我院ICU导管相关性感染及危险因素分析

INTENSIVE CARE UNIT CATHETER RELATED INFECTIONS AND RISK FACTOR ANALYSIS

目的了解医院重症监护病房(ICU)导管相关性医院感染情况,分析危险因素,提出预防性措施。方法采用目标性监测方法,对某医院ICU住院患者导管相关性医院感染情况进行调查,分析主要影响因素。结果共调查该医院ICU入住患者914例,查出医院感染72例次,例次感染率为7.88%。患者日感染率为24.15‰,经病情严重程度(ASIS)调整后日感染率为5.56‰。3种导管相关性医院感染率分别为呼吸机相关性肺炎(VAP)为42.27‰、留置尿管相关性泌尿道感染(CA-UTI)为1.43‰、中心静脉插管相关性血液感染(CR-BSI)为0.36‰。年龄、机械通气时间、慢性基础病等构成主要危险因素。结论该医院ICU患者导管相关医院感染主要是VAP,提示重点防范措施在于加强消毒隔离和室内空气质量管理。

Objective To understand the hospital intensive care unit （ICU） catheter related infections, analysis of risk factors and put forward preventive measures. Methods Targeted monitoring method was used to investigate the hospital in- fection situation of a hospital ICU catheter - related hospitalized patients, analysis the main influencing factors. Results Of 914 cases of patients in ICU, 72 cases of hospital infection were detected out, cases of infection rate was 7. 88%. Day in- fection rate was 24. 15 ‰, after adjustingt the illness severity （ASIS） , the day infection rate was 5.56 ‰. Three kinds of catheter- related hospital infection rate of ventilator associated pneumonia （VAP）, of placing a urinary catheter urinary tract infection （CA - UTI） , of central venous eannula correlation bloodstream infections （CR - BSI） were 42. 27 ‰, 1.43‰0. 36 ‰ respectively. Age. catheter indwelling time, basis of chronic disease were major risk factors. Conclusion The hospital ICU patients with catheter related infections were mainly VAP, which hint the main measure were strengthen disinfection and isolation and the indoor air quality management.
