摘要
背景：受污染的环境表面在病原体传播过程中扮演着重要角色，而病原体传播会导致医源性感染（HAI）。本研究旨在评估与埃及亚历山大主大学医院神经外科重症监护室（ICU）的常规清洁相比，加强清洁技术对高接触区域细菌污染的影响：方法：通过问卷调查和观察清单对医护清洁人员和护士的知识和实践进行评估。在重症监护病房的一个房间内为医护清洁人员和护士开展了关于加强清洁的教育活动。在重症监护病房的两个房间（A 房间和 B 房间）分别采集了清洁前后的环境表面拭子。选择 A 房间进行强化清洁，选择 B 房间进行常规清洁：结果：与常规清洁相比，强化清洁后病人周围高接触区域的细菌数量明显减少（p 结论：强化清洁对病人周围高接触区域的细菌数量减少效果明显：临床试验注册号：PACTR202402531：临床试验注册号：PACTR202402531001186，日期：2024 年 2 月 15 日，"回顾性注册"。
The impact of enhanced cleaning on bacterial contamination of the hospital environmental surfaces: a clinical trial in critical care unit in an Egyptian hospital.
Background: Contaminated environmental surfaces play an important role in the transmission of pathogens that cause healthcare acquired infection (HAI). The present study aimed to assess the effect of enhanced cleaning techniques on bacterial contamination in high-touch areas compared to routine cleaning at the intensive care units (ICU) of the neurosurgery department of Alexandria Main University Hospital, Egypt.
Methods: The assessment of the knowledge and practices of healthcare cleaning workers and nurses was conducted through a questionnaire and an observational checklist. An educational program about enhanced cleaning was carried out for healthcare cleaning workers and nurses in one room of the ICU unit. Environmental surface swabs were taken from the two rooms of the ICU before and after cleaning (room A and room B). Room A was selected to apply the enhanced cleaning, and room B was selected for routine cleaning.
Results: A significant decrease in bacterial counts in the high-touch areas around the patients after the application of enhanced cleaning compared to routine cleaning (p < 0.001) was observed. Gram-negative bacteria isolated from high-touch areas accounted for 45.6% of the samples collected before enhanced cleaning, and they became 16.3% after enhanced cleaning (p < 0.001), while they accounted for 40% after routine cleaning. The enhanced cleaning intervention in Room A resulted in a significant reduction in total infections, decreasing from 18 cases in the six months prior to the intervention to 11 cases in the six months following its implementation. (p < 0.05).
Conclusion: The effect of enhanced cleaning was evident in decreasing bacterial counts in the high-touch areas around the patient and consequently in the records of the HAI rate inside the ICU.
