A systematic review and optimization prospect of infection control strategies for vascular access in blood purification centers
血液净化中心血管通路感染防控策略的系统综述与优化路径展望

摘要

血液净化治疗高度依赖血管通路，感染问题直接影响患者预后与医疗安全，临床现有多种感染防控措施，执行标准、风险识别与动态管理水平仍参差不齐，结合文献梳理血管通路感染危险因素、干预方式与管理模式，总结防控体系现存短板，含操作规范落实不到位、监测体系滞后、人员培训水平不一等问题。融合质量控制与循证实践思路，搭建风险分层、流程标准化、持续监测为核心的优化方案，突出信息化工具与多学科协作的支撑价值，推动感染管理由被动处置转向主动预防，提升血液净化中心整体感染管控能力。

Abstract

Blood purification therapy is highly dependent on vascular access. Infection directly affects patient prognosis and medical safety. While various infection control measures exist clinically, their implementation standards, risk identification, and dynamic management levels remain inconsistent. This paper reviews the risk factors, intervention methods, and management models for vascular access infections based on literature review, and summarizes existing shortcomings in the prevention and control system, including inadequate implementation of operational procedures, lagging monitoring systems, and inconsistent staff training levels. Integrating quality control and evidence-based practices, an optimization plan is developed centered on risk stratification, process standardization, and continuous monitoring. The supporting value of information technology tools and multidisciplinary collaboration is highlighted, promoting a shift in infection management from passive response to proactive prevention, and improving the overall infection control capabilities of blood purification centers.
