ABSTRACT
BACKGROUND:
The hospital environment is an important source of multidrug-resistant organisms such as methicillin-resistant Staphylococcus aureus (MRSA). Here, we evaluated the efficacy of pulsed xenon ultraviolet (PX-UV) disinfection in addition to manual cleaning in a Japanese hospital.METHODS:
Environmental samples were collected from inpatient rooms that had been occupied for at least 48 hours by patients infected or colonized with MRSA. High-touch surfaces from 11 rooms were sampled before and after manual cleaning and then after PX-UV disinfection. Changes in bacterial counts and in the number of aerobic bacteria (AB)- and MRSA-positive samples between sampling points were assessed. The time taken to complete PX-UV treatment of patient rooms was also recorded.RESULTS:
A total of 306 samples were collected. PX-UV disinfection resulted in a significant decrease in abundance of AB and MRSA (mean colony-forming units 14.4 ± 38.7 to 1.7 ± 6.1, P < .001 and 1.1 ± 3.9 to 0.3 ± 2.0, P < .001, respectively) and in the number of AB- and MRSA-positive samples (58.8%-28.4%, Pâ¯=â¯.001 and 19.6%-3.9%, P < .001, respectively) compared with manual cleaning. The median time of in-room use of the PX-UV device was 20 minutes.CONCLUSIONS:
The addition of PX-UV disinfection to the manual cleaning process significantly reduced AB and MRSA contamination of high-touch surfaces in hospital inpatient rooms.Palabras clave
