目的了解医院感染现状,为有效预防和控制医院感染提供科学依据。方法采用横断面调查的方法,对2009年10月22日的住院患者进行医院感染现患率调查,包括10月22日的出院患者,不包括10月22日新入院的患者。结果应查患者1129例,实查患者1129例,实查率100.0%;发生医院感染50例,医院感染现患率为4.4%,感染56例次,例次感染率为5.0%,感染部位以下呼吸道感染居首位,占41.1%,其次是泌尿道感染,占17.9%;ICU为医院感染最高发科室,感染率为30.8%,其次是神经内科,感染率11.0%;抗菌药物使用率为49.5%、一联用药为34.3%、二联用药为56.0%、三联用药为9.7%;检出病原菌38株,革兰阴性菌18株,革兰阳性菌12株,真菌8株。结论应重点监控医院感染高发科室,严格执行无菌技术操作规程,减少侵入性操作,合理使用抗菌药物,减少医院感染的发生。
Objective To understand the current status of nosocomial infection and provide a scientific basis for effective prevention and control of nosocomial infections. Methods A cross-sectional survey was conducted to investigate the prevalence of nosocomial infections in hospitalized patients on October 22, 2009, including the patients discharged on October 22 and excluding the new patients admitted on October 22. Results 1129 patients should be investigated, 1129 patients were investigated, the actual examination rate was 100.0%; hospital infection occurred in 50 cases, the prevalence rate of hospital infection was 4.4%, infection 56 cases, the infection rate was 5.0%, the lower respiratory tract infection Infection was the first, accounting for 41.1%, followed by urinary tract infection, accounting for 17.9%; ICU was the highest hospital infection department, the infection rate was 30.8%, followed by neurology, the infection rate was 11.0%; antibacterial drug use was 49.5% , 34.3% for one drug combination, 56.0% for two-drug combination and 9.7% for three-drug combination; 38 strains of pathogens were detected, of which gram-negative bacteria were 18, gram-positive bacteria and strain 8. Conclusion It is necessary to focus on monitoring of high incidence of nosocomial infections department, strict implementation of aseptic technique, reduce invasive procedures, rational use of antimicrobial agents, reduce the incidence of nosocomial infections.
