Abstract

Background

Central venous catheters (CVCs) pose a risk of infection through fluid infusion, medication administration, and blood draws. We conducted a scoping review evaluating the risk of accessing a CVC and aiming to identify strategies for limiting CVC usage to decrease the incidence of central line-associated bloodstream infections (CLABSIs) in hospital settings.

Methods

This review adheres to the methodological framework proposed by Arksey and O’Malley and is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. Searches were conducted in the CINAHL, EMBASE, PubMed, and Scopus databases, focusing on publications from the past decade.

Results

Six studies met inclusion criteria. Three interventions were identified: (1) establishing standardized CVC sampling times, (2) utilizing phlebotomists to perform peripheral blood cultures, and (3) avoiding the use of CVCs for both blood cultures and routine blood draws.

Conclusions

Increased frequency of CVC access is associated with a higher risk of CLABSI. Interventions to reduce CVC access for blood draws can effectively lower CLABSI rates. Identifying and implementing strategies such as use of phlebotomy teams and standardized sampling protocols may help guide hospital policies and improve patient safety outcomes. Future research should focus on prospective evaluation of these approaches.

限制中心静脉导管进入血液采样及其对中心静脉相关血流感染的影响：范围综述。

背景：中心静脉导管（CVCs）固有地通过输注液体、给药和抽血造成感染风险。我们进行了一项范围综述，评估使用CVC的风险，旨在确定减少或限制CVC使用的策略和干预措施，以降低医院环境中中心线相关血流感染（CLABSIs）的发生率。方法：本综述遵循Arksey和O'Malley提出的方法框架，并按照系统评价和荟萃分析扩展范围评价（PRISMA-ScR）指南的首选报告项目进行报道。在CINAHL、EMBASE、PubMed和Scopus数据库中进行了搜索，重点是过去十年的出版物。结果：6项研究符合纳入标准。一项研究报告，每增加一次CVC接入，CLABSI的每日风险增加0.7%。四项研究表明，限制从cvc抽血与CLABSI发生率的降低有关，包括标准化感染率的改善和血液感染计数的减少。确定了三种主要干预措施：(1)建立标准化的CVC采样时间，(2)利用抽血师进行外周血培养，(3)避免在血液培养和常规抽血中同时使用CVC。结论：CVC通路频率增加与CLABSI的高风险相关。减少CVC抽血机会的干预措施可有效降低CLABSI发生率。确定和实施诸如使用静脉切开术小组和标准化抽样协议等战略可能有助于指导医院政策并改善患者安全结果。未来的研究应侧重于对这些方法的前瞻性评价。”
