Data concerning the effectiveness of strategies implemented to reduce short peripheral vein catheter (PVC)-related adverse events are scarce.
A quasiexperimental study (2004-2011) was conducted to evaluate an intervention to reduce peripheral vein phlebitis (PVP) and PVC-related bloodstream infections (BSIs). Bundle intervention consisted of health care worker education and training, withdrawal of unnecessary catheters, exchange catheter policy, withdrawal of catheters at early stages of PVP, use of scales as a measuring tool, and repeated period-prevalence surveillance of PVC adverse events on wards. A Poisson exponentially weighted moving average control chart was used to assess time series analysis.
One thousand six hundred thirty-one patients with 2,325 short catheters inserted were prospectively followed. PVP decreased by 48% (12.1% [95% confidence interval (CI): 10.7-13.2] during the intervention period versus 23.3% [95% CI: 16.4-30.1] in preintervention period; P < .05), and no reduction of PVP measured as 1,000 catheter-days was noted (48.6 [95% CI: 46.1-51.2] vs 37.9 [95% CI: 24.5-51.4], P > .05). A significant incidence reduction in PVC-related BSIs and health care-acquired Staphylococcus aureus BSIs was also achieved.
A comprehensive multifaceted hospital approach was successful in reducing PVC-related adverse effects. Poisson exponentially weighted moving average control chart fits well as time series using Poisson data when very few events are present.
有关减少外周短导管(PVC)相关不良事件的策略有效性的数据很少。
进行了一项准实验研究(2004-2011 年),以评估一项旨在减少外周静脉炎(PVP)和 PVC 相关血流感染(BSI)的干预措施。捆绑干预措施包括医护人员教育和培训、取消不必要的导管、更换导管政策、在 PVP 早期阶段拔除导管、使用量表作为测量工具,以及对病房 PVC 不良事件进行反复的时期患病率监测。使用泊松指数加权移动平均控制图进行时间序列分析。
前瞻性随访了 1631 名接受 2325 个短导管插入的患者。PVP 下降了 48%(干预期间为 12.1%[95%置信区间(CI):10.7-13.2],而干预前为 23.3%[95%CI:16.4-30.1];P<0.05),并且 1000 个导管日的 PVP 测量值没有降低(48.6[95%CI:46.1-51.2] vs 37.9[95%CI:24.5-51.4],P>0.05)。还显著降低了 PVC 相关 BSIs 和医源性金黄色葡萄球菌 BSIs 的发生率。
一种全面的多方面医院方法成功地减少了 PVC 相关的不良影响。泊松指数加权移动平均控制图非常适合使用泊松数据进行时间序列分析,当存在很少的事件时。
