Abstract

Healthcare-associated infections (HAIs) caused by Pseudomonas aeruginosa remain a significant concern in hospital environments, due to the pathogen’s resistance to antibiotics and its ability to form persistent biofilms on surfaces. Advanced disinfection technologies, like ultraviolet-C (UV-C) light and pulsed xenon UV (PX-UV), have shown potential as solutions to these challenges. This study performed a descriptive analysis of five selected studies evaluating how effective these methods are in reducing P. aeruginosa contamination on hospital surfaces. The studies, conducted in China, United States, and Brazil, focused on UV-C and PX-UV disinfection methods in varied healthcare settings, with sample sizes ranging from 7 to 203 surfaces. The average reduction in colony-forming units (CFUs) was 83.4%, with individual study results ranging from 44% to 100%. UV-C showed consistent efficacy (75-99%) across different settings, while PX-UV demonstrated greater variability (44-100%). The findings underline the need to integrate advanced disinfection methods with manual cleaning protocols to improve outcomes. This analysis highlights the importance of optimizing disinfection practices and tailoring them to healthcare settings for effective infection preventions.
