概括

与外围插入的中央导管 (PICC) 相关的多药耐药生物体 (MDROs) 引起的中央线路相关血流感染 (CLABSI) 发生的停留时间更短. 这凸显了在评估PICC感染风险的停留时间时需要考虑MDROs的必要性.

科学领域:

传染性疾病传染性疾病
医疗器械医疗器械
流行病学流行病学

背景情况:

关于外围插入的中央导管 (PICC) 停留时间与中心线相关血流感染 (CLABSI) 或导管殖民等结果之间的关系,存在知识差距.
多抗药微生物 (MDROs) 在医疗保健环境中构成重大威胁,了解它们与医疗器械的关联至关重要.

研究的目的:

为了比较由MDROs引起的CLABSIs的患者中PICC的停留时间,与MDROs引起的导管殖民患者相比.
调查PICC停留时间与CLABSI或MDROs殖民的发生之间的联系.

主要方法:

追溯分析了2017年至2020年期间入院于三级医院的86名患者的数据.
不同组之间的PICC平均停留时间的比较:PICC-CLABSI与PICC-colonization,以及PICC-MDRO与PICC-non-MDRO.
基于MDRO状态的PICC-CLABSI和PICC-colonization组内的子组分析.

主要成果:

平均停留时间在PICC-CLABSI组 (25.73天) 与PICC-殖民组 (16.36天) 相比,PICC-CLABSI组的平均停留时间明显长 (p=0.002).
与PICC-non-MDRO组 (22.48天) 相比,PICC-MDRO组的平均停留时间更短 (17.38天) (p=0.005).
在CLABSI中,MDRO引起的感染的平均停留时间比非MDRO (27.73天) 短 (21.50天),尽管在统计学上并不显著 (p=0.417). 基于MDRO状态,殖民PICC的停留时间没有显著差异.

结论:

与PICC相关的MDROs引起的CLABSI可能与非MDROs相比,平均导管停留时间较短.
这些发现强调了在评估PICC停留时间时在感染风险的背景下考虑MDRO的重要性.
需要进一步的研究来阐明PICC停留时间,MDROs和感染结果之间的复杂相互作用.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

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.

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...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
