【摘要】：目的探讨呼吸科重症监护病房(RICU)住院患者发生医院感染的病原菌分布及危险因素分析,为降低RICU医院感染率提供依据。方法回顾性分析2010年5月-2015年5月医院入住RICU48h的410例患者临床资料,分析其感染部位、病原菌分布特点及相关危险因素,数据结果采用SPSS 20.0软件进行统计分析。结果 410例RICU患者发生医院感染131例,感染率为31.95%,感染部位主要以下呼吸道62.60%、泌尿道15.27%为主;共检出病原菌195株,其中革兰阴性菌、革兰阳性菌、真菌各占71.28%、18.97%、9.75%;经logistic回归分析发现RICU住院时间≥15d、气管插管、联合使用抗菌药2种、肺癌是RICU患者发生医院感染的独立危险因素(P0.05)。结论 RICU住院患者感染部位以下呼吸道为主,病原菌多以革兰阴性菌为主,发生医院感染相关危险因素较多,应采取对应措施,以降低医院感染率。
[Abstract]:Objective to investigate the distribution and risk factors of nosocomial infection in inpatients in respiratory intensive care unit (ICU). Methods the clinical data of 410 patients with RICU48h admitted to hospital from May 2010 to May 2015 were analyzed retrospectively. The location of infection, the distribution of pathogens and the risk factors were analyzed. Results the data were analyzed by SPSS 20.0 software. Results the nosocomial infection occurred in 410 patients with RICU, the infection rate was 31.95. The main infection sites were 62.60th respiratory tract and 15.27% urinary tract, and 15.27% strains of pathogenic bacteria were detected, among which Gram-negative bacteria were detected. Gram-positive bacteria, fungi accounted for 71.28% and 18.97% 9.75.The logistic regression analysis showed that RICU stay more than 15 days, tracheal intubation, combined use of two antimicrobial agents, Lung cancer is an independent risk factor for nosocomial infection in RICU patients (P 0.05). Conclusion the respiratory tract below the infection site of RICU patients is the main pathogen, Gram-negative bacteria are the main pathogens, and there are many risk factors associated with nosocomial infection, so the corresponding measures should be taken. To reduce the nosocomial infection rate.
