概括
网络分析确定了在重症监护室 (ICU) 传播医院相关感染 (HAI) 的高风险项目 (HRIs). 这些HRI显示细菌污染明显高于低风险物品,指导了针对性的消毒策略.
科学领域:
- 感染控制 感染控制
- 医院流行病学 医院流行病学
- 微生物学 微生物学
背景情况:
- 与医院相关的感染 (HAI) 在重症监护室 (ICU) 构成重大威胁.
- 福米特传播是HAI的关键途径,需要识别高风险物品 (HRIs).
- 目前的战略往往侧重于高接触物品 (HTIs),但它们在污染中的作用需要进一步调查.
研究的目的:
- 为了确定参与HAI在ICU环境中传播HAI的HRIs.
- 在已识别的HRIs上量化细菌污染水平.
- 为了比较HRIs,HTIs和低接触物品之间的污染水平.
主要方法:
- 在13个床位的ICU中进行了为期15天的手对地接触观察.
- 利用定向加权网络,根据中心性分析识别HRIs.
- 在四天内,在多个时间点从各种表面收集了有氧细菌样本.
主要成果:
- 确定了高风险物品 (HRIs),尽管并不总是与高触摸物品 (HTIs) 重叠.
- 在HRIs上的细菌污染水平明显高于低风险物品.
- 在HTIs和低接触物品之间,没有发现细菌污染的显著差异.
结论:
- 网络分析有效地识别了针对ICU的清洁和消毒的HRIs.
- 仅仅依靠高触摸物品可能不足以有效控制感染.

Standard Precaution
3.3K
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...

Transmission-based Precautions II: Airborne and Protective Environment
2.1K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

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.

Hand hygiene
6.4K
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.

Cleaning, Sterilization, and Disinfection
12.3K
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
