概括
较低的白蛋白水平和抗生素或葡萄糖皮质激素的使用增加了在被殖民患者中耐卡巴因耐药的Acinetobacter baumannii (CRAB) 感染的风险. 抗真菌药物和中央静脉导管与CRAB感染患者的死亡率有关.
科学领域:
- 传染性疾病 传染性疾病
- 关键护理医学 关键护理医学
- 医院流行病学 医院流行病学
背景情况:
- 耐卡巴胺的宝曼菌 (Acinetobacter baumannii,简称CRAB) 作为一种机会性病原体,构成重大威胁,导致殖民和医院感染.
- 了解从CRAB殖民到活跃感染的过渡对于有效的患者管理和感染控制至关重要.
研究的目的:
- 在一般医院病房中,确定与从呼吸道殖民到感染的进展相关的独立风险因素,用于在一般医院病房中殖民于CRAB的患者.
- 分析导致CRAB感染患者28天死亡的因素,这些患者最初出现了殖民.
主要方法:
- 从2021年1月到2023年12月,在一般病房中进行了一项回顾性研究,涉及202名患有CRAB的患者.
- 使用单变量和多变量后勤回归模型来确定与从殖民到感染以及随后死亡率的进展相关的因素.
主要成果:
- 在202名CRAB殖民患者中,66人进展为感染,36人经历了28天的死亡率. 随后感染的患者死亡率较高 (27.27%对13.24%).
- 感染进展的独立风险因素包括较低的白蛋白 (ALB) 水平 (OR=0.94),抗生素使用 (OR=2.49),和葡萄皮质激素使用 (OR=2.49).
- 对于在殖民后患有CRAB感染的患者,抗真菌药物使用 (OR=18.06) 和中央静脉导管存在 (OR=10.73) 与28天死亡率有显著关联.
结论:
- 较低的ALB水平和抗生素或葡萄糖皮质体的使用被确定为在通用医学病房内的殖民患者中发展CRAB感染的关键风险因素.
- 在CRAB感染患者中,抗真菌剂的使用和中央静脉导管的存在是与28天死亡率增加相关的关键因素.
- 这些发现强调了需要有针对性的预防策略和优化的治疗指南,以减轻CRAB感染对住院患者的影响.

01:26Factors Affecting the Risk of Infection
13.3K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

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.

01:30Pneumonia I: Introduction
731
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

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...

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...
