In our study, we evaluated the efficacy of the UV-C treatment only on the reduction in mesophilic growth that mainly represents human contamination, but not on specific pathogens of interest; however, the reduction was very significant, suggesting that this system can easily eliminate pathogens as well. We have previously demonstrated that the adoption of an automated UV-C-disinfection robot in the enhancement of SOP in high-risk settings was successful in reducing pathogens on high-touch surfaces, improving the patient&#x;s safety [

The cleaning procedure is not only dependent on the chemicals used but also on the personnel performing it. As reported by Toffollutti et al., there are differences between housekeeping and outsourcing cleaning staff in ensuring adequate levels of hygiene; outsourcing cleaning services was associated with a greater incidence of meticillin-resistant Staphylococcus aureus (MRSA) and worse patient perceptions of cleanliness [

Each hospital should have an infection control team aiming to evaluate the risk factors involved in healthcare infection occurrences with a multidisciplinary and dynamic approach. Epidemiological infection control in hospital may detect all of the critical points of the healthcare procedures performed by nurses, healthcare workers, physicians, students, and external staff. This evaluation may also include the sanitization process and its management. An appropriate evaluation of the whole sanitization process, including the reprocessing of cleaning materials, would be the best practice.

Among the appliable strategies for the improvement of cleaning and disinfection practices are the use of new materials and/or disinfectants, the training and audit of operators, and the use of new automated technologies, which are becoming increasingly important. In particular, no-touch disinfection technologies have the great advantage of not being dependent on the operator, ensuring process repeatability. Furthermore, their effectiveness has been demonstrated even on sites that are difficult to reach with manual intervention. Their use complements but does not replace ordinary cleaning and disinfection protocols. In the past few years, ultraviolet disinfection systems have been widely investigated and used as a way to improve standard cleaning protocols. Currently, ultraviolet devices are automated in order to guarantee process repeatability and reduce human errors. The application of UV devices as an addition to traditional environmental cleaning has become increasingly common due to their effectiveness in reducing the environmental microbial burden in a shorter time compared to other technologies using chemical products [

We are more than just a water pump company. Through our solutions and services, we touch millions and millions of people every day, without most even noticing. And with that comes great responsibility. A responsibility to respect, protect and advance the flow of water for people, businesses and the planet. Because at Grundfos, we believe that every drop contains infinite possibilities, and that water has the power to change the world.
