2012年我院医院感染现患率调查结果及分析

Results and Analysis of Prevalence Rate of Nosocomial Infection in Our Hospital in 2012

目的了解我院医院感染现状,为进一步制定预防与控制感染的措施提供依据。方法采取横断面调查方法,床旁调查和查阅住院病历相结合,对我院2012年9月18日住院患者进行医院感染现患率调查。结果应调查在院患者746例,实际调查741例,实查率99.33%;发生医院感染14例,16例次,医院感染现患率1.89%,例次率2.16%;医院感染现患率居前3位的科室为ICU、神经内科、骨科,其感染率分别为33.33%、4.76%、4.71%;医院感染部位构成比居前3位的是下呼吸道、表浅切口、泌尿道,其构成比分别为56.25%、18.75%、12.50%;医院感染分离出病原菌8株,以革兰阴性杆菌为主,占87.50%;当日抗菌药物使用率37.38%,病原学送检率为30.32%。结论通过医院感染现患率调查,真实了解医院感染发生状态,有针对性对发生感染的重点科室、重点部位进行干预,降低医院感染发生率。

Objective To study the status quo of nosocomial infection in our hospital in order to provide the basis for further prevention and control infection. Methods The prevalence rate of nosocomial infection in our inpatients on September 18, 2012 was in- vestigated by a cross-sectional survey method combined with bedside investigation and review of medical records. Results A total of 741 inpatients were investigated out of 746 inpatients, and the actual investigation rate was 99.33% ; 14 inpatients had nosocomial infection for 16 times, and the prevalence rate and frequency rate of nosocomial infection was 1.89% and 2.16% respectively; the top three de- partments of high prevalence rate were ICU, department of neurology and department of orthopedics, and the infection rate was 33.33% , 4.76% and 4.71% respectively; the top three of infection body parts were lower respiratory tract, superficial incision and urinary tract, and the constituent ratio was 56.25%, 18.75% and 12.50% respectively; 8 strains of pathogenic bacteria were isolated, and gram-nega- tive bacilli （87.50%） was the mainly bacterium; the daily drug use of antibacterial was 37.38% , and pathogenic detection rate was 30. 32%. Conclusion The status quo of nosocomial infection can be learned by investigating the prevalence rate of hospital infection. The susceptible departments and body parts should be interevened to reduce the incidence rate of hospital infection can be decreased.
