摘　　要：目的了解某医院住院患者医院感染基本情况,为有效预防医院感染发生提供科学依据。方法采用横断面调查方法,对某教学医院的住院患者进行医院感染现患率调查。结果实查当日住院患者4 249例,查出医院感染患者118例、125例次,医院感染现患率为2.78%、例次感染率为2.94%。医院感染患者主要分布于重症监护病房;感染部位以下呼吸道居首位,占50.40%。调查当日抗菌药物使用率为45.35%,抗菌药物使用前病原菌送检率为29.10%。检出病原菌中以革兰阴性菌为主,构成比为71.11%,真菌感染居其次,革兰阳性菌检出率居第三位。结论该医院住院患者医院感染率处于可控状态,主要感染病原菌为革兰阴性菌,应提高病原菌标本送检率。Objective To understand the fundamental status of nosocomial infections in hospitalized patients,and to provide scientific basis for prevention of nosocomial infections. Methods Cross- sectional survey was conducted to investigate the prevalence rate of nosocomial infections on hospitalized patients in a teaching hospital. Results 4 249 patients were actually investigated with 118 cases and 125 case- time nosocomial infected patients found out. The prevalence rate and case- time prevalence rate of nosocomial infections were 2. 78% and 2. 94%,respectively. The nosocomial infected patients were mainly distributed in general ICU,and the lower respiratory tract ranked the first place among the infection sites,accounting for 50. 40%. The daily utilization rate of antibiotics was 45. 35%. The submission rate of etiology before using antimicrobial drugs was 29. 10%. Gram- negative bacteria were major pathogens of nosocomial infections,accounting for71. 11%,and fungal infections ranked second,gram- positive bacteria was the third. Conclusion The Prevalence rate of nosocomial infections in the hospital was in the control. The major pathogens of nosocomial infections was gram- negative bacteria and the submission rate of etiology should be raised.
