BACKGROUND
Hospital environment remains a risk for healthcare-associated infections (HAIs). This was a prospective study to evaluate the comprehensive impact of relocating a neonatal intensive care unit (NICU) to a new facility and improved environmental cleaning practice on the presence of methicillin-resistant Staphylococcus aureus (MRSA) on inanimate surfaces and the incident rate of HAIs.
METHODS
New environmental cleaning measures were adopted after the NICU was moved to a new and better-designed location. The effect of moving and the new environmental cleaning practice was investigated by comparing the positive number of MRSA on ward surfaces and the incidence density of HAIs between the baseline and intervention periods.
RESULTS
Only 2.5% of environmental surfaces were positive for MRSA in the intervention period compared to 44.0% in the baseline period (P<0.001). Likewise, the total incident rate of HAIs declined from 16.8 per 1000 cot-days to 10.0 per 1000 cot-days (P<0.001).
CONCLUSION
The comprehensive measures of relocating the NICU to a new facility design with improved environmental cleaning practice are effective and significantly reduce the incidence of HAIs.
背景
医院环境仍然是医源性感染（HAI）的风险因素。本研究旨在前瞻性评估将新生儿重症监护病房（NICU）转移到新的环境并改进环境清洁实践对不动表面耐甲氧西林金黄色葡萄球菌（MRSA）的存在以及 HAI 发生率的综合影响。
方法
NICU 搬迁到新的、设计更好的位置后，采用了新的环境清洁措施。通过比较基线期和干预期病房表面 MRSA 阳性数量和 HAI 发生率密度，研究了搬迁和新环境清洁实践的效果。
结果
干预期仅有 2.5%的环境表面 MRSA 阳性，而基线期为 44.0%（P<0.001）。同样，HAI 的总发生率从每千个婴儿床日 16.8 例下降到每千个婴儿床日 10.0 例（P<0.001）。
结论
将 NICU 搬迁到新的环境设计并改进环境清洁实践的综合措施是有效的，可显著降低 HAI 的发生率。
