Métodos de desinfecção "no-touch": Revisão sobre o uso de dispositivos baseados na emissão de luz UV-C e vapor de peróxido de hidrogênio

Abstract

Contamination of hospital surfaces directly involves pathogen spreads, suggesting that standard disinfection and cleaning procedures are insufficient. So, there is an increasing demand for new safe, effective, and rapid methods to aid in the terminal disinfection of environmental surfaces in Health Care Establishments. Within these optics, the “no-touch” devices aim to improve the levels of terminal disinfection. Among the wide variety of devices available in the market, stand out the methods of hydrogen peroxide vapor generation and based on emission of ultraviolet radiation. This paper proposes to review and characterize the main “no-touch” technologies. In addition, to gather its primary advantages and disadvantages, and to seek studies in the literature evaluating the effectiveness in reduction of multiresistant pathogens and the impact of their implementation on the rates of infections related to health care. For this study, it conducted a survey in two databases, using keywords and boolean operators to improve the search strategy. Two phases are used to select 22 studies based on pre-defined inclusion and exclusion criteria. Automated disinfection systems can offer a reduction of the residual contamination added to manual cleaning. The results suggest that the hydrogen peroxide vapor device has greater power of pathogen reduction compared to the ultraviolet light device, but it has longer cycle times and configuration and is difficult to use. Throughout, the study designs presents heterogeneity in the methods and results. Thus, the methods have compensation for time and efficiency. The initial acquisition costs are considerable and higher for devices based on the emission of ultraviolet light, however hydrogen peroxide vapor devices have higher continuous costs. Finally, on the clinical impact, conclude that there is not enough evidence to compare the devices, and that there is an urgent demand for standardized regulation and testing for “no-touch” disinfection devices.
