of copper alloys. By studying the incidence of MDRO colonization of patients and rates of HAIs in patients exposed and unexposed to copper-based surfaces and textiles, the aim is to expand knowledge, to help optimize the practice of the application of antimicrobial surfaces in the ICU setting. AIM: To establish the efficacy of the combined use of copper alloy-surfaced objects and copper-enriched textiles to reduce the burden of patients' MDRO colonization in the ICU. METHODS: The investigators will conduct a prospective, quasi-experimental study in the ICU at the Hospital Regional de Iquique. During the first stage of the study (6 months), the investigators will determine the cumulative incidence of MDRO acquisition (primary outcome) and the incidence rate of HAIs in patients admitted to the ICU before installation of the antimicrobial copper products. During the second stage (6 months), the investigator will assess study outcomes after the installation of copper surfaces over highly touched surfaces within the patient unit. EXPECTED RESULTS: It is expected a 30% reduction of the cumulative incidence of MDRO acquisition with respect to the control group. The investigators also expect this reduction to translate into a decrease of HAIs in the treatment versus the control group.
