目的调查住院老年死亡患者医院感染发生率及病原菌,为降低老年患者医院感染发生率和病死率提供科学依据。方法应用回顾性调查研究方法,对我市某三甲医院2010-2012年60岁以上住院死亡病例进行医院感染发生率及病原菌检测及分析。结果 103例老年住院死亡病倒中发生医院感染46例,感染发生率为44.66%。查出感染的病原菌有6种,真菌发生率最高,占感染发生率的39.13%,真菌感染患者的55.60%为二重或多重感染。结论住院老年患者医院感染发生率高,主要病原菌为真菌感染,提示应采取有效措施加强对住院老年患者医院感染的控制与预防,以降低医院感染率和病死率。
Objective To investigate the incidence of nosocomial infections and pathogenic bacteria in hospitalized elderly patients and provide a scientific basis for reducing the incidence of nosocomial infections and mortality in elderly patients. Methods The retrospective research methods were used to detect and analyze the prevalence of nosocomial infections and pathogenic bacteria in hospitalized patients over the age of 60 from 2010 to 2012 in a top three hospital in our city. Results Among 103 elderly hospitalized patients, 46 cases of nosocomial infection occurred and the infection rate was 44.66%. Six kinds of pathogenic bacteria were detected, the highest incidence of fungi was found, accounting for 39.13% of the infections, and 55.60% of the fungal infections were double or multiple infections. Conclusion The incidence of nosocomial infections in hospitalized elderly patients is high, and the main pathogen is fungal infection, suggesting that effective measures should be taken to strengthen the control and prevention of nosocomial infections in hospitalized elderly patients so as to reduce the hospital infection rate and mortality rate.
