【Ａｂｓｔｒａｃｔ】　ＯｂｊｅｃｔｉｖｅTo investigate the risk factors of nosocomial infections in elderly patients with nonvariceal upper gastrointestinal hemorrhage, and to adopt reasonable protective and therapeutic measures.ＭｅｔｈｏｄｓSixty-nine cases of nosocomial infection and 141 cases of non-nosocomial infection in elderly inpatients with nonvariceal upper gastrointestinal hemorrhage cases were analyzed by logistic regression analysis retrospectively.ＲｅｓｕｌｔｓThe incidence of nosocomial infection was 32.9%. There were significant differences in mini scores, the length of hospital stay, antibiotics application, invasive treatment and underlying diseases between the two groups(P<0.05). After logistic regression analysis, nutrition status, physical force, the length of hospital stay and invasive treatment showed positive correlation with nosocomial infection(P<0.05).Nosocomial infections occurred mainly in lower respiratory tract(55.1%), urinary tract infection(40.6%), catheter-related blood stream infection(4.3%),and the main pathogenic organism of nosocomial infections was gram negative bacilli(64.6%).ＣｏｎｃｌｕｓｉｏｎｓThe elderly patients with nonvariceal upper gastrointestinal hemorrhage are vulnerable to nosocomial infections, which are closely related to the patients' nutrition status, physical force,the length of hospital stay,invasive treatment. In order to reduce the rate of nosocomial infection, the risk factors should be payed attention and proper preventive measures should be taken.
