The impact of environmental cleaning protocol featuring PX-UV in reducing the incidence of multidrug-resistant gram-negative healthcare-associated infection and colonization in intensive care units in Thailand.

In this quasi-experimental study, implementing PX-UV to the standard environmental cleaning protocol was associated with a reduction in the overall incidence of multidrug-resistant (MDR) gram-negative organisms ( P = .01) and MDR Acinetobacter baumannii ( P = .001) in intervention intensive care units. However, the intervention did not reduce patient length of stay and 30-day mortality.
