目的 了解医院感染的流行特征。方法 根据卫生部医院感染监控小组确定的标准 ,对 1993～ 1997年 2 5 2 33例住院病人中发生的 10 88例医院感染者进行临床流行病学研究。结果 医院感染发生率为 4.31% ,1993～ 1994年医院感染率 ( 5 .7% )高于 1995～ 1997年医院感染率( 3.63% ) ( χ2 =71.2 8,P <0 .0 1) ,差异有显著意义。医院感染率以烧伤科最高 ( 9.61% ) ,泌尿外科最低 ( 1.81% )。医院感染发生部位以呼吸道为主 ,占 5 4.14 %。结论 加强对医院感染的监测与系统管理对降低医院感染率效果显著。医院感染的主要部位是呼吸道。
Objective To understand the epidemiological characteristics of nosocomial infections. Methods According to the criteria established by the Hospital Infection Monitoring Group of the Ministry of Health, clinical epidemiological studies were carried out on 1,088 hospital-acquired infections among 25,233 inpatients from 1993 to 1997. Results The incidence of nosocomial infection was 4.31%. The prevalence of nosocomial infection was 5.37% in 1993-1994, higher than that in 1995-1997 (3.63%) (χ2 = 71.28, P <0.01) Have significant meaning The highest infection rate in hospital was burns (9.61%) and lowest in urology (1.81%). Occurrence of nosocomial infections respiratory tract, accounting for 5 4.14%. Conclusion Strengthening the monitoring and systematic management of nosocomial infections has a significant effect on reducing the hospital infection rate. The main area of nosocomial infection is the respiratory tract.
