2006～2014年某院医院感染现患率调查结果

目的分析某院连续5次医院感染现患率调查结果的变化趋势。方法选取2006、2008、2010、2012和2014年某日现患率进行分析。结果 5次调查现患率1.62%~4.44%,例次现患率1.96%~4.73%。现患率较高的科室为各重症监护病房（ICU）,感染部位以呼吸道为主（48.44%~66.13%）。Ⅰ类切口外科围手术期抗菌药物使用率为由93.50%下降至65.50%（P〈0.01）。结论该院近年医院感染现患率无明显变化,抗菌药物临床应用合理性明显改进。

Objective To investigate the changing trends in 5 continuous point prevalence rate of healthcare-assoeiated infection （HIA） in a hospital. Methods To analysis the prevalence rate on a given day in 2006, 2008, 2010, 2012 and 2014 respectively. Results The point prevalence rate was 1.62% to 4.44%, the case prevalence rate was 1.96% to 4.73%. The intensive care unit （ICU） had higher prevalence rate. The infective site was more common in respiratory tract （48.44%-66.13%）.There was no big difference in prevalence rate, department distribution and infection site among these surveys. The perioperative antimicrobial drug utilization rate of type I incision surgery decreased gradually from 93.50% to 65.50% （P〈0.01）. Conclusion The prevalence rate has no obvious change in this hospital in recent years, the rationality of clinical application of antibacterial drugs significantly improved.
