目的探讨冠心病患者介入治疗后医院感染的病原菌分布及危险因素,为制定相应的预防策略、降低医院感染率提供参考依据。方法选取2013年1月-2015年12月医院收治的冠心病介入治疗患者1 784例,分析其感染率及危险因素,数据采用SPSS 20.0软件进行统计分析。结果 1 784例冠心病介入治疗患者中发生医院感染102例,感染率5.72%;感染部位以上呼吸道感染为主,共57例,占55.88%;共检出102株病原菌,以革兰阴性菌为主,共69株,占67.65%;logistic回归分析结果显示,年龄≥50岁、住院时间≥1月、心功能≥Ⅲ级、PPG>7.8mmol/L、GLU>6mmol/L、Cr≥116umol/L是冠心病介入治疗患者发生医院感染的独立危险因素(P<0.05)。结论冠心病患者介入治疗后发生医院感染率较高,发生医院感染影响因素多,临床应采取相应防治措施,切实降低医院感染发生率。
Objective To investigate the distribution and risk factors of pathogenic bacteria in nosocomial infection after coronary intervention in patients with coronary heart disease (CHD), and to provide reference for making appropriate preventive strategies and reducing the rate of nosocomial infections. Methods From January 2013 to December 2015, 1 784 PCI patients were included in the study. The infection rate and risk factors were analyzed. The data were analyzed by SPSS 20.0 software. Results A total of 102 hospital infections occurred in 784 patients with coronary heart disease, the infection rate was 5.72%. Most of the infections were respiratory tract infections, accounting for 55.88%. A total of 102 pathogens were detected, of which Gram-negative bacteria were The results of logistic regression analysis showed that the patients with ≥50 years of age, ≥1 month of hospitalization, ≥Ⅲgrade of heart function, PPG> 7.8mmol / L, GLU> 6mmol / L, Cr≥116umol / L is an independent risk factor for nosocomial infection in patients with coronary intervention (P <0.05). Conclusion The incidence of nosocomial infection in patients with coronary heart disease is high after hospitalization, and there are many influencing factors of nosocomial infection. Clinically, appropriate prevention and treatment measures should be taken to reduce the incidence of nosocomial infections.
