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 correlation of catheter related hospital infection in hospital intensive care unit (ICU), analyze the risk factors and propose preventive measures. Methods A targeted monitoring method was used to investigate the catheter-related hospital infection in inpatients with ICU in a hospital and analyze the main influencing factors. Results A total of 914 patients were admitted to the ICU of the hospital, 72 cases of nosocomial infections were detected. The rate of infection was 7.88%. The daily infection rate of patients was 24.15 ‰, and the daily infection rate was adjusted to 5.56 ‰ by the severity of illness (ASIS). The three hospital-associated hospital infection rates were ventilator-associated pneumonia (VAP) of 42.27 ‰, CA-UTI of 1.43 ‰, and central venous cannulation-related bloodstream infections (CR- BSI) is 0.36 ‰. Age, duration of mechanical ventilation, and chronic underlying disease constitute the major risk factors. Conclusions The catheter-related hospital infection in ICU patients in this hospital is mainly VAP, suggesting that the key preventive measures are to strengthen disinfection and isolation and indoor air quality management.
