主要方法:

从2017年到2023年,对现有NICU中的医院病房集群事件进行回顾性分析.
使用临床查,全基因组测序和核心基因组多部位序列类型 (cgMLST) 识别和确认格拉姆阴性细菌群.
评估水槽排水作为细菌传播的潜在来源的作用.

主要成果:

在2017年至2023年期间,新生儿重症监护室记录了9起涉及细菌病原体的医院病房集群事件.
包括Klebsiella oxytoca*,Pseudomonas aeruginosa*和Enterobacter hormaechei*在内的三种格拉姆阴性细菌集群可能与水槽排水有关.
全基因组测序和cgMLST证实了这些细菌集群中的克隆关系.

结论:

在NICU中实施水槽排水可能会对患者的安全产生负面影响,因为潜在的细菌储存库.
建议在设计或重新设计敏感区域 (如NICU) 时避免在病房内使用洗手盆.
这项研究强调了基础设施设计在预防脆弱患者群体中与医疗保健相关的感染方面的重要性.

Healthcare Associated Infections II: Preventive Measures

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.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Urinary Tract Infection IV: Nursing Management

Urinary Tract Infection IV: Nursing Management

In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs...
