Abstract: Backgrounds: To increase knowledge and awareness of environmental cleanliness of staff responsible for hospital cleaning through an enhanced infection control programme, which should in turn reduce the risk of health-care associated infection due to ineffective environmental cleanliness. Methods: This study applied a single group, pretest posttest design. The subjects were supporting staff that was responsible for the environmental cleaning recruited from an infectious disease unit. Total 10 teaching sessions in two weeks of en enhanced training programme related to environmental cleanliness was provided to the supporting staff of the infectious disease unit in August, 2011. A questionnaire was used to measure the knowledge in relation to environmental cleanliness among the supporting staff before and after the enhanced training programme. In addition, the environmental samples on the 11 targets sites (high touch areas) by using the ATP bioluminescence method, the microbiologic bacterial count and invisible fluorescence marking were collected from four isolation rooms in the infectious disease unit after the occupancies were discharged in pre-intervention, post-intervention and post-intervention one month follow up (one month FU). The target sites were included touch screen of bedside cardiovascular monitor, call button, telephone handset, suction port regulator, patient locker, bedside rail, bed table, handle of specimen transfer hub, toilet door handle, toilet flushing button and toilet seat. The results from three assessment tools in pre-intervention, post-intervention and one month FU were compared to the effectiveness, if any, of the enhanced training programme related to environmental cleanliness. Results: There was significant improvement in the level of knowledge (p-value < 0.05) following the enhanced training programme. In addition, the results by ATP Bioluminescence, microbiologic bacterial count, and invisible fluorescence marking from the 11 target sites before and after cleaning were compared in pre-intervention, post-intervention, and at one month FU. These were significantly reduced in post-intervention and one month FU compared with pre-intervention at p < 0.05. Conclusions: The results demonstrated significant improvement in supporting staff knowledge of environmental cleanliness. There was significant reduction in ATP Bioluminescence, microbiologic bacterial count, and percentage of invisible fluorescence marking removed in target sites. A tailor made enhanced training programme related to environmental cleanliness may therefore improve the effectiveness of the environmental cleaning and reduce the risk of healthcare-associated infection.
