目的了解2011年医院感染发生的状况及抗菌药物的使用,为医院感染监测和预防控制提供依据。方法采用横断面调查的方法,对10月12日0∶00-24∶00住院的患者进行调查,以统一的标准填写调查表并进行统计分析。结果实查2350例,发生医院感染141例、158例次,现患率6.00%、例次感染率6.72%;感染部位以下呼吸道感染居首位,占45.73%,其次为血液、上呼吸道,分别占12.20%、10.98%;共分离出86株病原体,居前3位的为铜绿假单胞菌、不动杆菌属、克雷伯菌属,分别占20.93%、18.60%和12.79%;抗菌药物使用率为32.09%,治疗性用药时病原学送检率为48.20%。结论通过对医院感染现患率的调查,将加强对医院感染高发科室的监控,强化抗菌药物的合理使用,从而降低医院感染的发生。
Objective To understand the occurrence of nosocomial infections in 2011 and the use of antimicrobial agents to provide evidence for monitoring and preventing nosocomial infections. Methods The method of cross-sectional survey was used to investigate the patients hospitalized at 0: 00-24: 00 on October 12, and the questionnaires were filled in with uniform standards and analyzed statistically. The results of real investigation of 2350 cases, nosocomial infection in 141 cases, 158 cases, the prevalence rate of 6.00%, the infection rate of 6.72%; infection below the site of respiratory tract infection ranked first, accounting for 45.73%, followed by blood, upper respiratory tract, respectively 12.20%, and 10.98% respectively. Totally 86 pathogens were isolated, among which Pseudomonas aeruginosa, Acinetobacter and Klebsiella were the top 3 pathogens, accounting for 20.93%, 18.60% and 12.79% respectively. Antibacterials The rate was 32.09%. The etiology of the therapeutic drug was 48.20%. Conclusion The survey of prevalence of nosocomial infections will strengthen the monitoring of high incidence of nosocomial infections and strengthen the rational use of antimicrobial agents to reduce the incidence of nosocomial infections.
