【摘要】 目的探讨集束干预策略预防中心静脉导管相关性血流感染(catheter related blood stream infection,CRBSI)的效果。方法将实施集束干预策略之前(2011年1～10月)留置中心静脉导管186例患者设为对照组,在实施集束干预策略之后(2012年1～10月)留置中心静脉导管193例患者设为集束组。比较实施集束干预措施前后两组患者CRBSI发生率及时间,置管情况。结果采用集束干预策略后CRBSI发生率由实施前8.31‰下降至1.67‰,前后比较,差异具有统计学意义(P<0.001);CRBSI发生时间由(7.47±2.44)d延长至(13.75±1.92)d,前后比较,差异具有统计学意义(P<0.05);锁骨下静脉置管率从39.78%上升至71.50%,股静脉置管率从45.70%下降至18.65%,前后比较,差异具有统计学意义(均P<0.05)。结论集束干预策略可有效降低中心静脉置管患者CRBSI发生率。更多还原

【Abstract】 Objective To study the preventive effect of cluster intervention strategies for central venous catheter(CVC) on catheter-related bloodstream infection.Methods One hundred and eighty six patients with CVC during Jan.to Oct.2011 before application of cluster intervention strategies were assigned in the control group and another 193 with CVC during Jan.to Oct.2012 after using cluster intervention strategies in the cluster group.The two groups were compared in terms of the incidence and time of CRBSI as well as the catheteration.Results After using the cluster intervention strategies,the incidence of CRBSI was decreased from 8.31‰ to 1.67‰(P < 0.001).The time of CRBSI was prolonged from(7.47±2.44) to(13.75±1.92)d(P < 0.05).The catheteration in subclavian vein was significantly increased from 39.78% to 71.50%(P < 0.05) and the catheteration was significantly deceased from 45.70% to 18.65%(P < 0.05).Conclusion The CVC cluster intervention strategies may effectively reduce the incidence of CRBSI.更多还原
