摘　　要：目的根据医院7年来连续进行现患率调查的结果,分析近7年来医院感染控制措施执行效果,为感染控制提供依据。方法采取床旁调查和住院病历查询相结合的方式通过对2012-2018年四川大学华西医院每年6月下旬某天0-24时住院患者进行医院感染现患率调查,并由医院感染管理部专职人员进行数据核对、汇总和统计分析。结果2012-2018年医院感染现患率分别为5.23%、4.20%、3.94%、4.26%、4.29%、4.23%、2.97%,呈下降趋势(卡方趋势检验χ^2=32.826,P<0.001),现患例次率分别为5.81%、4.58%、4.24%、4.73%、4.55%、4.48%、3.21%,呈下降趋势。2012-2018年泌尿道医院感染现患率分别为0.39%、0.31%、0.29%、0.40%、0.32%、0.31%、0.30%,差异无统计学意义,(趋势卡方检验χ^2=0.342,P=0.558);导尿管相关尿路感染(Catheterassiciated urinary tract infection,CAUTI)现患率分别为0.14%、0.18%、0.21%、0.28%、0.17%、0.23%、0.24%;差异无统计学意义(趋势卡方检验χ^2=0.346,P=0.558),非CAUTI现患率分别为0.25%、0.13%、0.08%、0.12%、0.15%、0.07%、0.06%,现患率呈下降趋势(卡方趋势检验χ^2=4.84,P=0.028)。2012-2018年7年的CAUTI病原体总数中构成比最高的是大肠埃希菌,占48.65%。结论2012-2018年医院感染现患率呈下降趋势,但泌尿道的感染率无变化,非CAUTI呈下降趋势,而CAUTI差异无统计学意义,需引起足够重视,同时也应根据调查结果增强CAUTI的目标性监测,采取有效干预措施,降低CAUTI感染率。OBJECTIVE To analyze the implementation effect of the nosocomial infection control measures according to the investigation of the prevalence rate in the hospital in the past seven years,in order to provide a basis for the infection control.METHODS By means of both bedside investigation and case history taking,investigation was made on the prevalence rate of the nosocomial infection in patients who were admitted to the West China Hospital of Sichuan University during 00:00 a.m.to 24:00 p.m.on one day in late June from 2012 to 2018.Data were checked,collected and analyzed statistically by the staff in the Infection Management Department of the Hospital.RESULTS From 2012 to 2018,the prevalence rates of the nosocomial infection were 5.23%,4.20%,3.94%,4.26%,4.29%,4.23%,and 2.97%,respectively,which showed a downward trend(χ^2=32.826,P<0.001);the case prevalence rates were 5.81%,4.58%,4.24%,4.73%,4.55%,4.48%,and 3.21%,respectively,showing a downward trend.From 2012 to 2018,the prevalence rate of the nosocomial urinary tract infection was 0.39%,0.31%,0.29%,0.40%,0.32%,0.31%,and 0.30%,respectively,and the difference between them was not significant(χ^2=0.342,P=0.558);the prevalence rates of the catheter-associated urinary tract infection(CAUTI)were 0.14%,0.18%,0.21%,0.28%,0.17%,0.23%,and 0.24%,respectively,and the difference was not significant(χ^2=0.346,P=0.558);the prevalence rates of the non-CAUTI were 0.25%,0.13%,0.08%,0.12%,0.15%,0.07%,and 0.06%,respectively,showing a downward trend(χ^2=4.84,P=0.028).From 2012 to 2018,the constituent ratio of Escherichia coli among CAUTI-associated pathogens was the highest(48.65%).CONCLUSION From 2012 to 2018,the prevalence rate of the nosocomial infection showed a downward trend;however,the urinary tract infection rate remained constant.The non-CAUTI rate showed a downward trend,and the differences in CAUTI were not significant along with time.More attention should be paid to this problem.Also,according to the investigation results,targeted monitoring of CAUTI should be enhance
