Application of targeted nursing intervention in prevention and control of catheter-associated blood stream infection in patients undergoing intravenous therapy
针对性护理干预在静疗患者导管相关血流感染防控中的应用研究

摘要

目的 探究基于风险分级的针对性护理干预在静疗患者导管相关血流感染（CRBSI）防控中的应用效果。方法 选取2025年7-12月接受静脉治疗并留置中心静脉导管的80例患者为研究对象，随机分为对照组与实验组，各40例。对照组实施常规静疗护理，实验组采用针对性护理干预。结果 实验组CRBSI发生率（2.5%）显著低于对照组（17.5%）（χ2=4.507，P=0.034），导管留置时间长于对照组（t=5.218，P＜0.001），患者护理满意度（97.5%）高于对照组（82.5%）（χ2=4.500，P=0.034），差异均有统计学意义。结论 针对性护理干预可有效降低静疗患者CRBSI发生率，延长导管留置时间，提升护理满意度，临床应用价值显著，值得推广。

Abstract

Objective To investigate the application effect of targeted nursing intervention based on risk stratification in the prevention and control of catheter-related bloodstream infection(CRBSI)in patients receiving intravenous therapy.
Methods A total of 80 patients who underwent intravenous therapy and had central venous catheterization from July to December 2025 were selected as the study subjects and randomly divided into a control group and an experimental group, with 40 cases in each group. The control group received routine intravenous therapy nursing, while the experimental group received targeted nursing intervention.
Results The incidence of CRBSI in the experimental group (2.5%) was significantly lower than that in the control group (17.5%) (χ2=4.507, P=0.034). The duration of catheter placement was longer in the experimental group than in the control group (t=5.218, P<0.001), and patient nursing satisfaction (97.5%) was higher in the experimental group than in the control group (82.5%) (χ2=4.500, P=0.034). All differences were statistically significant.
Conclusion   Targeted nursing intervention can effectively reduce the incidence of CRBSI in patients receiving intravenous therapy, prolong the duration of catheter placement, and improve nursing satisfaction. It has significant clinical application value and is worthy of promotion.
