Abstract

The objective of this study was to use the fluorescent marker method to evaluate the effectiveness of an intervention aimed at improving environmental surface cleaning quality, while also investigating the correlation between cleaning staff’s awareness of protocols and the adequate provision of cleaning supplies (wipes and chemicals) at Thong Nhat Hospital. Subjects and Methods: A cross-sectional descriptive study with intervention was conducted on 446 high-touch surface locations at the Department of Internal Medicine (Service sector) and the Department of VIP (Senior Officials Treatment). Hygiene quality was assessed using the fluorescent marker method, comparing results before and after interventions that included staff retraining on knowledge and the supplementation of cleaning tools (wipes). Results: The proportion of completely cleaned surfaces increased significantly from 45.6% pre-intervention to 79.4% post-intervention. Post-intervention cleanliness rates across surface groups ranged from 63.8% to 89.2%, significantly higher than the pre-intervention range (22.8% - 62.3%). Additionally, the percentage of staff mastering the protocols rose from 68% to 82%, and the average number of wipes used per room increased from 2.42 to 3.63. Conclusion: The fluorescent marker method serves as an objective tool that reflects the actual quality of environmental hygiene more accurately than visual observation. The findings confirm the positive impact of knowledge training and the provision of adequate cleaning supplies in improving hospital surface cleaning quality.
