Monitoring data feedback to cleaning staff through periodic audits can be a valid aid for improving cleaning and disinfection procedures and adherence to protocols. This strategy was adopted in our study and, thanks to the collaboration between the infection control team and the outsourced cleaning company, it was possible to identify the critical issues and take corrective actions. To this end, environmental monitoring is essential for process verification.

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 [

In the OT and ICU, where the limit for hygiene quality is defined by national guidelines, respectively, % (/) and % (/) of the surface samples resulted in being non-compliant after SOP. In the ward rooms, according to the standard reported in the literature, % (/) of the sampled sites resulted in being non-compliant. All of the samples were compliant after UV-C disinfection. In all of the settings, % (/) of the sampled points received a medium UV-C dose of mJ/cm

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. 

In that regard, the World Health Organization has reiterated the importance of using this type of disinfection after the adoption of the standard protocol for sanitizing hospital rooms, but, during the COVID- pandemic, the use of UVC radiation was also proposed immediately after the patient has been discharged in order to reduce the risk of the cleaning staff being infected, who can then safely apply the standard protocol [
