概括
结合感染控制措施,如接触预防措施和赫西丁浴,可显著减少多抗药生物体的获取. 调整干预措施以适应特定环境和耐药性概况,优化医疗保健资源效率.
科学领域:
- 传染性疾病 传染性疾病
- 医疗流行病学 医疗流行病学
- 公共卫生 公共卫生
背景情况:
- 在医疗保健环境中,针对多种耐药生物体 (MDROs) 的感染预防和控制 (IPC) 措施的有效性受到争论.
- 标准预防措施 (SP) 是基础,但它们在控制MDRO方面的局限性需要探索增强策略.
研究的目的:
- 系统地评估各种IPC干预措施对抗MDROs在医疗保健环境中的比较有效性.
- 确定最佳的干预组合,以减少MDRO的获取,感染和殖民.
主要方法:
- 在主要数据库 (PubMed,Embase,MEDLINE,Cochrane图书馆,CINAHL) 进行了全面的文献搜索,截至2024年6月1日.
- 包括的研究评估了干预措施,如标准预防措施 (SP),接触预防措施 (CP),手部卫生 (HH),环境清洁 (ENV),抗菌管理计划 (ASP),非殖民化 (DCL) 和素浴 (CHG).
- 主要结局是MDRO获取,感染和殖民,使用率比率 (RRs) 和95%置信区间 (CI) 进行分析.
主要成果:
- 分析了97篇文章 (19个RCT,78个非RCT). 减少MDRO获取,感染和殖民的最有效组合各不相同.
- 特定组合,如接触预防措施+素浴 (CP+CHG) 和标准预防措施+接触预防措施+环境清洁 (SP+CP+ENV) 显示显著减少.
- 在重症监护室 (ICU) 中,CP+CHG对获取最有效,而SP+CP+ENV对感染最有效. 在全医院范围内,SP+CP+ENV+CHG对殖民非常有效.
结论:
- 有效的MDRO控制策略取决于上下文,根据患者携带状态,医疗保健环境 (例如,ICU与全医院) 和特定的耐药菌株而有所不同.
- 接触预防措施是组合干预的关键组成部分.
- 医疗机构应根据当地抵抗模式战略性地选择干预措施,以提高精度和资源利用率.

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.
