Although the dose measurement system used in our study (FastCheck Mediland, Taoyuan City , Taiwan) is semi-quantitative, it allowed us to detect if the dose reached adequate values for disinfection and to repeat the application when the value was not satisfactory. However, each dose value exceeded the expected value. This demonstrates that the device was positioned correctly in order to avoid shadow areas, although it was necessary to properly place furniture and equipment to improve the irradiation of all surfaces. In the study conducted by Wong et al., the R-D Rapid Disinfector system (Steriliz, Rochester, NY, USA) was used in a tertiary care hospital to evaluate the incremental benefit of UV-C disinfection in isolation rooms after the discharge of infected patients. The employed robot used four detached sensors to directly measure the UV-C light [

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.

These organisms belong to a group of carbapenem-resistant, gram-negative bacteria of national and international concern because of their implication as an emerging cause of severe healthcare-associated infections. In , the World Health Organization published the first global guidelines for the prevention and control of CRE-CRAB-CRPsA in healthcare facilities, which include environmental cleaning and disinfection as a key recommendation.

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 settings where hospital cleaning services are assigned to private sector contractors, the use of new no-touch technologies could be considered in outsourcing contracts as an improvement action in the event of non-compliance in the cleaning service. The dedicated personnel should be adequately trained not only on the cleaning protocols to be adopted but also on infection control issues, underlining the key role of cleaning procedures.
