目的探讨住院死亡患者的医院感染特点,为预防和控制医院感染,降低死亡率,提供可靠依据。方法对本院自2006年11月至2008年10月234例住院死亡病例进行回顾性分析。结果234例死亡病例中发生医院感染98例,医院感染率为41.88%;感染部位以下呼吸道为主,≥60岁患者发生医院感染率明显升高;神经、循环系统疾病医院感染率较高;并随着住院时间延长医院感染发生率增高;医院感染具有季节性分布特点。结论死亡病例医院感染率高,可能与原发慢性消耗性疾病、不合理使用抗菌药物、侵入性操作、免疫性功能下降有关。
Objective To investigate the characteristics of nosocomial infections in hospitalized patients and provide a reliable basis for the prevention and control of nosocomial infections and mortality. Methods The hospital from November 2006 to October 2008 in 234 cases of hospitalized deaths were retrospectively analyzed. Results Among the 234 deaths, 98 were found to have nosocomial infections and the hospital infection rate was 41.88%. The main respiratory tract was below the infected area. The incidence of nosocomial infections was significantly higher in patients over 60 years old. The rates of nosocomial infections were higher in patients with neurological and circulatory diseases. With the prolonged hospital stay, the incidence of nosocomial infections increased; nosocomial infections have seasonal distribution characteristics. Conclusion The death rate of hospital infection is high, which may be related to primary chronic wasting disease, unreasonable use of antibacterial drugs, invasive operation and decreased immunity.
