1350例医院感染病例的调查分析

目的 了解医院感染分布特点和病原菌类型,为预防和控制医院感染提供科学依据.方法 采用前瞻性监测为主,结合临床医师报告的方法,对2009年1-12月24 257例住院患者进行调查.结果 24 257例住院患者中,1111例发生医院感染,感染率为4.58％,感染1350例次,例次感染率为5.57％；感染部位居前2位的依次为呼吸道、泌尿道,分别占76.89％、5.48％；检出的病原菌以革兰阴性菌为主,占56.70％,革兰阳性球菌占11.46％,真菌占31.84％.结论 针对医院感染现状,在医院感染率高的部分科室开展目标性监测,严格执行医院感染标准操作规程,严格规范抗菌药物的使用,加强医院感染病原菌的监测.

Investigation and analysis of nosocomial infections in 1350 patients

OBJECTIVE To explore the distribution of pathogens causing nosocomial infections,so as to provide scientific basis for the prevention and control of nosocomial infections.METHODS By using prospective monitoring combined with the report from clinical doctors,a total of 24 257 patients who were enrolled in hospital from Jan to Dec 2009 were investigated.RESULTS Of 24 257 patients investigated,nosocomial infections occurred in 1111 cases with the infection rate of 4.58%,there were 1350 case-times infected with the pathogens,the case-time infection rate was 5.57%;respiratory tract and urinary tract ranked the top 2 of the sites with infections,accounting for 76.89% and 5.48% respectively;gram-negative bacteria were predominant pathogens detected,accounting for 56.70%,followed by gram-positive cocci(11.46%) and fungi(31.84%).CONCLUSION In response to the current status of nosocomial infections,it is necessary to develop targeted surveillance by the departments at high risk of nosocomial infections through strictly standardizing the use of antibiotics and intensifying the surveillance for the pathogens causing nosocomial infections.
